Apple Mail consuming lots of CPU

Since I've upgraded my MacBook Pro from Snow Leopard (10.6.8) to Mountain Lion Apple Mail has been behaving strangely – Activity Monitor shows Mail consuming about 100% CPU for hours at a time. Mail is often very sluggish at displaying messages. I've rebuilt my mailboxes (Mailbox > Rebuild) but that doesn't seem to help.
Is anybody else experiencing this? Any ideas about how to troubleshoot/fix it?

Please follow these instructions to delete the Mail "sandbox" folder.
Back up all data.
Triple-click the line below to select it, then copy it to the Clipboard (command-C):
~/Library/Containers/com.apple.mail
Quit Mail.
In the Finder, select
Go ▹ Go to Folder
from the menu bar. Paste (command-V) into the box that opens, then press return. A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selected folder — not just its contents — to the Desktop. Leave the Finder window open for now.
Relaunch Mail and test. If the problem is resolved, you'll have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Post your results.
Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.

  • SQL Data Modeler on MAC consumes lots of CPU but still hangs

    Running data modeler version 3.1. on mac 10.7.3 - 64 bit both. Mac has got core i7 processor with 8Gigs or RAM, so no shortage of resources here.
    Got mail open as well as normal SQL Developer exploring the database tables and running queries. So plenty resources still available.
    I 'm experiencing intermittent conditions where I'm editing a card or entity properties and then developer goes into a "go very very very slow strike" mode. It consumes 99% CPU with average 40 threads running and approx 400 megs of memory consumed.
    It then takes for ages to respond to any inputs on the commit/cancel/apply buttons - more than 10 minutes! I once tried the "Force Quit" option - bad bad mistake. It lost all the task bar option - only had the "file" option on the task bar left!
    Anybody experienced the same or with a solution to this ?
    Andre

    Thanks for the help Ivan & Philip - made the change to 4GB RAM in the conf file but that did not solve the problem.
    Process
    1. Open view properties
    2. Click Test Query button - works fine
    3. Click Query button to edit query. Query builder never opens - monitor shows 100+ % CPU. Have to do force quit to close.
    Reverse - same thing
    1. Edit query 1st - no problem
    2. Test query - after db connection dialog - the test never execute. 100+% CPU again.
    I can edit as many view queries as I want and it works fine.
    or
    I can Test as many queries as I want - no problem
    When I try to do both on the SAME view - then I get trouble.
    Seems like an issue in the view edit dialog (only on Mac - never had the issue on a PC)
    FYI - I am on 64 bit Java.

  • Firewire audio consumes lots of CPU

    I have an external Edirol FA-66 firewire audio capture device. Plugging it in and switching it on sends kernel_task to 15-20% CPU usage immediately. That seems a bit excessive to me, can we expect the driver to be improved eventually?
    I tried to use the Edirol device as a second stereo output with DJ-1800, but the high CPU usage (and probably some other bugs in the driver and in DJ-1800) led to lots of audio dropouts and made it unusable.

    I too have a similar problem except I think mine is flash related. It's fine when just surfing and watching news/videos but when I play a flash game the hard drive starts spinning constantly and it takes minutes to switch applications or shut the game down. This usually happens at the beginning of a flash game, settles down for a while, and after 45-60 minutes it starts up again but the hard drive keeps spinning for another 15-30 minutes then settles down again for an even shorter amount of time and then repeats the cycle. It started doing this to me in firefox 6, but I've since upgraded to 7.0.1 and flash is up to date. I've run all the malware/virus checks, tested the drive, but can not find anything wrong. If I manage to get the resource monitor running, firefox plugin container usually is reading my pagefile.sys at 40-50 million bytes/min, plus a few more firefox entries running in the low millions/min. I know flash is a memory pig but I have 2 gig memory plus the virtual memory which I tried a couple of custom settings and then set back to default, with no change in performance

  • SQL QUERTY WITH TEXT 'SAVEPOINT FM_1' consumes lot of CPU

    WE ARE USING ORACLE DATABASE 10g Rel 1
    and Oracle Application server 10g
    WHEN WE check Top SQL the top most seql with Activity % and CPU % of
    45% is a SQL Which has following query
    'SAVEPOINT FM_1'
    What is this ?
    Chaand

