Mac 10.5.8 browsers crashing – applications not responding

Hello,
I'm having big problems with my Mac 10.5.8. I tried verifying the disk on Disk Utliity but no errors showed up.
Basically, my browsers (Safari, Firefox, Google Chrome) crash as soon as they are opened. Some other application stop responding as I'm using them and I have to force quit. The computer as a whole is very very slow to respond.
If anyone has any advice I would really appreciate it. I need this computer for work.
Thank you!

I am having the same problem. It's been happening for several months. Firefox, Safari and Chrome all crash. I've avoided updating them and in fact went back a couple versions in Firefox, but no change. I can be working on Firefox for an hour or for 30 seconds. Either way, it just crashes. I can immediately restart it, and it will work for an hour or 30 seconds.
No visible pattern, and it is not website specific.
I am running a MacBook with 10.5.8 2.1 GHz Core 2 Duo, 4 GB 667 MHz
Any help is greatly appreciated.

Application Not Responding - Mac OS X Lion & CS5

I keep having issues with my DW CS5 (11.0 Build 4993) & Mac OX Lion. I bought a new MacBook Air and installed DW CS5 on it, I did all the updates too for DW, but I'm having issues with it freezing and then crashing and not relaunching. I do some simple change on a website and the application freezes and says Application Not Responding. After force quiting I try and relauch and I get the green welcome screen like it's launching but then nothing comes up and it says Application Not Responding (ANP). I've tried restarting and sometimes that will make it so it actually launches completely but then after a while it starts up again with the ANP. I considered that maybe the MBA wasn't quick enough, but I think it's plenty powerful for doing DW. When I got back to my iMac at home I started to have the same issues after upgrading it to Lion. There seems to be an issue with CS5 and Lion. Any ideas?
Thanks,
Cody

CS5 was a fresh install on the MBA, on my iMac it was a fresh install as well (but back when I got the iMac a few months ago and was still using SL). I do have extensions on my iMac, but not on my MBA so I don't think that could be the cause (although I may try it and see). I usually would have Firefox, Safari running as well. Sometimes Photoshop and iTunes would be running too. If an error message does pop up it's usually the Mac's "Application Quite Unexpectantly" is that the type of message I should try and provide to Adobe?
I don't believe a specific action invokes the freeze/crash I've had it happen when I try and open an HTML page, when I try and save an HTML or when I try and select text to make a text change. I'll try and note exactly what I was doing the next time it happens, it seems to be speratic but very annoying cause it can take a few times of force quitting and relaunching to get DW to open back up.
Thanks,
Cody

Keynote Crashing - with Lion. Most often when I switch out of Keynote to another program - Keynote freezes - says Application Not Responding. If I save the Keynote before switching, it does not crash - only when it says it is an "edited" file....help

Keynote Crashing - with Lion. Most often when I switch out of Keynote to another program - Keynote freezes - says Application Not Responding. If I save the Keynote before switching, it does not crash - only when it says it is an "edited" file....help

I posted this on another thread. See if this works:
1) Uncheck "Backup previous version" in Keynote's Preferences.
2) Make a duplicate copy of your file that has issues and save it.
3) If you still get spinning wheels from switching between apps after editing or 10 seconds of inactivity, manually save with command+s. It may beach ball here but be patient and wait for it to finish! Try editing and resume doing work now.
Command+s may be a bit slow but I think that might be normal since the files are so big.
Good luck and let me know if this works.

Mac is running SUPER Slow, applications not responding when i open them, Beachballs everywhere

Whenever i open an application (Take Google chrome for an example) it bounces like 20+ times, then on activity monitor it says "Application Not Responding". Whenever i type too fast on spotlight or finder, my whole desktop freezes, im suspecting this can be maybe HDD failure, i have repaired my MacintoshHD probably 3 times this past week. I have 150GB free out of a 250GB hdd, and i have 4 GB RAM. PLEASE HELP! Im currently enrolled in college and this is vital and needs to be fixed ASAP.

While I tried to open I-photos on my MAC it says " can't open application not supported by this mac"?

