Fixing a Mac Typing Lag

    My MacBook Air 2010, running OSX Lion, has been very sluggish of late, with typing in a new window often lagging by a second or so. I’ve had plenty of other problems with the unit too, but I think I’ve fixed the lag through a process suggested here:

    • Shut down your computer.

    • Hold the Option key while turning it on (hold the Option key down for a little longer than the power key.)

    • From the top options, select Recovery HD.

    • Select Disk Utility.

    • Select your hard drive.

    • You can try all the repair and verify options, but the one that seemed to be the problem for me (and the author of the solution) was Repair Disk Permissions. It found a number of issues.

    • Once it’s finished—assuming it’s found and repaired something—restart your computer.

    Thanks xraydoug.
