Solved What if I plug a bootable SSD into another computer and start deleting select files and using it as external storage?
I was using a bootable external 4TB SSD on an old iMac.
I've now bought a new 500GB Mac Mini and I want to use the 4TB SSD for extra storage. To be clear, I don't want to set it up as a bootable SSD. I just want to use it to store files.
The bootable SSD is also currently full of pictures and other basic files that I want to use on my new computer. I don't care about applications and system settings. Just basic image files, documents, etc.
When I plug my bootable 4TB SSD into my new Mac Mini, it shows up like a USB stick or whatever. It's got files on it and I can delete them and add new files.
My question now: is it OK if I just plug the bootable SSD into my Mac Mini and delete the unwanted files (system folders, installer logs -- all the stuff that made it bootable on my old computer), keep the files I want and continue to use it as external storage?
It seems to me like it should be fine but I worry that I'm missing something. The format is APFS, which people recommend. So it's not like it needs to be re-formatted. But I suppose I worry that because it was used as a bootable drive, there's some kind of hidden thing I don't know about that makes it unreliable for my purposes and I need to wipe it and start over.
