PowerPC :: G4 Locked Up - Cannot Restart After Shut Down
Jan 26, 2009
My PowerBook G4 15" alu 1.25 ghz locked up out of nowhere the other night (while only running firefox). Couldn't even force quit, so after a long wait I manually shut it down. Then I couldn't get it going again. I pulled the battery, let it sit overnight, and then it started up, only to freeze up again in 30 minutes. Same routine yesterday (though it lasted an hour or so).
I live in Germany and the only Apple store is hours away. And of course my Apple Care is expired. I've zapped the PRAM, reset the PMU, ran first aid on disk utilities (everything came back OK), but I'm freaking out. This thing is seriously important to me, and I can't afford to replace it. I've read plenty of speculation that it could be the logic board, or that it's locking up from overheating, or maybe the hard drive is going bad (though the tests come back OK).

I have an iBook G4 (1.25g memory and 1ghz processor) running Tiger. I have never had any problems with my iBook in the past and now it seems the second my warranty expires I do. I was using it earlier today and the entire thing just locked up for the first time ever and little lines started appearing on the screen. I turned it off and rebooted it and it froze on the Grey screen, I repeated and it keeps doing the same things. It actually loaded a few times and then promptly froze. I tried booting from the CD and it freezes right on the screen to select your language (if it gets that far).
I went into applejack/single user (which runs fine) and repaired disk/repaired permissions/cleaned up system files/ and cleaned up virtual memory. I also used the fsck -y check disk which I'm assuming is the same as typing in 'applejack' and then selecting 1 (But I thought I would use it anyway). The first time I ran fsck it said it changed a system file. I then ran it again and it said that the HD seemed okay. Assuming that fixed the problem I restarted my computer and it froze...again. Or is there a way to reformat from single user?

My early 08 MBP has seemed to have lost the ability to do the above 3 functions. Pressing the power button does not bring up the shut down/restart/sleep menu and going through the menu bar and clicking "shut down" does nothing either. Pressing cmd + shift + Q does nothing when it used to bring up the log out option. It's only been like this the past few days, I noticed when I was prompted to reboot for the SMC update but OSX did nothing after I clicked the reboot button. The only way to shut down or reboot is to perform a forced shut down.
I've repaired disk permissions, repaired the disk, reset the SMC and the PRAM but nothing has worked.

Finder is refusing to let me shut down my macbook.Â
I have tried multiple ways to try and get my mac book pro to shut down, but every time finder pops up and tells me that "there are operations still running, quit them and then try again" something along those lines. I've tried to end processes in the activity moniter, I've done the command + option + escape and the window pops up and shows there is nothing running. I've also tried to hold down the power button for 7 seconds and it still says I am unable to shut down my computer because there are processes still running.
I really don't want my computer battery fried by having it on all day, every day. Â

I'm running a 2007 silver Imac and just upgraded to SL. Aside from all my apple aps (ie. logic pro studio 8) running slower than molasses rolling up a hill. My mighty mouse (wired) jumping to the corner of the screen all the time and WiFi won't stay connected to my router for more than a few hours at a time (when this happens it also likes to ask me for the password it already knows and rejects it when i reenter it?
And my computer won't shut down or restart? I read in another thread about this happening with multiple accounts and a log out being needed but I don't have other accounts. So I have nothing to log out from? I'm super disappointed and am tempted to switch to windows 7, but I've already invested a small fortune into my apple and apple exclusive software like the looser that I am. And you'll be saving a perfectly good computer from being thrown out the window.

