The logs are listed on the stack overlow link.

pg_ctl: could not start server
 
You might be misunderstanding where I said restore, I did not backup the database, I restored an Operating System because I changed out my hard drive for a solid state drive; therefore, I had to restore my Operating System from Time Machine/(backup).

Trying to start the server, I navigate too: /Library/PostgreSQL/12/bin

from bin, I ran: sudo -u postgres ./pg_ctl start -D /Library/PostgreSQL/12/data

pg_ctl: could not start server
 
 
What do the logs say...
 
When I ran the status command instead of start, it of course eluded to not running.
I mention all of this with the caveat that I did recently restore from a backup because I replaced my HDD with a SSD.
 
 
You should be very specific as to how you restored your database from backup because there is a good chance this wasn't done properly and you presently have a corrupted database on your hard drive.
