OS X :: G4 Freezing About 15 Seconds After Each Restart
Sep 30, 2009
I just brought my computer from work to my home and now it's freezing. The G4 running osx 10.4.. freezes about 15 seconds after each restart. The screen is still active but mouse/keyboard is frozen. If it is kept on after a few minutes the computer starts to get very loud, with all the fans working overtime.
I've tried opening it and making sure everything is seated and plugged in well.
Tried different mouse and keyboard.
Tried running disk permissions.
Tried starting to run scripts but can't get to then before the comp freezes.
Tried safe mode but it still freezes too.
Any ideas or do i need to go back to the office and get the restore disk and start over reinstalling anything?

My Macbook Pro has been freezing frequently for about 30-45 seconds at a time. The screen will freeze, sound will stop, but the color wheel will spin and i can move it around with the trackpad. I don't know what is causing this/any possible fixes to my problem. I purchased the macbook pro in mid 2009 and it has OS X lion 10.7.3 installed on it.

I am on the latest version of Mavericks, with all updates installed. My 2009 MacBook Pro freezes a little bit after airport turns on. This would appear to also carry over to when the computer is starting up because when I am able to turn and keep airport off the computer never freezes during startup. Less than 3 moths ago I had Bly airport card replaced so I doubt that the problem is with the hardware.
Except for this one issue, my computer is running perfectly fine. The problem has persisted with a clean reinstall of OS Mavericks. It'd be happy to rely on an Ethernet cable, but that won't be possible in the near future, at least not without lots of wires running across the floor.

My 2011 21.5 inch iMac keeps freezing. Strangely, the trackpad works but nothing on the screen reacts to moving the cursor around or clicking anywhere. requiring a restart (using the power button on the back).
When I then restart, I get an immediate error message saying "A graphics problem has been detected" and enables me to report the problem, which I do.
However, this happens several times a day and only since an upgrade to Yosemite and I have tried a software update.

In the last few weeks my Macbook has started be begin freezing at seemingly random intervals. It is a 2008 Macbook, not a Macbook Pro or Macbook Air. At first this was only once a day, or once every other day, but it has gotten progressively worse. By today, I can't go more than 2 or 3 hours without it freezing, forcing me to manually restart the computer. The freezing is not application specific; once it freezes with one application, if I try to pull up anything on the menu bar, the menu bar proceeds to freeze. I haven't made any recent major changes to the computer, and it had been working perfectly fine before now. I'm working on scanning it in case it is a virus, but this is seeming increasingly unlikely.

So I even followed some tips from a previous discussion up here somewhere in this forum and still haven't succeeded.... When I tried the Option key at the startup chime, I got an padlock icon and underneath it there was a box like to enter a pass code with an right arrow tab next to it...

I am using a Mac Mini with a Realtek USB wireless dongle to connect to the internet. The software and drivers appear connected perfectly and i see the wireless utility and I can access my wireless network, which says signal strength 100%. I connect to it and it accepts the wireless key. Says connected. Then after a few seconds the connection is lost and it says 'Disconnected'. A few seconds later it connects then disconnects and this continues indefinitely but Safari never allows me to access any webpages.

I restarted my computer, and when it booted back up the clock was reset to Dec 31 2000. I did not change the clock, and my control settings are password locked.
Should I be concerned about this, and has this happened to anybody else?

I have a DP 2.5GHz PowerPC G5 which is giving me problems. It is on all the time (server). If I try and restart it switches off but will not restar. Also, if it crashes (only happens once every few months) then it will not automatically restart. I have replaced the internal battery but this has not helped. I have also reset the PMU. Any ideas what may be going on here?

I have just shipped my Mac Mini to its new home and I've had reports that the panic error is appearing on boot up: "You need to restart your computer. Hold down the power button for several seconds or press the Restart Button." This screen appears on the blue window just after the grey apple screen has disappeared and does not get as far as the desktop at the same point each time. We have tried to reinstall mac OS from the original install disk but holding the "C" Key or the "Option" Key down on restart doesn't boot from disc. Is there a way you can view the Kernel Panic log before you boot into Mac OS so we can try and pin point the source of this problem. I'm wondering if this could have been the result of the shipping that has caused some hardware to come loose.

