Swapping HD between two Macs

[Giuanniello]

A question,

I am using my old MBPro 15" with High Sierra, it runs off of a 1TB SSD I recently bought, I also have a dead 27" iMac with a 500GB SSD which was also running High Sierra; a late 2012 MacMini should come in in place of the iMac and since it will become the Mac to host my photography software and archive I'd prefer to have the 1TB disk of the MBPro in the Mini and the 500TB off the iMac to take place of the 1TB in the MBPro, question being, simply swapping disk from one machine to another would cause any problem?

Grazie

It will not cause any problems in your case.

With High Sierra, a system disk taken from one Mac to another should boot but you may have issues with the keychain. So in testing this, Safari web passwords won't transfer, customized network settings may have some issues. I don't have iCloud or other Apple i-Services but these may be affected. Hardware passwords (Airport Extreme, probably encrypted disks but I haven't tested this) should transfer. If you have passwords stored on the disk that you can't remember or if you have customized network settings that you can't re-create, it's better to use Migration Assistant with the disk you have (meaning you would have to get a different disk as the system disk) or with a Time Machine backup. The reason for this is that keychain items tied to a computer's MAC (media access control) address are no longer valid.
