Pardon us for our initial skepticism on this larger memory capacity finding.

You must be running Snow Leopard or later to address 8GB on these systems, and our testing was done with 10.6.6, which is the earliest version weвЂ™re currently supporting for this. Once you have ensured that the Boot ROM is the correct version, make sure your Operating System is updated to OSX 10.6.6.

LATE 2008 MACBOOK PRO LATEST OS INSTALL

If your Boot ROM version does not match the numbers above, download the appropriate firmware updater for your model machine and install according to the instructions:

If you have installed that update, your Boot ROM version will be 06.В If you have this update installed, youвЂ™re already able to install the 8GB without any problems and donвЂ™t need to perform further updates to install more RAM.

** IMPORTANT NOTE: EFI Firmware Update 2.8В was released on Februfor the Later 2008 MacBook Pro.

Machines with other Model IDs are not affected and donвЂ™t need an update.

MacBooks with a Model ID of MacBook5,1 should have a Boot ROM version of 03.

MacBook Pros with a Model ID of MacBookPro5,1 should have a Boot ROM Version of 05.

Next, check the Boot ROM Version in your System Profiler.

How do you ensure your Late вЂ08 MacBook/MacBook Pro can address 8GB of RAM?ДЇirst, you want to make sure you have one of the affected models: Once we manually installed the вЂњupdatedвЂќ version of the EFI Firmware in our test machines, they were able to address 8GB normally, without any crashing or slowdowns.

LATE 2008 MACBOOK PRO LATEST OS UPGRADE

Those who didnвЂ™t upgrade until after Apple changed the updater got the newer firmware, which allowed proper addressing of 8GB. The practical upshot of all this is that if you installed the EFI Update when it first came out, like we did, you would have gotten the old code, which meant your computer would only address 6GB properly. Unfortunately, Software Update doesnвЂ™t show this version as being different from the previous one, so users wouldnвЂ™t be notified if they had already updated their firmware to the older version.

Whether any other elements were affected by this change is undetermined, but it did change memory addressing with the later version of the update installed, you could address a full 8GB in Snow Leopard. However, it seems that somewhere along the line, Apple changed this update without notating it anywhere. In late 2009, an EFI Firmware Update was released to address the buzzing noises coming from the optical drive. The results were exactly the same as in 2009, lending credence to our conclusions, but the sheer number of claims to the contrary led us to continue searching-and the trail ended at Apple.

This was contradictory to our testing in December 2009 which quite clearly showed that while these models recognized a full 8GB, if an application addressed more than 6GB, the system would slow down significantly. This time around, it came in the form of Tweets directed to us, as well as in posting in popular Mac forums.ДЄs it turns out, several other memory vendors-along with some Late 08 MacBook/MacBook Pro users-have laid claim to these machines working with 8GB of RAM. Every once in a while, a blip on the radar comes up, letting us know that thereвЂ™s something not quite right in our little corner of the Mac Universe.
