Given the age of my wife's iMac 2011 I decided to use a spare SSD to use in the event of her HDD crashing. The instructions on the Apple website seem unnecessarily complicated (Create a bootable installer – Apple Support (UK)). I note these are from the UK website so maybe it just hasn't been updated.
Provided the full High Sierra 10.13.6 has been downloaded the install asks where you want it installed. I had initially formatted the SSD as AFPS but that wasn't recognised so presumably it is only later versions that can use it.
I reformatted it to macOS extended and it installed successfully. I then used Carbon Copy Cloner to clone from the HDD to the external SSD and rebooted to the latter. That worked fine but for some reason Startup Disk wouldn't allow me to restart from the internal HDD so I had to shut down manually, unplug the SSD and restart.
The SSD is a SanDisk Extreme and, as I understand they are not as reliable as other SSDs, I will store it away until needed. How easy is it to boot up after an internal HDD has crashed?
