My MacBook Pro w Touch Bar is having display issues. I am trying to boot it in Target Disk using another MBP. I have connected via a Thunderbolt 2 to Thunderbolt 3 adapter. I believe the damaged MBP is starting in Target disk, but it does not show up on the host Mac.
i have checked disk utility and desktop settings. No disk mounting.
MacBook Pro with Touch Bar
should work like this:
Transfer files between two Mac computers using target disk mode - Apple Support
if you want the files off the magenta-screened Mac, you need to put that one in target mode, and its disk should mount as the second disk on the working Mac.
Check the settings in Finder preferences (not to be confused with SYSTEM preferences) to be sure they will show you mounted drives on the desktop. Default is to NOT show.
Thank you - this is what I’ve been trying. Through the lines I can see what I believe to be the bouncing thunderbolt icon that shows up for target disk. But it is not appearing on the desktop of the working mac.
