Since the update to Mavericks Mail app uses more than 50% of cpu as long as it is running (temperatur of CPU is about 85 °C, fan about 6000 rpm). Yesterday it discharged fully charged battery in 1,5 hours (normally lasts about 4 hours). Has anyone a solution?
MacBook, OS X Mavericks (10.9)
I have a same problem. Mail takes 3-10minutes to startup, CPU usues more than 100% and takes more than 10minuetes to sattle the CPU.
I try some tips that I found online like,
- Mail update for Mavericks v1.0
- reinstall Mavericks
- rebuild inbox
- delete Cache.db / com.apple.finder.plist file
- terminal “defaults delete com.apple.mail ColorQuoterColorList”
- Delete all file(s) within this folder of which names begin with "Envelope" (tip from WalterCHuber)
All of them didn't hlep my problem.
Now I try to open the Mail beforehand and close it while working. I hope I can use Mail normally again. Please includes this problem solution in the next update.
I run OS X 10.9 (2.3GHz i7 16GB RAM), migrate from OS X 10.8.5.
This helped me too, however there is yet another process in the Activity monitor running, called mail.content, the same as the last, so to be clear, I had 2 processes called mail.content in the Activity monitor using 98-102% of the CPU at any given time whilst the mail application was open, just so you know, no other applications were open simultaneously.
I could find no further informtation but did have a look at the activity window from within Mail and noticed it cahcing and so on back and forth, so I did a mail check this opened additional proceses in the activity window, once the mail check had completed and synchronised, I then stopped the other 3 processes, by selecting the Stop sign, each one for one of my mail accounts, I just did it, I couldn't care less, my system is backed up to the minute and I have had enough of this, it has happened since Mavericks install, no change, I have not edited the mailboxes or anything such like since maverick update. Maverick has sent numerous updates..
This solved the issue, the mail app is way down the list on as you can in the picture attached, I am not sure what additional effects this may have, if so I will post back here, however I simply could not wait any longer problem finding the, mail is synched and updated as I type and I did a check to make sure it did not change the CPU usage incase it got linked into a check/update/sync cycle.
Not sure if this helps, but it was through all these mail's I came to my decisions, that the activity was in a cyclic position of not letting go for whatever reason, I have 2 IMAP accounts and 1 POP account, upgraded from Lion recently, on a MBP, my iMac is yet to have these issues.
Deleting the Envelope Index files finally also helped me: after a few days the CPU usage dropped down to a normal level. Thnx !!!
The only unpleasant effect of the re-indexing is that to old emails incorrect dates have been assigned... (in fact the date when the re-indexing was performed). Probably the headers of these email do not conform to modern standards. Nevertheless, it's annoying because earlier versions of Apple mail indexed these email correctly...
With so many and so different bugs I'm wondering whether Apple has developed this software newly from scratch?
Does this tend to happen when the laptop is unplugged or is it constant?
I was having issues and after days of Googling I finally found a working answer.
Hopefully it can help a few of you guys as well.
I finally gave up on trying to use Mail. After trying every potential fix, the problem only seemed to get worse. I thought I had a semi-fix by leaving Mail in the background or minimizing it until I needed to use the app but that didn't work either. I still was hit with the Maxed Out RAM dialogue box.
So now I'm using an app called Airmail. $2 from the app store. Great app. Works with a bunch of different mail services and with just a minimal amount of tweaking (hiding certain sidebars) looks 99% like Mail. And it syncs up with Evernote, Dropbox, Google Drive, etc. for some useful features.
Best of all: It doesn't devour my RAM for unknown reasons!! Worth every penny.
Similar saga here. I spent a tad more (MailPlane), but I've gotten my money's worth just being able to stay logged on to multiple gmail accounts and view each inbox with a click. Attachment management was a pleasant surprise also. When/If the Mail fix from Apple shows up, I'll be hard pressed to decide which to use.
it certainly looks like the latest update from apple has fixed the problem! #happy
The 10.9.1 update was supposed to improve Gmail support, but I am still having essentially the same symptoms as before, There may have been a small improvement in that Mail eventually gets to a state where is's "caught up" and not constantly using CPU time, and it may not take quite as long as it did before 10.9.1. It could also be that the CPU utilization has gone down somewhat, but my system still feels sluggish while Mail is churning away.
In Mai's Activity window, I see these things the most, all related to my Gmail IMAP accounts:
1) Synchronizing with server
2) Updating cache directory
3) Communicating with server
It's getting closer to something I could live with, but it still seems to using a lot more system resources than it did in Mountain Lion.
