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?

My 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

Mountain Lion: Mail uses 100% cpu

Since the update to Mountain Lion Mail uses always more than 80% of cpu as long as it is running. Has anyone a solution?

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)
Mac OS X 10.4.5 on a MacBook Pro
Has anyone else experienced problems like this? Any suggestions?
MacBook Pro Mac OS X (10.4.5)

I'm having exactly the same problem with Mail 2.1.1 (build 752.3).
I'm experiencing this since I configured a Gmail account and read the messages in a Smart Mailbox.
There are 3 rules:
All messages where one of the destinations is <my email>
All messages where the origin is <my email>
All messages in malbox <my Gmail inbox>
Include replies: checked
I'm able to use (send/receive) this smart mailbox for several hours without any problem, then when I send a message (random length, no particular difference with the other sent messages), Mail complains about my reply (that I'm supposed to see in my smart mailbox) not being on the server (?), and all mailboxes (including trashed, spam, smart and non smart) are displaying "0 messages".
I'm still able to receive mail, and the unread counter grows as I receive them, but I'm not able to see any message in the box.

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:

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.

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...

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.
Thanks!

Apple Mail client (version 8.0) using 100%+ CPU upon using mail drop (13" R-MBP running Yosemite 10.10)

Hello Support Community,
I am having quite the interesting issue. I have read plenty of reports where users' Apple Mail app is using 100% of CPU. This did not start for me until I went to go use the new mail drop feature in Yosemite. I am running Yosemite (10.10) on my 13" Retina - MacBook Pro (flash storage, 8GB RAM, 2.4 dual-core Intel i5) and my Apple mail is version 8.0. I have tried 3 different mail services (2 gmail accounts and iCloud), all result in the same issue. I have also done a complete erase of the hard disk and a brand new install of Yosemite, the issue persists.
As previously stated my mail app is using 100% upon, and only while, using the mail drop feature. If I force quit the mail app and allow it a minute, the mail app returns to using less than 1% of the CPU and the app and entire system resume normal function. Upon attempting to resend the same message that is placed in my outbox the CPU usage jumps to 50-80%. After a few seconds, the CPU usage will sometimes jump higher than 100%, ranging from 130% - 199%. All of these observations were made using Activity Monitor. Of course you can see my frustration, an app using this much CPU stops every process my Mac is doing (using safari, messages, iTunes etc.) - the whole computer locks up. Even force quitting is a difficult process to attempt.
Does anyone have a fix for this? I am at a loss and have no idea what to do. I am a pretty tech savvy guy and have tried everything that I would've thought would fix this. Is there anyway this could be a hardware issue? I don't think so but... all possibilities need to be taken into consideration, even though that one seems outlandish. Upon creating a new user account with a separate user library (but same system library) I figured the OS was the problem. I can't narrow it down to being a specific mail provider, and it can't be my OS since I have now erased and reinstalled 10.10 twice. Thank you!

I have this same issue. It has been driving me insane, Mac Mail uses 100% CPU most of the time I use it, after every time I open the machine, or after a sleep or even mostly after a screen saver has locked me out. It normally settles down after 5-15 minutes, but then happens every time again. It is killing my battery.

Mail is using 100% CPU processes - wondering if I possibly have the answer?

Hi...
I have a big problem with Mail using all the CPU processes but may just have found a possible solution. I'm posting to see if anyone else shares this problem or can shed some light on whether or not this is a possible solution.
_*The Problem*_
Over the past couple of weeks, I've noticed that Mail is using on average 100% of the processes and sometimes up to 168% (I have screenshots to prove it). My 17" MacBookPro gets very, very hot and the fans spin up to cool it down so it's obviously not right as it's never done this before. I can only use Mail intermittently now as the machine overheats quickly soon after Mail starts up. As a result, the CPU is being hammered so I can't now use Mail or other CPU intensive applications properly, which is a big problem.
I've used the iStatPro widget to verify that Mail is constantly using 100% of the CPU processes. I've also verified this using Utilities / Activity Monitor. When the Activity Monitor application loads, I've selected Mail from the list of Process Names and then clicked Inspect. I've managed to identify the parent process as being launchd (110) which is using all the CPU power. Here are some other stats for this parent process:
%CPU 95.56 (at that specific instance)
Threads 15
Ports 275
CPU Time 3:30.55
Context Switches 310968
Faults 65795
Page Ins 1
Mach Messages In 272627
Mach Messages Out 65025
Mach System Calls 1459878
Unix System Calls 103120
I guess the important bit is the first bit that says 95.56%.
I have screenshots to back this up but no way of posting them here. I have also managed to use Activity Monitor to generate sample data that the process is creating and again there is no way of posting an attachment here but there is lots of sample data from the process to look at. I've compared the sample data from my MacBookPro to a colleagues machine and the difference between the sample data is enormous. There is obviously something very wrong happening.
Here's some basic info about my machine, with the serial number removed:

_*The Possible Solution??*_
I recently installed a Beta version of Daylite 3 as I was interested in the application and remembered that it integrates closely with Mail. I wondered if Daylite was constantly trying to communicate with Mail and having problems. Having uninstalled Daylite 3, the problem of Mail using all the processes has so far not reappeared. Mail is now using very little of the CPU processes as is usual. However, I'm currently at home instead of on my network at the office so I'll wait to see if the problem still fails to appear when at work.
I know other people have had problems with Mail using 100% of the processes. Have you also installed Daylite 3? There has been some talk of Flip4Mac being a possible culprit but I use Flip4Mac and haven't previously had the problem. The only recent change and connection I can think of is an install of Daylite 3.
I don't want to talk down Daylite 3 but it's the only thing I can think of and having uninstalled it, the problem hasn't occurred. I hope I have stumbled across the solution but any thoughts, shared experiences or feedback would be greatly appreciated...
Many Thanks,
Nigel

Hi...
Thanks for the post. Not sure what you mean when you say "What does Mail say it's doing?" Can you be more specific and supply specific instructions to follow so that I can give you the information you need?
I've sampled the process but can't post any attachments on the forum. I've listed what the Activity Monitor stats are saying at the top level in the post above.
This is a serious problem that's hammering my machine and making it overheat and almost making it unusable. Any feedback or instructions anyone can give me for what info to supply to help you determine what the issue is would be greatly appreciated. I'm hoping to find a solution here rather than have the machine overheat permanently and eventually fail, leaving me to sort it out with AppleCare.
Help!

All programs using 100% CPU, freezing, crashing, -10810, -600, and -1712 errors

Okay, so. I have a Macbook Pro from December 2012, a little over a year old.
Version 10.9.1, running Mavericks
Processor 2.4 GHz Intel Core i7
Memory 8 GB
Startup Disk - Macintosh HD
I can send more info if I need to. I'm a graphic designer using Photoshop, Illustrator, and InDesign usually simultaneously, as well as Spotify, Messages, Sparrow (mail), Stickies, Tweetdeck, and Evernote. I also use a wireless mouse, drawing tablet, and second screen. This has never been a problem (I mean, my old computer had 4 GB memory and handled these programs just fine, except for Final Cut Pro 7) up until recently.
For the last two months, my computer has been seriously out of whack.
I'm constantly having to refresh finder
Every time I open Google Chrome, all of my extentions crash immediately and any website I try to go to is extremely sluggish (but Safari works)
The dock freezes
Constant error messages: 1712, 10810, 600
Audio fails randomly
Overall, the problem seems to be that I can't do more than one thing at a time -- I can't take a screenshot if more than two programs are open, I can't open DMG files, I can't open Spotify if any Creative Suite program is open. I've been watching the activity monitor, and it seems like each program is trying to use 100% CPU, which doesn't seem right. I have to close every program to work in Photoshop, which makes me miss calls and emails.
I've tried restarting in safe mode, verifiyng the disk and repairing permissions, I used time capsule to restore to a time before it was happening, and restored my user profile in Chrome. I'm at my complete wit's end trying to figure this out! I feel like my next step is to just reinstall my OS completely, but that would be a major setback for getting my work done, and I'm not even sure that would work.
I've looked on other forums and it seems like the Mail app typically causes problems, but I don't even use it, I use Sparrow.
PLEASE PLEASE PLEASE HELP

Launch error -10810 in Mavericks
I have the same issue since a couple of days. Nothing that I found in the community (rebuilding launch info using Onyx or manually deleting the apple.com-launch prefs) has helped me so far. Only some apps are affected (PasswordWallet 4.7.4 among them).
I can launch it once and it will run fine as long as it’s open. Next time it refuses to open displaying the error -10810 message instead. I trash the app and use a fresh one off the vendor’s dmg file I downloaded and the sequence repeats.

