Mail running slow with Mountain Lion

It seems that the Mail application has slowed significantly since upgrading to Mountain Lion with frequent lags when attempting to swith email accounts.  My iMac also is very slow to respond after being idle for a significant period.  Are others experiencing these issues with the new OS?

  • Did macbook air mid 2009 running slow with mountain lion?

    did macbook air mid 2009 running slow with mountain lion?

    Yours is the first computer I've heard about on these forums that is attempting to run Mavericks with only 2GB of RAM.
    Indeed that is acceptable per the Mavericks requirements:
    http://support.apple.com/kb/HT5842
    ... but as you may know, Apple has not sold computers with as little as 2GB RAM for quite a while.
    I suggest therefore you make sure you remove any applications that may be overtaxing your machine.  Examples are browsers other than Safari, Mac cleaning products (such as Mac Keeper), or any other non-Apple app that has some startup process running (such as Outlook).

  • Why is my macbook pro running slow with mountain lion?

    After installing Mountain Lion, I find navigating, opening programs, etc. is taking more time, why is this?

    Immediately after installing Mountain Lion, your system will be rebuilding the Spotlight index. This should only take a couple of hours at most. If the problem persists you can run diagnostics. I just happen to have written a little diagnostic program recently. Download EtreCheck from http://www.etresoft.com/download/EtreCheck.zip, run it, and paste the results here.

  • Internet speed is slow with Mountain Lion 10.8.2

    Internet speed is slow with Mountain Lion 10.8.2, but booting in separate drive running 10.6 is fine. Tried renewing DHCP, zapped the PRAM, ran disk utilities, and sudo chron.  No change. I am running 2008 Mac Pro, 8 gig ram, AT&T DSL via ethernet. Getting 0.15Mbps instead of 3Mbps.

    Did you try creating a new location and deleting the old one? Just renewing the DCHP on its own may not be enough. Follow all the instructions here, first:

  • HT1338 i cannot run java with mountain lion

    i cannot run java with mountain lion

    @jnsmth
    I see Barney-15E made suggestions regarding Chrome preferences. There's also a setting on the Mac to deal with this. Regarding the drop-down menus not seeming to scroll through (such as a list of states)--where when you place or click your cursor over the drop-down menu and it only opens to some of the options in a list, I found that you have to change the scroll bar behavior in your computer's (and not the browser's) General Preferences within your System Preferences.
    Open System Preferences, and click on "General" inside the top row of "Personal Preferences" (as it is in my system with Mountain Lion, and I think prior operating systems before that).
    Once inside General Preferences, select the radio button option for your scroll bar which you'd like to use in the "Show scroll bar:" section ("Automatically based on mouse or trackpad," "When scrolling," or "Always." If you're using a mouse and not a trackpad, you'd probably want to select "Always" as it takes swiping over the drop-down list on the trackpad to enable (make visible) the scroll bar and/or scroll the list.
    Either with the installation of Mountain Lion, or the installation of my trackpad (I'm using a desktop iMac and not a Macbook / laptop) I found that the righthand scroll bars seem to automatically disappear. When I moused over or clicked on a drop-down menu (such as the list of states) I'd see only the first few options in the list. In order to access the rest of the states (get the list to scroll) you have to either have the scroll bar setting set to show "Always" or (if you have a trackpad) use the trackpad to swipe/scroll while hovering your cursor over the list's items to get it to scroll the list, and thus then show/reveal the lefthand scroll bar (which can then be accessed with your mouse if you prefer.
    This confused me at first when my scroll bars seemed to disappear, but was an easy fix.
    Hope that helps with that part of your issue.

  • Any settings that can be adjusted to make everything run faster with Mountain Lion

    Hello,
    Does anyone know of any settings or adjustments that can be tweeked to make my machine run faster with Mountain Lion?
    Thanks, Jason

    yes you can do it yourself - it's actually a simple upgrade - i use a ssd in my macbook and have the RAM maxed out to 16GB.
    as for what brands should you consider, here are some good ones.
    Sandisk Extreme - Currently the fastest one out there.
    Kingston HyperX - Second fastest - this is what I have in my 13 Inch Late 2011.
    Samsung 830 series - Fast and uses less battery power - this is what's installed in the Macbook Retina.
    Crucial M4 - Also a fast SSD - I have the 512GB installed in my 15 inch Late 2011.
    If you decide to install one of these ssd in your Macbook - let me know if you need a step by step on how to clone your drive.
    Good luck..

