Desktops :: G5 Freezes While Startup In Winter

Jan 23, 2009

system info:
Dual 1.8GHz PowerPC G5
OS 10.5.6

My computer is 4.5 years old. And every winter for the past 3 years it's had troubles starting up in the cold mornings. Gradually getting worse each winter.

Today wasn't too bad.. it started up on the 2nd try. But on a particularly frosty day it might take 3 goes.

It freezes anywhere between the grey screen to the loading wheel to the desktops appearance.

Sometimes it freezes and gives the message to switch it off by the power button.

On occasion it freezes and shows me this: [URL]

PowerPC :: G5 Freezes During Startup Fan Speeds Up?

Aug 21, 2008

My computer crashed today and hasn't been able to boot back up since. It gets to the grey screen with the Apple logo and stops. The fan then ramps itself up to overdrive.

I've started it up in target disk mode and repaired it using Diskwarrior on my macbook. It had to repair quite a bit and then it showed up on the desktop of the laptop. I can read, write and pull from it. I then ejected the powermac and started it up again to find the same problem persisting.

Intel Mac :: Freezes On Any Program After Startup?

Jul 4, 2012

My 5 y.o. aluminum iMac recently went kaput on me. Problems it has: 

-Freezes on any program after startup

-Freezes during safe boot mode; grey line won't progress past first 10% or so

-DVD stuck in optical drive and nothing works to get it out, so I can't boot from my install disk

-fsck -fy doesn't complete, and keeps timing out

-Migration Assistant either stalls the receiving computer, or just gives me "network" errors (even though I'm connected to the internet), or other errors. 

I can't run terminal, disk utility, or any other kind of programs.How do I rescue my files from my failing iMac??

Mac Pro :: Randomly Freezes At Startup And Shutdown

Jun 23, 2014

I have got a problem with my brand new Mac Pro. It randomly freezes at start-up and shutdown. I sometimes am able to work around the problem by turning on the monitors last or switching them off first but it does not always work and is a pain anyway. While waiting for Apple or another manufacturer to release a decently priced 4k display, I am using 2 HP 24' monitors inherited from my previous desktop. 

One is connected via an HDMI cable (HP2405) and the other via a thunderbolt to HDMI cable with a DVI adapter (HP2448).Would I be better of using a Thunderbolt connection for both displays ? Or any other connection?

IMac :: Mouse Freezes After Few Minutes Of Startup

Sep 25, 2010

This is my first Mac user problem posting going back to my original SE! Power PC based imac running leopard 10.5.8 starts up but then mouse freezes after a few mins. Managed to change sleep mode to 15mins - same problem. Can't boot from Disk as same problem, also command+option and shift all still have mouse unmoved! Obvious change of keyboard and mouse have no effect. Could this be related to offspring's addition of ipad plugged into usb a few weeks back? He tends to unplug the device without ejecting!

IMac :: Replaced HD But System Freezes On Startup

Nov 10, 2009

I have a early 09 iMac 2.93Ghz with 6GB of ram. About a month ago it kept freezing at the grey startup screen. I took it to Apple and two trips to Apple later my hard drive was replaced. One month later here I am and the problem is happening again, the same exact problem. I turn on the iMac it goes to the grey screen, the beach ball "like" thing starts spinning and then it freezes in the middle of it and I have to do a hard power off(hold down the power button). Any ideas!? I already scheduled a appointment with Apple tomorrow afternoon but its a royal pain in the a** to keep shuffling my iMac between home and the Apple store. This will be my 4th trip in for the same problem, btw.

Does anyone in here know anything about the error message?

Software :: One User Account Freezes On Startup?

Mar 15, 2009

I'm on a G5 in OS X 10.3.9 running a few user accounts. The main one (aside from the system admin account) has quite a bit of software on it and it freezes on startup while the others work fine. I don't think its a RAM issue because I also run an external drive from time to time and it works perfectly. Something I've installed is freezing the system under the one user account but I'm not sure what.

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....................

IMac (Intel) :: Freezes At White Screen During Startup?

Jun 2, 2014

I was off of my iMac for an hour or two so my screen saver when on.  I went to wake the computer and it was frozen.  I tried using the keyboard and mouse to wake up the computer from the screen saver, but it would not work, so I powered the iMac down manually from the button on the back.  I let it sit for 15 minutes, then I tried to start the computer up again.  Now at start up, I get to a blank white screen with the spinning moving pin wheel, and that is it.

MacBook Pro :: Snow Leopard Startup Freezes At Grey Screen?

