Mail gobbling up CPU: 120%
Hi,
Since upgrading to Mevericks my MacBook has been running super hot.
When I check the Activity Monitor, I find that MAIL is gobbling up CPU... sometimes in excess of 120%.
When I sign out of Mail, the MacBook cools.
Anything I can do to get Mail back to a more normal CPU usage? Never had this problem before.
Thanks!
Cat
Thanks. Appreciated.
Will tackle on my next day off!!!

<Edited By Host>Back up all data.
Select all your mailboxes, and then select
Mailbox ▹ Export Mailbox...
from the Mail menu bar. Export the mailboxes to the Desktop folder.
Make a note of the settings for all your Mail accounts – everything you'd need to reconstruct the settings from scratch.
Quit Mail. Then select
▹ Force Quit...
from the menu bar. A small window will open with a list of running applications. Mail may appear in that list, even though you quit it. If so, select it and press return. Close the window.
In the Finder, hold down the option key and select
Go ▹ Library
from the menu bar. Move the following items from the folder that opens to the Trash (some may not exist):
Caches/com.apple.mail
Saved Application State/com.apple.mail.savedState
Leave the Finder window open for now.
Relaunch Mail and test. If the problem is solved, you’re done. Delete the exported mailboxes. Otherwise, quit Mail and move these items, if they exist, from the open Library folder to the Desktop:
Application Support/AddressBook/MailRecents-v4.abcdmr
Containers/com.apple.mail
Mail
Preferences/com.apple.mail.plist (OS X 10.7 only)
Preferences/com.apple.mail.searchhistory.plist (OS X 10.7 only)
Note: you are not moving the Mail application. You’re moving a folder named “Mail.”
Log out and log back in. Launch Mail. It will behave as if you were setting it up for the first time. Go through the setup process with one of your accounts, using the information you noted earlier. Test. Same problem?
If there’s no improvement, quit Mail again and put back the items you moved to the Desktop, replacing any newer ones that may have been created in their place. You don’t need to replace the items you moved to the Trash.
If the issue is resolved, recreate the rest of your Mail settings, then import the mailboxes you exported:
File ▹ Import Mailbox...
After importing, test. If Mail is still working, delete the items on the Desktop and close the Finder window. -
Mail gobbling memory, activity stalled
Hi,
I'm having a recurring problem of mail gobbling up large amounts of memory e.g. 2 GB real memory in the activity monitor. When it reaches that point everything else slows to molasses and I have to force-quit mail and restart it. In the activity window it seems to stall on "adding: 'some-subject-line-here'" activities.
I've tried resetting the sync history as described here in an apple thread: http://tinyurl.com/ybwrxn4. That seems to work (sometimes) for a short time (up to several days) then the same problem starts again.
I (unfortunately) have IMAP mail. I have about 20 each of smart mail folders and IMAP folders. The IMAP folders are especially annoying because they take so long to update. But, I am told not to keep too many messages in the main IMAP inbox.
In general, IMAP engages in continuous chatter; the activity window nearly always shows "adding", "caching", "adding", "synchronizing", "communicating", etc.
thanks for any suggestions.
-sarahDeleting items from the "bundles" folder according to this tip seems to work. Mine had MailTags (which I wasn't using much), mail act-On (which I do use- I'll reinstall it), and a growl piece.

Mail uses more than 120'% CPU when fetching headers
Hello,
mail uses more than 100% CPU and the system response gets slow, affecting the other processes when mail starts, and the mail activity viewer says: fetching headers.
It happens when I check my mail with mail client directly in the same server, or when I connect from another machine, my mail Version 2.1 (752/752.2), I have 3 IMAP accounts.
I have verified and repaired the disk (no errors), I have set up mail from scratch, the first network connection is ethernet,
I am using mail program on the server trying to check the mail in the same server. when I open the program, and it starts to fetch headers, the 100 % percent or more of CPU is used (128%,etc).
when I try to conect from another mail program to this server the 100% cpu or more is get when fetching headers (I am using a firewire connection, and the another machine is a MAC PRO (4 processors, 2 x 2.66 GhZ Dual Core Intel Xeon, 1GB ram 667 mhz DDR2 fB/Dimm, MAC OSX 10.4.9, with no other programs running), so the problem is on the server.
I have booted the machine in safe mode (the red text "safe mode" appeared), and the same things happened, I have some screen shots available
from the mail forum they told me that I should check this problem in the server forum.
http://discussions.apple.com/thread.jspa?threadID=957222&tstart=0
any idea?
thanks

Thank you for the suggestion. I will try that soon. My macbook meets well over the hardware requirements for that package. Also only the cpu usage is high, i have 4GB ram and only 500-700 MB of that gets used by adobe premiere.
I have have run the hardware test in a loop and it passed everytime, so i dont doubt the hardware.

