I’m writing this on my MacBook Air. Typically, when I’m at work, I would be using my MacBook Pro. Unfortunately, it is not working at the moment because I tried installing the new version of the Mac operating system, Mavericks.
I downloaded it overnight. (No idea how long.)
I installed it this morning. (About an hour before crashing.)
Restarting my computer, I got a message that the install failed because of some problems on my hard drive.
The message defaulted to an option suggesting I re-install OSX, which I’m doing (Now, about 36 minutes left.)
Did I mention that I was doing this with a hardwire into the internet, not over wifi?
I suggest waiting a while before upgrading, unless you are one of those people like me who won’t listen to his own advice.
