Mac won't start...grey screen with timeout on 0xfd

My iMac is pretty new, a couple of months old...
I just started it up when I got home and I get a grey screen with something saying "Found a transaction past the completion deadline on bus 0xfrd, timing out! (Addr: 3 EP: 2)". I have no idea what any of this means, at the top theres some sort of 0xfrd code. Also "Process 1 of exec of sbin/launched failed errno 8.." I don't get it as i'm no computer expert...can someone please help? I have no idea whats going on...if it helps I have got an audio interface plugged in via usb, and a usb synth, but thats it, and it's been fine...until now - but I have noticed it slowing down slightly over the last few days....
I need my mac for tomorrow...
Thanks again,
Harry

I tried this but it didn't work. I think it is my keyboard because even when I turn the computer on the green led on the caps lock button doesn't light up. I even tried a regular USB keyboard and I had the same result.
I guess I will have to find my leopard CD.
Is it possible to just restore system settings from the leopard cd so that I don't lose all my data?

PB Won't start--grey screen with logo--no spinning wheel

Did an update that required a restart--got grey screen with the apple logo and that's all. Tried resetting the Pram and the PMU, no luck. Won't start in safe mode or from another DVD (tried both the original and my Tiger disks). It was working normally before the update (iTunes and I think an Airport update and a couple of other things). I've removed and re-installed the RAM with no change.

Thanks!
HD disconnected it starts from a CD. HD re-connected it now displays the spinning geary thing but doesn't get any further. Disk First Aid found and fixed many problems but it still won't go past the spinning thingy. It passed Apple's hardware tests. So--a new HD is likely in order but I want to try a more comprehensive disk repair program and recommendations for that and for a new HD are welcome!

Computer won't start, grey screen with Apple logo only. Ideas?

Last night my wife's G5 froze. It is a G5 2.0 running OS X 10.4.11. I shut it down (had to use the power button) and tried to restart. No luck, just made it to the grey screen with Apple logo and spinning wheel. After a few seconds the Apple logo disappeared and a black box took its place, then the wheel stopped spinning. It was late, decided top wait until morning before trying again.
This morning I tried to start up again. This time got a warning(?) in upper left that a Firmtek item had already started. I'm sorry I didn't write this all down at the time, so I don't remember the entire message. Since there is a Firmtek card installed in one of the PCI slots I thought that might be the problem, and I pulled the card, as well as another Adaptec card that was also installed. Tried to start again, got to grey screen with Apple but this time no spinning wheel.
Opened media slot manually and inserted Diskwarrior. Tried to start with Diskwarrior but again only reached grey screen. Let run for ~5 minutes, until fans started to run and were begining to get noisy.
Next I reset the PRAM. No luck, still stuck on grey screen. Tried Diskwarrior again, this time got another message in upper left. Here is most of it -
System Failure : cpu=1; code=60000009 (Invalid pmap)
Lateset crash info for cpu1;
Exception state (sv=0x609bb280)
PC=0x000a4ad0; MSR=0x02003000 followed by more similar strings, then
backtrace terminated - unaligned frame address; 0xfc088891
So what's the diagnosis? I've had various issues with my G5s in the past, but have never had one refuse to boot with Diskwarrior before.
Thanks in advance for any help!

Whew, could be many things, from RAM, (or RAM slots/solder issue), to CPU #1 being bad, (CPU#1 is actually the second one.
Does it boot into any of these modes?
Target mode...
http://support.apple.com/kb/HT1661
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

Mac won't start grey screen appearing

My power mac g5 that is running leopard wont boot up.
Everytime I try to start it, shows a grey screen telling me to restart the computer (appearing in english, french, spanish, and chineese i think). I accidentaly deleted a folder on the root menu of the HDD entitled "usr". How can i fix this.

I tried this but it didn't work. I think it is my keyboard because even when I turn the computer on the green led on the caps lock button doesn't light up. I even tried a regular USB keyboard and I had the same result.
I guess I will have to find my leopard CD.
Is it possible to just restore system settings from the leopard cd so that I don't lose all my data?

Mac won't start blinking folder with ?

Hello have a question, my mac won t start, it appears a folder with a ? Inside....can anybody help me.....