While I tried to open I-photos on my mac it says " can't open application not supported by this mac"?

Restart the computer in safe mode. Certain caches maintained by the system will be rebuilt.
Safe mode is much slower to start up than normal.
When the login screen appears, restart as usual (not in safe mode) and test. There's no need to log in while in safe mode.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t start in safe mode. In that case, ask for instructions.

ITunes 11.2.1 freezes when I connect my iPhone 5. 'Application not responding'

Hi,
Recently I upgraded Mavericks. Since then I cant sync my phone anymore. iTunes works fine untill I plugin my phone. Then the spinwheel comes up and stays there forever. In dock it says 'Application Not Responding'.
iPhone 5, iTunes 11.2.1, Macbook Pro 10.9.3 2.6 GHz 8Gb
Does somebody can help me out? That would be very very nice!

Hi BlackNikes
I had exact same problem, but have now resolved it. If your problem is the same as mine your SyncServices folders have been corrupted while itunes was updated.
See my post or spyder683 post at https://discussions.apple.com/thread/6223064?start=60&tstart=0
I am running Mavericks 10.9.3 and updated itunes to 11.2.0 and then experienced problems with itunes crashing, 11.2.2 didn't resolve the problem. I found iTunes worked fine if all my other devices (iphone, ipad, ipod) were turned off, as soon as I powered any one of them up and itunes detected them over wifi or USB itunes then froze with the dreaded colored ball spinning.
In Mavericks 10.9.3 the SyncServices folder is not visible going into the normal library/Application support folder, your instructions below took me to a different area in the system, or at least made these folders visible. Following your instructions I was able to locate and delete both SyncService & SyncServices folders and I launched iTunes again while my devices were powered up and the issue has gone. Bliss!!!
Many Thanks

Hi Culero,
The fix of deleting the SyncServices folder is for Mac systems. From your desktop / finder, click the "Go" menu at the top, then "Go to Folder ..." Paste this into the field: ~/Library/Application Support
The SyncServices folder should be in there. I had both a SyncService and a SyncServices folder. The second one should, when deleted, help with the problem you and I both had of iTunes freezing when an iOS device is plugged in.
Hope this helps

Help please-"Application Not Responding" for Safari and Mail

I read in one discussion that if Safari is slow, you can go to Font Book and select the fonts with a bullet to get rid of duplicate fonts. I did that, and then decided to disable some japanese fonts I don't use.
Now Safari and Mail don't work. Mail won't open at all, and Safari launches but doesn't load and I get the spinning wheel.
I used Disk Utility to fix permissions, and that didn't solve the problem, and now my Disk Utility also says "Application Not Responding".
I also went back to Font Book and enabled all the fonts I disabled. Still nothing.
( I can use Netscape-so it's only Mac applications I guess)
Any help is very much appreciated.
Thanks!

Wow- i fixed it! I remembered that when I was in Font Book originally, there were some fonts disabled, and I enabled them.
I couldn't remember EXACTLY which ones, but I disabled some I thought were the ones, and VOILA!
Mail works, Safari works...what a relief!
And it only took me HOURS...oh well.
If this might help anyone, here are the fonts I disabled again-

Anyone know if I should throw these fonts away? maybe a stupid question, but I'm not very good at this stuff and hesitate to change anything.

