Macbook freezes randomly on Playback in Garageband

After the last Garageband update, my Macbook freezes (Mouse cursor still movable, graphics frozen, keyboard not working, sound still playing) on playback. The project has a quicktime movie (soundtrack project) in it. I already tried different compression modes (JPEG, H-264) for the movie, but that didn't help.
The project worked just fine before the last update. Since then I also updated to the latest perian version. But should that stop the whole computer?
The only way to quit ist forced shutdown.
Thanks in advance for any help.

Thanks for your reply. But all the things mentioned there didn't describe my problem (complete system hang).
I just reverted back to Garageband before the last Update with Time Machine: and it seems to work! I hope Apple fixes whatever is wrong there. Maybe I should have used the downloadable update instead of "Software Update"?!
Glad that it's working again, as I need to finish a project...

MacBook freezes randomly

Hi,
Since yesterday, My MacBook Pro (Early 2011) with OSX Yosemite 10.10.1 freezes randomly.
When the screen freezes, the cursor can’t be moved anymore and the music that’s playing is ’stuttering” (repeating).
I’ve noticed that the freezing happens when I launch programs as Photoshop, Illustrator, iPhoto,…
Each time I open my MacBook Pro and the Mac recovers from Sleep Mode, I can see the login screen but I can’t move the cursor or type in my password anymore.
Is there somebody who knows a solution for this frustrating problem?
I can’t use my Mac longer than 15 minutes anymore.

Macbook Pro random freezing

Hi, I am experiencing random freezing of OSX, First I thought it was related to the latest flash, so I deleted it but the freezing keeps happening. Then I thought it was firefox so I switched to safari 5 but still it freezes.
Now the computer freezes randomly, some times while on the internet, some times while using mail.app, some times just sitting in the finder.
It freezes also every time I try to sync photos to my 3GS in itunes.
It also freezes after Steam is open for a while.
It is a unibody Macbook Pro, 17 inch, early 2009, 2.8 GHz Intel core 2 Duo, 4 GB 1067 MHz DDR3.OSX 10.6.4
If anyone has any ideas how to solve this it'll be much appreciated.

I upgraded my MBP 2009 Unibody from the original 250GB HD to a 500GB 7200rpm HD, only to experience the dreaded freezing. Freezes randomly and shows the Beachball for about 30-60 seconds. So, I put my old drive in for a while. Then later, (about3 months), I got another 500GB 7200rpm drive. Installed it, and same problem. So I put it back like it was after having to delete a bunch of stuff to get it below 250GB so I could continue to use it. Later got a 3rd 500GB 7200RPM Drive and SAME PROBLEM! So, I put a 320GB 7200RPM drive and it ALSO has the same problem.
However, each time I did this, I used Disk Utility to copy the data using the Restore command to the new drive. While connected via USB, the drives all worked great. Put them INSIDE the MBP and they give this problem randomly.
I'm really getting sick of it.
Then on August 19, a "fix" was released as a firmware update. I just found this tonight and when I ran it, I was told "This computer does not need this update." So, I guess it's only for APPLE BRANDED Drives, not my other drives. I've tried Fujitsu, Western Digital, and Hitachi drives and they all give the same problems.
Anyone know what I can do to fix this?

