The day after releasing an update to fix a problem in MacBooks Air which could generate more battery consumption with the lid closed, today Apple has also released the MacBook Air EFI Firmware Update 2.8.
This second update is intended not only for MacBooks Air released in mid-2013, but also for early 2014.
According to Apple, the new update improves the reliability of the machines when returning from the mode sleep and when booting with certain USB / Thunderbolt devices connected. In addition, it also fixes a ?rare? memory problem that could cause the system to restart at random, as well as a bug that prevented the system from entering sleep when an external monitor was connected and running Windows via Boot Camp.
The MacBook Air EFI Firmware Update 2.8 weighs just 4.8MB.
