How do you upgrade the RAM in the "Unibody" Aluminum 13-Inch MacBook models? What type of RAM do they use? How much RAM do they actually support?
How do you upgrade the RAM in the "Unibody" Aluminum 13-Inch MacBook models? What type of RAM do they use? How much RAM do they actually support?Please note that this Q&A explains how to upgrade the RAM in the Aluminum "Unibody" MacBook models shipped in 2008 (model identifier MacBook5,1). This should not be confused with the 13-Inch "Unibody" MacBook *Pro* models, which EveryMac.com covers separately.
EveryMac.com also provides RAM upgrade instructions for the "White & Black" MacBook models shipped from 2006-2009 (model number A1181) and the White Polycarbonate "Unibody" MacBook models shipped from 2009-2010 (model number A1342).
Upgrading the memory in the "Unibody" Aluminum 13-Inch MacBook models -- the MacBook "Core 2 Duo" 2.0 13" (Unibody) and "Core 2 Duo" 2.4 13" (Unibody) -- is not quite as simple as it is for the earlier MacBook models, but it still is easy.

Identification HelpThe Aluminum "Unibody" MacBook models are particularly easy to spot as they're the only Apple notebooks made from a silver-colored aluminum case that say "MacBook" on the lower display bezel. If your Apple notebook is branded "MacBook Pro" rather than just MacBook, it is a different model. EveryMac.com covers RAM upgrades for the 13-Inch MacBook Pro models separately.
Both Aluminum "Unibody" MacBook models use the same type of RAM, and the above visual information likely is sufficient for unique identification.
However, if you are the type to appreciate precision, these models also can be collectively identified externally by the 2254 EMC Number in tiny print on the bottom of the notebook toward the hinge and in software by the MacBook5,1 Model Identifier.
EveryMac.com's Ultimate Mac Lookup feature -- as well as the EveryMac app -- also can uniquely identify these systems by their Serial Numbers and more.
Additional details about specific identifiers are provided in EveryMac.com's extensive Mac Identification section.
Official RAM DetailsThe Apple Support Site has a detailed article on "How to Install Memory" in the Aluminum "Unibody" MacBook that provides much of what you need to upgrade the stock memory, but not everything.
This document starts by noting that the Aluminum "Unibody" MacBook models:
Have two memory slots that you access by removing the access door, battery, and bottom case. Your MacBook comes with at least 2 GB (1 GB in each slot) of 1066 MHz Double Date Rate (DDR3) Synchronous Dynamic Random-Access Memory (SDRAM) installed.
Both memory slots can accept an SDRAM module that meets the following specifications:
- Double Data Rate Small Outline Dual Inline Memory Module (DDR SO-DIMM) format
- 1.25 inch or smaller (3.18 cm)
- 1 Gigabyte (GB) or 2 Gigabyte (GB)
- PC3-8500 DDR3 1066 MHz Type RAM
Official & Actual Maximum RAM CapacityOfficially, Apple only supports 4 GB of RAM in the Aluminum "Unibody" MacBook.
Initial tests at the time these models shipped from site sponsor Other World Computing and the always excellent BareFeats demonstrated that they were capable of stably supporting 6 GB of RAM with one 2 GB module and one 4 GB module. It was physically possible to install 8 GB of RAM as well, but the system was not stable and it was not recommended to install 8 GB of RAM.
However, some time after OWC and BareFeats published their findings, EveryMac.com readers and other third-parties reported that these models were capable of stably supporting 8 GB of RAM.
In detailed follow up testing, OWC was able to confirm that the Aluminum "Unibody" MacBook models are capable of supporting 8 GB of RAM, but if -- and only if -- they have been upgraded to run Mac OS X 10.6 "Snow Leopard" or higher and have Boot ROM Version MB51.007D.B03. Note that you may be required to manually update the firmware for the update to work properly. Earlier versions of the operating system (OWC tested running Mac OS X 10.6.6) and earlier Boot ROM versions are not supported.
RAM Upgrade Video InstructionsThe Apple document provides installation instructions complete with drawings, which absolutely should be read in their entirety before one installs memory. Even better, though, OWC provides a convenient step-by-step video of the process:
How to Upgrade Your PC's RAM
Below, we'll tell you how to diagnose a memory shortage and what to do about it. To see how a RAM upgrade is done, check out our companion video.