  • Time machine very slow with mountain lion

    Time Machine backups seem very slow with Mountain Lion.

    Same problem here. I just upgraded from Lion to Mountain Lion. I only got 19 GB of space, but Time Machine wants 10 hours, whereas in OSX Lion a full backup would take just under an hour, and incremental updates were lightning fast.
    I even sat it up to do it overnight, but on 8 hours it was only half way through only 10 GB. I can't live with that in the future.
    Im trying to backup on a SD card which seems to work very good in Lion. Im on a 2012 Macbook Air using a SSD.
    My bite of the apple has been somewhat sour. I tried reformatting the SD card, well knowing that I would lose old backups. But still the backup is extremely slow. Now I can't install Lion or Mountain Lion from scratch without having to wait 10 hours for TM backup or installing tons of applications and settings again. Bummer. I'm never going to early adobt a OSX upgrade again.

  • HT4848 Two days ago I upgraded my MAC PRO from Lion to Mountain Lion via my account at the Apple App store.  My machine runs so slow with Mountain Lion especially mail that it is completely useless.  It take about ten minutes per mouse click to register. 

    I also run Parralles 7.  I re-installed this a few times with no affect.  I have it not running and my Mountain Lion is still too slow to use.  Again a single mouse or keystroke takes up to ten minues to register. 
    Suggestions ?

    Startup in Safe mode (holding Shift key down) http://support.apple.com/kb/HT1455
    Then you can update or uninstall your problematic third-party software.

  • Can't Run SPSS with Mountain Lion

    I recently upgraded to Mountain Lion and then installed SPSS 21. I am unable to get SPSS to work and I receive the following error message when I start the program: Serialization scheme was not recognized inet:Local Computer:0.
    I then get presented with a popup window asking me to specify my server login: local computer.
    Might anyone have any suggestions to fix this problem. I have been unsuccessful checking the SPSS support documents and just looking around the web, and my campus IT support hasn't had anything to offer.
    Some further notes:
    SPSS 20 did not work after I upgraded to Mountain Lion, but SPSS states that version 20 is not fully compatible with Mountain Lion and users should upgrade to version 21.
    Another discussion thread regarding difficulties with starting SPSS suggested creating a new user with Administrator priviliges and running SPSS under that user. This solution has not worked for me. Likewise, another suggestion of starting SPSS from terminal mode has not solved my difficulties.

    Unable to open SPSS in MAC due to error Serialization Scheme was not recognized

  • IMac-27inch model (late 2012) running slow after Mountain Lion 10.8.5 supplemental update

    I have the iMac 27-inch (late 2012 model), 8GB RAM, 1TB Hard Drive.  All of a sudden after the Mountain Lion 10.8.5 Supplemental update it started running like molasses (apps take forever to open, takes forever to wake out of sleep, long boot up times, etc.)  I ran verify disk, verify disk permissions, etc.  I found that when I ran verify disk permissions, it stated that the iTunes permissions weren't right so I repaired disk permissions, reboot, still same problem.  Ran verify disk permissions again, once again iTunes permissions issues, repair disk permissions, restart, same problem over and over again like Ground Hog Day, please help...

    First, back up all data immediately, as your boot drive might be failing.
    Step 1
    This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
    If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
    Triple-click anywhere in the line below on this page to select it:
    syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|find tok|n Cause: -' | tail | open -ef
    Copy the selected text to the Clipboard (command-C).
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V).
    The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
    A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
    Step 2
    There are a few other possible causes of generalized slow performance that you can rule out easily.
    Reset the System Management Controller.
    If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
    If you have many image or video files on the Desktop with preview icons, move them to another folder.
    If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
    Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    Check your keychains in Keychain Access for excessively duplicated items.
    Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
    If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
    If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
    Step 3
    When you notice the problem, launch the Activity Monitor application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
    Step 4
    If you have more than one user account, you must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

  • Macbook Pro runs slow using Mountain Lion?