Mail uses 100% CPU, then says there are 0 messages in mailboxes
Hi all,
I just decided to switch from thunderbird back to mail for various reasons. So I imported all my t-bird mail boxes successfully by copying the mailboxes and adding the .mbox extension, as suggested by someone somewhere on the internet. Mail says I have alot of mesages in some of the mailboxes, it says 14,000 in one, but I I don't think thats right.
At any rate, here's the problem: When I click on a mailbox I get an icon next to the mailbox that looks like a pie chart, initially messages in the mailbox will be displayed. If I click on another mailbox, eventually (after a mailbox or 2) I get the pie icon next to that mailbox and no messages displayed, and the title bar of the mail window now reads *name of mailbox* 0 messages, now if I click back on any other mailboxes I get the pie and no messages displayed and the 0 messages title bar, if I click on my inbox the title bar says also says 0 messages, 11 (or whatever) unread.
If I quit mail mds and mdimport are going crazy for a little while probably trying to index the messages. If I then reopen mail it displays as it should for a few clicks then I start getting the pies and no messages displayed.
Note mail is maxing out the available CPU cycles through this entire process.
So I guess I don't really know what the deal is. Do any of you? Like, Will mail sort itself out eventually? Do I need to re-import? Can mail even deal with the amount of email messages I have? Can I turn of spotlight indexing in certain mailboxes?
I thought I liked the idea of spotlight integration but maybe I don't...
TIA,
Jonathan

Mail uses 100% CPU--Must "Force Quit" to kill it
When I start up Mail, it works fine. I scroll through a few messages, Mail is responsive.
Then, at some point, I try to read an email, and Mail says "Loading Message" for 5-30 seconds before displaying the email. It's not the same message every time, and it's not a message with an attachment. Oftentimes, it's a short email.
Once Mail has displayed "Loading Message" for the first time, the CPU usage goes to 100% and stays there, even after it finally displays the email. Then, Mail will show the "Loading Message" for every mail I try to read, and the only way to kill the Mail program at that point is to "Force Quit".
Needless to say, this makes Mail unusable.
I'm a new Mail user, so my Inbox had less than 100 messages when this problem first started happening. (I didn't try to import old email.)
I get my mail from a POP server (gmail), so it's not an IMAP problem.
I'm Running:
Mail 2.0.8 (749.3)

Mail using 100% CPU?
My fan kicked on about 10 minutes ago for no apparent reason, and activity monitor showed that mail.app was maxing out my CPU. I quit mail for about 20 minutes, and upon starting it back up, mail immediately maxed out the processor again. Does anyone have any idea why this could be?
MarkMy Mail jumps up the CPU to 100% for each character I type. 10.5.2 MBP 2.33GHz.
I use a large signature when ever I reply to one of my vacation rentals. It has about 4 small paragraphs, about nine links, 2 phone numbers, and 3 references to dates. This just started to happen when I upgraded to Leopard. I hit New EMail, put in the above signature text, and typing screeches to a halt. Each character takes about 1-2 seconds, Mail CPU maxes to 100%... I stop typing and it goes back down to normal, type 1 character and it jumps back up. When I copy and paste a sentence of text, it can take up to 20-30 seconds.
I tried /usr/bin/sqlite3 ~/Library/Mail/'Envelope Index' vacuum and it shaved my index from 38 meg to 36 meg but didn't do anything.
I have a feeling it's related to Data Pickers. Anyway to turn that off so I can test it. Or does anyone else have any other suggestions?
Thanks -
Mavericks: Mail uses 100% cpu
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?
Deleting the envelope index files and reindexing the messages did not help in my case. 6 hours later, CPU usage by Mail is still at 100% - independently of whether there is a network connection or not. With network connection the activity window provides no indication that Gmail/IMAP folders are repeatedly synchronized. There is also no indication that spotlight is updating index files, as md* processes are close to 0 % CPU usage.
Sampling the Mail process for 3 seconds with 1 millisecond of run time between samples (1984 samples in total), shows where the time is used:
1984 RunCurrentEventLoopInMode (in HIToolbox) + 226 [0x7fff8c04af0d]