Mar 15, 2012

My Snow leopard machine hangs during startup at the screen with the Grey Apple logo.  It appears there is a SW issue with my OS X boot partition.  Here are facts I have learned:The computer boots fine if I hold option at startup and select my boot camp partitionThe compute boots fine if I attach an external HD with OS X 10.6Running a disk repair from the external HD, I see the following two issues that are repaired.  Also, note the last line about boot partitionsAfter this disk repair, the disk will still not boot, it hangs at the Grey Apple logo.Booting in safe mode does not resolve the issue, the machine will still not boot to a desktopBooting in Verbose mode, drivers initialize with the last succesful line being the ethernet drives (I believe) and then the hangup occurs.  It is unclear what state the boot process is at on the hangup. 

This situation has happen twice in the past few weeks.  The first time I did a reinstall of OS X to resolve the issue.  Then, the issue appeared again approximately two weeks later.  I'm hoping to avoid a second reinstall (And really, avoid this issue in the future).  It seems perhaps something in the boot partition table or the OS partition, although disk utility says the partition is fine.  I have downloaded Test Disk 6.13 to look at the partition table, but I don't know how to interpret the outputs of that program.

MacBook Pro :: Lion Loop-freezes At Session Startup Login On 15”

Apr 10, 2012

Notebooks affected by this troubleshoot:Macbook Pro 15" 6,2 Mid 2010 (OS 10.7.3) with all Apple updates installed - 2,66Ghz Core i7 - Apple SSD 128GBMacbook Pro 15" Late 2011 (OS 10.7.2) - 2,4Ghz Core i7 - standard specs Troubleshoot : At startup, Lion freezes before the user is able to type his login/password. We see the login prompt interface of Lion, but can't even move mouse cursor.Keyboard's inactive too because system is frozen.So you must force a shutdown.And it's a loop-freezes. You'll try several times to boot your laptop before it will succeed to open. (it's a 5-times boot to succeed - average) I've tried several times: P-Ram reset, repair the permissions of Macintosh HD with latest Lion recovery & from an external boot too.None of this has solved this issue. I'm sure I'm not the only one who saw that issue. Have to boot 5 or 10 times his Macbook Pro to succeed a boot is not a normal use

Laptops :: MacBook Freezes On Startup / Can't Find Test For Hard Drive

Apr 11, 2010

My August 2007 MacBook runs OSX 10.4.10. It has performed flawlessly since my daughter bought it in 2007, and perfectly after I purchased it from her last september. The other night I was surfing the web while flying on a commercial airliner. (GoGoNet or something similar) Performance was kind of slow but I attributed that to the in-air wifi, which I had never used before. Then the browser started to hang with the spinning pinwheel. Option apple escape WOULD NOT force quit safari. After a few shutdowns using only the power button, the mac hung up on startup. I hear the chime, see the apple icon, the gear turns but it never goes past that point. It may be significant that the plane was flying through scary turbulence when my problems began.

When I boot up using the mac install disk 1, I can get it to start cleanly using the C key, the D key and NO keys. But when I run the hardware diagnostic, both short and long test, the mac comes up 100% clean. But i cannot see any test for the hard drive. When I try to run disk utility, the colored pinwheel arrives and it never goes away. When I go down the road of re-installing the system software, I cannot see the target drive.

When I put my ear on the deck, just to the right of the track-pad, I can hear the hard drive quietly spinning away with regular - not random - clicks.

I see that Apple is quietly replacing these hard-drives, but the affected computers seem to have a folder/question mark on the desktop on startup, not the apple/spinning gear.

I really would like to be able to recover my photos and some files if the hard drive is going to be swapped. But I am resigned to the situation that these un-backed-up files will be forever lost.

PowerBook :: G4 Freezes At Startup Phase - Stuck At Initial Gray Screen

My Powebook G4 12" (model A1010) during its start-up phase remains stuck on the "initial gray screen" without displaying the apple logo. However, I can access the system through the console provided by Open Firmware. 

I would like to ask you what could be the problem and where such problem may reside (hard drives, memory, main board, etc).

OS X :: Computer Freezes - Must Reset?

Jul 15, 2009

After having this Mac for a month, I've been surprised for the past few days to find that after an hour to three hours of use, the computer might freeze and then state that it must reset. Is this the result of any certain common activity in Mac OS that I could avoid just by changing my usage habits?

OS X :: Switches Spaces Freezes Computer?

Jan 5, 2011

I recently upgraded to 10.6.5 from 10.5.8. Ever since then I have had a problem with spaces. The problem is as follows:

When switching Spaces, there is the onscreen graphic along the bottom, telling you which space you just switched to. However, sometimes when switching spaces on SL 10.6.5, the graphic will stay there and wont disappear as it should. When it just stays there, the entire keyboard stops working because Mac OS X still thinks I am performing the Spaces switch. A logout is required.

I am running 10.6.5 with all updates applied.

I searched for this problem both on MR & on google, and although it seems that I am not the only one with the problem, I can find neither a cause, nor a solution.
