Brian Richardson Posted December 13, 2014 Share Posted December 13, 2014 Can it be done better? I had to use other software to build usb - any other install method I tried failed. On the same 755 i have installed Lion, reimaged to MLion, and now reimaged to Yosemite. Lion went on fine with almost no issue, I had to fix App store login issue. MLion no real issues that I can remember other than needing to use an Extra Folder found on a YouTube video. Yosemite the only issues I have had is installing, once installed it has been fine. One big thing I had to do was in my Bios - latest from Dell A22 - was switch from ACHI to ATA it was the only way the installer did not panic or just not see the Drives.