Microsoft Word Freezing Repeatedly, Application Not Responding

Just wondering if anyone else was having issues with Microsoft Word from MS Office 2008, where you open the application, you type a few sentences, and the application freezes with the spinning circle of death that won't go away until you click the dock where it says "application not responding" and do a force-quit? You can leave the circle spinning for 10-20-30 minutes, and it never goes away.
Now for the weird part--this error only happens for me when I'm using a specific document on my computer. I can open Word, start a new document, type several paragraphs of text, and it works fine. But I've been working on an existing paper for about two months that all of a sudden started causing these freezes/crashes when editing it. It's about 30 pages roughly, no images, no big inserts that would take up a lot of memory (116 kb in size). And up until today, there were no problems. So why all of a sudden can't I edit anything on this paper without freezing the program?! I downloaded the Microsoft Office 2008 Service Pack 1 that was just released after this problem started, and ran all the recent Java and program updates through Software Update with computer restarts. I even copied the text from the Word document I was working on, pasted it into a new document, tried saving it as both .doc and .docx, and again the program still freezes when working with that text in a new file. This one baffles me. It's like the text within a document is somehow freezing the application. One thing I did notice is that the freezes seem to happen when I'm scrolling using a mouse wheel. Not always, but quite a bit. I suppose this is some memory issue related to several pages of text that the program can't render or process when you add new lines of text or scroll, but again, I can't figure why this paper I've been working on for months all of a sudden decided to start freezing Word today. Can you really only have 30 double-spaced pages of text in Word before it crashes?
Looks like I've found my reason to switch to Open Office, since I'm 3-4 days out from a deadline. Any other solution strategies would be welcome. Thanks.

Same problem here - Microsoft Word 2008 (update 12.1.7) will open fine, and then start the spinning pizza of death. Only way out is to force-quit the app. I've tried:
1) deleting plist and font cache files
2) uninstalling MS Office 2008, reinstalling and then re-applying updates 12.1.0 and 12.1.7
3) confirming that Apple's Font Card.app can verify all fonts
No luck. Currently I can't open any MS word doc without the spinning pizza of death.
If you are lucky enough that these symptoms only happen with a specific Word .doc file, I would see if the PC-originator could re-save the file as .RTF and resend. If you can then open it OK, you could revert back to .doc (or .docx) format. RTF format is Microsoft's interchange format. If there are anomalies in the .doc file, saving as .RTF can sometimes clean them up. Once done, you can revert back to native MS Word format.

Mouse over dock icon no longer indicates "application not responding"

A very convenient feature seems to be missing from Snow Leopard. In prior versions, if an application was not responding, holding the cursor over its dock icon would display "[Application] Not Responding" and also an option to Force Quit. This status message does not appear in Snow Leopard.
Are we to assume that if we click and hold on a dock icon and "Force Quit" is presented as an option, that the application has stopped responding?
Suggestions?

Thanks!
So if I click and hold a dock icon and "Force Quit" is shown instead of "Quit" would that indicate that the particular application is in the midst of some process and simply unable to respond?
Should I simply allow more time for the app to finish whatever it's doing?
it could be either. sometimes an application is busy and is showing as not responding but will come out of it after a while. but sometimes it's truly hanging and then you have to force quit it to get rid of it. there is no way to tell just by looking at the dock. give it a bit of time and if it's still not responding then force quit. but if it's happening all the time then you may have problems with your system.
In particular, here, I've launched DiskWarrior 4.2 on a Mini (via Screen Sharing from my Mac Pro) in an attempt to rebuild directory on a My Book 1TB external drive connected by FireWire, which Disk Utility indicates needs repair but DU cannot repair. Ideas?
so what does disk warrior say when you try to rebuild the directory? and you should also verify the internal drive on the mini too.

Application Not Responding Creative Suite

Having major problems with Application Not Responding in Creative Suites 5 & 6. Whenever trying to quit applications, more than not have to force quit. Would like to be able to quit out of Adobe Apps without force quitting. Also get a lot of spinning wheel of death, that forces us to force quit and restart. Any help would be appreciated.

What system? This behavior has nothing to do with the programs per se, "crashes on exit" always depend on systemic issues. provide the necessary details and crash info:

Mavericks freezing / Applications not responding

Before I start this problem is not isolated to one machine. We have around several MacBook Pros from 2012 onwards, Retina MacBook Pros and iMacs.
The Retina laptops came with Mavericks installed.
So our general issues are:
- Fan noise loud
- Machine with no acitvity starts wurring up
- All applications not responding then having to hard restart
- Laptop running hot
This has only happened since release of Mavericks and is not SSD related as we have had non SSD related Macs with the problem.
Almost every machine I've listed above has experienced the issues above.
Does anyone know a fix for this or is Mavericks just not worth using?

