Have you played around with the new options for volumes in APFS? In the past you had to partition your disk to make multiple boot volumes off of one disk, and that was always with a degree of risk and stress. But with the new file system you can make “floating” volumes basically, they only use as much space as they need, and can be easily added and deleted on a whim. The end effect is identical to an external drive install or partitioning, but without the hassle or added expense.
Now on to the matter of how unreasonably difficult and geeky the procedure is to perform a proper OS install on a fresh new drive, or to upgrade to a clean system and bypass the typically messy in situ upgrade procedure…
Thanks Ioa. I’m not feeling very geeky at the moment and I have a lot of other things to do which more than fill up my time, so I shall continue to wonder for the moment.
The SSID on this iMac is only 500GB and as I use it for video editing with Final Cut Pro X, whose library files can be enormous, I need to preserve as much space on the drive as I can, so a “floating drive” would go against that.
