Macbook Pro late 2013: MAIL won't close often, have to FORCE QUIT
Also, cannot delete a message in MAIL when I am viewing it. If I delete it from the list, sometimes it works, sometimes I get a message that it cannot be deleted.
MacBook Pro with Retina display, OS X Yosemite (10.10.3)
A
Back up all data. Rebuild the mailbox. Try again to delete the message.
B
Please take these steps to delete the Mail "sandbox" folders.
Step 1
Back up all data.
Triple-click anywhere in the line below on this page to select it:
~/Library/Containers/com.apple.mail
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selected folder—not just its contents—to the Desktop. Leave the Finder window open for now.
Restart the computer. Launch Mail and test. If the problem is resolved, you may have to recreate some of your Mail settings. Any custom stationery that you created may be lost. Ask for instructions if you want to preserve that data. You can then delete the folder you moved and close the Finder window.
Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.
Step 2
If Step 1 doesn't solve the problem, repeat with this line:
~/Library/Containers/com.apple.MailServiceAgent
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