I've been happily in love with my iMac since 2006. Never had any problems.
Just got back from working abroad over a month and my business partner (new to Mac) has been using my computer. Apparently the computer was switched on nearly 24/7 and only been restarted a couple of times.
At first everything seemed fine until I ran the software update.
First problem, there was an error when doing the security update so couldn't complete the whole update.
iMac still working fine though..
First, it took ages to startup, then the dock didn't load. Tried restarting at first, didn't respond, shutting down neither....
Then when opening finder, the menus on the left hand side, Hard Drive, Documents, Music, etc... all gone...
Most applications won't open... even some jpegs, pdfs, etc...
Also the DiskImageMounter, Terminal and probably loads of other stuff has disappeared I'm not even aware of...
Tried to open 'About this Mac'... no response...
Tried to open.. 'Mac OSX Software' the following message appeared... Your system settings are being updated. Unable to open your preferred Web browser. Try again in a few minutes.
I've looked at the utilities folder, checked the CoreServices, tried 'killall Dock' (discovered that the terminal utility disappeared), etc, etc.

I have a 15" MacBook Pro unibody, when I click shut down, to turn it off, it just restarts! It doesn't shut down. The only way to turn it off is to hold down the power button for a few seconds. Even then, sometimes when I do that, it will randomly power up without touching it at all.

SOME ago, I came across a strange problem on my macbook pro: I wast able to log out, restart or shut down using the apple menu, nor using the power button, which just won't respond.When I try to restart, nothing just happens. No spinning wheel, nothing. The only way to restart is to use sudo reboot in the Terminal.This problem started short after I installed a program called FontForge, but uninstalling it didnt help, nor did recovering the system from an older Time Machine backup (from the time before I installed the FontForge). Finaly I thought it could be something about the SMC and I reseted both it and the PRAM, but without any success. Then I did a re-installation of Mac OS X Lion using Lion recovery, but still no difference and now Im beginning to feel quite clueless.

My iMac 27inch, Mid 2010 2.93 ghz i7 running Mac OS X Lion 10.7.3, doesn't shut down or restart properly. Once I choose the option in apple menu it goes into white screen with a wheel spinning, it freezes there. The only to proceed is by manually holding the power button. Checked and repaired all disk permissions in standard and recovery mode, reset PRAM and SMC, did couple of cleaning procedures of cache and relative, did a whole virus running procedure. Cant figure out what has happened. It happens after I operate computer after turning it on, but it does shutdown and restart if its done straight away after turning it on without opening anything. I tried to monitor maybe it some software that makes act like that, but didn't find a link.

I am running a Macbook Pro using OSX Snow Leopard 10.6.8.Â
For the past few days, I am completely unable to restart or shut down the system, unless I hold down the power button.Â
I have checked Disk Utility -> Verify, and it says my HD is fine. I don't know what else I can do?!

Ever since I have upgraded to Lion from Snow Leopard, sometimes MacBook Pro doesn't shutdown or restart. I choose shutdown or restart it logs me out then there is the gray screen with the turning little dotted circle and it doesn't reboot or turn off, so I have to hold the power button and manually turn it off.

I often have an issue where my iMac won't shut down, restart or logout users. Basically, when I click Shut Down or Restart, the desktop icons disappear as if the computer's getting ready to shut down (the desktop wallpaper remains) and it just sits there and won't shut down. I have to hold down the power button on the back of the computer in order to get the computer to shut off. This often happens when I try to logout a user. I'd say this happens about 2/3 to 3/4 of my attempts to shut down or logout a user.

I downloaded Mac OS X 10.5.7 from the Apple website rather than using Software Update only to save time. I used Software Update to get 10.5.7 on my MacBook Pro and it took 35 minutes to download the package. Using the Apple website for my iMac, the download took about 15 minutes.
I then began the installation of 10.5.7 on the iMac. Everything went fine until it was time to restart. The computer froze on restart. I had to hold down the power button to turn off the iMac. Then I started it up and it began to load for quite a while (normal after an update). Then I logged in and went to "About This Mac" and it read that I had Mac OS X 10.5.7.
Obviously, this is an unorthodox way of updating. But am I safe with this method? Was it just a minor glitch?

