Mac Pro Hangs / Freezes

Jun 23, 2012

I have a 2009 8-core running Lion. It has now starting hanging (desktop visible but no response to any input device). I have run Disk Utility and Apple Hardware Test from install DVD (full test) and it finds no issues. Any thoughts as to how to investigate further. Sounds like a memory leak in an app somewhere, but none are left runnIng.Machine is ok when being used but then is hung when left for a few hours. If I take to Genius Bar I assume they will run AHT and say no faults can be found.

OS X :: Snow Leopard Freezes - Hangs And Unusable

May 5, 2010

I have a unibody Macbook Pro running OSX 10.6.3. Everything is up to date but the computer is now on its second hard drive and fresh install of OSX and is still unusable. After the hard drive was replaced, it worked flawlessly for an evening. However, the old symptoms reemerged the next morning. Symptoms: very slow to boot or freezes on gray screen with status circle frozen grey circle with slash through it on boot

once it boots, if it does boot, the beachball constantly spins/freezes... I have literally no software installed on the fresh install and it still does it when attempting to boot in safe mode Also, the hard drive when checked gives the following errors even after I repair them in drive genius (the same errors the old drive reported):

invalid file count
invalid directory count

OS X :: Snow Leopard Freezes - Crashes - System Hangs

Dec 7, 2009

A few months ago I had a problem with my Macbook Pro, (late 2009 model, 15" 2.53 ghz) that many users with Snow Leopard have, the random 30 second freezes. I simply reset the PRAM and SMC and I never encountered it again. Now, out of the blue, on Sunday (yesterday), I started experiencing these hangs again, but worse. The night before I had been browsing the web and my battery went to reserve and shut down, so I plugged it in and when I awoke and turned it on I started experiencing problems. I figured I would try the same fix, and it almost seemed to make the problem worse. Now if I shut down the computer via "apple -> shut down", then turn it back on and log in etc., from the first few seconds the machine hangs. If I open a folder I get the immediate beach-ball and the machine is un-responsive for anywhere from 1 minute - 5+ minutes.

I have read a lot of fixes for this problem, but most of the people's problems resulted from using Safari or Spotlight. I strictly use Firefox and very rarely even open Safari, and I think I've used Spotlight maybe 3 times total, none in the past few months. So far the things I've tried are:

- Reset PRAM
- Reset SMC
- Run Disc Utility and verify, repair etc. (from SL install disc)

So I'm wondering right now what can I do? Its finals week right now and im in college so wiping my HD is not an option. I feel like there is just something hanging the computer but I can't find the culprit.

Hardware :: System Freezes Or Hangs On Boot / Startup

Apr 27, 2008

I have a mac pro running leopard (purchased in 2/08) and it was running beautifully for almost 2 months with no hangs, crashes or freezes. Then, for some reason, today when I turned it on, it would not boot. It would get to the apple logo, then just sit there for a few minutes, then reboot itself and the same thing would happen. I pulled out the ethernet cable, unplugged all usb except keyboard/mouse and it would then (sometimes) boot into the system, log me in and present me with the UI.

I then quickly performed a soft reboot and it would get to the desktop. However, I can only use it for anywhere from 30 seconds to 5 minutes before it would completely lockup. The clock freezes, the mouse freezes and it just sits there forever. I have tried booting into Vista (BootCamp) and it also freezes before startup is complete. If I hold down Option and then select the System disk, it will either just hang forever or get to the desktop and then freeze again....................

Mac Pro :: Mix Of Freezes / Hangs And Weird Graphical Artifacts Showing Up On Screens

Jul 1, 2012

I own two Intel-era Mac Pros, one at work, the other at home office.couple months ago both started having the same problem: a mix of freezes/hangs and weird graphical artifacts showing up on the screens.Usually I need to reboot. Usually a reboot fixes the problem for a while until it recurs. If it was just one computer, I'd figure disk problem or graphics card.But the fact that both have been affected at the same time makes me suspect some software issue or possibly a trojan/virus.

OS X :: Apple Grey Screen And Hangs, Gets To The Login Screen And Hangs?