How do I know if I need more RAM?Check your PC's RAM usage by opening Windows Task Manager. Press Ctrl-Alt-Del (Vista users will have to click Start Task Manager) and click the Performance tab. If the figure next to 'Available' (or 'Free' in Vista) under 'Physical Memory' hovers around zero and your PC seems sluggish, you need more RAM.
How much RAM do I need?The average Windows XP user should be satisfied with 1GB of RAM. Our tests, which involve working with images and using Nero Express to burn CDs, ran one-third faster when we upgraded from 512MB of RAM to 1GB. Power users who simultaneously run lots of demanding applications, or anyone regularly working with digital video or other large graphics files, will want at least 2GB. If you're planning to upgrade your PC to Windows Vista, you can still get away with 1GB, but for a more comfortable experience we recommend 2GB of RAM.
What kind of RAM works on my PC?RAM comes in many flavors, including DDR, DDR2, and DDR3. Newer technologies offer faster performance, but most motherboards accept only one type of RAM. Check your PC's manual to find out what type of RAM modules you need and how they have to be installed. RAM dealers such as Crucial and Kingston offer handy online tools for identifying the right RAM for many PCs and motherboards. Most PCs being upgraded today use dual-channel memory, which you must install in pairs for maximum performance, so adding two 512MB modules instead of one 1GB module may be better. Again, check your documentation.
Paying a few dollars more to buy RAM from a reliable manufacturer like Crucial or Kingston is usually worthwhile, as RAM quality isn't the place to save a few bucks.
What do I need to add more RAM?Tools: You'll need an antistatic wrist strap for grounding yourself. Your local computer store should have one for less than $15.
Documentation: Some motherboards require module pairs to be placed in specific banks, or pairs of RAM sockets. Consult your documentation before starting the upgrade.
Update, 24 June 2015: After some confusion, Microsoft has clarified that Windows 10 Insiders running the preview build will get the final version and get to keep it. You just need to keep opted in for pre-release updates. "Since we’re continuing the Windows Insider Program you’ll be able to continue receiving builds and those builds will continue to be activated under the terms of the Windows Insider Program," explained Microsoft’s Gabe Aul.

Update, 17 June 2015: At E3 2015, Microsoft confirmed it will bring Xbox-only games to Windows 10 including Gears of War: Ultimate Edition and Killer Instinct. "We’re going to allow people to play on PC, to play on console, to play back and forth.” Re-watch the press conference here.
Update, 1 June 2015: Microsoft today announced that Windows 10 will be available beginning July 29 in 190 markets around the world. Customers with PCs and laptops running Windows 7 and Windows 8 will be able to get Windows 10 as a free upgrade. Consumers will have one year from July 29 to take advantage of the free upgrade.
Once a Windows device is upgraded to Windows 10, Microsoft will continue to keep it current for the supported lifetime of the device—at no cost. Those who want to be among the first in line for the free Windows 10 upgrade can reserve a free copy in the coming weeks.
Build 10130 of the Windows 10 Insider Preview is now available for the Fast ring. Cortana is fully working for UK users, but there's still no support for streaming games from the Xbox One. The new web browser - Microsoft Edge - also features Cortana. You can right-click on just about anything to 'Ask Cortana' for more information.

Windows 10 UK release date: When is Windows 10 coming out?
The latest build of Windows 10 is available to insider testers now. If you have a compatible Lumia Windows Phone you can even try out an early version of the mobile Windows 10. (See: How to install Windows 10 now and how to install Windows 10 on your phone.
The final version will ship as soon as this summer 2015. Microsoft announced today that Windows 10 will start to roll out on July 29, in almost 200 markets around the world. Previously, Microsoft at Microsoft's re-born WinHEC conference in Shenzhen, attendees were told that Windows 10 will roll out in 190 countries and 111 languages.
Kevin Turner, Chief Operating Officer at Microsoft had said in late 2014: "By next late summer and early fall we'll be able to bring out this particular OS (operating system). That's the current plan of record," according to Reuters. This means Windows 10 is slightly ahead of schedule, and the upgrade will be ready to go in late July or August. We will bring more details of the UK launch as we have them.