This is a problem I've noticed on two Macs I currently own. First I had my 20" iMac with Vista installed, and currently I have a 24" iMac with XP installed. In both cases, when I'm in Windows and need to restart (for whatever reason) and want to go back into Windows instead of OS X, the Option key does not function correctly to bring up the OS select screen, and instead will go straight to OS X, as that is the default OS I have set up to boot into.
So basically, if I restart from OS X, the Option key works fine and I can choose to go into Windows, but restart from Windows and I have no choice in the matter, it makes me go into OS X. Any idea why?
My first thought is that it has to do with the fact that I'm using Apple's bluetooth keyboard (and mouse), but once the computer has actually restarted, why would it matter? Does the computer remember the BIOS from Windows when it restarts, and therefore fails to recognize my bluetooth? For the record I have to turn my keyboard off then on again when entering windows to get it to be recognized and work, but not the mouse, which works fine.

I have an iMac5,1 operating OSX 10.4.11. Recently, the reader has started to reject all DVDs after a few seconds. Reading about similar problems, I bought a laser lens cleaner. The problem still remains - the cleaner disc is rejected after a few seconds.
The instructions with the disc are designed for tray input rather than slot input. How can I play the disc from OSX commands? I have tried DVD player but pressing the play button it informs me it does not recognise the disc.
Where can I go from here?

My roomate as a powerbook g4 1.5ghz, it had been running 10.4.8. The computer will go into sleep mode randomly about every 10-15 seconds. Doesn't matter what program he's using. If he leaves the comp off for a few hours, it wont do it for a while and he can use it. Only thing we've found online is that people had that problem when they had faulty trackpads/trackpad sensors. But we don't think that is the issue we weren't getting an error message as they were in the console when it would occur. We called a local mac shop and they said it'd be 100 bucks to diagnose the problem, and probably it sounded like he would need a new logic board for another 700 + Labour.
A friend at school had the Apple Service Diagnostics 2.5.8 boot disk. He told us to give it a shot rather than paying the 100 bucks to get it "checked out" as it would most likely tell us what, if anything was wrong. We ran it, all hardware and software tests passed w/o any errors. We even tried doing a full format and reinstall of OS X 10.4.1, it got through the install procedure, and it seemed to be working ok for about 30 minutes, then suddenly the problem started again! So I that makes me think its not software related. So far two software "tests" and one full ASD hardware test got us nowhere. He's tried a lot of stuff he found online, but nothing has worked. Such as resetting all the various rams and sensors and PMU.

All right, so the problem started when I installed Growl for Mail.app.
I installed it, launched Mail, got a beach ball hurling towards me, then it quit.
That is the main reason I think it has something to do with Growl.
So I guess my question is, what should I do? Right now the only thing I know to do is "uninstall" it. By the way, does anyone know the files to delete if I want to "uninstall" it?

New 13" MBP, and the time to sleep is about 15-30 seconds. My 12" powerbook would do it in a third of the time. Any thoughts? How long does it take others?

I've got my mom's Gateway Quad-Core desktop PC (running Windows 7) hooked up at my house for the time being. I have an Airport Extreme as my router, and also an Airport Express used as a network extender. I hooked up the Airport Express this morning, and that's all configured correctly and working properly (so it's not an out-of-range issue). The Gateway Desktop has a full 5-bar connection, and is running a USB D-Link DWA-140 wireless network adapter. The problem is that it cuts the connection literally about every 30 seconds.
Here's what I've done so far:
1) Installed the updated D-link drivers. Didn't work.
2) Installed the NEWER, updated Ralink drivers (parent company for D-link...the DWA-140 adapter has the RT-2870 inside, so I used the appropriate driver, which I thought surely would fix it...that's what everyone told me to do thus far). Didn't work.
3) Checked my USB Power Settings in control panel and set them to never put the ports to sleep. Rebooted. Didn't work.
4) Right-clicked the adapter under "devices" and checked the power management settings. Set them to "maximum performance" (that's all I could do).

I wonder if it is something to do with gmail. as gmail has been asking to store emails on my local drive and I have been saying no as I was worried it might be a virus or something - maybe I have too many emails on the system. I just dont know. I am using Firefox in the meantime but feel frustrated as I dont know my way around as well and I have work to get on with!

Two days ago, I pluged in a Maxor hard drive that loaded some softwear onto my computer. I reformatted the drive because it did not work. Shortly after this I started reciving this message:
"You can't open the application NotificationExec because Power PC applications are no longer supported."
I cannot type for more than seconds before any program kicks my out to the message again. It has taken 15 minutes just to type this post.
