FALLOFMAN Posted June 11, 2016 Share Posted June 11, 2016 I had a dual boot of yosemite on one HD and windows on the otherTried to upgrade to el capitan through the app store but it would start installing and just restart back into yosemite so I wiped the mac HD and decided to prepare a usb stick in windows 10 with transmacI tried the official app store el capitan app and used installesd.dmg rebooted my pc, set boot priority to the usb stick. Screen goes black for half a second then windows startsThought it might be the download to I tried it with el capitan macpwn version and the exact same thing is happening.Anybody know why?
