Fix for slow Mac Mail performance

Darrel Bayani -

Problem

Apple Mail is very slow in it’s response. Message lists take ages to update and the app itself seems to pause for 15-20 seconds.

Cause

The SQL database that Mail uses to catalog your email addresses needs a bit of housekeeping now and again, you really need to have a tidy up!

Solution

First quit Mail – then:

For OSX Lion (10.7) and Mountain Lion (10.8) you need to do the following:

  1. Open the Terminal App – You can find this by using spotlight and typing terminal.
  2. Copy and paste this command into the command line of Terminal:
    sqlite3 ~/Library/Mail/V2/MailData/Envelope\ Index vacuum;

For Snow Leopard (10.6) you need to do the following:

  1. Open the Terminal App – You can find this by using spotlight and typing terminal.
  2. Copy and paste this command into the command line of Terminal:
    /usr/bin/sqlite3 ~/Library/Mail/Envelope\ Index vacuum;

You should now find that Mail runs much faster.
