I rescued my old 2008 MacBook Pro and did install macOS Catalina (almost latest) and Solus latest, both installed on their own SSD. Until I get an adapter to put both SSD inside I use one, take it off and place the other inside, just for test. Solus is amazingly fast on this 'Obsolete' status MacBook Pro. Windows installer failed to even boot 😁
After install Solus booted incredibly fast, shutdown even faster, all fine. But next two times I got this trying to shutdown the computer:
[514.587140] : Failed to remount ´/´read-only: Device or resource busy
[514.593981] systemd-shutdown: Failed to finalize file systems, ignoring.
What does this mean and what can I do?
