After releasing the iPhone OS 3.0 last week and several other software applications with the occasion, Apple has now released a firmware update for the new MacBook Pro EFI notebooks it introduced at the 2009 WWDC (Worldwide Developers Convention) that took place at the start of the month – the update is entitled MacBook Pro EFI Firmware Update 1.7. Apple also released a firmware update for the iMac entitled iMac EFI Firmware 1.4.

According to Apple, the MacBook Pro EFI Firmware Update 1.7 is meant to allow the device’s drives to use transfer speeds in excess of 1.5Gbps. The iMac EFI Firmware 1.4 Update is meant to correct some improper display issues affecting iMac machines fitted with ATI Radeon HD 4850 graphics as well as solve an wake-from-sleep BootCamp problem.

“MacBook Pro EFI Firmware Update 1.7 addresses an issue using drives based on the SATA 3Gbps specification with the MacBook Pro introduced in June 2009. This update allows drives to use transfer rates greater than 1.5Gbps, however Apple has not qualified or offered these drives for Mac portable computers, and their use remains unsupported. All previous and current Apple portables with a SATA drive interface include a SATA 1.5Gbps hard drive. iMac EFI Firmware 1.4 Update addresses issues where iMac computers with ATI Radeon HD 4850 graphics intermittently stop responding and addresses wake-from-sleep issues in Boot Camp,” Apple explained.

Several Apple products are affected by the issue the update addresses: MacBook Pro (13-inch, Mid 2009), MacBook Pro (15-inch, Mid 2009), MacBook Pro (15-inch, 2.53GHz, Mid 2009), iMac (24-inch, Early 2009), iMac (20-inch, Early 2009).

If you would like to download the MacBook Pro EFI Firmware Update 1.7, a download location is available here.
If you would like to download the iMac EFI Firmware Update 1.4, a download location is available here.
If you would like to apply any of the two updates, detailed information on how to do so is available on Apple’s Support site here.
