How to automatically mount Thunder Bolt drives at boot on Mac mini?

I have received an answer from the vendor of the external drives.

This apple forum post shows the trick.

As near as I can tell, there is no settings option for this.

Open a terminal and copy and paste the following command. You will need to enter your password.

sudo defaults write /Library/Preferences/SystemConfiguration/autodiskmount AutomountDisksWithoutUserLogin -bool true

I’ve tested this on an M1 Mac Mini with Sequoia and my Pegasus mounts on boot without logging into the GUI.

I just tested it and it appears to work as desired.

The new M4 mini is running Sequoia 15.4.1 .

It boots and runs fine, and will mount the two external drives only after logging into the GUI . It will NOT mount the drives if I just SSH into the system but will mount them if I use "share screen" from a 2nd Mac.

After several hours of testing, I can say with confidence that things are now working as expected.

Thanks to Rich (from Promise?) for the fix:

sudo defaults write /Library/Preferences/SystemConfiguration/autodiskmount AutomountDisksWithoutUserLogin -bool true

The old Mini (2014 edition) was purchased with the optional "server" software which may be why it worked.

Where might I find documentation covering the boot process?
