MacBookBro67 Posted November 20, 2015 Share Posted November 20, 2015 I have a MacPro 1'1 - This may not be the best place for this post but I couldn't find a netter one. I am attempting to build an iEl Capitam hacked installer with Tiamo's modified boot.efi. I have successfully built a Mavericks installer, and an El Capitan installer. I boot holding down the opt key and choose the USB key with the installer. Everything seems to work just fine like the installation menu is about to pop up but instead it jumps back and completes the boot every time from the hard drive.

blacksheep Posted November 20, 2015 Share Posted November 20, 2015 You should use Pike's boot.efi for Yosemite and ElCap, not the Tiamo one. The latter works only with ML and Mavs. If you've already used the correct one, bless El Capitan volume/system folder. 1 Link to comment https://www.insanelymac.com/forum/topic/309489-this-is-strictly-a-macpro-11-question/#findComment-2190037 Share on other sites More sharing options...
