Why do I have to force-quit Thunderbird every damn time? Using 31.5.0.

Every single time I use Thunderbird (has been going on for awhile - and this update tonight didn't change anything, it will not close down properly. Doesn't matter if I use File menu to exit or do Cmd + Q. It just sits there, and when I do Ctl + click, I see "Application Not repsonding" and need to force quit to exit it. BTW, am running Yosemite (10.10.2) on an Early 2008 20" iMac with 4 GB 800 MHz DDR2 SDRAM.

My ical froze and keeps trying to process a cut and paste that I added to the calendar. I have to force quit but the next time I open it is still frozen. Can't use at all. Help!

My iCal has frozen when I tried to add a cut and paste to the calendar for notes on a meeting I'm attending. I have to force quit but the next time I open it is still frozen and everything I've tried doesn't erase the message so I can continue using. Can't use at all. Help!

I have the same problem--have you found a solution?

Why do I have to Force Quit iTunes so often?

On my old G3 iBook I remember I had to Force Quit iTunes (can't remember which ancient version that was) sometimes when it 'froze' after I clicked a new track title on a CD that was in the Drive.
In iTunes 6, this never ever ever ever ever ever happened. Never. Not once. Ever. I silently congratulated Apple on eliminating that annoying particular little glitch.
Now I've recently downloaded iTunes 7 - it's happening again !! Several times when I click to play a different track on a CD in the drive, I get "iTunes (not responding)" and I have to Force Quit. This is REALLY REALLY annoying. Why has this old fault returned?
(btw I just saw the thread below mine, about iTunes needing Force Quit after playing 2 tracks on a CD? This is NOT the same fault. iTunes will happily PLAY a whole CD without complaining - the problem occurs after I double-click to play a different track while another one is still playing.)

FWIW, I have had a similar problem, where iTunes froze on random songs at two seconds into the song. I would have to force quit, then restart. This occurred when I put in a CD to play from the beginning, while I did other things. I have not witnessed your circumstances when clicking a new track to play. I do not do this often, except after I restarted iTunes to continue the CD.
I just deleted the com.apple.itunes.plist file in ~/Library/Preferences and so far, so good.

Why do I have to force quit Garageband?

When I start a new song or if I 'save changes' to an old one, the program 'unexpectedly quits'.... but I have to 'force quit' Garageband before it will start again. I'm recording ambient sound with an external mike but I'd like to be able to use it to arrange songs if I could. Am I asking too much of it? I mean, it's supposed to at least be able to do a bit of straight recording isn't it? It's got a gig of sdram. Thanx in advance

Have you tried unchecking the "automatically check for newly published albums" checkbox in prefs / web. Do this for each online account. This worked for me. The source to this solution was on Flickr.

Why do I have to Force Quit applications?

Pages 09, safari and iCal won't shut down. I have to force quit the application every time. I have reinstalled OS X (tiger that came with the iMac G5) and upgraded it through Software update. It is very annoying. I have also used disk utility and vertified the HD, which seems to be fine. Also ran OnyX. Also tells me everything's fine. Anyone know what might be causing this behaviour? Thank you.

One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for action in Safe Mode, (do those APPs Quit OK?)...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.
Reboot, test again.
If it only does it in Regular Boot and not in Safe Mode, then it is likely some 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Also see what is in System Preferences>Other Row.
Also look in these if they exist, some are invisible...

Why do I have to force quit mail?

Mail almost all the time never closes by closing it, I have to force quit it.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

I have to force quit mail every time I want to shut down my macbook

I have to Force Quit Aperture all the time

Whenever I sit down to edit photos, Aperture hangs and I have to Force Quit and start again. This happens all the time. I used to think it happens only when I process raw images, but I've found that it happens with jpegs too. Apple once told me I should Repair Permissions and/or Repair Database and/or Rebuild Database. I did all three last night. This morning Aperture hung on the first picture I tried to crop. I am starting to get so frustrated that I am thinking I should change software because Apple doesn't seem to care about this product as I could find no support numbers to call.
Does anyone have any ideas on how to fix this?

