IMac freezes but mouse works

my late 2009 iMac has now frozen twice over two days since upgrading to Yosemite. the mouse moves around on the screen, and all appears normal, but everything is frozen and I can't click on anything. So far a power button shutdown seems to work and everything goes back to normal. I am wondering if this is a Bluetooth issue? Or not.

I hate to say this, but the pixel anomalies indicate a faulty V RAM chip, which is soldered to the logic board
You may have more that one problem, the pixels being one, and the hard drive and/or the PSU being another.
At this point, you probably need to take it in and have it looked at, then you will have to decide whether it's worth repairing, or whether you will just get a new one.
In any case, please let me know what happens,

TS4135 Imac freezes but mouse still work.

My Imac freezes everytime I try to load an app. Rather its a webpage on safari, playing videos on sites, iTunes, photobooth etc. I can't even load the applications folder without it freezing on me. The dock & keyboard shortcuts are frozen too. The only thing that moves is the mouse cursor, but its no good if I can't open or close anything. I wiped out my Imac to factory settings, thinking it would clear ram/men space and that didn't help. Sigh. I need help. What can I do? What should I do? Is this a firmware or system update problem? Help me please!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
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.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; sudo crontab -l; } 2> /dev/null | open -f -a TextEdit
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; crontab -l 2> /dev/null; } | open -f -a TextEdit
Step 4
ls -A /e*/{la,mach}* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -f -a TextEdit
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Imac G5 freezes, but mouse works. Wierd pixels right before it freezes.

Hello everyone (Miriam, I hope you find this post).
Problem:
I have an older imac G5 (20" - without isight). Worked fine for the longest time, then lately it started freezing at main screen. Mouse pointer works, but nothing is accessible. First, started freezing after 5-10 minutes of use. Then, in the span of a few days, it locked up right after entering the main screen (after blue apple screen startup).
What I did so far:
Following the imac manual, I did a hardware test after reading about logic boards and power supply issues. Used hardware utility from startup disc and everything passed. Therefore, I reasoned that it was a software issue.
Next, I used disc utilities to repair a few permissions and HD volume. Minor repairs done. Started getting passed blue OS loading screen, but still freezing at main screen.
Finally, I tried to reinstall my OS, using archive/install feature (don't want to fully reformat because I can't access files to back up). First disc - no problems. When it asked for second disc, comp froze again. Now, it freezes at blue screen, before blue apple loads the OS. Can't even get to main screen anymore. Tried it again, but same deal.
Question:
Any suggestions before I take it to apple? My warranty has long since expired, so I'm afraid of incurring large fees. I would try a full reformat, but there are certain files I need to backup, but can't do so due to the inability to even open a folder. Also, it'd be greatly appreciated if someone could point me to a thread relating to backing up files when comp freezes, therefore main screen inaccessible. If I could back up certain files, I could do a full HD reformat, then report the results here.
Not sure if this matters, but my imac version was one of the models that needed the free extended warranty for the power/capacitor issues. Repaired for free, no problems until now. Also, fan spins hard during startup, but very quiet during gray apple load screen - then freeze at blue screen. No hardware or software added recently.
Sorry for such a long post. I figured the more detailed the info., the better the responses would be. Thanks again Miriam for the redirect. I'm indebted to you!

27" iMac freezes, but mouse moves. 10.6.8. For 2 days, same error with volume info. Repaired disk from install disk twice.

Here's more info. Bought the iMac in Nov. 2009. It's been one with lots of problems, including a new mother board. Haven't had any big troubles lately until now. The exact error is:
Invalid volume file count
(It should be 888333 instead of 888334)
Invalid volume directory count
(Should be 221900 instead of 221899)
These were the only error messages. I did use Disk Utility to repair the disk, twice in two days.
2.66 GHz Intel Core i%
12 GB 1067 MHz DDR3
(219.55 GB available)
I'm not sure what else would be helpful to know.
Can someone tell me what's up, please?
Thanks! Jane

It would appear Disk Utility cannot repair the problem. This is not a big problem, but fixing it will require you to purchase and use Disk Warrior. Alternatively, you can backup your files, erase the drive, reinstall Snow Leopard, then restore your files.
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Screen Freezes but Mouse Still Moves

Hey I have an iMac with a 2GHz Intel Core 2 Duo processors and I am running OS 10.6.7 and my screen freezes (sometimes goes to a black screen or many lines repeated) but my mouse is still able to move, then I have to shut down manually with the power button to reboot. It happens mostly when I am gaming with games such as starcraft 2 but sometimes with Word or Safari.
I have cleared my cache, vacuumed my computer, reinstalled OS X, tried regulating the temperature with smcfan but nothing works. I also took it to futureshop on my warranty and they couldnt help me, nor could multiple Mac Phoneline assistants.
Any solutions?

