Updating firmware on macbook pro
I've got an early 2011 Mac Book Pro (8,1) and I am trying to install the newest EFI firmware upgrade, however it only supports 10.8.5 and 10.9.5.Unfortunately I have no clue as to what the best course of action would be to get this installed.If you have a late model Mac that does not have an optical drive you do not need the firmware restoration software.Your Mac is able to recover on its own from a firmware update error.Many Intel Macs, that include a built-in CD/DVD drive, have the ability to restore corrupt firmware to a known good state by using a Firmware Restoration CD available from Apple.(Apple supplies the firmware as a download; you supply the CD.)When Apple removed the CD/DVD drive from Mac models, they realized that an alternate method of recovering from a corrupt firmware installtion was needed.We won't know if that's included in today's update until the company updates its Update History, which could be anytime between now and next week.
Even better you can use the following tips to create your own Recovery HD on any volume, including a handy USB flash drive you can carry around with you.
Mac firmware restoration is the process of resetting your Mac's internal firmware to a known good state.
This is a basic method for fixing a firmware update that has problems, becomes corrupt, or, for any number of reasons, fails to complete.
Some firmware updates are also available as downloads you can install manually.
If your Mac needs a firmware update and it isn't installed automatically, check to see if a manual updater is listed below.