Hi jimchall -- welcome to the Aperture user-to-user forum.
I think many people have experienced similar frustration. Determining what's causing your problems is going to take time, however.
My number one suggestion is: don't force quit Aperture. Which brings up the question, how do you know Aperture is hung up? Until your problems are sorted, it's a good idea to keep the Aperture Activity Window open -- it will keep you semi-informed about what Aperture is up to. (If you are comfortable with computers, I recommend also using iStat Menus 3, or equivalent, to monitor your memory, disk, and CPU & GPU status.)
Aperture does a lot of work in the basement (as it were) while you are busy (or not) decorating the upper floors. This is most apparent after large imports (of, for instance, an iPhoto Library), when the downstairs work can completely suspend any work being done upstairs. No notification is given to the user when this happens -- you see the spinning pinwheel, and the Force Quit utility will even report that Aperture is not responding -- but, in many many cases, Aperture is, in fact, working. Let it work. In my experience with Aperture, force-quitting almost always makes problems worse, and should be avoided.
Some of the first problem areas to rule out are from hardware. What computer are you running Aperture on? How much RAM? How big a drive? How much free space on that drive? Where is your Library located? Are you having any problems running any other software? Are you using any unusual peripherals? Is your network in any way involved in your Aperture set-up?
Then, of course, software: are Aperture and OS X completely up-dated? Have you modified the OS in any way? Has Aperture ever worked properly?
The next general trouble-shooting steps are to (temporarily) disable two of the more processor-intensive parts of Aperture. Go to the Preferences dialog, and turn off "Faces", and turn off "Share Previews". (Once Aperture is working properly for you, these can be turned back on.)
Then reboot, launch Aperture -- and let it run for several hours (keep you computer plugged in and set to not sleep). It can take many hours -- days even -- to completely process a very large import.
You have taken the steps to confirm that you Library is healthy. Stick with it, and with the help of the people on this forum you should be able to figure out what is holding you up.

Spinning Beachball of Death . . . why did I have to Force Quit ???

Folks:
Last week I had an episode of multiple recurring "application not
responding" errors while trying to select and scroll down through a couple
hundred pages of text in a manuscript of approx. 1.8 MB in size in my word processor, Mellel. As I scrolled down about half way the spinning beachball started spinning and the scrolling process became slow, sluggish, and then unresponsive . . . . I force quit and repeated another 2x to no different response. Finally did "select all" to whole doc and then had to go in to the few pages that I had originally not wanted to select and change them to back to what I wanted . . . a little bit "bassakwards" but I got it done the old fashioned way. Now, when I attempt to "save edits" as I'm going thru my doc the beachball will spin for different periods of time. This is mostly an all text doc with just two (2) photos that have been "inserted" into the doc--seems like the photo's are smaller files than the original, and about 250 pp.
So, the question is is mr Mel (Mellel) trying to tell me something about my system; is this perchance a sign that Macinto II (the 2nd HD in the iBook) is coming close to its ultimate demise? A few years back I began having "issues" with mr Mel that eventually were shown to be signs of the end of Macinto I (named after the famous Seminole Indian chief who fought the US Army to a draw in the Everglades). I had just run the Apple Hardware test just a few days before this
recent episode all happened and it seemed to be OK. But it has been mentioned
here that mr Mel is "processor intensive" and could be just testing the limits
of my 2nd HD??? OR is the test over and all that is left is the funeral pyre for
Macinto II??
Would essentially a 2MB Mellel file be too large for my 933 MHz G4 iBook
with 640 MB DDR SDRAM running Mellel 2.2.7 (build b9) on 10.4.11 . . . to handle
even if it was totally in fighting condition?? Or is the probably 3 year old HD
being brought to expiration by having to deal with running the features that are
brought to the table by mr Mel??
Thanks for any thoughts,
eep

Word processors typically load a large portion of a file into RAM for editing. When more of the document is needed it pages out the unneeded portion and reads more of the document into RAM. So in practice no document is too large. None of your "surmises" would seem to make sense.
A more likely scenario is disk corruption or file corruption assuming the hard drive isn't failing. Continued forced shutdown of the computer is a sure fire way to corrupt a hard drive if not cause it fatal damage.
I suggest reading the following:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard.
OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. Carbon Copy Cloner (Donationware)
6. SuperDuper! (Commercial)
7. Intego Personal Backup (Commercial)
8. Data Backup (Commercial)
9. SilverKeeper 2.0 (Freeware)
10. MimMac (Commercial)
11. CloneTool Hatchery (Shareware)
12. Clone X (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.

Why do I have to force quit firefox? All my plug-ins and add-ons are disabled, and still firefox cannot quit.

Apple Q and Firefox > Quit Firefox do not work. The only thing that works is FORCE QUIT.