Macbook Pro (mid 2007) freezes randomly

Hi all,
Last week my Macbook pro (2007) started to freeze randomly. 2-3 years ago I added an SSD (64 gb crucial M4) and replaced the dvd drive for an 500 gb HDD. The configuration worked perfectly until last week. My macbook sometimes works for a couple hours and sometimes it freezes just after 30 minutes from startup. Sometimes during an freeze I can use the programs that were open. For example when reading an PDF I can scroll 1-2 pages down/up. When I scroll more than 1-2 pages Preview freezes as well.
I have done the following things to exclude some frequent problems.
Set my fan speed to 6000 rpm to exclude an heat problem. The system freezes also with 'normal' temperatures.
Checked my SDD & HDD on file consistency and repaired the disks with disk utility (booted from Mac Os X install cd). Disk utility reports that the disks are okay. I also checked with Techtool pro on bad blocks and smart status. All seems to be all right.
Checked my RAM with tech tool
Reset NVRAM
Checked console for error messages. There are no messages at all between a couple of minutes before a freeze and a forced turn off/on.
I haven't installed new software recently.
Last time when my macbook froze, I had an terminal window open. In this window I could execute some commands, only the most basic. Top, sudo, shutdown etc. didn't work. I could navigate to all folders on both SDD & HDD. But I couldn't see any files, only folders. That is strange right?
I think the next step is to change the hard drives for an other (new) one, to exclude hard drive problems. But before I open my Macbook I was wondering if anyone has other ideas to solve this problem.
Thanks for any help.

Back up all data immediately as your boot drive may be failing.
If you have more than one user account, these instructions must be carried out as an administrator.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CSeq "I/O error" | tail | open -f -a TextEdit
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application. 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 window will be empty. If you get output like this:
kernel[0] <Debug>: disk0s2: I/O error
the boot drive is failing, or there's some other hardware fault in the storage subsystem.

1 week old macbook pro 17 keeps freezing randomly?

Hi, I just bought a 17 inch 2011 early winter macbook pro a week ago and I upgraded my computer with the lion the second day. My problem started the third day of the purchase i started noticing lag in the beggining especially when i open the appstore the beach ball comes up and won't ever go away.yesterday my computer been freezing randomly i've been restarting it whenever this happens The freezes happen most frequently after the computer has been to sleep and woken up by opening the lid.. I have downloaded all the apple updates and my apps are all up to date I dont have anything on the startup,I have 690 gb free on my hard drive I tried: - deleting apps from running on the startup - no widgets - Stopping Bluetooth and wireless - not opening i tunes Nothing worked. I really don't know what to do,this is the first time i use mac.please help.

I would prefer to have acopy on Lion on a Flash memory or a DVD in order not to redownload it every time again. I guess you didn't take a copy of it after downloading from App Store and proceeded to install directly, right?
Ok, if that was the case,
- Open the App Store again, click on purchased icon on the top, you will find the Lion as installed..
- Click on purchased again while holding down options key (alt), the INSTALLED botton will be replaced by INSTALL botton.
- Click it and wait untill in downloads againg.
- After finishing download don't proceed in installing it again using the wisard. Quit the installer and go to the Applications folder, find "Install Mac OS X Lion.app", right click and select show packge contents and go to "/Contents/SharedSupport/installESD.dmg".
This is the image disk of Lion, use Disk Utility "Spotlight it" to burn it on a DVD so will have a bootable DVD which can be used to reinstall your autherized copy of lion.
- Restart your machine while holding Options key to get the boot options.
- Select the DVD, a Disk utility will appear again, use it to erase the Macintosh HD and reinstall Lion again

My macbook constantly freezes randomly? please help!!!!!!!!!!!

I have tried virtually everything I could. Repairing disk utility, resetting PRAM. Whenever the freeze happens all I can do is resort to forcefully shutting it down. To be more detailed, at startup I ussually hear my macbook getting louder than ussual. I even erased everything I had on the disk and It would still freeze randomly. (of course I backed everything up) I am at a loss at what to do I even struggle with connecting to the internet on it. Would upgrading to os lion resolve this?

