I don´t know if this is Jamf related, but have an issue with an Mojave client
When turning on the Macpro it shows the apple logo and the load bar shows as always, but then is gone and nothing happens more and only a black screen.
In safemode it is the same thing and have of course tried the SMC/NVram reset also
Have tried to go to diskutility and do a disk check and all seems ok. And tried to do a re-install of mojave(without deleting existing installation of course), but afterwards still same error
I have tried single user mode, but it does clarify anything for me.
Any one has some good ideas ?
If the machine is not booting to the system at all normally I would try alt booting that machine. (Holding the Alt key while booting) and then selecting Macintosh HD when it appears. I this doesn't boot to the system then I would recommend completely wiping the machine and re installing macOS.
I hope the user has a backup!
