Let me save you a huge headache — don’t set an EFI password on your Mac unless you have the original receipt for that machine.

If you buy your Mac off Craigslist, like I did, and your daughter writes half a novel for her high school class but never backs it up elsewhere (note – always back up your stuff!), and then her MacBook Air suddenly won’t boot up, the EFI password the previous owner put on the laptop will prevent you or Apple from accessing the hard drive or ever using the computer again.

Hypothetically, of course.

If you don’t want to have to tell your daughter she loses her computer and will need to wait a week while you find a way to connect her SSD to another Mac and find her files, disable that EFI password now.

Here’s how.

If you have a MacBook Air from mid-2011, you may have noticed intermittent issues where your laptop has a harder time waking up from sleep mode than it normally would have done, and when it does, the fans might loudly blast as if the whole laptop were on fire.

Although rare, these issues have been afflicting customers for at least the last couple of years. But it seems like Apple has finally figured out what’s wrong, as a new update today specifically for mid-2011 MacBook Air owners fixes the longstanding issues.

According to Apple, “This update resolves a rare issue where MacBook Air boots or wakes to a black screen or becomes unresponsive. This update is recommended for all 11-inch and 13-inch MacBook Air (late 2010) models. ”