Upgrading will not help. First you must resolve the cause of the problem. Since you have a current backup do the following:
Drive Preparation
1. Boot from your OS X Installer Disc. 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.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
When the process has completed do a fresh install of OS X. Before you restore anything from your backup check out the new system to be sure you no longer have problems. If you continue having problems then most likely there's a hardware issue. You may have defective or marginal RAM. You could try removing the RAM, clean the contacts on the edge card using a clean pencil eraser. Then reseat the RAM.
You can also try Intel-based Macs: Resetting the System Management Controller (SMC)

MacBook Pro Random Freeze

I have a 15" 2.66 GHz Intel Core 2 Duo MacBook Pro with 4 GB RAM and a 320 GB HD.
My MacBook Pro was working fine until several months ago it started freezing randomly. It would freeze during normal use of the computer and would be completely unresponsive for a couple seconds to a couple minutes. Sometimes, I had to force restart. The frequency of the freezes increased, and one day, it just wouldn't boot to OS X. It was really strange, since I had Windows on the laptop using Bootcamp, and that would work. When I tried to restore using my Time Machine, it froze after an hour. I tried it a couple times using different versions and all versions froze. I had to a fresh install, and migrated my data using Migration Assistant. For a couple weeks, the computer ran fine. However, one random day, the original problem started up again. The frequency increased, and this time I took it to the Apple Store. They created a new user account, and it didn't seem to have the problem. I moved all my files from the old user to the new (copy & pasting). The problem disappeared, but reappeared like usual after a few weeks. I took it back to the Apple Store again, and they changed the hard drive. After I had moved my files over, I noticed the computer freezes randomly.
I thought maybe my iTunes Library or iPhoto Library were corrupted, so I moved them to the Desktop. iTunes and iPhoto created new folders in the respective Music and Pictures folder but the problem persisted. I have no idea what's causing the problem, and its EXTREMELY frustrating. Its very difficult to work on this computer.
I tried all the major debugging methods: repairing file permissions, repairing file permissions on the home folder, fsck, etc. Everything seems to be in proper order.
Any help is greatly appreciated.

I am facing the same problem. Look at this thread and lets start ruling out by deduction: http://discussions.apple.com/thread.jspa?threadID=2513205&tstart=0

17" Macbook Pro late 2011 freezing randomly

Lately my 17" Macbook Pro (October 2011) has been freezing randomly. At first I thought the cause was high-usage applications, but apparently not. It's been freezing when I read something on reddit, when I'm on Facebook, when I open Photo Booth, or (the latest freeze) when I'm typing something in Text Edit.
When it froze and refused to boot back up (it got stuck on a grey screen, and I also got a vertical lined blue screen), I took it in. The repair guys figured it was the logic board, so they replaced it and the battery too.
Now tonight I just got it back, and it froze AGAIN. I was able to boot it back up (I had to do a hard boot), and it went to the login screen fine. However, when it got to the login screen, the fans started working overtime like crazy. My computer was vibrating, I could feel it in my fingers as I typed in my login info. Once everything was loaded, the fans slowed down pretty quick, and it's as quiet as a lamb right now.
Could this be a heat issue? Or maybe something to do with the hard drive? The vents were clear when booting, I didn't think to check the air though.
It's got two months of warranty left, would they take it in? I can't forcefully make it freeze (it happens randomly), so I can't really show them any proof.

You've the issue as discussed in this -> https://discussions.apple.com/thread/4766577?tstart=0 thread.
It's a problem with the way the GPU was soldered onto 15" and 17" machines. It's not everyone who suffers the same problem, but your symptoms match the same problem to a "t."
Read over some of the article and you'll see that you're not alone. Apple's 'fix' for the problem is to sell you a new logic board, but they can continue to fail one after the other. The only true 'fix' (and we'll just have to wait and see just how long these fixes work) is to have the GPU reballed onto the logic board.
Good luck,
Clinton

After Update Mac OS 10.6.5 my macbook freeze

Immediately after updated to release 10.6.5 I encountered the following problem that occurs at least 3-4 votle day and apparently when I put my Macbook Pro under stress (quickly move windows, view many youtube videos, and any kind of excessive load on the machine): the screen freezes with all the windows blocked, and I can only move the the mouse cursor. To solve the problem I turn off the machine while holding down the power button!
The Apple Hardware Test found no hardware problem and it is strange that these problems occurred immediately after upgrading the operating system.
Please, How can I fix this? Does anyone have my same problem?
Thanks!

