I have a Dual 1.8Ghz G5 that hangs on startup, right at the grey screen, the pinwheel will freeze.
I have tried:
- Resetting pram and nvram
- 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.
I have a dual Thunderbolt setup (chained). When I disconnect my Macbook Pro (Early 2013, Retina 15", 2.8 GHz, i7, 10.9.4 (13E28)) and open the lid, the display back light comes on but the screen remains black. I can hit caps lock and the light toggles. But, I never get beyond the black screen to a login. I need to do a hard reset (holding down power button) to recover every single time I disconnect from my displays. Â

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?

Unexpected 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.
View 1 Replies View RelatedI'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.
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. Here are the answers to the "Read This Before Posting" questions: What OS X system (version) are you running? 10.4.1.1
--Have you run permissions yet? Not sure exactly what that means, but attempted to repair them using Disk Utility and then DiskWarrior
--Have you used Disk Utility from the CD to Repair Disk? Yes
--What devices are connected to your machine? USB Keyboard, USB mouse connected through keyboard port, lcd monitor,
ethernet cable

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 ...Â

View 5 Replies View RelatedMy 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.

View 8 Replies View RelatedI 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....................
My computer hangs on startup. It's a PowerBook 12� G4 with 10.3.9.
First, the screen flashes black, then blue, then I get the normal startup progress bar. At the end, though, it hangs. If the ethernet cord is in, it hangs at "Waiting for network services" or something like that. If the ethernet cord is out, it hangs at "Login window starting".
The bigger problem is that my system install CDs are in the U.S., and I'm in China for the next six weeks.
I'm helping troubleshoot an issue with a Mac Mini running Tiger 10.4. Basically, it was set up to automatically login, but the original owner never wrote down the user name OR password. So I went to work trying to figure these both out. I worked in single user mode to figure out the username pretty easily. But the password became a real issue. First off, the Password Reset option on the install CD would not work. When I clicked on my Hard Drive to change that password, it would gray out the options. So, I went to single user mode commands. I tried:
1. Booting into single user mode
2. Type fsck -fy
3. Type mount -uw /
4. Type launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist
5. Type dscl . -passwd /Users/username password, replacing username with the targeted user and password with the desired password.
6. Reboot
Didn't work. Neither did the more Tiger-specific commands, where you'd type:
sh /etc/rc...............
Macbook Air, Rev A. Worked like a charm for 1.5 years.Upgraded to a Rev c SSD and gave the Rev A to the wife.She installed NOTHING.Within a few weeks it started running VERY slow. I'm talking 2 minutes of beach ball per click.I use Disk Utility to check the drive. No problems of any kind.
Rebooting would take -- and I'm not exaggerating -- over an hour. First it would sit with a grey screen for 5 minutes. Then with an apple logo for 10 more. Then with the little spinning circle for 30. Then the desktop background would show up and sit for 20 minutes, etc.
Was gonna upgrade to Snow Leopard so what the heck, backed it all up and installed Snow Leopard. To my surprise, it instaled Snow Leopard on top of the old OS -- it kept all the files around so no need to restore from backup.
Speed problem SOLVED!Then a few weeks later the same problems.This time I check the drive AND run the hardware test. No problems.I ERASED the entire drive. I installed Snow Leopard.All is good for a few weeks.Then the problem came back a 3rd time.
I go to reinstall a 3rd time and Snow Leopard doesn't even acknowledge that there's a hard drive in the machine! And when I look in system profiler it says there's no drive of any sort. Yet it will reboot and run... just VERRRRRYYYY slowly.
I'm ready to replace the drive with a Runcore SSD or some such other device but I want to be sure the problem is the drive and not some other aspect of the hardware (motherboard, RAM, etc.)Anyone ever seen this? Anyone have any ideas as to how to investigate, solve, conquer, save myself from madness??
I have a new MacBook Air running Lion. Every time I use my backup software, it changes the permissions on my external drives, and I have to change them from read only to read & write, so I've gotten in that habit. At one point, I noticed that the permissions on my internal *startup disc* were read only, so I (foolishly, I now know) changed the permissions on the startup disc to read & write, with apply to all enclosed items checked. As I continued working, I got messages that a number of extensions could not be used and will be disabled (or something like that). I decided to reboot, so the computer could reset and hopefully correct things.
When I tried to boot, it hung up on the grey screen with the Apple logo and the spinning clock/gear. I let it spin for a while, then forced power down and tried to boot in safe mode. The progress bar appeared as it's supposed to, but when the progress bar finished, it went back to the grey screen and hung up again. I let it spin for over 40 minutes before powering down, just in case it was doing diagnostics or something. I don't have access to the original OS DVD (nor do I have an optical drive to put it in). Any way for getting the computer to boot, at least in safe mode?
Is there a way to get a USB startup on the dual 1.8ghz G5?My macbook enables USB boot obviously but my ppc does not support it
View 5 Replies View RelatedI believe the Macs at my college allow the user to select from either Mac OSX or Windows at startup. However, it's a little different than holding down the option key at startup. I think it shows both at startup by default and if none is chosen, Mac will boot automatically within a couple of seconds.
View 4 Replies View RelatedI 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 searched but couldn't find anything that I needed. I picked up some MDDs(dual 1.25 & FW800 1ghz) with bad power supplies and eying up another MDD(Dual 867) which is working. Will the dual 1.25 and single 1ghz processor daughter card work on the previous model? I know the System clock is different and heard about removing a resister on the first gens to 167mhz FSB. I will also try and transplant the PSU too to check to see if my 2 MDDs fully work or not.

What I need to know is if I can use two PCI video cards both with Dual Monitor outputs, and if so, which cards should I buy, and where? I found some video cards on ebay that are PCI, and it is quartz extreme compatible, but I am unable to use it with the AGP card already installed.

View 24 Replies View RelatedI'm just going to order a new Mac Pro and noticed that it was slightly cheaper to order the base dual processor model and buy the 2.93GHz hex cores myself. A couple of questions arise:
Will my AppleCare still be valid or will I have to keep the 2.4GHz Xeons if I need to return it to Apple for any reason?
Is there market for the 2.4GHz processors?
Can I upgrade to the 3.33GHz processors or will this not work?
I scanned the posts and didn't see this question, but honestly I didn't read all 20K + messages.I bought in late 2005 a dual 2.3 G5, about 6 months before the Mac/Windows combination came out. Does anyone know if I can upgrade or is it too costly to do so compared to buying a new machine.

I am using Stata, a statistical analysis program. Recently, when I try to open a file, using File Open, the program hangs and I have to force it to quit. I can open files easily if I use Recent files. When the file gets open, I can do everything I should be able to do with the program. Analysis, graphics, etc. It is JUST when I do File Open that it hangs, and it seems to be ONLY with Stata.Â
