I run my Mac Pro (2014) from a 1TB SSD because at the time the ‘disc’ storage fixed at 250 GB was not upgradeable. I upgraded from Mavericks through Mojave over the years, but stuck with Mojave until now. I find now that valuable upgrades of 3rd party software items that I need will only run on OS11 or later. I took the plunge and made two separate bootable backups of my system, using Carbon Copy Cloner. Via the invitation given by ‘About this Mac’ I took the plunge and went for it. It offered Monterrey. All went smoothly with software upgrading phase – no surprises – but it was late when it prompted that it was copying Monterrey to the SSD system disk. It told me that there remained only 9 minutes, so I went to bed. I took a last-minute peek however, and the process was continuing but now said 13 minutes. This morning I found that the screen was showing a start-up sequence – a thermometer bar under the apple logo, with the bar stuck halfway. Several attempts to force shutdown and reboot the (supposedly) Monterrey ssd arrive at the same final point every time. I know that the processor is working hard by the temperature which gets to 44 C. Mercifully my Mojave backups work just fine, so all is not lost. But can anyone suggest a ‘next move’ for me?
