OSX Mail App Corrupt - OS Reinstall?
I am running a late 2009 iMac with OS High Sierra 10.13.6 as the latest it will update to.
I use AOL mail via the OS mail application - version 11.5 (3445.9.7). Unfortunately, this has become corrupted and try as I might, I have been unable to restore the various IMAP and SMTP settings within the app. I am not confident enough to do a fresh instal of the whole OS and am therefore currently using AOL webmail which works ok but I would like to continue to use the OS mail app as I have done for years.
I have a Western Digital 'My Passport Studio' permanently plugged into the iMac but have never has to restore anything from it.
My question, therefore, is: 'can I somehow reinstall the OS Mail App alone from a backup in 'My Passport/Time Machine' or would I have to completely reinstall the OS to get the OS Mail app back to its former glory?'
