Installed EC on my macbook late 2008 (8gb ram and mac mini mid 2011 (16gb ram)last night and wish I hadn't MB worked for about 30 mins then froze, on restart no boot, used disk utility which told me my HD was completely full with one "Other" file. Have tried everything, tech tool, disk warrior, disk utility, nothing will fix it!! have just ordered a new drive Mac mini worked but had spinning beach ball constantly, repaired permissions, disk utility foundd nothing but no joy. Tried logic pro, couldn't run any of my projects, hard drive couldn't keep up whereas under Yosemite it was never a problem and my Digidesign Mbox 2 is not supported so totally screwed. Decided to uninstall but thats no easy job either, been up all night and have finally got back to Yosemite but had to erase HD to do it so now faced with reinstalling all my software. not a good night!