HA IT --
Are you all running some kind of Security or AV program on your Macs? Something that would be oconstantly scanning files?

'Application not responding' message

I am new to iChat (and to Macs generally). The other day I tried out iChat (having set up a .Mac account) and everything seemed fine. But ever since then when I launch iChat the Buddies window comes up and the little spinning colour cicle goes round for ever and from the Dock the menu item at the top says 'Application not responding'. I have seen that others have had this problem but I don't seem to be able to access the answers they got. Any help would be much appreciated.

Hi The Old Wreck,
Did you run through these screens ?
http://www.siriusaddict.com/ichat.html
These should have enabled you to type in your Screen Name when you selected the correct account type.
If you are not sure then delete all the .plists for iChat.
This will mean going to /Users/(your Account)/Library/Preferences
(Open your hard drive then Users then your Account (little house iCon) then the Library in there then Preferences)
Find these items
com.apple.iChat.AIM.plist
com.apple.iChat.Jabber.plist
com.apple.iChat.plist
com.apple.iChat.SubNet.plist
com.apple.iChatAgent.plist
Put them in the trash (Delete them)
Try iChat again.
It will make you go through the Start Up screens again.
Also check the Address Book.
Find the Me Card (Head and shoulders icon)
Make sure this shows your details including your @mac name.

Application not Responding - CS5, OS10.6.8

If I have a CS5 application running w/ a document open, and switch to another running application, when I try to go back to the CS5 app (click on the document window or select the icon in the dock), I often get the spinning beach ball and the "Application not Responding" message (if I control/click on the dock icon). I need to Force Quit the app & restart. Happens frequently in InDesign, Illustrator & Photoshop. I'm on a MacPro w/ 6GB ram. Anyone else experiencing this / have a solution? - thanks

John, I deleted Extensis Suitcase Fusion and re-installed InDesign. It worked for a short time and now its crashing again. The crash report is still showing the problem to be Suitcase. What else can I do to get rid of all traces of Suitcase.
Bruno is correct, un-installing InDesign doesn't remove the Suitcase Auto-Activation Plugin from InDesign.
0xa9b9000 - 0xab39ff3 +com.extensis.AutoActivationPlugin.ID7 (3.0.4.11 - 3.0.4.11) <C60215EF-E853-7053-497C-7AC0D279746A> /Applications/Adobe InDesign CS5/*/ExtensisFontManagementIDCS5
I'm not sure why it is indicated with a * instead of a precise folder name, but that's saying there is a ExtensisFontManagementIDCS5 plugin (probably in the Plugins folder!) inside /Applications/Adobe InDesign CS5 that is causing the fault. So if that's still there, remove it. (Perhaps Manage Plugins from Suitcase will do it for you. I'm not really familiar with Suitcase. But you can just remove the file by hand).
By the way:
Version: 7.0.0.355 (7000)
You really should update InDesign to the current patch release, 7.0.4. There are quite a lot of bugs in 7.0.0 that have been fixed. (Perhaps you had updated previously but those were lost with the re-install...)

Application Not Responding with 10.9.3 Upgrade

I have upgraded my software to 10.9.3 and now I am having serious issues with all of my applications just freezing up with all of the applications saying Application Not Responding. I am using a iMac 2.8 GHz core, 4G Memory, 800 Mhz. I have as much additional memory installed as I can.
Thanks,

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
     computer and after the chime press and hold down the OPTION key until the boot manager
     screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
     Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).
If 4 GBs of RAM is your computer's maximum, then you really should not be running Mavericks. Your best choice for such an older machine would be Snow Leopard.

Max OSX10.10.3, Adobe acrobat/document cloud goes into "application not responding mode" right away. must force quit. cannot use the program. Why?

Have never been able to get this application, adobe acrobat dc, to work on my mac. Constantly goes into "application not responding" mode. Happen to anyone else and know how to fix it?

Hi Nicholas,
Verify if Protected View and Enhanced Security are Off. Go to Acrobat-> Preferences -> Security (Enhanced):
Also having too many fonts active can hurt the performance of any application.
