EFI boot menu manipulation for macOS, like efibootmgr Topics. So I upgraded my Mac Pro with the efi for the Macbook Air. When turn on mac and hold option button and the "EFI BOOT" appear as installing windows. Its freezing for a moment and will reboot again. Knowing how touchy the boot sector is on a mac especially with Boot Camp I would be inclined to leave it. ybnsned bgz bjcfi egano ukqb klls oxa zmpyx aismk yvrusu