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive (CD/DVD drive) and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

G3 won't startup (grey screen with happy mac)

My sister has a iMac G3 that all of a sudden stopped working. When it's turned on, we get the chime, a grey screen and a happy mac, that's all. It just sits there. I've tried restarting with the C down, using the PRAM trick, putting in a CD startup disk (though not the one it came with), disconnecting the USB drve/hub, but get nothing. We've had problems with the CD drive before, so I wouldn't be surprised if that was broken too. Any help would be appreciated. It's a blue iMac (maybe a 350mhz?. Thanks in advance
iMAC G3 (350mhz) Mac OS 9.0.x

You may need to replace the PRAM battery. A weak or dead battery has been known to cause startup problems.
If you can startup from a Mac OS installation CD, you can run Disk First Aid from the CD (for Mac OS 9) in the Utilities folder, and verify (and repair if necessary) the internal drive.
If you suspect the CDROM drive, you can also try disconnecting the CDROM drive internally to see of this will allow the iMac to start up. Sometimes, a bad drive will prevent another drive on the IDE bus to not be recognized.

Ever since I upgraded to 10.9.5 on my mac firefox is a grey screen with no menu bar or anything... I've downloaded and reinstalled multiple times now... nothing

firefox is just an empty icon from what i can tell... when i upgraded to 10.9.5 on my mac firefox no longer works. it turns into a grey screen and then just ends up disappearing to the finder window... the application remains on, and won't force quit. I must re-start in order for it to Not be running... I've used firefox and mac for over 8 years and never seen anything like this.... I'm sure it's on the mac side of things, but I'm hoping y'all can fix it... it truly sucks to loose my favorite browser and all my saved bookmarked tabs and all

Your bad charger probably damaged something inside as well. Your hard drive directory may be damaged too.
If you lack a backup, you should read this:

Otherwise, bring it in for service.

Mac book pro has grey screen with apple in the middle

my mac book pro has a grey screen, apple in the middle and a spinning wheel. i have tried the command r. nothing is working

Mac OS X- Gray screen appears during startup
Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by one or more of these:
a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
b. Boot drive's directory has been corrupted - Repair with Disk Utility.
c. Critical system files are damaged or deleted - Reinstall OS X.
d. The disk drive is physically non-functional - Replace the hard drive.

Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.

2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

After update Mac Pro boots to grey screen with Kernel Panic. Help please.

It would be great if someone can help me out. Yesterday I did a software update of iTunes and osx (it said to ease update to Lion) and now my Mac Pro tower (MacPro3,1) boots to a grey screen, kernel panic, telling me that I need to power down and restart my machine. I can boot into osx via the safe mode but unfortunately I don't have an install disk to repair the system disk. What are my options?
The machine appears to work in safe mode. I have tried resetting the PRAM. Any help is greatly appreciated. Thanks.
In safe mode, I get this error report.

There's no point in reinstalling the same driver. It hasn't changed. It's incompatible with the OS update. Contact the device manufacturer to see if there's a driver update. In the meantime, you should physically remove the device so the driver doesn't load. If you uninstall the driver and leave the device installed, that might also cause a panic.

