We got a call from a customer with a couple of MACs in there place and one of them was giving the following error “the macos installation couldn’t be completed”. There are a couple of options out there to fix this and able to get the user back up and running, but only after doing a “reinstall os” option.

This video was a good start; however, the “restart” option didn’t work. Start with the “command button” and “r”  to get the recovery dialog box.

Let us know if this helped you…