I added some Crucial Ram to my late '07 iMac (Aluminum, 20", 2.4 ghz),
Apple did some warranty work on it for me, a year or so ago, but.
I jumped up the Ram from 2-4. It's only showing 3 Gb's now.
And, the fans were ALL running at Full Speed! Wow, vacuumed my desk!
Anyway, I came here, and was advised to do several things, but the one that worked,
was 'Resetting the System Managements Controller" SMC.
1 Shut down the computer.
2 Uplug the computer's power cord.
3 Wait fifteen seconds. (HMM, what couldja do?)
4 Attache computer's power cord.
5 Press the power button, to turn computer back on.
I heard a high pitched 'Chong', (Higher than the start up sound), then, the start up sound.
Now, I'm in my comfort zone again!
Dam, if that didn't work wonderfully?!!!
It did!
I hope that this may work for you!
Be well.
PS btw, I still can't get my 2nd stick of Ram to work.
I'm still working on that.
And, my third, Western Dig, 2 TB external HD!
What's with these third party suppliers?
They suck!
Apple has to bring some control back in!
I bought the WD @ a Mac Store, (Cherry Hill, NJ)
The Memory, through Amazon.
Grrrrrrrr!
Hope this works for you, let us know, OK?

IMac freezing but I can move cursor and music continues playing

Hi all, I am having trouble with my iMac freezing. It has done it three times in the last five days. Today, I had Safari and Pages open and was listening to iTunes in the background. I left the room for a couple of minutes and came back, the music was still playing, the clock was frozen, I could move my mouse but could not click on anything.
Yesterday, the same thing happened, I ran disk utility and cleared off some old third party apps that I wasn't using. I noticed improved speed in my browsing and the loading of apps and thought the problem was solved. Now that it has hapened today I am perplexed. Activity monitor doesn't show anythig out of whack. I saved some info from the activity log:

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

7. Launch the built-in 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.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Random screen Freeze, but mouse is responsive

Hi,
For the last month, I have been having random screen freezes , requiring me to hard-boot the computer. During this freeze the mouse is responsive. I wait 15 minutes to see if the freeze goes away before rebooting.
I have re-formatted the disk and installed Mountain Lion, again , but it did not help. Most of the time it seemed to happen when I am using Safari, but this is not always the case.
The hardware tests came clean.
I have isolated the console logs to the following just before the issue happens. Any suggestions on how to proceed?

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, 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.

Late 2013 15" Macbook freezing, but mouse still responsive, any suggestions?

Hi,
I have a new late 2013 Macbook Pro 15" Retina that keeps freezing periodically throughout the day, When it freezes the mouse can still be moved, but nothing else can be clicked on the keyboard commands are non responsive.
I did notice a GPU hang in the system logs. Is anyone else having this issue? Suggest any solutions?
Thanks,

I have had this issue twice so far. The first time it happened when I was exiting Safari, and the second when I was closing the Pixelmator. So it may have something to do with automatic graphics switching. It can be disabled in System Preferences -> Energy Saver, but I haven't yet bothered to try, since it only happened twice and kind of defeats the purpose of having two GPUs. Hope this helps.

My i pod will not play videos they just freeze but they work on itunes

my i pod will not play any videos that i put on but they work fine on i tunes, they play but 1 second in to the video it just frezzes and you can hear anything so what is wrong.

Have yu tried the standard fixes:
- Rest. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
-Restore from backup
- Restore to factory defaults/new iPod

PC keeps freezing but mouse still works...

So my PC keeps crashing, sometimes when I turn it on straight away, sometimes after a few minutes, very rarely it doesn't crash.
However when it crashes, my mouse still works, I can still move it around. Sometimes on Chrome for example I can still click links, but they won't load.
In other apps the PC totally crashes when I click something.
I've tried drivers, firmware updates, it's definitely not overheating. Just cannot work out what the issue is.
I've got an SSD but not had any issues from it but i'm worried it could be this or the motherboard.
The red light on the front of my PC that flashes when my PC is working just goes solid red when it crashes, and the only fix then is a hard reboot. Very frustrating, especially if i'm in the middle of something.
Anyone got any ideas or ways I can test what the issue is?
Thank you,
Liam.
Edit to say i'm on Windows 7.
Edit again to say i've done Chkdsk on my SSD and it seemed OK...