At Build 2015, Microsoft said that Windows 10 will launch in several staggered events from summer onwards, each geared toward different devices with PCs coming first. "The way to think about it will be a launch wave that starts in the summer with PCs, and fills out over time as more devices come online," said Joe Belfiore, corporate vice president of the operating systems group at Microsoft. There's still not a confirmed date for any of these launch events, though Belfiore said that Microsoft is still on track for this summer.
"You should expect [the] phone, HoloLens, Xbox, and Surface Hub [launches] will be staggered," Belfiore explained, because of the complexity of coordinating hardware and software launches.
Although Microsoft was present at CES, it scheduled a Windows 10 event in Redmond back in January in order to "talk about the next chapter of Windows 10". Terry Myerson, Joe Belfiore, Phil Spencer and Satya Nadella all presented. See also: How to watch Microsoft's January 21 Windows 10 event and live blog.
Windows 10 UK price: How much will Windows 10 cost?
Windows 10 will be free to end users. At least it will be a free upgrade for a lot of people. Users of Windows 7, Windows 8.1 Update, and most Windows Phone 8 devices will be able to upgrade to Windows 10 on their devices, for free. This is guaranteed for the first year of the new OS's shelf life, but we would be surprised if it didn't remain free - depending on uptake. For more detail, see Will my PC get Windows 10?
It was also discovered that the Raspberry Pi 2 might be able to run Windows 10, and that it would be freely available to those customers.
Enterprise customers are not part of the deal, however. Jim Alkove, director of programme management, wrote in a blog post:
"Windows 7 Enterprise and Windows 8/8.1 Enterprise are not included in the terms of the free Windows 10 upgrade offer we announced last week, given that active Software Assurance customers will continue to have rights to upgrade to Windows 10 enterprise offerings outside this offer, while also benefiting from the full flexibility to deploy Windows 10 using their existing management infrastructure."
When we started this article we said that we thought Windows 10 would be free to consumers, although not to OEMs who purchase licences to put on PCs and laptops they sell. Microsoft had previously declined to answer direct questions about how much Windows 10 will cost, particularly for people upgrading from Windows 7 or XP saying, "we want to talk about the overall product family [at this stage]". But now we know, as expected, that the Windows 10 upgrade will be free.

Microsoft is hoping to make the upgrade as pain-free as possible for these users, with direct upgrades allowing settings and apps to remain in place. However, XP and Vista users must do a fresh installation if they want to use Windows 10. And they will have to pay.
As of 26 June 2015, Microsoft has officially announced that Windows 10 will cost the same as Windows 8.1 in the UK. That means Windows 10 Home will cost roughly £80 and Windows 10 Professional will cost around £140. These are the prices you'll pay for Windows 8.1 currently from Amazon.
Suffice to say that in the face of Apple giving away OS X, and declining PC sales, it was always unlikely that Microsoft would charge for Windows 10. Add in the fact that Windows 10 is aimed at smartphones and tablets just as much as desktop PCs and laptops and you can see that there really isn't much of a market for selling the upgrade.
How to reserve Windows 10So, how do you get your hands on a copy of Windows 10? Windows has organised a reservation service for Windows users to guarantee that they get Windows 10 on launch day. How will it work? Automatic download of course!
If you’re currently running either Windows 7 or 8.1, you should see a notification pop up in the lower-right corner of your screen informing you that Windows 10 is coming and that Microsoft is offering a limited time free upgrade. If it doesn’t pop up, have no fear – click the small Windows icon in your task bar and it should appear.
The icon should appear if you’ve got Windows Update enabled, but if you don’t, there’s another way to register. You just have to navigate to the Control Panel and click on the Windows Update menu.
Click on “reserve your free upgrade” in the app window and enter your email address to confirm that your registration has been approved. Once the OS is released on 29 July, you should receive a notification that allows you to schedule the installation time at a time that suits you. The update should’ve already been downloaded in the background.
Installation time may vary between computers, but Microsoft claims that it could take as little as 20 minutes on a high spec machine – so we estimate it’ll take around an hour for regular PCs. At least you don’t have to wait for the download first!
It’s worth noting that you’ll still be able to download and install your free copy of Windows 10 without reservation, but you won’t have it pre-downloaded in the background.