Intel iMac - won't start - grey screen & progress bar

I have a 2006 Intel iMac - 20" model, Intel Core Duo, 2GHz, 2GB RAM, 250GB HDD, etc. It was one of the very earliest Intel iMacs. Kept updated, running OS 10.6, etc.
It has worked extremely well for over 5 years - apart from the Superdrive being temperamental sometimes - but has suddenly gone wrong.
Last week the machine completely froze for no apparent reason. I had to force a reboot. This failed - grey screen and the grey spinning wheel (if that's what it's called), indefinitely.
Forced reboot again and this time held down the shift key to go into safe boot mode. This time it was successful, and I was able to get to the logon screen & log myself in. I opened Disk Utility & attempted to do some diagnostics but the machine froze again.
Looking around various other forum postings...I rebooted the machine in single user mode and was able to get to the command line to type 'fsck -fy' to attempt to fix disk problems. This failed repeatedly, with an error message 'invalid node structure'.
I tried to boot my machine from the OS X disc but my Superdrive refused to play ball - it would not read the disc (or any other disc for that matter, including a copy of DiskWarrior that I have).
I have now got hold of an external DVD drive in the hope that this would show up as a boot device when I switch the machine on while holding the option key down. No such luck - the drive powers up ok (power via USB) but I'm not given the option to boot from it - in fact that screen doesn't appear at all.
All that happens now on powering up - regardless of what I do - is the grey apple symbol appears and a progress bar beneath it. The progress bar gets stuck about 5% of the way along, and then after about 10 minutes it disappears and is replaced with the grey spinning wheel thingy. And then it just gets stuck - nothing else happens.
HELP!
All my important data is backed up on an external drive via Time Machine, so that should be safe, but I'm desperate to get the machine running again.
One thing that occurred to me is that I've had a program called ReFit installed on the machine which allowed me to run the machine as dual boot etc. (and I do have a couple of other small partitions on the drive, not currently used) but the ReFit welcome screen stopped appearing a couple of weeks ago for some reason. I'm wondering if this has somehow messed things up...?
Grateful for any suggestions...
Thanks,
Alan.

For the drive, you should be OK with any SATA 2 at 3 MB/s transfer speed. You could also use a SATA 1, no jumpers needed. (Not SATA 3 - can't be jumpered down.) The early 2006 Intels were 1.5 MB/s -- at least the drives were, so I'm assuming the SATA controller on the logic board was also. Might just be SATA 2 hadn't yet been introduced and can run the faster SATA 3 without jumpers. My guess is not. You should be able to set jumpers on the drive for backwards compatibility. You'll have to contact the drive manufacturer or go to their website for that info.
http://www.everymac.com/systems/apple/imac/stats/imac-core-2-duo-2.16-20-inch-sp ecs.html
As for the superdrive, I'd contact the manufacturer to check on compatibility.
Glad I'm able to help. BTW, in case you haven't noticed, maybe you want to have a look here.

TS3423 my start drive not responding. getting grey screen with question mark in a folder. when i use disk utility drive wont mount

When I turn on my Mac I get a grey screen with a folder with a question mark . Have tried the disk utility to no avail as the disk has apparently dismounted and will not mount even though the mount option is available. I have recently upgraded from snow leopard go os x maverick

This could be a software/state problem or a hardware problem. In your case it sounds like the latter but you should try the steps below in case it might help.

Mac mini won't start up. Grey screen with apple just freezes.

Mac mini won't start up. just get a grey screen with the apple and it freezes. Please help.

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."

Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitirion & use Disk Utility from there to Repair the Disk, then Repair Permissions.

My Mac won´t load. When I turn it on, I type the password, then it starts to load, but nothing happens. It gets stuck on the grey screen with the apple logo. I can´t go to an Apple store since I´m working in Bolivia. Thanks

RhysWills1,
which model MacBook Pro do you have, and which version of OS X is installed on it?

Powerbook won;t go past grey screen with apple logo on start up

Hi
I am getting very stressed, my powerbook g4 won;t go past the grey screen with the apple logo when switched on. I need to sort it ideally without another computer to go through but if that is necessary then I will do it. I have tried the RAM reboot but nothing, there is not even the spinning loading symbol just a grey screen - which it will stay on until I turn it off. Someone please help!!!!!!!!!!!!! Not sure of my OS as I can't turn my comp on, but I am running leopard on it

Welcome!
First, see if you can boot in Safe Mode, holding the Shift key during startup until you see a message about safe mode. Getting a desktop can take longer because Safe Mode forced some disk checking.s

Then you should have the install disks. They can be used to boot the computer for repair. Insert the DVD and press and hold the "c" key during startup. That will launch the installer BUT you don't want to reinstall yet. Find the install's Utilities menu and launch Disk Utility. From there you can check the hard drive and make some repairs.

That would require that your compute work enough to start in FireWire Target Disk Mode. FWTDM lets your hard drive show up on another Mac as if it were an external drive. You can test by starting the computer and holding the "t" key until you get a blue screen with a big yellow FireWire symbol. Looks like this:

I believe FWTDM's code is in firmware and not on the hard drive , so may let yo uaccess the disk form another computer.
