Hi all,
Apologies if this is in the wrong section of the forum.
I have two bootable HD's in my Mac Pro, early 2009, 3.46 GHz 6 core Intel Xeon - the original HD running Mac OS 10.10 which I no longer use and a 1TB SSD which I'm pretty sure is running OS 10.13. I've been using this SSD as my main bootable drive for about 5 years now.
A couple of days back the cursor froze and I had to force shut down the computer, on restart I got the utilities recovery screen. I scanned the SSD with utilities and it reported back a clean bill of health, but I'm no longer able to boot the SSD drive - the Apple logo appeared and then a circle with a line through it, and then it booted to my original HD (which I'm now using). When I go to 'Startup Disk' in system preferences the SSD is not recognised at all.
I understand this circle with a line through means the SSD contains an OS not suitable for my computer, how has this happened?
Any tips as to how to fix this would be greatly appreciated.
I've got a fairly recent back up on time machine on an external hard drive.
Many thanks. P
