This problem just started today! MAIL IS SLOWING DOWN:  I open Apple MAIL 6.2 on my MBP-13" running Mountain Lion 10.8.2  --- Has run since July 2012 when I installed Mountain Lion (and fine before that in LION etc.)

 

OK but just today when I type as I am now, or use TextExpander (as I have used for years)-- the typing becomes slow-- everything slows down-- but NOT in other applications such as TextEdit or Safari or any other-- just MAIL.

 

I did a full restart of my Mac-- OK back to normal speed for 30 minutes, but then a slowdown.

 

I quit MAIL and now it is back and for now it is "normal" again--- but if anything like the earlier part of the day, it will begin slowing down soon…

 

What could be causing this slowdown that does NOT affect other programs?

 

Thanks for any thoughts here.  I use MAILTAGS with Apple Mail - but have for 2 years and never a problem.

 

Best regards,

    Well I need some help here.  After 30-90 minutes my MAIL program has slowed to a crawl.  Restarting gets the typing and general movement from eMails to mailboxes back to normal, but withing 30 to 90 minutes it has slowed down.  I also notice my Mac seems to be working harder-- fan coming on and that is quite rare.

     

    Any ideas if I have a virus here or ???

     

    Only notice this is Apple Mail right now, not in any other programs.

     

    Best regards,

    I am having the exact same problem. I will close mail and it returns to normal speed for about a day or two.

    Anxious in Georgia:

     

    Try this, it worked great for me.  (Do a full backup first, and you'll have to reset your toolbar in Mail, but that is quickly done and the speed is back to full!):

     

    Please follow these instructions to delete the Mail "sandbox" folder.

    Back up all data.

    Triple-click the line below to select it, then copy it to the Clipboard (command-C):

    ~/Library/Containers/com.apple.mail

    Quit Mail.

    In the Finder, select

    Go Go to Folder

    from the menu bar. Paste (command-V) into the box that opens, then press return. A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selectedfoldernot just its contents — to the Desktop. Leave the Finder window open for now.

    Relaunch Mail and test. If the problem is resolved, you'll have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Post your results.

    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.

     

    Best regards,