If Firefox hangs (stops responding) when you try to clear the cache and cookies and you have already disabled all Extensions and Plugins from the Firefox (Tools) '''Add-ons''' manager, then the problem could be one of the files in your [[Profiles|Firefox profile]]. See [[Firefox hangs]] and try creating a new Places database, by opening the profile folder (via "Help -> [[Using the Troubleshooting Information page|Troubleshooting Information]] -> Show in Finder"), then quitting Firefox, and deleting the file(s) '''places.sqlite''' and '''places.sqlite-journal''' (if it exists).
If that doesn't help:
Try creating a new Firefox profile for testing (this will not remove your existing profile ; you can choose between the two in the Firefox Profile Manager). See [[Managing profiles]] for details. For other ideas, see [[Basic Troubleshooting]].

Have to Force Quit Mail every time

Since upgrading to 10.6.4, I've had trouble quitting Mail.
I manage two email accounts through Mail: one MobileMe and another from work.
After running for an extended period of time, it will not accept the Quit command. It requires a Force Quit.
When it is having this problem, the Activity Monitor shows that Mail is taking 30-45% of the CPU.
It doesn't do it immediately, though. Mail has to be launched for some time.
If I open it, perform a few tasks (check mail, send mail, etc), and then try to quit, it will do so just fine.
Does anyone have suggestions as to what is causing this?
Thanks in advance.
Tim

While I am not saying I know exactly what is going on, I do have a suggestion that might help as it has helped me in the past.
First, Do a permission repair via Disk Utility. Then check if that helps.
If not, then another suggestion would be to delete the .plist file from user/Library/Preferences/com.apple.mail.plist
Note however, that this will mean you have to set up your accounts and preferences again.

Firefox freezes upon opening up the program. Have to force quit (mac) every time. I've reinstalled 5 times.

I have no idea what's causing this. I used Firefox exclusively for years and one day it just froze. I tried rebooting my computer, and eventually deleting and reinstalling Firefox multiple times. Nothing has helped. It was several months ago that the problem began, so I don't recall exactly what I was doing when it first happened. I've searched my hard drive for leftover remnants of an old Firefox program that might be causing problems, but I've found nothing. I've used Safari ever since and that works fine. I just prefer Firefox so I'd like to be able to use it again. My mac is about 6 years old, using OSX 10.8.5.
Thanks!

Unfortunately my music software is not compatible with the new Mac OSX update (it may be in the coming months), so I have to stick with this one for now. Do you think Firefox would really just shut me down like that, just because I'm on a previous operating system?
I guess I'll just stick with Safari until my Native Instruments Maschine II allows for the Yosemite update.
Thanks for trying to help out!

I keep getting told that i have run out of application memory and have to force quit applications. Not sure why this happens or what I do to fix it.

I keep getting told that I have no more application memory and have to force quit applications. Why does this happen and how do I fix it? This issue has only started since I started using Mavericks 10.9.2.

Have you checked how much space you have left on your HDD? You may find some useful information here:

With the amount of information you've provided it's impossible to offer a potential solution. We can't see your computer so we need to know the details of your problem and setup, i.e.:
what version of iPhoto are you using?
what system version are you running?
does this only happen when you try to quit iPhoto?
what fixes have you tried?
where is your library located?
did you apply any updates or upgrades just prior to the problem occurring?
are you running a "managed" or "referenced" library?
what type of Mac?
how much free space on your boot drive?
Happy Holidays

TS3276 hi after updating to Mountain Lion, it becomes difficult to quit Mail, always have to Force Quit. And while Mail is on standby, the fan keeps on running full power, the laptop is hot. Why is this happening?

If your computer was hot it wasn't asleep - it either didn't go to sleep or it work up after you put it to sleep. I've seen both things happen. First, read this article and follow the instructions.
1) For the next few days/weeks pay attention to the blinking light on the front of your computer when you close the lid. Don't put the computer into your backpack/case until it begins to blink. Wait a minute or so after it starts to blink to make sure it doesn't stop blinking - the signal it woke back up.
2) having followed the above instructions, if you take the computer out and it is hot again or if you take it out and discover it has powered down (you'll know this because when it starts up the battery will be drained and you'll see a progress bar over a ghostly display that will eventually become normal) immediately start the Console program and perform a search on 'sleep' and then 'wake'. This should bring up all the recent log files about sleep state changes (going to sleep and waking up). You should see one for when you put the computer to sleep and put it away and the next one should be just after you got it out. You'll find at least one though that shouldn't be there. That will tell you when the computer work up (when it shouldn't have) and might give a clue as to why.
One of the whys could be a magnet that is making the computer think the lid has been opened.

Why do I have to force-quit Thunderbird every damn time? Using 31.5.0.