    I have access to use a Macbook Pro which is running Mountain Lion. However, the MBP runs very slowly and the coloured wheel is constantly spinning with almost everything I try to do. I do not know why and would like to be able to have a normal running MBP.
    I wondered whether installing Yosemite might help? Or I have read some posts about resetting the System Management Controller. Please can someone give me some advice as to what to do that will work?
    Thank you

    Installing Yosemite will probably NOT help. 
    Slow MBPs usually are a result of a failing HDD, third party software (often so called 'cleaning' or 'performance' applications) or unnecessary AV software.
    SMC resets are good for certain hardware issues and will also probably NOT address the issue.
    Download and post an Etrecheck report which may provide some clues:

  • MacBook Pro runs slow after Mountain Lion installation

    I have a mid-2009 13" MacBook Pro with 2.2g Ghz processor, 2 GB of RAM and 160 GB encrypted disc.
    After installing Mountain Lion and the recent upgrade OS X 10.8.1 (12B19), the system runs noticibly slower than with Lion, which ran slower than the previous version.  This shows up in opening and closing programs, rate that drop down windows appear when something is clicked on the task bar,  rate that windows open and close, rate that the dock comes up and the icons expand when the curser is moved over them, etc.  
    Due to my type of work, I need to encrypt the disc.  I know this is costing me some speed.  I unencrypted the disc and it ran noticably faster, and when I re-encrypted it seemed to run faster than before unencrptying and re-encripting.  I have repaired permissions and verified the disk OK.
    Somewhere in the build up to Mountain Lion release I thought I read where 4 GB of ram was recomended for Mountain Lion, allthough now the specs indicate 2 GB is OK.  In activity monitor, the pie chart for system memory seems to always remain less than about 40% of active memory (yellow).
    What recomendations does the community have to increase the speed of operations back to when this system was new?
    Dave

    I was having the exact same problem.  My MacBook Pro was seriously close to unusable how slow it was.  On a different thread, someone recommended I reset the VRAM and PVRAM (not sure about those initials).  Shut down computer.  Rebooted while holding down Command-Option-P-R all at the same time until I heard the second startup tone and then released.  I noticed an improvement in performance immediately.

  • Macbook running slow after mountain lion update

    why? i have 2 gb of RAM, that should be more than enough, right?
    firefox is running slow, everything is freezing. i have barely used any of my hard drive space with it being at 225.61 gb free out of 249.2 gb.
    its really frustrating.....

    Two gb is the bare minimum for running Mountain Lion.
    The model 7,1 (Mid 2010, White Unibody) can use 8gb of 204 pin 1066mhz PC3-8500 RAM
    These are good online stores for Mac compatible RAM
    OWC http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_Whi te - They offer Mac tested RAM at very good prices.
    Crucial Memory http://www.crucial.com/ - good place to buy RAM from all over the world. They also have an excellent memory selector that allows you to choose memory based on your computer's model
    Data Memory Systems http://www.datamemorysystems.com/apple-memory.asp - another good, cheap place to buying RAM if you live in the U.S.
    Here are video instructions on replacing the RAM on the White Unibody.

    If you don’t have the tools to open up the MacBook OWC has a set for $5.

  • Mail very slow in Mountain Lion

    The upgrade to Mountain Lion went smoothly but Mail works really badly afterwards.
    When sending an email, it takes a few minutes before the mail goes out. And that's with any size message.
    Auto-completion of mail addresses while composing takes multiple minutes. Even after it finally comes up with a list of email addresses, pressing enter on one also takes minutes to acknowledge
    At various times, hitting the mail icon on the dock has no effect. The same is true with Command+TAB
    Overall, the unresponsiveness is painful and making me wish I hadn't upgraded

    This didn't solve my problem. First of all:
         $ ls /Library/Preferences/com.apple.mail.plist
         ls: /Library/Preferences/com.apple.mail.plist: No such file or directory
    but I do have the file in my local Library:
         $ pwd
         /Users/spate/Library/Containers/com.apple.mail/Data/Library/Preferences
         $  ls -l *mail*
         lrwxr-xr-x  1 spate  spate     64 Jul 26 11:08 com.apple.mail.LSSharedFileList.plist@ ->      ../../../../../Preferences/com.apple.mail.LSSharedFileList.plist
         -rw-------  1 spate  spate   6733 Jul 27 08:24 com.apple.mail.plist
         -rw-------  1 spate  spate  56130 Jul 27 08:12 com.apple.mail.plist.bak
    This is after I moved com.apple.mail.plist to com.apple.mail.plist.bak and then started Mail again. As you can see, it created a new, much smaller com.apple.mail.plist
    No luck - just as painfully slow as before!
    This is horribly painful!