I'm afraid there is no other option than hoping for further bugfixes from Apple...
It is a great shame that Apple's quality control did not discover the severe errors in an application that is so important for many customers. Did Apple's business administration, while pushing for quick solutions, prevail against engineers? Well-known high-tech companies have perished from this (epidemic) disease. -
CPU 120 mm fan and interchange connectors
my akasa heat sink fan has a three pin fan but my motherboard has four pin does any one know where i can get four pin female to three pin male molex connectors.i have tried ebay but no luck at all many thanks
my pc
msi P6N sli platinum
Q6600 quad
msi 258 mb graphic card pci express
3 GB crucial ram
420 be quite PSUjack and jason thanks a million for both suggestion but listen to this by accident i connected a 120 system fan to one of the system fan connectors and noticed that it is much quieter than cpu fan so i removed the 120 mm cpu fan and replaced it with 120 system fan . it does about 1200 rpm i can not adjust the speed but it is much quieter than the cpu fan which easily does 2200. this is not perfect but it does the job for the time being (system fan have much large internal resistors and that is why they are slower than cpu). my akasa heat sink fan is great but currently i have not seen four pin 120 cpu fan??? many thanks for your great help

Yosemite Mail.app High CPU Use
Since upgrading to Yosemite, Mail.app frequently spikes multiple cores for an extended period of time. Even background mail checking spikes the CPU load.
Seeing the same issue. The problem, in particular, relates to email sent to me from another Apple Mail user via Exchange. I can view the email on my iPhone or iPad, but not in Apple Mail.
I think, from what I can see in the crash logs, it relates to parsing attachments. (which may just be things like email sig blocks)

Osx 10.9 Mail & Safari High cpu load
Hello,
A few weeks ago I updated to OSX 10.9. After working a few days with it, I run into several high CPU load issues.
2 processes: mail-webmateriaal and safari-webmateriaal (dutch).
Now I use Chrome instead of Safari which solves 50% of my problem, but it is not so easy to change to another mail-client...
Does anyone have a clue about the possible cause, but even more important, a solution?
Best regards,
Johanjvdstoel,
Ditto. I have the exact same OS 10.9 issue on a Late 2008 iMac with a 3.06 GHz Intel Core 2 Duo that is maxed out at 4 GB RAM (seemed like a lot of RAM at the time).
Mail, Safari, and Firefox--but not Chrome--whether running any 1, 2, or all 3 programs together keeps the CPU running hard at and often above 100%. This occurs even when the programs a sitting idle from the user's perspective. Disabling all extensions on Safari and Firefox did not help. Nor did running Onyx to clear all catches system wide.
Calling on anyone with a virtual PhD in Maverics (or real Apple OS 10.9 street-smarts) for suggestions.
Best,
Pete -
Fan noise after OSX update - Mail above 100% CPU
Hi,
I just updated to the latest 10.8.4 version and suddenly Apple Mail is running at 75% till over 100% CPU consumption making the fan running constantly. There is no active usage of Mail, no loading of heavy emails or anything. This problem with Mail never occurred before and it happened directly after the update so there might be a relation. The fan noise stops as soon as I quit Mail.
What could be the reason?
Thanks in advance,
EricHey,
problem is solved: I deactivated and again activated my mail accounts by clicking the check boxes in Mail´s preferences menu. Immediately the CPU consumption fell to normal and so did the fan.
Cheers,
Eric -
Mail uses 100% CPU...
Hi everyone,
My Mail is very annoying since a few months... One in a while (almost every week), the app will start using a lot of CPU. Force Quit is required. When I restart Mail, it barely have time to begin cheking my new mails before jumping on the CPU again.
To solve the problem, I copy over the last version of my prefenreces from Time Machine. Is there a permanent solution to this bug?
BTW, I have 3 IMAP accounts (one is gmail) and 1 POP.

Hi,

Summary:
Mail.app become unresponsive and use over 100% of CPU when i'm behind a corporate proxy that restrict access to IMAP protocol.
Steps to Reproduce:
connect the network and configure the proxy.
Open Mail.App
Mail.App use more than 100% of CPU
Expected Results:
have small cpu usage
Actual Results:
use high cpu
Regression:
Need to disable all IMAP account to use mail.app have good performance of my computer
Notes:
I've tried AutoProxy and Manual proxy. I've also tried at home to restrict access to IMAP on a NATed network. The CPU usage was about 0,01%.
iCal have a similar problem with caldav account behind the same proxy. The computer came very hot because is using 5 to 10% cpu all the time. I need to disable all caldav/iCloud in iCal to be able to use it while behind the proxy.
I have a Exchange 2010 account configured in Mail/iCal/Addressbook
Thank you