Jul 13, 2010

I have a much loved ibook G4 14" (late 2004??). It has just died. Well, in so much as it won't boot up. The ibook either gets as far as the apple grey screen and hangs, gets to the login screen and hangs, actually loads up finder etc and hangs or none of the above. Sometimes flashing red, blue green black.

After lots of research online over the past few days I tried the following: I have tried safe mode (not working), starting the command prompt screen (single user and verbose modes), started open firmware, and tried booting from a CD. Nothing works as the boot gets so far then hangs. I have flashed the PRam, resetted the NVRam, and have stopped short of opening up the case to dismantle it!

I just really want to access the hard drive now. I have tried Target disk mode and linked the ibook (pressing T) via firewire to a PowerPC G5, but the G5 doesn't recognise the ibook. System profiler on the G5 shows the target mode connected and working fine via firewire, just the icon for the ibook/target doesnt mount on the G5 desktop so I cant access it.Currently the boot freezes within a couple of minutes.I tried the hardware test CD that came with the ibook years ago, I have also tried booting from an OSX Panther CD. I'm assuming they would be bootable.

I forgot to mention that in linking with the G5 in target mode, a disk that I put in the ibook drive appeared on the G5 desktop as an external drive, therefore I wonder why i cannot see the actual ibook drive mounted. The CD drive works as it mounted on the G5.Does the ibook have an actual PRam battery that can be replaced? Maybe this is an issue?Am I able to actually remove the hard-drive and access it as an external drive somehow?

Mac Mini :: Mac Hangs On File Open, Mac Hangs On File Open?

Apr 2, 2012

I am using Stata, a statistical analysis program.  Recently, when I try to open a file, using File Open, the program hangs and I have to force it to quit.  I can open files easily if I use Recent files.  When the file gets open, I can do everything I should be able to do with the program.  Analysis, graphics, etc.  It is JUST when I do File Open that it hangs, and it seems to be ONLY with Stata.

OS X :: Leopard Hangs On Shutdown

Oct 29, 2007

I have a MacBook Pro 2.16 C2D that I just updated with Leopard. I noticed that occasionally the computer will hang when I attempt a shutdown. I didn't have this problem with Tiger so I assume it's a bug in Leopard. When I try a normal shutdown all I see is my desktop wallpaper and that little circular animated icon. I have to hold in the power button to force a shutdown.

OS X :: 10.5.6 Hangs While Configuring Installation

Dec 16, 2008

Early in the upgrade progress bar, where it says: "Configuring Installation", with less than 3 or 4mm of progress on the progress bar (18" screen, 1280x1024), it just hangs. It sits there and does nothing more. Both on my PowerMac G5 and my brand new Mac mini. If I wait for forever, and then power down, and restart, it starts right back up in to 10.5.5, and software update will tell me it wants to install 10.5.6.

OS X :: MBP Hangs After Coming Out Of Screensaver

Feb 13, 2009

I've got my MBP running the iTunes cover art as the screen saver, and to lock the computer when it goes into the screen saver. Every once and awhile, it'll hang when I try to bring it out of the screen saver to put my password in. The screensaver will be playing, then I wiggle the mouse, and the screen goes black, as it does normally followed by the username/password box.

But that box never shows up, just the cursor and a black screen. It's not every single time either, kinda intermittent. I've had to do a hard power down to get out of it, unfortunately. This doesn't cause any file corruption, does it? Anyway I've now set my firewall to allow incoming SSH connections only from my user, so that at least I can SSH into it from my iPod Touch, should it happen again.

OS X :: Mini Hangs On Startup

Aug 19, 2009

I was downloading a couple of software upgrades onto my Mini -- the latest version of Safari and a security app of some sort -- when I suddenly lost power. On getting the electricity flowing again, I retstarted the Mini, but it's hung on the opening gray Apple display -- the spinny thing just keeps on spinning, and I get the feeling it's not going to stop. Did the power outage in mid-upgrade screw my Mini beyond all un-screwing? Should I try putting it in Target mode and running Disk Utility on it from my iBook? What should I do?