Thunderbird using 100% CPU?

I have Thunderbird 3.1.10 on a Macbook usng OSX Lion and Thunderbird has started using 100% CPU and causing the fan to run and tax the overall system. Unfortunately I use Mail for my stuff and Thunderbird is used for all my wife's e-mail so we can't really migrate over to Mail. Anyone run in to this before and find a succesful solution?
thx

Do you use McAFee ?
* see info: https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues
Do you have large files?
If yes, consider organising mail into suitable folders and Archiving older emails.

If you have an IMAP gmail account, do you see the 'All Mail' folder?
If yes, this is gmails archive of all of your emails, so it is only doubling all the emails and disc space. It is advised that you unsubscribe from seeing this folder.

Discoveryd process uses 100% CPU - Safari Can't find the server

Hello
Since upgrading to Yosemite, I lose connection to the internet 2 or 3 times a day. (Outlook goes offline at the same time)
This is with a wired connection. (Wi-Fi is turned off)
Safari gives me the "Safari Can't Find the Server" message.
Restarting the computer solves the issue temporarily.
While I'm unable to connect to the internet, Activity Monitor shows a process named "discoveryd" that uses 100% CPU.
Force quitting this process gives me back access to the internet instantly. Unfortunately, I suffered a kernel panic (auto restart) a few minutes after force quitting discoveryd. I'm not 100% sure those 2 are related but it would be an odd coincidence as I never experienced had a single kernel on that system. Haven't tried force quitting that process since.
I'm using this iMac in a work environment. (Connected to a windows file server and exchange)
This issue has been happening 2-3 times a day since the day I upgraded to Yosemite.
Any pointers on what could fix this issue ?
Thanks

Finder and loginwindow use 100% cpu with 10.6.8

I recently installed the patch to OS X 10.6.8 and now the finder is very unstable and uses 100% cpu and the loginwindow uses 100% cpu also. Yes I have Parallels 6 on this machine but I already "un-checked" the "show windows applications in doc" option which is the recommended solution. However, this did not fix the problem. I do not know how to determine what actual process is causing this finder / loginwindow issue. I very much appreciate if anyone has suggestion how to fix this problem.
This is on a mid-2011 MacBookPro.
thank you.

TBauer, I had the same problem with 10.6.8 using 100% of the CPU with Parallels 6 installed. The following steps solved this problem for me:
0. Take a screen shot of your Dock if you wish to remember it as currently set
1. Launch Activity Monitor and click on the CPU column so you can see Dock using the CPU
2. Move ///Users/ ... /Library/Preferences/com.apple.dock.plist to the trash
3. Click on Dock and click on Quit Process to stop the Dock
OS X will then rebuild the default Dock
4. Put the items back in the Dock that you want
That solved the problem for me yesterday morning. I've launched Parallels 6 several times now and moved the machine from my work network to home and the 100% CPU problem hasn't returned.
Hope that works for you, too!
I don't think using the combo updater will solve the problem. The problem appears to be a .plist that is generated with OS X 10.6.7 and earlier that contains icons of a larger than Apple documented size causes the CPU looping. Rebuilding the dock.plist under OS X 10.6.8 appears to solve the problem.
Parallels has issued a knowledge bulletin saying they are looking into the problem. On their web site they have another approach involving moving the offending icon out of the dock to solve the problem. I like my solution better but theirs works, too.