When I select Restart or Shut Down from the Apple menu, all of my apps close, but then it just sits there showing the desktop pattern. The cursor remains live. Nothing else happens. I have to hit ctrl-opt-power to force a power down.
This happens regardless of which account I'm logged into. (I have an extra "safety" account that I never use for anything. It has admin privileges.)
It also happens if I click Restart or Shut Down in the Login screen.
It also happens if I force reboot into Safe Mode and then try to Restart or Shut Down.
This iBook (see sig below) has a brand new HD in it, and I just spent an entire day doing a fresh reinstall of Tiger and all of my apps.

I have an iMac running 10.7.3 that will not shut down or restart using the apple menu. The only way to get this machine to shut down is to hold down the on/off button on the back of the computer. This has been a problem for quite some time and may have started with Lion, but I’m not sure. .

While working on my iMac, it suddenly went off. No warning at all. I've tried all the basic stuff and nothing happens. Holding the power button in and I don't hear the normal sounds. Thought it might have overheated but after it's cooled down, still nothing.

After "upgrading" to Lion, my MacPro refuses to complete either a Restart or Shut Down cycle. How can I discover what is hanging up the process? System: MacPro1,1; 8GB RAM, OS X 10.7.3, 4x2TB internal drives, all software updates applied. Â

In Lion, when restarting, many apps restart as well and open up many docs, slowing startup with stuff I don't want. I have unchecked the "restore windows when quitting and re-starting" box in system preferences>general. There has been no effect. Now what?

I have a macbook pro mid 2012 non-retina (2.6 GHz Intel core I7 processor, 8 GB 1600 MHz DDR3) . I installed mavericks 10.9.4 and windows 7 through bootcamp. Almost every time I have to restart the computer, in order to use Windows, it just takes forever to do so. It is permanently stuck in the grey screen with the loading icon and eventually I have to shut it down manually.

so i've been having an issue with the double tap to hi-light any text i wish to copy. Such things as double tapping the URL bar to hi-light the whole url so i can just retype w/e site i want to go to. Every time i restart or turn off or my mbp goes to sleep and i reopen it, the double tap function resets. So i'm forced to go to the system preferences > trackpad> "double-click speed" to slowest in order to get my double tap to hi-light anything again. Is there something wrong with my mbp? Or is there a way i can save the settings when i put the double-click speed to slow so that it wont reset every time my mbp needs to be woken up or restarted?

My imac will not shut off/restart or let me download the new updates because it says I have to quit the TextEdit first, but it will not let quit it. When I open up the TextEdit the Quit option is in a faded black/Grey color and does not do anything when I click on it.

I accidentally connected my wife's MacBook Air to my docking station at work today. Nothing seemed to happen so I undocked it and the computer displayed a black screen and I could see and move the cursor using the trackpad. I then tried shutting down by holding the power button for 5 seconds, 10 seconds, 1 min, etc. Nothing worked and it's stuck on the black screen so I can't use Yosemite's menu to shut down or restart. When I leave the computer idle for around a minute, the cursor disappears but it will reappear after pressing keys on the keyboard.

Thought the house power had gone off because when I returned home, my Mac was off. Rebooted checked email, and went to get breakfast. Came back fan running very fast, and machine is locked and no video. Turned off by holding in power button. Same thing happens when I left again. I have now been on the machine for over an hour and no problems. What is causing this?

I use an external hard drive for Time Machine backups and to store some larger video files in a folder called Videos. The Videos folder on the external drive is now locked and I can't unlock it. I go to Get Info, hit the lock icon and enter my password, but the "Locked" checkbox is greyed out in the General section. In the Sharing and Permissions section, instead of displaying my name, it says "Fetching . . ." and I can't change the Privilege from "Write Only".Â

I can't seem to edit any pictures with Preview anymore since I upgraded to Lion. Every time I try to save an image after resizing or whatever, it says the file is locked. If I check the info of the file the "locked" checkmark is unchecked. And I have all the permissions to the file. Tried everything, switched the "lock after 2 weeks" thing of in Time Machine (even though tha would probably not help: images I took today are still "locked" in Preview), tried copying them and then saving them, and tried to lock them and then unlock them, but I can't seem to edit and save them.
