STOP sign and non Recovery Mode
My late 2019 iMac has crashed and will not let me into Recovery Mode. I made a bootable drive with High Sierra BUT the iMac will not run the install. It just shows a STOP sign and then a few moments later shuts down the iMac. Apple Store installed the software onto the erased drive and it was working for a couple of days but showed a problem by not being able to run MS Office 2019. It just kept asking for a licence. MS were unable to help me. Apple the same. The drive just refuses to do anything.
Help!