What about Windows Phone 10?Windows 10 will run on phones, tablets, laptops and PCs. It will not be called Windows Phone 10 on smartphones: it will be Windows 10 Mobile. The Technical Preview was made available in early February, and Gabriel Aul, the head of the Windows Insider program and point man for Microsoft's Windows 10 technical preview program, confirmed the launch of another Preview on April 10.
While Microsoft has dramatically increased the number of phones that Windows 10 preview supports, there's a small piece of bad news: the Lumia Icon and its international variant, the 930, won't be part of the update. For the full story, see: Windows Phone 10 UK release date, price and new features. and How to install Windows 10 on your phone
New features in Windows 10Perhaps the biggest news about Windows 10 is that it will be - in Microsoft's words, "One product family, one platform, one store". For the desktop version of Windows 10, there will be no more 'duality', as Microsoft's Joe Belfiore put it. That means no more split personality between modern apps and the 'old' desktop.
Here are what we think are the best 10 new features in Windows 10, including Cortana, multiple desktops, a proper start menu and more.
Windows 10: why is it called Windows 10?During the short briefing in San Francisco when Microsoft unveiled Windows 10, it made it clear that the next version would be very much unified across all types of devices with screen sizes from 4 inches to 80 inches. It confirmed that the next version of Windows Phone - after 8.1 - would be 10 and said, "This product, when you see the product in your fullness I think you'll agree with us that it's a more appropriate name."
When questioned about ARM-based Surface tablets, the answer was, "we're building the software to update vast majority of devices out there." However, it has now become clear that Surface tablets won't be upgradeable to Windows 10.
Microsoft's Terry Myerson summed it up with, "Windows 10 represents the first step of a whole new generation of Windows, unlocking new experiences to give customers new ways to work, play and connect. This will be our most comprehensive operating system and the best release Microsoft has ever done for our business customers, and we look forward to working together with our broader Windows community to bring Windows 10 to life in the months ahead."
Windows 10: What's Bill Gates got to do with it?The co-founder and former CEO of Microsoft has been working with the company on a project called Personal Agent, which is in essence an advanced personal assistant.
"One project I am working on with Microsoft is the Personal Agent which will remember everything and help you go back and find things and help you pick what things to pay attention to," he told Reddit. "The idea that you have to find applications and pick them and they each are trying to tell you what is new is just not the efficient model - the agent will help solve this. It will work across all your devices."
Below follows the rest of our original article containing all the rumours building up to the September 30th event:
A leaked document, obtained my Myce.com, shows some interesting details about Windows 9, including the 'fact' that the Preview version is scheduled for release between "Q2-Q3 2015". This means the official launch is unlikely to be in April 2015 as previously thought. The Q2-Q3 window is huge, of course, and the Preview could therefore appear any time between April and September 2015. It's possible there will be Christmas 2015 launch to consumers and, given that everything never goes to plan with a new Windows launch, we wouldn't be surprised if you can't buy a new laptop, PC or tablet with Windows 9 until then.
The document has a section detailing 'update items' which include changes to the Metro UI (Microsoft still calls the modern UI Metro internally, apparently), Windows Defender, OneDrive and improved Windows activation. There's also a mention of Cortana, Windows Phone 8.1′s personal assistant, which could mean it's coming to Windows 9.
Windows 9 Technical Preview leakedAhead of the 30 September event, the Windows 9 Technical Preview has been leaked on Winsupersite. The build number is 9841, although the site in unsure whether this is the exact build of the public Technical Preview.
Plenty of information (which we've outlined below) has already been available about Windows 9 including the return of the Start Menu - although it combines the old style Windows 7 style with Windows 8 Starts Screen functionality. New information is that the feature will be resizable.
We've heard that the Charms bar (that bit which pops in from the right) would be gone from Windows 9. However, Winsupersite says that it's still present on touch-based systems but can only be accessed with touch, not a mouse pointer.
Task view (above and shown in one of the videos below) is used to switch between apps and is opened via a button on the taskbar. File Explorer, meanwhile, will open with a new Home view as the default, showing things like favourite folders, recent folders and recent files.
Windows 9 leaked videosBefore we even get to 30 September, videos supposedly showing Windows 9 have been leaked online. They show a unified Notification Center, demonstrate multi-desktop (Task view) and the start menu. Watch the videos below but bear in mind that things could change by the time the final version arrives.