NCN
After the above
I would update the SSD firmware and run windows performance recorder (if you can when you are having the problem) and it does run in win 7.
In order to diagnose your problem you will need to download and install the below
Install the WPT (Windows Performance Toolkit)
http://www.microsoft.com/en-us/download/details.aspx?id=30652
Help with installation (if needed) is here
When you have, open an elevated command prompt and type the following
WPRUI.exe (which is the windows performance recorder) and check off the boxes for the following:
First level triage (if available), CPU usage, Disk IO.
If your problem is not CPU or HD then check off the relevant box/s as well (for example networking or registry) Please configure yours as per the below snip
Click Start
Let it run for 60 secs or more and save the file (it will show you where it is being saved and what the file is called)
Zip the file and upload to us on Onedrive (or any file sharing service) and give us a link to it in your next post.

IMac freeze after startup, works fine in safe mode

Hello, my Mid 2010 iMac is freezing about 3 minutes after startup. Ive tried booting from the instal disk and repairing it but it didnt work. In safe mode it works completely fine. It similar to some other peoples problem but i was hoping someone could help me, my applecare literally just ran out like 3 weeks ago.

Hi baltwo,
Im sorry but Im new to the community and I don't know how to address users directly. Hence intruding.
It would be kind of you to shed some light on the matter.
I'm running lion 10.7.5 and followed similar procedures but mail downloads every mail again after cataloging and indexing my earlier(snow leopard 10.6.5) mail. More details at https://discussions.apple.com/thread/5373643
It would be great to find a solution as I'm struggling since two weeks.
Thanks,

Lion crashes and freezes, but mouse can move.

I have a 15'' MacBook Pro from late 2010. 2.4 Ghz i5 with 4 GB RAM.
I installed Lion the day it came out and I've been experiencing the same weird freezing problem.
I tried to keep track of when it would freeze (as in what apps were open and such) but it has happened in all sorts of conditions. It's frozen probably 6 times now and 4 times were watching a video on full screen safari. One was when I booted from sleep, and another was just in Finder.
I have already reinstalled Lion once (holding Cmd+R at the boot screen), but the issue still happens.
What happens is that the application I'm running (mostly Safari) crashes and goes to the beach ball. When I force quit it, it asks if I want to report the issue (I do) and then after that the system freezes. The odd thing is that I can move my mouse around. Many times I've just force shut down from there. But one time I just pressed the power button and it asked if I wanted to shut down. When that happened, it shut down but stayed at a white screen with a grey loading circle thing (it's moving) and just stayed there for over an hour before I force shut down again.
I was wondering if anyone had the same problem and if anyone knew how I could fix it??
Thanks in advance for your help!

Hi sherwu,
there are several ways to fix this problem described in this thread:
https://discussions.apple.com/thread/3191083?start=0&tstart=0
Having the same issue with the same 15" model the easiest and working fix for me was to deactivate the automatic graphic switching in the energy saving panel in the system preferences.

Desk top froze up but mouse works how do I unfreeze desk top

TRying to in freeze the desk top the mouse will move but can't click on anything and no response from key board

Hold down the Power button for 5-10 seconds until the computer shuts down. Then turn it back on after a few seconds. If it starts up OK I suggest repairing the hard drive and permissions just in case.

Radom Freeze but mouse moves, Netinfo problem?

My problem is that randomly my computer will completely freeze with the exception of mouse movements. I was having this problem before, and tried a fresh install, fresh install with no installed programs, new RAM, old RAM, and now with a newly replaced logic board. The freeze happened again today and the clock stopped at 10:52am and got it back by putting to sleep (which took awhile) and then awakening. Here are the system.log entried around the time the problem occured.

Is there anyway I can disable the netinfo lookup or is this a problem with the network/airport card. Any insight would be greatly appreciated.
macbook Mac OS X (10.4.7)

At long last, I have finally found out what it was.
After Apple had replaced the logic board, processor, and graphics card that Netinfo errors were still continuing. Because I had not reloaded the OS since the hardware had been replaced I figured I would give that another shot.
I got the OS installed and updated, Mac OS X 10.4.9, and ran that for just a little while. No problems at all. A few days later I started to layer on my applications, MS Office, Firefox, Internet Explorer (We still need to test web sites here with IE for Mac because some users still use IE.) After a few days, still no problems. I then started to layer on my utilities, Toast, Growl, McAfee VirusScan.
Everything still worked just fine...for a day. When I came in the next day my computer had locked up again. So I removed the utilities. Everything started working fine at that point. I put the utilities on one at a time and ran each one for several days. I finally got to VirusScan and the error's came back. I removed VirusScan and the errors went away.
The version of McAfee VirusScan I was running is 8.5. Currently I am not running any VirusScan software at the moment. Our network team here is talking to McAfee in regards to this problem. Hopefully a solution will present itself.
