I don't know how it happened -- I was reviewing my email on my old MacBook Pro, running Sierra, and somehow managed to send all of my Apple Mail Inbox emails to the Trash, and then they disappeared. Unfortunately, I did not back up the MBP. But, I have email being stored in the Cloud and am constantly backing up with Time Machine on my iMac, running Catalina. I am trying to restore Mail using Time Machine from the date before I noticed all of the emails were gone.
When I clicked Enter Time Machine, and selected the date I need to restore, Mail did not appear in the list of applications in the Finder. I went to the hard drive and found the Applications folder there, and found the Mail application, selected it, and clicked the Time Machine Restore button. This error message popped up:
“” can’t be modified or deleted because it’s required by macOS. I checked the Trash and did not find the emails there.
Is there any way I can restore all my emails using another method?
Apple Discussions have not directly answered my question, given all the steps I have taken.
