MacBook Air (Mid 2013) Battery Drain – Firmware Update

MacBook Air SMC 2.0 Firmware UpdateHere’s an important firmware update (SMC 2.0) for all of you MacBook Air (Mid 2013 model) users out there.  Apple have just released an SMC firmware update (2.0) for all mid 2013 MacBook Air models which addresses an issue where your MacBook Air can use an excessive amount of battery when the lid of your Air is closed.

I’ll definitely be updating my MacBook Air as I’ve noticed that the battery does occasionally seem to drain a little quicker than I’d expect with the lid closed.

There are two methods to perform this update either via the ‘Software Update Tool’, which can be found in the Mac App Store or by downloading the update from the Apple support article here.
