I am currently in the process of resetting an old 2012 iMac after deciding trying to set up the Fusion Drive in there was too much hassle. I think it can be done but as it is a proprietary RAID setup I decided to reinstall MacOS and then use an external drive as a dual boot Linux/Mac setup. I had this before and it worked well enough, the only requirement was to hit the boot drive selector shortcut....
Change Mac Machine Name via Terminal
I needed to change the name of one of my Macs remotely and this is the command to do it:
sudo scutil --set HostName [NewHostNameHere]
SMB Mac 11.3.1
Apple in its infinite wisdom changed the settings for Samba ‘SMB’ protocol and killed access to my NAS server, thanks Apple not like I wasn’t using it all the time.
I found a fix online, don’t trust me check if there are any risks in this fix:
Create or edit this following file and add the 2 lines to the file.
~/Library/Preferences/nsmb.conf
[default] protocol_vers_map=2
