Installing Yosemite was a nightmare. I tried the 8GB thumb drive technique (i watched youtube video) no go, I literally reinstalled Yosemite 10,10 (after i backed up all data of course) still did not delete.. Finally, I said **** it and cleaned it out, backed up his system spent 90 bucks on 8 gb of ram for his computer... his computer is a lot faster now... plenty of space on hard drive and external hard drive...

Installing windows is sweet... installing Mac OS X Yosemite oh hell no!!! Thank you guys again for your help Shay..