    Hi,
    A savepoint is a point in a transaction when you set a "mark". Further ni the transation you can ROLLBACK TO a savepoint instead of rolling back to the transaction beginning. Look at this sample:
    TEST> CREATE TABLE A
      2  (
      3  I NUMBER
      4  );
    Table created.
    TEST> INSERT INTO A VALUES (1);
    1 row created.
    TEST> COMMIT;
    Commit complete.
    TEST> -- here it's a new transaction.
    TEST> INSERT INTO A VALUES (2);
    1 row created.
    TEST>-- here, i set a savepoint. Hence the table state is that it contains values (1,2).
    TEST> SAVEPOINT S1;
    Savepoint created.
    TEST> -- I add a new value which is in a diferent "transaction step/environment"
    TEST> INSERT INTO A VALUES (3);
    1 row created.
    TEST> -- And I get the 3 values as expected.
    TEST> SELECT * FROM A;
             I
             1
             2
             3
    TEST> -- Then when I rollback to the savepoint
    TEST> ROLLBACK TO S1;
    Rollback complete.
    TEST> -- And then commit
    TEST> COMMIT;
    Commit complete.
    TEST> -- The transaction part beween S1 and the ROLLBACK TO has "never existed"
    TEST> -- And as I have commited, the transaction part beween the begin of the transaction (first commit)
    TEST> -- and the savepoint is commited.
    TEST> -- Which we can see by:
    TEST> SELECT * FROM A;

  • Dwm.exe starts consuming lots of CPU when machine is idle

    Since doing a fresh install of Windows 8 Pro RTM x64 English on my Sony Vaio Z21 laptop, I've been bothered by a sudden increase in fan noise whenever I leave the machine idle for a while and the displays are turned off. Finally decided to try and get to
    the bottom of it today, so I ran the Performance Recorder with the CPU usage profile enabled and brought up the relevant graphs in Performance Analyzer. See the below screen shot for the results.
    I started the trace and then left the machine alone for a while to trigger the idle behavior. It's pretty clear that Dwm.exe is the main culprit. As to why this process would find anything useful to do when all the displays are turned off is beyond me. Also
    Outlook.exe sees a significant increase of CPU usage during the same time period. Whether these two are somehow related, I have no clue. Please note that I've disabled all other processes in the graph for clarity; no other processes showed any visible increase
    during the trace.
    Any advice would be greatly appreciated!
    Daniel Stolt, Perceptible, http://www.perceptible.net

    I'm seeing similar characteristics as some others in this thread:
    - The issue occurs when the system is idle AND the power management puts my displays on standby.
    - Modifying my power management settings so that the display is NEVER put on standby causes the issue to go away.  (The system will not show unusual CPU activity even after sitting idle for some time.)
    - When the issue occurs, dwm.exe shows some CPU activity.  dwm.exe's activity averages around 25%.  Several other applications show CPU activity as well.  Each individual application's activity averages less than 25% (so dwm.exe's activity
    is the most visible during this issue), but the total CPU activity adds up to around 60-75%.  The unusual CPU activity ceases when the monitor wakes up from standby.
    Do others participating in this thread observe that the issue goes away if they modify their power management settings so that their monitor is never allowed to go to standby?  I understand that this isn't a viable "solution" for most people,
    but I'd like to know if everyone else shares that same observation.
    I have a question (and appreciation!) for the persons genuinely contributing to this thread:  Do you see any unusual CPU activity occur in any other applications when this issue occurs?  For example, do you see a small amount of activity in explorer.exe?
    I ask this because I've watched the CPU graphs for several individual processes which happen to be running on my system.  (I've been leaving several process property windows open in Process Explorer to monitor individual process performance.  It's
    a kludgy method but it works.)  Processes such as skype.exe, steam.exe, procmon.exe (Process Monitor), and taskmgr.exe each nibble at the CPU when the problem occurs.  The effect is subtle but noticeable.  The CPU nibbling for these applications
    disappears when the monitor wakes-up from standby.
    I've also noticed that there is slightly less overall CPU consumption if all application windows are minimized when the issue occurs.  In the case of steam.exe, the unusual CPU consumption all but disappears when it is minimized.
    I believe Harri Kaimio's post has been the closest thing I've seen posted to a technical explanation for the issue.  It seems (?) that certain applications are attempting to draw something, but they are somehow blocked or otherwise unable to do so when
    the monitor is on standby.  dwm.exe plays a part in drawing, so it shows activity when this occurs.  However, instead of giving up, the applications seem to go nuts and attempt the (same?) thing frequently, thereby generating CPU activity.*
    *Please understand that these are guesses -- if someone can correct me with more technical details or procedures which would help disprove my guesses, please do show me where these guesses are wrong!  I'd love to work towards a solid explanation.
    A few more tidbits:
    - I do not run Logitech's SetPoint.exe.
    - I'm experiencing this on a desktop system.  My display adapters are:  AMD/Radeon HD 7800 series, and the integrated Intel HD Graphics 4000.
    - Running Windows 7.
    - I am incredibly pleased that not a single person has suggested "defragmenting" in this entire thread.  :)

  • Firfox consumes lots of CPU. Hard drive is always spinning and clicking w firefox. RUNS SLOW.

  • Huge problem using apple mail while sending email to a group...

