Hello donmarshall57,

Thanks for using Apple Support Communities.


If you're seeing what looks like a lightning bolt symbol on the screen of your Mac, then it appears it has been mistakingly booted into target disk mode. Simply restart your computer without any buttons held down, and your Mac should start up normally.


Share files between two computers with target disk mode


Take care.