Windows 9: No Charms barWinbeta claims that in Windows 9, Microsoft will do away with the Charms bar – that menu which pops in from the right with buttons like search, share, start and settings. However, the site is talking about Windows 9 on the desktop as the feature will remain as it is on tablets - this matches up with the information from Winsupersite above.
If you're wondering what the new regime will be, Winbeta said: "One method that we heard about that stands out is having a button up near the window controls that once pressed, would reveal the Search, Share, Devices and Settings charms from the top of the window (there's no need for a Start Button for desktop users in the charms.)"
"Another idea Microsoft have been toying with is removing the Charms completely. While it's possible, we're not entirely sure how that would work," it added.
Windows 9: Start menu returnsAs we explain below we are certain that the new Windows update known as 'Threshold' will grow up to be Windows 9. And we expect Windows 9 to launch at some stage in early 2015, probably April 2015. This week we have seen what its claimed are leaked screenshots of Windows 9. Just to confuse things, these shots are labelled 'Windows 8.1 Pro', but that is consistant with what we have been hearing about the Threshold build that will eventually become Windows 9.
Windows-watchers at Myce.com and Neowin have shown off screenshots of the new Start menu in Windows 9. There's also a shot of the new Windows Store in Windows 9. Click the Windows 9 screenshots to view them at full size.
Windows 9 screenshots
Microsoft hasn't lost its taste for uncomfortable compromise, however. Strong rumours suggest that the expanded Start menu will appear within a more 'Desktop' Start screen and in the Desktop for PC- and laptops users. But that the same, expanded, Start menu may take over the entire Start screen for tablets and other smaller touchscreen devices.
Now look over to the right for another symbol of the same movement. To the right of the apps list is an area with pinned Metro apps. So as now you can see from the Start screen live tiles for important apps such as weather, mail, news, and calendar. Just as now the new Windows 9 Start screen is customisable, it seems, but here you can also pin Desktop Windows software. On both sets of screenshots you can see icons for the Pictures and Documents folders, as well as what looks like a 'My PC' tile that gets you straight into the file system.
Windows Phone 9Talking of Cortana, the document also mentions Windows Phone 9, which is tagged alongside Windows 9 for a Q2-Q3 Preview release. We're only just seeing new smartphones running Windows Phone 8.1 - the first version to feature Cortana - but in a year's time Windows Phone 8 will be consigned to the history book. Let's just hope that existing hardware will be upgradeable and that owners don't end up in the same situation as Windows Phone 7 buyers did.
Based on Microsoft's Build 2014 developer conference, we've put together an article looking at the future of Windows - beyond even Windows 9.
Microsoft partners will be getting a pre-beta version of Windows Developer Preview 9 soon, we understand. Thus those partners will have seen the earliest version of Windows 9 before the Build conference this April.
We expect to see a single beta of Windows 9, which will likely appear in the summer of 2014. If everything goes perfectly it is possible that Microsoft will release a Release Candidate version at the end of August or the beginning of September 2014. That date could easily slip.
Once a RC is released, bugs will be collected and fixed for several months before the final code is released to manufacturers. On this basis, it makes sense to see a Preview version from April 2015 onwards. (See also: How to use Windows 8: 10 tips to get you started on Windows 8.)
Windows 9 featuresWe expect that Windows 9 will be 64-bit only, although we expected that for Windows 8 and we were wrong. A lot depends - as ever with Microsoft - on what OEMs want to build, and what Intel gives them with which to build.
One thing that Microsoft has to do is allow Windows Phone and Windows RT apps to run on both Windows Phone and Windows. Even Xbox apps should become cross compatible. You may also be able to pin Metro apps to the taskbar. Also expect to see Kinect-based 3D gestures to be enabled for laptops with 3D cameras - basically the ability to control your computer with gestures.
Microsoft's recent pronouncements suggest a full return of the Start menu and that Windows 8-style apps will be able to run on the desktop. Windows 9 will definitely be less traumatic a chance for desktop users.
One key - although less obvious - development is likely to be much improved power management. The rise of mobile devices has made battery life a key battle ground for Windows. Intel has done its part, massively improving power management with its latest generation of mobile processors. But the Windows software needs to keep pace, so expect Microsoft to make great claims for Windows 9's power management capabilities.
