@selje Yes, and I may do later on. I do not want to mess with dual boot with macOS (I'm not sure that works). I really want to keep my macOS available for a long while if I find any file/sw I have forgotten that is mac-centric, and also one sw I am not certain how I should handle.

(Actually, I have been thinking that it could be fun to buy a semi-old iMac at a good price because their screens are good, and replace with Linux.)

My macbook pro I spoke of is dual booted. At boot up it prompts you with a nice apple and penguin logos to chose which OS to use.
I did this along time ago, had to free up space on the hard drive and repartition it, the with the help of an app 'refit' or something like that, it created the two options in the boot partition. then one just fired it up in the linux side with the installer cd or thumbdrive in place and started the install of linux. I saw lots of links for 2014 mac mini's

@hehemrin
makes sense. These types of efforts have given me more than a few gray hairs.

@selje :-) I would have trouble with file management when to move what, because duplicate would not work spacewise, and I assume technically impossible to share a home folder partition. Furthermore, the 8 GB RAM works but is at the lower end for photo editing, esp if later get a more pixelhungry camera. But it's definitely worth to keep in mind for ideas for how I can use my macMini later on. Thanks for your comments!

That's where rsync comes in. It is unparalleled at file transfer. I have never seen an app that comes close to the features it has. All from the command line. It even supports ssh. It is available on all unix based OSes which includes Macs. Even for just moving files locally its features are mind boggling. You may already have used it, but if not I would highly recommend it. It even has a test option so you can build a command and test without worry.

@selje No, I haven't used it itself. But seems as a tool I should learn how it worls. I have used it as engine in eg Timeshift backup. BFor file backup, I'm thinking of evaluating Borg backup, both on external drive and eventually also eventually for cloud backup (encrypted). Another interesting tool is Syncthing I also may try, to sync files between devices via local network.

@ike Thanks and good luck to explore Linux beyond WSL! I have tested WSL a little with Debian on Win 10, but I think it is better on Win 11, I have however not dived deeply into WSL. Many Linux distros can be run as live-usb, so you can explore without installing. Ventoy is a good sw so you can have multiple distros on same usb - I have actually not tested Ventoy yet, but from what I've heard it is an excellent sw for this purpose.
