My iMac G5 1.6 Ghz Won't Boot. Shuts Down at Gray Screen. HELP!
Hi guys. I need some help. I have an iMac G5 that seems to be having some serious problems. It is a 17" 1.6 Ghz w/ 1GB of RAM.
The problem:
• When I press the power button, I get the beautiful Mac chime, and the LCD turns on to the gray apple screen. I get the spinning gray bars below the apple, and then...it shuts down. Sometimes it doesn't even make it to the gray screen and it shuts down.
What I have done recently/tried.
• I installed iLife '06 and all the updates a day or two before this began.
• I reset the PRAM.
• I tried booting in safe-mode...no luck.
• I tried starting from the factory CD. The drive begins to spin, and then it shuts down.
When this first happened (yesterday), I started it in safe-mode, and everything looked ok. I zapped the PRAM, and then started it up, and once again, everything looked ok. That was last night. When I got home from work tonight, none of those things worked, and I am now looking for some help from you guys. Any suggestions? Thanks, in advance, for the help.
BTW, I think I'm running 10.4, but I'm not certain because I can't start it up to tell.
See if your machine falls under the parameters of power supply or video and power issues.
Please post back and let us know,
Miriam

Mac Mini won't boot, distorted startup chime, gray screen
Hi all --
I've seen similar posts (http://discussions.apple.com/thread.jspa?messageID=12170891�) but thought I'd start a new one, mainly because I haven't heard anyone mention the startup chime.
I woke up my 2007 stock Mac Mini Friday morning and the cursor was frozen. Unplugged and replugged the mouse to no avail. Couldn't force quit, so I had to power down. Restarted with a badly distored startup chime (not "speaker breakup" from excessive volume, just distortion, and some "stuttering") and a gray screen that didn't go away. Restarted many, many times. Inserted Snow Leopard DVD to run Disc Utility but it wasn't recognized -- just a gray screen. Tried resetting the PMU and SMC with no results. Tried booting into single-user mode (with a wired USB keyboard) to eject the DVD, but no luck. Tried open firmware, but nothing. Once in an while I would get the Apple icon and a spinning progress bar that never went away.
Took it to the Genius Bar, where they tried to boot from a Firewire drive, with no success. The best they could do was tell me my 17-month old Mac was out of warranty. That confirmed, I took it home, cracked it open and removed the Snow Leopard DVD (with a credit card) to insert the install disc it shipped with. That didn't work. A couple of times it looked like it would, but then after the spinning bar I got the multilingual system bomb message. Tried to run Hardware Test, but nothing. Put in original Disc 2... and that gave me a flashing folder! Progress! Forced the DVD out and slipped in Disc 1. That started to read, and then I got some kernel-panic looking text and a shutdown. My last attempt was to create a USB boot drive from the original install discs, but my old Sawtooth won't let me run the installer.
Is there any hope at this point? I just bought the thing last May, so I've had it less than a year and a half. The distorted startup chime makes me think the logic board is fried and no amount of fooling with the startup drive will make a difference. The only thing out of the ordinary in this case was that it went to sleep last Thursday night with a DV camera hooked up via Firewire.
I'm not thrilled about giving Apple any more money for another Mini, but I'm heavily invested in Logic Studio so I don't have much of a choice of platform.
I'm pretty sure I'm doomed, but I thought I'd post anyway. A quick internet search shows I'm not the only one with the gray screen of death on a fairly new Mini. Thanks in advance for any pointers.Thanks.
The Genius was able to get to the Apple logo and spinning... thing (what used to be the beachball). His theory was that as long as the Snow Leopard disc was in there, the boot process would never get to the Firewire port. Once I got home I literally pried the Snow Leopard disc out and put in the original install disc. But any progress whatsoever ends in the system bomb message.
Thing is, I had tried to eject the disc by booting with the mouse button down. But on restarting, the laser in the optical mouse flashes quickly, once. I don't think the USB ports are going "live" at all... so I can't get into single user mode, safe mode, hardware test, anything. The Genius' keyboard was no help in that regard. So yeah, I suspect a hardware problem.
A search of "gray screen of death" shows this happening to a lot of models. -
IMac shuts down after gray screen
I accidently unplugged my iMac while it was on. Now it turns on shows the gray screen with Apple logo then an empty progress bar flashes below the logo a couple of times and then it shuts off.
I've tried resetting my PRAM, unplugging everything from the USB port and disk repair. Nothing seems to work. I would like to be able to recover my files because unfortunately I didn't get around to backing them up.
Any suggestions?
Thanks!You will need to start your computer with the original system disk that came with your computer and run Disk Utility, then click repair disk. I see in your statement your said your ran Disk Repair if it is the same did is show any errors on your hard drive. If it didn't find any errors then you may need to use something like DiskWarrior or Tech Tool Pro. Also try to start your system in safe mode, hold down the shift key will restarting your Mac.

