Mail under Mountain Lion is painfully slow / unusable

So what's your contribution? Do you have a solution? There are *many* people here and in **many** other threads on this exact subject.

I'm still waiting for your contribution to the discussion, not just wasting bandwidth.

I have contributed here and in other threads on the topic, just not to rude, arrogant people such as yourself, who show no manners and jump in on a reply to another poster just to try to sound self important. Either do more extensive reading on your and the other *quote* 'dozens and dozens' of users or make an appointment at an Apple Store. Seeing that I have never referenced you at all, I will just ignore your personal and non-productive abuse.

Good Luck. Your attitude says you will need it. 😉

Amen, but watch out they may start crying and ban you from the forum because you have a real problem they cannot solve and when that happens they get upset as you may have noticed! Apple is perfect and so is everyone that sends you a link to help solve the known problem so if you don't give them "solved my problem" they say you are ranting and have your question removed or they bash you because they cannot solve the problem.

Hanging / Frozen mail OS X 10.8 is this a solotion to. But the mail is now crazy and attachment is view in ASCI text now. Hmmm.

Check the forums before crying Dude. Apple is not here. Maybe try contacting Apple directly instead of crying here. Read the TOU here before deluding that you are talking to the Apple Help Desk. Everyone here is a bit like you, just more understanding that we just try to help each other with issues. Unfortunately you expect the Cavelry. Contact Apple directly if you want to rant. We can't help you here.

Cheers

For what it's worth - I searched for and deleted all traces of Norton Utilities and that seems to have resolved this same issue for me.

Yep, Nortons will do that to a Mac.

Hello,

I confirm that MAIL has become extremely slow between the version of the Lion and Mountain Lion.

Mail seems to have now some difficults to manage IMAP mailboxes. Besides the problems of indexing SPOTLIGHT.

I re-install OSX on my machine (a clean INSTALL). Symptoms and problems are still present...

Symptoms are :

• - EXTREME SLOW the computer
• - MAIL the software stops responding
• - Overuse of RAM
• - Overuse of the CPU resource
• - Unable to pick up the new messages
• - Spotlight wants to index the new messages and then over-used resources (CPU + RAM)

What were the changes in the MAIL software (source code, database, etc.) that have slowed the performance?

Thanks

Let me join the throng in thanking you. I think there has been an update which alleviates the need to delete the contacts. When I uncheck Contacts in iCloud a dialog box says "delete contacts on this Mac" or such. Easy Peezy. Anyway it works magnificently.

I had the exact same problem and tried various solutions on this discussion board. None of them worked (although I appreciate the willingness of others to offer solutions) and went to the genius bar instead. The Genius ultimately deleted five files from my computer which did the trick:

data.data

window_1.data

window_2.data

window_3.data

windows.plist

Apparently these files are meant to remember the state of your computer and if any of these have any funky data in them, it can have wide ranging affects on the system and Mail in particilar.

I don't know the exact location of these files as he flew through a bunch of windows, but hopefuly that helps.

It looks as if Apple have now fixed the problem, with the 10.8.5 upgrade.

Hi All,

After update to 10.8.5 my both home and work Mail.app started to work very slow and often just stuck (in Activity window shows endless 'Fetching').

I've done password reset thing (restart then 'command+R') )and also deleted SyncServices and com.apple.mail.

This is a bit increased averall speed, but still way slower compared with 10.8.4 and totally unresponding with office365.com mail account.

Please help

Curious, mine Mail app is still working well whereas with 10.8.4 it was 'painfully slow', especially at the start. Perhaps it depends on the mail server.

This previouse posting works for me.... though i have to do it every few months

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.