OS X :: Safari Hangs On Certain Websites

Oct 1, 2009

MacBook hangs on certain websites (yahoo mail, cbs sports, mens fraternity) but only from one of my wireless networks. PC works flawlessly on this situation and macbook works flawlessly on my first wireless router so the problem is tied to the interaction between my Macbook and the second wireless router. I've searched the forums and tried many fixes already that have been posted here or elsewhere: Reset Safari (it then allows me to reach yahoo mail once, hangs on every try thereafter). Go to Safari preferences and uncheck the box for warning of fraudulent sites (no change) Go to advanced settings and input DNS numbers from my ISP (this solved the problem for some websites but not others) try firefox (same problem as safari) software update everything (no help) install onyx (about to do that). network is a DSL modem connected to the first wireless router (DLINK N+). Second wireless router is linksys G (the problem child) and it is hardwire connected to first wireless router.

OS X :: Installation DVD Hangs Then Quits

Oct 13, 2009

I recently bought a used Macbook Pro (A1212). I received it with no battery (on the way), and a dead harddrive (booted to folder question mark). I replaced the hard drive with a new one and tried booting up the DVD. When pressing option during startup, I'm given the option to boot the dvd. I click on it and I can hear the DVD whirr for a couple minutes, apple logo shows up, then a loading circle on the bottom of it, eventually the logo turns into a Deny Circle. What could this mean? The DVD is in tip top condition.

OS X :: Dock Hangs / Unresponsive After SL Installation

Sep 6, 2009

I have upgraded 4 macs (iMac 24"; MBP 17 and MBP 15 and iBook) for 10 days+. Now MBP 17 (4GB RAM) having serious issues with DOCK; Expose and Spaces.
- Dock hangs when I try to open Mail then disappears until I reboot.
- Expose and Spaces do not work -have had to swtich them off as they lose all their settings.
Reinstalled from scratch and everything was well for 3 days now back to same problems.
- Also in Dock preference setting. I cannot activate "Automatically Hide and Show". The setting will not activate at all.
- Command (Apple) + Tab = Application Switcher will not work!
So without the Dock, I have to go to Applications (in Finder) or Recent Items to launch apps! All 4 machines I upgrade are similar except for CPU, RAM and Hard-disk size. Running same apps (except for Aperature on MBP 17 on the culprit machine!)

Software :: Safari Hangs At Startup

Mar 13, 2009

Unexpected power loss while browsing with Safari V4.0Beta (unrelated problem) left me in a state where I can no longer run any version of Safari. I have already restored (via time machine)my entire Library twice with no effect. Other users on this iMac G5 can run Safari with no problem. This appears to be some form of intentional lock out... Somewhat like a parent lock, but parental controls are not being used. In addition, this is the only admin account (I'm the primary user) so I don't make a habit of telling myself I can't use an application. Bottom line: When I invoke Safari, the URL never changes and I am stuck with the spinning colorwheel and an empty white Safari screen.

OS X :: IMac Won't Start Up - Finder Hangs Up

Sep 28, 2010

I was working on my iMac (last year's model) today and the finder hung up (beach ball spinning). I force quit the finder, but it then refused to relaunch (although I could use other programs as before). I then tried to restart the computer but couldn't, and had to force the power off by holding the power button for a few seconds. Now when the computer starts up, it gets to the point where the "loading wheel" (with external spokes) starts turning, but then this "wheel" freezes. I put in my TechTool Pro 5 disc to start it up from that, but the same thing happens (yes, I have been holding down "C" when it starts to make sure that it uses it as a start-up disc). I am at a total loss, and live far from any computer repair store.

Mac Pro :: Superdrive - Hangs While Trying To Read Disc

Oct 22, 2010

I am having an issue where the superdrive in my BRAND NEW mac pro isn't working correctly. It doesn't read DVD's consistently, System profiler hangs when you click on disc burning and after that the drive does not respond to eject commands. When you do get the tray to open, insert a DVD that is a known good disc, it will "mount" on the desktop then when you click on it, it hangs trying to read the disc. When you right click and select eject, the icon just goes away and the disc does not eject. A restart at least allows me to eject the disc. Resetting SMC has no effect on the drives behaviour. Or suggest a good aftermarket DVD drive?