    Hey - I am quite confused... apple mail has huge problems using groups with about 150 addresses when writing and sending an email... the writing of emails is nearly impossible. Once the group name is inserted in the addressline (address book in iCloud!), apple mail uses nearly 100% CPU and further writing is nearly impossible. When sending such an email, all addresses are suddenly visible - though the box is NOT checked and the addresses should be hidden... what can I do? I use this feature (sending mails to groups) on a daily basis and cannot accept visible addresses...
    Greetings and sorry for inconvenient english...
    Christof

    How about next time you send to the group, cc yourself, or include yourself in the group. Then receive the email on the iphone, you can "reply all" in order to send to the group. If you use an imap account, you can make a new folder, call it something like "groups", and save different group emails there for the next time you need to "reply all".

  • We love apple email, but it does not play wall with other venders when you want to use your own domain (lags, disconnections, etc.)?   What vendor should we use to make it push and work well?  We want to stay with Apple Mail.

    Help, our AppleMail does not play well with other Vendord to use our own domain.   iCloud mail works great, but so far others we have tried lag, disconnec, etc. not nearly as good as icloud mail.   Should we try exchange or office 365 plans with Apple Mail/  a lot more expensive?

    Microsoft Exchange is the best business solution, Office 365 will give a hosted version that works well, as you noted it is not the cheapest. You should also look at Zimbra, an excellent service.

  • Mail consumes a lot of resources making the os unusable

    I'm having a weird problem with Apple Mail: After launching, the program rapidly starts taking a lot of the system resources making it impossible to run any other program.
    CPU utilization is very high, the Mail process takes around 2.5 Gb of RAM (real memory) and over 20 Gb of virtual memory.
    The only thing Mail appears to be doing is updating it's cache.
    What could be wrong? Besides using another mail client, what are my options?
    Thanks.

    Hi eroussel,
    I'd suggest to try the following for starters:
    When launching Mail.app, try opening the mail activity monitor by going to Window --> Activity, or command-0. It should show you some detailed information on if anything is happening in the background in regards to talking to your mail server, smtp server, etc.
    As Linc Davis said, try booting in Safe Mode and see if the same thing happens.
    If the same thing happens in Safe Mode, try deleting the mail account (assuming you only have one) and re-create it again using the settings from your mail provider. Be sure to backup your computer first!!
    While doing all of this, leave the Activity monitor up from both Mail.app and the Mac OS X system Activity Monitor.

    Hi,
    >>A CHAR datatype and VARCHAR2 datatype are stored identically (eg: the word 'WORD' stored in a CHAR(4) and a varchar2(4) consume exactly the same amount of space on disk, both have leading byte counts).
    Ok, but on the other hands:
    SGMS@ORACLE10> create table x (name char(10), name2 varchar2(10));
    Table created.
    SGMS@ORACLE10> insert into  x values ('hello','hello');
    1 row created.
    SGMS@ORACLE10> commit;
    Commit complete.
    SGMS@ORACLE10> select vsize(name),vsize(name2) from x;
    VSIZE(NAME) VSIZE(NAME2)
             10            5
    SGMS@ORACLE10> select dump(name),dump(name2) from x;
    DUMP(NAME)                                         DUMP(NAME2)

  • EA1 - consumes a lot of CPU

    New 2.1.0.62 EA1 consumes a lot of CPU on my Macbook with MacOS 10.6.1.
    After I have opened two database connections (Oracle) everything seems to be fine (CPU usage 2% and below), but after I have executed some sql statements I will never get below 7% of CPU usage. It gets even worse the longer you work with SQL Developer (> 25 %).
    The statements I have executed did not have many rows (< 100) and do not take long (< 1 s).
    Regards,
    Sven

    Hi Barry,
    sorry haven't seen that you have edited this thread. Yes, for me it is still the case. I just updated to 2.1 final release and am testing. I am using SQL developer for 40 minutes now and it is consuming 24-25% of the CPU(s). ... after 2 hours of work it is at 35-36%.
    Is there any tool that I can use to track this issue down or any information that I can send you? The suggested "topthreads" does not work here :-(
    Regards,
    Sven

  • Apple Mail client app (version 8.0) using 100%+ of 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.

  • Changed email from pop to imap in entourage 2008 and apple mail and have lost a lot of messages

    Changed email from pop to imap in entourage 2008 and apple mail and have lost a lot of messages. I am a rookie and don't know what to do to correct the situation

    I found this great set of mail AppleScripts:
    http://homepage.mac.com/aamann/Mail_Scripts.html
    It includes one script to delete duplicate messages. So if we can't find a way to do this right, then I'll just download all the duplicates then delete them. Of course I don't want to actually do that, lets call this the nuclear option.
    So can anyone think of a way to make an IMAP account for my gmail without it downloading all the messages again that I have already downloaded?
