You know what. I just restarted my Mac, went to recovery boot disc and then did a repair disk permissions on the partition that had OS X Mavericks installed. Restarted and all seems to be fantastic! Couldn't be happier. Hope it is a permanent fix!

Yes, mine was an in-place upgrade. I think I will do the clean install as the last resort but I was wondering if there was an easier fix...

I second Crucial as well. Their online RAM compatibility tool is just awesome. The last thing you want to be worried about is spending $ for RAM that won't even be accepted by your Mac or Windows PC.

Hi guys. Am new to this forum here. Sorry to start out with a question straight away. I did search the forum for previous discussions about this but couldn't find anything really helpful. Ok, the skinny is that my Mac's performance sucks after installing OS X Mavericks. It is really, really slow. I came across this post - Mac slow after Mavericks - Fix it and it suggests a few different things. A lot of people have commented that the tips work but I was wondering if some OS X expert here could really give me the green signal to try them out. The last thing I want is a corrupted Mac. I would rather deal with a slow one!
