I'm having a big problem with some (but not all) of my emails coming up as blank in Apple Mail. If I forward the email to my Yahoo address I can read them fine so the information is there - but Mail won't display it. This seems to be worse with some senders than others, and seems to be affecting more and more senders as time goes by. Also, some emails appear mostly blank with just a few weird symbols (a square with a question mark inside).
So far I've installed the latest version of Catalina 10.15.4, gone through and deleted a bunch of old emails to clear space, tried rebuilding a sample mailbox, and disabled all my apps that install at login, but I'm still having problems.
If I reboot my Mac in safe mode the emails are all there and readable, but as soon as I go back to regular mode the problem comes back. HELP!!!
If it is a corrupt plist you can try— quit the mail.app
and Delete the com.apple.mail.plist from Finder>Go>Go To Folder, copy and paste:
~/Library/Containers/com.apple.mail/Data/Library/Preferences/com.apple.mail.plist
relaunch the mail.app and test. The plist will automatically rebuild itself.
if no change you can always Control click the deleted .plist in the Trash>Put Back
If no resolve the next attempt—
Quit mail.
From the Finder>Go>Go to Folder, copy & Paste:
~/Library/Containers/com.apple.mail
Highlight all the contents in this folder. Place your mouse on the selection,
Then Control click (right-click) and choose "New Folder with Selection”. Do not move the new folder from this current location.
You can close the Finder window.
The next step will be to restart the Mac and test
After the computer is restarted, open the Mail.app> Preferences to see if it opens properly.
