Maybe Too Early to Be Sure But ... (Solving MacBook Pro Sleep Problem)
My (fairly new) MacBook Pro had developed some rather tedious behaviours such as sometimes not going to sleep when the lid is shut or not waking up when asked to. Also wireless networking performance had been rubbish…
So, figuring they were hardware problems (a friend had many hardware problems with his first revision MBP), I backed up the whole machine, ready to go off to Apple for repair … I thought I'd also reinstall the OS whilst I was at it.
Hey Presto, sleep problems solved. Wireless networking problems solved. Bonus. I‘m just going to have to be very careful about what software I put on in the future … I’m guessing it was a 3rd party app, that wouldn't shut down properly or something.
