I noticed that after a system reboot my new USB SSD (SanDisk Extreme Portable SSD) attached via USB-C to an MacMini 2020 is not available until the first user has logged on (interactively using the GUI).
On this MacMini a daemon is running which requires access to the external USB drive directly after a reboot before any user has logged on (because this MacMini runs at server and therefore nobody ever will login).
What do I have to configure in Catalina to make my USB SSD available before the first user has logged on?
The daemon that should use the external SSD is started via registered plist in
/Library/LaunchDaemons/ using the following flags:
I have formatted the external SSD as APFS (case sensitive).
