Apple issues iMac Graphic, MacBook Pro EFI firmware updates

Apple this week issued a pair of firmware updates, resolving a flickering graphics issue in late 2008 15-inch MacBook Pro models and addressing a hanging graphics issue on iMacs.

iMac Graphic FW Update 3.0

The iMac Graphic FW update fixes a graphics issue that could cause Apple's all-in-one Mac desktop to hang "under certain conditions." The 481KB download requires OS X Lion.

MacBook Pro EFI Firmware Update 2.8

The MacBook Pro firmware update is recommended for 15-inch, late 2008 models. The fix resolves a graphics issue that may cause the internal display to flicker. The file is a 1.79MB download and requires OS X 10.5.8, OS X 10.6.8 or OS X 10.7.3.

Apple has released a slew of EFI updates in recent weeks. Last month, the company issued several updates for 2010 Mac models that added support for Lion Recovery over an Internet Connection.

Other recent updates include a Wi-Fi update for the iMac and EFI firmware stability fixes for 2011 Mac models, including the MacBook Air, iMac, MacBook Pro and Mac mini.

It's great that they're fixing all these long-standing firmware bugs. Maybe they have a new guy, made himself the EFI guru.

I haven't experienced these issues, but then I haven't upgraded to Lion. So were these issues always there, or did they come along with Lion? I'd really like to know.

5 years to fix an issue! Why even bother.

I have a 2008 MacBook Pro and just completed the firmware update. Went very smoothly. My OS is Lion and I have never experienced any flicker problems, just wanted to keep my machine up to date. I am wondering if this update in some ways prepares the machines for Mountain Lion, but Apple is not saying so?