I had the same issue. Was also having problems with Safari running with high CPU loads. Removed the envelope files. And that didn't seem to work. I was having issues with a different program, and that program's tech support suggested I do a key chain repair. Now my CPU usage is normal again.
I had the same problem. After migrating from my old late 2006 MBP running Lion, to a brand new late 2013 rMBP running Mavericks, the Mail 7.1 Application constantly utilized one processor to a full extent, making a joke of the declared 9 hour battery life (reducing it to 3 or so).
I have spent several evenings investigating with no luck.
Only after I have made a grand pruning of old items, the problem went away. I cannot pinpoint the sole responsible, as all actions were executed in one batch (I suspect either the spelling library or internet plugins - as the Mail App kept running threads called "web content").
List of actions done (replace xxx with username), Mail and Safari must be stopped:
Removed inactive and unreachable email account (deactivated the account).
Deleted Envelope files from:
/Users/xxx/Library/Mail/V2/MailData/
(se other threads for instructions)
Removed old 3rd party spelling library from:
/Library/Spelling/
/Users/xxx/Library/Spelling/
Removed unused, old or unwanted Safari plug-ins:
/Library/Internet Plug-Ins/
/Users/xxx/Library/Internet Plug-Ins/
Removed unused or unwanted startup items from:
/Users/xxx/Library/LaunchAgents/
/Library/LaunchAgents/
/Library/LaunchDaemons/
Viola, after a full restart and rebuild of Envelope files, Mail App is docile keeping its paws off my CPU when nothing is asked of it.
This solution, from Apple Support, worked for me. It is much simpler, quicker, and less technical than others posted here:
1. Quit your Mail app.
2. While holding down the Shift key, restart Mail. This will delete the "temp saved app states that might have accumulated, confusing the OS."
When I did this on my desktop Mac, CPU usage spiked and fell for a while, occasionally going up to near 100%, often hovering around 50%, but within a couple of hours, it was so far down the list on Activity Monitor that I didn't even see it. And it automatically fixed the same problem on my MacBook Air, without having to do anything.
I had called Apple to see if they could help me, since I didn't understand some of the other solutions posted on this and other forums. The first person was clueless and kept going off to check with his supervisor, who eventually took over. The restart while holding the Shift key was the first thing he suggested, and it worked!
They both claimed that this problem (of Mail using over 100% CPU after upgrading to Mavericks) was unusual, not something they were familiar with, etc. This was a surprise to me, judging from the many threads discussing this issue.
Hope this helps someone!
This is not normal. Eithrr you have a corrupted install of 10.9, or you have some incompatible 3rd party add-on.
Or - if you just installed, it may be converting and indexing - give it an hour if so.
Mail works grea for me. I have 6 accountsnad > 12GB of local files, 4k IMAP messages and right now my mail is taking up 0.0% of my CPU.

SOLUTION WORKS!!!!!!!!!!!!!!!!!!!:
I noticed that my Accounts.plist file in ~/Library/Mail/V2/MailData had grown to a massive 70 MB. Simply deleting this file fixed the issue (the new Accounts.plist is only 10 KB). I had to set up my Gmail accounts again, but it was a snap in Mavericks, and all of my preferences and messages are intact (since I didn't delete any of the other folders).
nothin7 & Brad Skidmore,
You guys Rock! That seemed to do the trick!
Step 1. In Systems Preferences > Internet Accounts, I deleted all the accounts.
Step 2. And instead of deleting the Accounts.plist, I instead used Text Edit to delete the everything that was between <dict> and </dict> that was repeating. After saving it, the file went down from 70mb to 350kb
Thanks So Much!!!!
Had the same problem since upgrade to Mavericks (100% CPU use perpetually). Tried most recommended solutions, including removing accounts under SysPrefs>Internet Accounts... Still no joy.
My Mail was NOT using a gmail account. However, I am using 3 POP accounts and 1 IMAP account. Approx. 20+gb of past emails/sent mail/etc. (I know, need to archive but have not found the best archive program yet that I feel comfortable with)
Spoke with AppleCare rep. She walked me through a very simple solution that seems to be working so far.
1. Open "Font Book" app
2. Click on "All Fonts" under collection
3. Select all the fonts that appear under that folder (Command + A)
4. Select File>Validate Fonts
5. Let the Font Validation run (for me took ~2min) - had approx. 500 fonts... However, there were ~50 fonts that did not pass the validation. For those fonts, I was instructed to remove (told that they were duplicates and causing havok in the Mail app). During removal, had to enter my admin password.
6. Restarted the computer - voila. All seems to be good in the hood again.
Mavericks: Mail uses 100% cpu