ITunes will uses 100% cpu and will not close in OSX Lion

When I start up iTunes, after a few minutes, the fan kicks on and Activity Monitor shows that it is using 100% CPU. The fan kicks up and the MBP gets warm. I have to force close to get it to shut down. iTunes match is constantly running, so maybe that has something to do with it?
I'm not running it in Mini Player mode or anything like that, so I'm not sure what's causing the problem. Any thoughts on how to diagnose it?

I also have this problem which has been getting worse with recent successive updates of Firefox. As a long-time user and advocate, I am about ready to look for an alternative browser. Firefox will not close and exit properly, requiring direct cancellation through Task Manager; starts up very slowly (often 1 to 2 minutes); and frequently locks up the CPU with 100% of cycles while doing NOTHING; offers to restart crashed sessions, but cannot recover and reload those sessions; will not operate correctly while any other application accesses the internet, like uTorrent. Firefox is set to delete cookies, etc. whenever the session closes, sqlite database is vacuumed regularly, CCleaner regularly wipes remaining accretions, and disk is defragged. Currently running 3.5.5 but will NOT upgrade until this problem is solved since later builds report the same problems. I know several other users who have experienced the same problem and I can no longer automatically recommend Firefox to users and clients. Is anybody paying any attention to this problem? What is being done to address this fault? Why is there no response to the original poster? Is this really a support forum or just a way to preoccupy and distract the users who suffer this malfunction? Wireless 54Mbps connection. No Adobe Flash, QuickTime, MS Silverlight, etc. installed on this machine. Firefox 3.5.5 with the following add-ons:
Aardvark 3.0
Adblock Plus 1.2.1
Adblock Plus: Element Hiding Helper 1.0.6
Free Download Manager plugin 1.3.4
Highlighter 0.1.4
MR Tech Toolkit 6.0.4
repagination 2006.4.5.1
Save Complete 1.0.1
Session Manager 0.6.8.3
Tab Mix Plus 0.3.8.4
Unhide Passwords 1.2.5.1
User Agent Switcher 0.7.2
Thanks for any help or suggestions.

New DVD writer on Satellite M40-193 uses 100% CPU

Hello anyone,
recently I have replaced my DVD-writer with a new one. My laptop is a Satellite M40-193 (PSM40E-06M026IT) and the original drive is a Mat****a UJ-831B. I have replaced it with a Sony-Nec Optiarc AD-7633A because I like the slot-in feature and the Labelflash feature.
Unfortunately it makes me a problem. It will use 100% CPU every time I use it. I cannot figure out the problem. Is there anyone who can help me? It is a software problem or hardware?
Thank you.

After six days this is the only help I can get on this forum: "...this optical disc drive is compatible with your notebook model?".
The ATA communication bus is a standard.
The exsistence of a compatibility list does not means that ONLY those drives present in the list can work with the relative notebook.
Those drives are the ones tested and the ones that Toshiba says: "this drive surelly work" but not says "this is the only drive that work".
In fact I have RESOLVED the question with a little software I have found on another forum and now my drive works perfectly and I have a newer and more featured drive than those in the list.
Thank you Mike

Oracle uses 100% CPU

Hi,
I have installed Oracle 10g R2 on 64bit linux. It was working fine, until last week. I got alert that oracle uses 100% CPU.

When I log in to EM, I can see section
Host CPU
It is 100%.
I have only instance named "parama". and it uses 1% CPU ant the picture shows that 99% CPU is used By Other.
What is Other? Why does it use that much CPU?
I had another oracle instance few months ago, but I is not used now (it is not even started).
How do I restore normal system performance?
Can I kill these processes?

Hello,
I have a similar problem. I see 2 perl processes related to Oracle that are taking up 99% of 2 cpus. These 2 perl processes have been running for days and keeping the load average high (above 2) on a mostly idle system.
The 2 perl processes are running:
/oracle/app/product/10.2.0/db_1/perl/bin/perl /oracle/app/product/10.2.0/db_1/sysman/admin/scripts/db/dbarchfull.pl
and
/oracle/app/product/10.2.0/db_1/perl/bin/perl /oracle/app/product/10.2.0/db_1/sysman/admin/scripts/db/dbresp.pl
Has anyone seen this problem? Can I kill the perl processes?