IMac shuts down after gray screen/spinning wheel
Every time I start my iMac G5, I hear the chime and then see the gray screen Apple with the spinning wheel, but then it shuts down, never making it to the blue screen and desktop.
Can anyone tell me what the cause of this might be?
Thanks!Are you able to boot into safe mode? Are you able to boot from your OSX installation disk?

Oh, so this is where I ask my question. Sorry, first time here. As I was saying in my long intro, the gray screen come up and the thing is spinning at the bottom, but nothing happens. Then the fan starts reving up like it is about to explode and I have to manually shut it off. A friend told me to start it up with the OS disk and then go to utilities. I couldn't find the thing, so I went out and bought another. Needless to say, it didn't work. Is there a key stroke to help jump start the machine? How can I get into this thing? I would prefer not to take it in because there are a lot of things on there I don't want just anyone to have access to.Thanks, in advance, for your help!
The last time you had to hold down cmd opt pr more than twice was a decade ago....
G5? PowerPC? 10.5? or earlier....

Your drive does need to be repaired, and best things to buy are another backup recovery drive, with a small OS X partition; a copy of Disk Warrior is expensive @ $90 but excellent and best.
Never bother with or use the drive or reinstall while there are errors. Don't take a "clean' bill from Apple Disk Utility to mean there are no errors. Only that it didn't find what it looked for.

Make sure to have multiple backup sets and of your system so if there is a serious problem, you can just erase and restore to be back runninig.
Sounds like your G5 though needs PMU reset, not PRAM, and the best way for those is to clear nvram instead. might even want to check for dust; tell what System Profile says (later) as to "PowerMacX,Y" or "MacProX,1"

The Utility menu is on the menu bar of an "OS X Install DVD" and at the point where you get to but stop at "install....' for OS X. you probably do need to install OS X on another drive to work from.
Oh, a real severe issue and damage to the drive directory or filesystem CAN in cases prevent booting from DVD (the system still tries to find and see what boot volumes are present) and can help to pull or disconnect the drive. Putting a drive in a FW case to turn on after startup is very useful. -
Macbook Pro 10.8 won't shut down. Gray screen with spinning wheel.
Previous it happened on 10.6.8 snow leppord. I thought it might be the RAM problem, so i went ahead and purchased a 16GB RAM. Now I got the RAM up running, i upgraded the computer to 10.8 mountain lion. I thought the problem should be gone by now. But somehow, it happened all over again, everytime when i use microsoft office 2011. I even quit every single app fron the Active Monitor (include Active Monitor), and wait for about 5min before shutdown, the gray screen with spinning wheel appeared again. I repair the disk from recovery HD, according to that, there is no problem anymore. But, once again it happened after i used Microsoft office 2011. Is there anyways i could fix it? I suppose uninstall it will make it work, but it's vital.

My very reliable Mac mini (bought in 2006) failed last night. Circumstances: I was installing a new software package (scan snap manager) via CD and the computer hung during the install. The pointer was a spinning beachball but it would move around screen. The keyboard had no effect. I had to shutdown the computer via the power button. After that the computer would shutdown shortly after a restart. I tried pressing the shift button, the control button, the option button and the command button during the restart. Finally, after web searches I did a SMC reset. Nothing happened and the CD remained in the computer.
Full disclosure, the superdrive had failed about a year ago with a disc inside and I took it to the Genius bar. They decided that the superdrive was flaky but managed to recover my disc after turning the computer on its side. They said that the drive needed to be replaced but that the computer wasn't worth the work. After several months I tried the drive again and it worked and has continued to do so. It's been used lightly. When I installed the software disc last night the drive immediately sounded very noisy so I suspect that the drive failed. I was unable to get the disc to eject using any technique I could find on the web so I opened the computer and physically removed the drive by unscrewing the superdrive cover. After doing that I replaced the screws and reassembled the computer. I was unable to start it and I eventually removed the superdrive. It's now not in the computer.
Since opening the computer, removing the disc and reassembling the computer I've had similar symptoms with or without the superdrive installed. They are as follows:
Start the computer
The LED comes on
The boot chime sounds
The screen stays dark
The LED goes off about 7 seconds after the boot chime and the computer is apparently shut down.
I can change the behavior by holding down the shift or control keys (perhaps other keys as well). In this case shortly after the boot chime sounds the grey screen comes on and the circle begins to spin. Then the LED goes off and the computer shuts down. The total time between the chime and the LED going off is still about 7 seconds.
Any thoughts?OK. The PRAM battery's replaced and the computer reassembled but the behavior is the same. Any further thoughts?

