Hi, I’ve experienced a bootloop problem after I accidentaly popped USB drive while installing High Sierra. Now the computer is in bootloop. I’ve tired: Resetting PMC, SCM. Nothing is responding (CAPS Lock light indicator is green) Cannot boot to recovery (CMD+R), safe mode (shift).
I have another mac and I’ve ordered a Thunderbolt cable to maybe reinstall it somehow via target disk mode.
Any input would be good.
Popped as in removed the flash drive while High Sierra was installing? If the flash drive still works and has the High Sierra installer on it you should be able to start the installation again by holding the alt / option key after pressing the power button on the MacBook to switch it on. Refer to this apple link on how to boot off an USB Mac OS installer, look under ‘Use Startup Manager‘: https://support.apple.com/en-au/HT202796
