My iMac will chime, then hang on the grey apple screen with the spinning gear. After a few minutes, it shuts off. Tried resetting Pram and all... Did not work. I troubleshooted using another website, and found it to be an I/O Error. The issue is I need to reinstall the OS, however, when I boot the install CD it hangs the minute I click the mouse or keyboard.
View 8 RepliesI've got a 1st generation iMac G5 (I think, from 2004) running 10.4.x that has become 'the family' computer since I upgraded this past winter. I haven't been keeping up with updates and decided about 3 weeks ago to finally go through and update everything; had been at least 4 mo.s since the last update and udates included Java Script, iTunes and a Security Update. I started downloading the updates then quit Safari (which had previously been running) walked away to do other things around the house (since it would take a while) and when I came back I had an error message that the logout (to restart - which was required for the Security Update) had timed out because Safari would/could not quit. I clicked OK, force quit Safari and shut down the computer (since no one was going to be using it for the rest of the day and a restart was required anyway).
Came back the next day to startup the computer and it just hung at the blue screen with the mouse arrow. Assuming there was something wrong with the update that was just installed OR the startup disk I reset the PRAM/NVRAM: no change. Tried starting in safe mode: wouldn't (and still won't) move past the blue screen with spinning gear. Tried to boot from install disc to repair the HDD with Disk Utility: Couldn't repair the disk volume (Invalid leaf record count: should be 13 was 1203). Tried single user fsck: scanned twice and reported volume repaired, went to restart - still hangs, tried to boot in safe mode again - still hangs at blue screen with spinning gear. And that's where I'm at now. Anyone got any good other ideas out there? I've searched a lot and haven't found anything I haven't tried. I'm guessing the installed update(s) never completely installed and screwed something up on the startup disk. But I can't access ANYTHING to figure out if that was the problem. I would really like to keep this computer for the kids but don't want to spend any money on it if I can avoid it.
I have a MacBook Pro from 2010 I believe with iOS Maverick installed. (MacKeeper is also on there, which I just found out is apparently malware)
So three days ago I was watching Netflix, the image froze, but the audio kept going. Figured my internet was slow, so I waited a little, nothing happened. pressed escape to leave the full screen mode, but nothing happened. None of the keys would do anything, not even the sound or brightness keys. So I did a force shut down by holding down the power button.
I waited a little, then decided to turn it back on. Start up sound played, white screen with grey apple logo and loading gear appeared together with a grey loading bar. I figured that this meant it had to repair something. But after about a minute or two it just went to a black screen/ shut down. I left it off for a day, tried it again, same thing. Next day I tried booting it up while holding the shift key to do the safe boot (I knew it wouldn't work since I already had the grey loading bar anyways), same thing happened.
Purchased this notebook used, but very nicely cared for, excellent condition. I ran the Apple Hardware Test and everything passed including the logic board.
The battery has 500+cycles. The problem is laptop shuts down at 50% or less of battery. Clock is wrong at startup but is correct a few seconds later.
Runs forever and very nicely on ac power.
I recently upgraded to Yosemite. Had problems with connecting to the Exchange server so I did a restore from my time machine from the day before I did the upgrade. Now the machine starts to turn on, then shuts down. The iMac does not have a CD drive.

I had removed the "everyone - Read Only" rights on the HD (on the iMac) and opened sharing so my MB could attach to it. Grey Apple Logo and progress circle upon startup now.Can changing these rights cause the system to not boot? I can go into single user mode but I am not sure what to do then.

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?
I have a 700MHz iMac G3, which froze during DVD playback and it needed to be rebooted. Now it will not boot, the gray screen comes up with the loading circle, but it will just shut down after about a minute. I have reset the PRAM, PMU and it is running 10.4. No beeps or anything when it shuts down, it just turns off.
View 13 Replies View RelatedThis morning, my G4 refused to start up as usual. Instead, I got a grey screen. Here's what I've tried so far and the results: Action: Started from DVD Install disk for Leopard to try an archive and install. Result: No hard drive was recognized for an install, archive and install, or erase and install, i.e., no drives appeared at all in the "Select a Destination" window, just empty white space. Action: Attempted safe boot (Command + Shift + V) Result: Flashing Globe Action: "Repair Disk" from Disk Utilities after starting from DVD Install disk for Leopard.
Result: Received "First Aid Failed" message. Error message read: "Catalog file entry not found for extent. Volume check failed." I can't even get it to eject the install disk (the "eject" key does nothing and there's no manual eject button for this Power Mac). This is a work computer and not having it functional is pretty hobbling so.
My iMac G5 (rev A) shuts down immediately after i put it to sleep mode after just starting up the computer. The longer the computer has been on before I put it to sleep, the longer it takes for the computer to shut down while in sleep mode. I already did the hardware test and it said there were no problems.

First, my MacPro did not accept my password. Earlier, our building had three power drops in a row, seconds apart. I don't know if this affected my computer accepting my password.Since then, my computer starts to boot up then suddenly shuts down. Is there some way I can boot up and get to admin controls?

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?

View 3 Replies View RelatedUnexpected 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.

- Starting from the install CD with the HD disconnected
neither of which worked.
Oddly enough, it will start and run the apple hardware check CD, and an advanced check reports everything as OK.
My old faithful G4 867 Quicksilver won't start up. The grey screen with the apple appears, then the progress bar over a blue background. The progress bar gets to full and the system hangs there.

More background on the situation:
I have zapped the PRAM.
It will not boot into safe mode..................
about half a year ago the address book in my Macbook started to grow uncontrolled until it had more than 100000 records, wherof 99% were empty or fragmented, This caused the app to be very slow and freeze from time to time.
I tried to delete the corrupted records, but because of the large database and an old Macbook, it took ages to delete just a couple of hundred records a time. Now the app refuses to start (it hangs before it even shows up), even as the first app after a reboot.
The iCloud address book is OK on the web and on my iPad, so if I just could empty and reset the app in Macbook, I could be back on track.
I've tried to move the addressbook file (AddressBook-v22.abcddb, 125,3 MB) to another library, and I've deleted the .plist files, but it doesn't help.
I can see that the process findnames grows to almost 1 GB in memory if I don't stop it, and so does the process AddressBookMobileMeSharingAgent ...