Lion won't boot. Stuck on gray screen
Was trying to work with HP support to troubleshoot a problem communicating with the scanner portion of an HP OfficeJet 6500a E710 bought at an Apple Store. They had me run the HP uninstaller to remove all HP software in scrub mode. They then asked to run verify disk permissions. Then reboot.
Upon reboot I get the gray screen with the spinner, and it sits there forever.
Any ideas what could be wrong or how to get around it?
I've used Command-V to get verbose output during boot. Last thing it says is that its running fsck_hfs. But I see no other messages after that. The CPU fan is spun up as if the CPU is busy.
I've booted using the recovery image and checked the disk. Everything checks out ok.
I've booted into single user mode and run fsck and fsck_hfs. Both ran fine.
I tried to startup in safe mode verbose. I let it sit for hours and after 3 hours it booted. But then I rebooted and it got stuck again.
Any suggestions appreciated. This is a machine I use for work and income. Neither of which are happening right now.
I've been trying to research how Lion starts up to see where it invokes fsck_hfs, but I haven't found any reference online to describe how Lion starts up. All references I've found refer to Tiger or earlier which has a very different boot sequence.
ThanksCall Apple. Seriously.

My dad has a brand new iMac. If he quits an app, this window closes, but the app won't finish shutting down, Force quitting does not work. Once another app is opened, it will not close either. Now none of the apps on the dock are responding. I asked him to click on the apple, and drop down to "About this Mac", but that wouldn't open either. Any ideas? If I was at his house, I would call Apple Care in a heartbeat, but am home with my sick daughter,,, Thanks!
For starters, have him open Disk Utility in Applications>Utilities, select the volume (the indented listing) and Verify Disk. If it reports any problems, have him try a Safe Boot by holding the Shift key at startup. This boot will take much longer than usual. It's checking and trying to repair the drive directory, if possible. Once in Safe Boot, have him repair Permissions.
For other Disk repair remedies see
http://support.apple.com/kb/TS1417
Also, have him try a PRAM Reset. At the startup chime, hold down CMD-Option-P-R together, listen for two more chimes, total three, then let go to finish booting.
Also, is he running any AV? If so, have him uninstall it. It might be responsible for this behavior. (There are no viruses for OS X.) -
I have an older IMac 5. I installed snow Leopard on. Now my DVD drive is not working. Discs go in but it dosn't boot up or show in finder. Then disc won't eject unless i shut down and restart. HELP !
Snow Leopard cannot run on a PPC G5 Mac as it requires an Intel processor. Please confirm what Mac you have.

Mountain Lion won't sleep, shut down, restart, or log out.
Hi All,
After Mountain Lion my 2010 iMac 27" won't sleep, shut down, restart, or log out.
Basically most functionalities of clicking the apple icon are disabled - "About this Mac" doesn't work either.
Please help!
Before Apple fixes this, is there another way of putting my Mac to sleep or shut down?Just adding another voice to the chorus. Since upgrading to Mountain Lion my computer will not sleep. The cursor freezes when I try to invoke sleep but the computer and monitor remain on. The cursor unfreezes when I tap the spacebar the way I would normally do to wake from sleep. Fortunately, shutdown, restart and logout function normally, so I guess I should count my blessings. This isn't my only problem with Mountain Lion, but I didn't want to muddy the waters on this thread with other issues.
Dual quad-core MacPro3,1 -
my imac (intel core i5, OS 10.10.1) shuts down every night and will not "wake up" next morning -- it never used to do that -- if I hold down the start button more than twice for many seconds, then it will finally boot up and works fine all day – I’ve tried shutting it down and unplugging it, and that does not work -- I’ve run disk utilities checked permissions, and run anti-virus and get no adverse results – I cannot figure out what is different that causes this problem
From previous experience 3 indicates a shutdown initiated by the SMC (System Management Controller) — hardware responsible for many low-level functions including power, sleep, lights, and fan activity.
Try resetting it:
Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
