Description of problem: first-generation MacBooks (at least mine) use an Intel T5600 CPU, so x86_64 support should be available (alsp cpuinfo is showing the lm flag=64bit). When using the efidisk.img of x86_64, the MacBook won't use/recognize the prepared usb stick. You will have to use an i686 image, so the MacBook recognizes the usb-stick with an bootia32.efi runnable. Version-Release number of selected component (if applicable): rawhide/snap-3 How reproducible: Always. Steps to Reproduce: 1. Get a 1-gen MacBook. 2. Prepare usb-stick with x86_64/os/images/efidisk.img and boot Actual results: macBook will not recognize the problem Expected results: MacBook will recognize the usb-stick and start anaconda, including efi support. Additional info: Preparing an usb-stick with i686/os/images/efidisk.img works. But will 64bit support be available? might this be a bug in the MacBook firmware?