Do you think it's a hardware problem?
I don't think because it's occured immediately after the update and because it's the same problem of these threads:
- System Freezes Randomly after 10.6.3 Update (http://discussions.apple.com/thread.jspa?threadID=2383288&tstart=30)
- System freezes after 10.6.5 update (http://discussions.apple.com/thread.jspa?threadID=2650373&tstart=0)

Random video playback

Hi,
I have posted this request for the past couple of years. I am amazed that some simple program cannot do the following -
Play video clips in random order. That's it. That is all it has to do.
iTunes will allow you to play a list of videos but only in order from top to bottom. If you try shuffle it freezes. I've talked to Apple techs about this too and other third party vendors like Boinx. Random video playbacks are not featured in any program out there for all I know.
It would be nice too if the program could equalize the sound level too from video to video - that's all it would have to do.
Is there a reason why this is so hard to do? I have a mac mini attached to a Apple Cinema and I like to show video clips from Vimeo and other places but not always in the same stale order from top to bottom. Yes I can drag and re-order the playlist, but sure would be nice to have it all done randomly and to keep a constant volume level from video to video.
thanks - if you have any ideas or can help
I think a random video playback feature would be neat in iTunes or Front Row or am I the only guy that digs this? I could be since third party developers are not harkening to this calling.

I've never had any issue using the shuffle feature in iTunes to play videos in random order. You might try creating another user account to see if it is a permission issue. If it's not, you might want to reload the latest version of iTunes on your computer.

Macbook freeze after Lion

My Macbook Pro freezes every now and again, especially when using Safari. This happens after an upgrade to Lion.
When I pop out the forced stopping window and give it the command to stop Safari, that window to freezes.
Mouse pointer still moved though, but can't select anything outside the frozen window's scope.
Safari was not running full-screen this time, so the link I suggestede earlier is not confirmed.
Hope This Helps in solving the issue.

I am having the same problem except I get the pinwheel and cant do anything, it just freezes randomly. However mine freezes upon reboots if i do not leave that box checked that says to reopen windows. I have to hold the power button down to shut it down then it will come back up ok. I hope they fix this with a patch soon especially since I had 0 problems before the upgrade

PowerBook G4 freezing randomly

My PowerBook G4 (1.67) has worked flawlessly for 2 years, but just a few days ago it began freezing randomly. It freezes completely, without warning or slowdown. I have to shut it off manually each time. Sometimes it freezes after running only a few minutes, other times it freezes after several hours of normal workload.
It doesn't seem to be related to anything I'm doing at the time, as each time it has been different circumstances. The last time it was idle with only iTunes running.
I am running OS 10.4.9, but the problem began before I installed the OS X update, so I know that is not the cause.
Is there anything I can do to further troubleshoot the problem before sending it in? Any clues as to what might be causing this?
Specs:

Welcome to Apple Discussions, BPMayer.
Apart from what has already been suggested by joeuu, it is possible that your problem may be either hard drive or logic board related. Certainly something to test for and, hopefully, rule out.
Therefore the first thing I would recommend is that you make sure any important data is fully backed up immediately. If you don't have an external backup drive (preferably a FireWire drive), then this is a very good time to get one.
Next try restarting from the original installer disc and then using Disk Utility to check the state of the hard drive. At the same time see what the SMART status (located at the bottom of the DU window) says. If it says anything other than "Verified" then the hard drive is the source of the problems.
Another thing to try is the Apple Hardware Test. This may reveal any problems with the internal hardware.
Unfortunately hard drive failures can, and do, happen fairly often with any computer that uses one as a storage device. Therefore it is a problem that can afflict any brand of computer, not just restricted to Apple, and (unfortunately) seems to be much more prevalent nowadays.
Fortunately, providing you have your important data backed up, it is not too traumatic and replacing them is not overly expensive (when compared to other major component failures).
Logic board failures can occur but, thankfully, appears to be rarer than drive failures. Whilst they can be expensive to replace, your data should not be at risk (unlike with a drive failure).
