Other World Computing announced today through its MaxRAM program the immediate availability of 8GB and 16GB OWC Memory Upgrade Kits that enable owners of 2010 Mac mini, MacBook 13″, and 2.4GHz MacBook Pro 13″ computers to add up to 16GB of RAM — up to double the previous listed maximum capacity of 8GB. Like all OWC Memory Upgrade Kits, a ‘how-to’ install video and OWC Lifetime warranty are included for each Mac model.
OWC Lab Proves 16GB Capability
By maintaining its own on-site lab with the industry’s most extensive collection of Apple Macintosh computers, second only to Apple itself, OWC is uniquely positioned to perform ongoing testing and development of memory upgrade kits for Macs made over the past 25 years. This capability enabled OWC engineers to test confirm 2010 Mac mini, MacBook 13″, and 2.4GHz MacBook Pro 13″ computers are MaxRAM Certified for the following hardware and software conditions: Article Continues…
When the 2012 MacBook Pros were released, we found that SATA 3.0 SSDs—such as the OWC Mercury EXTREME Pro 6G and the Mercury Electra 6G—exhibited poor performance and reliability in the 13-inch model when installed in the optical bay via an OWC Data Doubler, while the same SSDs in the 15-inch model worked just fine.
This was similar to what happened in 2011, where (ironically enough) the 13-inch models were the only ones able to handle our Mercury 6G SSDs in the optical bay at first. Eventually, though, an Apple firmware update resolved the problems in the 15-inch and 17-inch models in the main drive bay.
As it turns out, the same thing happened to the 2012 models. Yesterday’s EFI Update 2.9 for MacBook Pro appears to have fixed the problem. Article Continues…
It turns out that Apple wasn’t content to simply release iOS 6 yesterday; Many OS X users were treated to updates as well. Granted, many of these updates added more interoperability with iOS 6, but each of these updates also addressed ongoing problems too, so you may want to update your Mac, even if you’re not planning on moving to iOS 6.
So, let’s take a look at what was updated.
- iOS 6 – This was the biggie for the day. See yesterday’s article for more info.
- OS X 10.8.2 – A bunch of little updates, including Facebook sharing integration, Power Nap support for the Late 2010 MacBook Air, and a number of iOS 6 interoperability options.
- OS X 10.7.5 – Lion users got an actual “point” upgrade, too. The most notable upgrade here is the addition of Apple’s Gatekeeper security feature.
- Security Update 20012-004 – 10.6.x Users also got at least a little something; a general security update that covered updates for 10.7.5 and 10.8.2
- Safari 6.0.1 – This adds some security measures to protect against maliciously-coded Web pages. It’s not a separate download; it’s currently only available when updating to 10.8.2 or 10.7.5
- Aperture 3.4 - This adds Shared Photo Stream support, along with other functionality and performance updates.
- iPhoto 9.4 - adds Share Photo Stream support, enhanced Facebook capabilities, new themes, and other improvements.
- Xcode 4.5 – This added 10.8 and iOS 6 SDKs, as well as other workflow updates.
- There are also a number of firmware updates. While there’s often a list of what this firmware addresses, there are often other “undocumented bonuses” to a firmware update, so you may want to upgrade anyway. You never know what kinds of extra performance benefits Apple may unofficially add, so if you’ve got one of these machines, it’s probably in your best interest to update:
And while you’re running software updates, if you’ve got Microsoft Office 2008 or 2011, you may want to hit their updater as well, as both versions just got bumped up a little. 2008 consists mostly of stability updates, while 2011 gets Retina graphics support, as well as several updates to Outlook.

About a month ago, we talked about how MacBook Pro EFI Firmware Update 2.2 “secretly” resolved problems that 2011 MacBook Pros were having with 6.0Gb/s SATA performance.
Since we posted about the fix, we’ve been hearing from customers that some firmware updates are not fully completing… even though it appears that it is. These failed updates offered no indication that the update didn’t complete.
So a bit of sleuthing on our behalf turned up the culprit. When installing the update using Software Update, the installer informs you that it is recommended that you plug in your MacBook Pro to working power source while installing. This makes sense – the one time you don’t want your battery to go out is when running a firmware update.
However, if you download the update via its Apple KnowledgeBase page, though, the description there states that you must have your MacBook Pro connected to the power connector for installation.
From all the reports we’ve seen, it would appear that the KnowledgeBase instructions are the more accurate or at least more specific. Connecting the power supply while updating your firmware isn’t a recommendation; it’s a requirement.
Taking that requirement mindset even further is that when installing any firmware update on any Mac notebook, make sure you have it connected to its wall outlet power adapter before you start the update. Then, after running the updater, check the Hardware Overview screen in System Profiler and see if the the correct new Boot ROM or SMC version number for the update you’re running is present. If you still have the old version, then you will need to run the update again.
Naturally, this connect to power requirement is already solved for desktop machine users. But if you can think of a way to update a desktop machine like an iMac, Mac Pro, or mini without being connected to power, we’d like to hear about it!
Apple released MacBook Pro EFI Firmware Update 1.8 on December 8th, 2009, sparking a new interest in the Late 2008 MacBook Pro models and their maximum memory capacity.
Apple supports up to 4GB of memory in these machines, but OWC has done the testing with our memory modules and has been able to support 6GB of memory since their release. However, there was something interesting we found with our testing when trying to qualify the laptops to accept 8GB of memory. Simply put, while System Profiler recognized that there was indeed 8GB of memory installed, once more than 6GB of memory was actually put to use, the performance of the overall machine diminished.
Of course, when we heard the rumors circulating again that the Firmware Update may have silently addressed this issue as well, we got excited and performed the qualification testing again after installing the update. Unfortunately we found the same scenario on all the machines. The machines were faster the more memory we installed until more than 6GB was present. Once the machine tried to address the final 2GB of memory the performance started to suffer yet again.
It would have been nice to officially support twice the memory that Apple intended, but alas, we’ll have to settle for a 50% increase. Which all in all – isn’t bad.
The machines that were rumored to go to 8GB, are supported to only 4GB by Apple, and have been tested and confirmed by us to 6GB are:
MacBook Pro 15″ 2.4GHz (All)
MacBook Pro 15″ 2.53GHz model w/ExpressCard Slot (Late 2008)
MacBook Pro 15″ 2.8GHz model w/ExpressCard Slot (Late 2008)
MacBook 13.3″ 2.0GHz (All)
MacBook 13.3″ 2.4GHz (All)
White MacBook 13.3″ Intel Core 2 Duo 2.13GHz
