Hi, I follow the threads here and I have to say I cannot make up my mind about upgrading to Mavericks. So many sad stories. Am I misreading? I have a late 2012 iMac 27, 3.2 i5, 1 T SSD, 8 RAM. No freezes, no beachballs, no nothin. Couldn't run softer. I tend to like to be up-to-date but I know I'd be damn unhappy and upset if my Mac had all the troubles I read here: beachballs, SSD and Ext. HD that don't wake up and all. Is there a best way to prepare a Mac to receive Mavericks. Or should I wait until 10.10 when it comes. Thanks for the cues and hints.
