Bash update stuck on gray screen

I received a notification to install the new bash update for Mavericks. I clicked the button and the install process began by rebooting my laptop to a light gray screen with nothing but the cursor.
The software update did warn that it would reboot to a grey screen for a bit before rebooting back into the OS. However its been stuck on this grey screen for over an hour. The screen is completely unresponsive - I can't move the cursor and nothing happens when I press some keys on the keyboard.
Any advice on what to do next? I'd like to just power the thing down and reboot it myself, and perhaps try the update again later, but worries this will effectively "brick" my laptop. What can I do?

One more detail. I unfortunately had my FitBit dongle connected to the laptop during the update.
I've removed the dongle; can I try rebooting with dongle unplugged? Will rebooting from this state possibly mess up my laptop?

Mac Mini Stuck at Gray Screen

Hi, I have an Intel based mac mini running 10.4.6 I believe what ever is the latest tiger version. Upon restarting after installed updates computer can not go past the apple logo with the spinning wheel underneath it. I have restarted and tried all of the different key combinations the only one it will recognize is the option key. I have used the option key to select the c drive where the operating system is installed but it goes right back to being stuck at gray screen. I have used the option key to also let me use the install disc to run disk utility and repair the disc which said volume is verified and repaired and good to go. Only thing I haven't tried is firewire boot but at this point I don't think thats the right answer. Im thinking its hardware issue any ideas or thoughts would be greatly appreciated. Thanks in advance for taking the time to help me out- Ryan

Will it start up in Safe mode?

If it can start up in Safe mode, that would point to a problem specific to your account, and probably a Login Item given that it hangs the way it does at the gray screen with spinny wheel. In that case, take a look at this procedure, too.

Boot stuck at gray screen

I have a 24" silver iMac. Boot gets stuck at gray screen with gray apple showing and wheel continuously spinning. Never gets to blue screen. I have tried booting from system CD and running disk repair and repair permissions. They are fine. I have tried zapping PRAM. I have tried booting with everything disconnected except keyboard. (all recommended elsewhere in these discussions.) So, for the THIRD time in the 5 months I have had this iMac, I am in the process of reinstalling the system from the CDs. THEN, as you know, I'll have to do all the updates. I AM GETTING TIRED OF THIS! (My G4 and MBP don't have these problems (I shouldn't have said that.)) Anyone else having these problems or have any other ways to deal with this? I wonder if it has anything to do with my trying to install, via software update, the latest update for QT. It wouldn't install, saying I didn't have permission or authority or something.

I hate to disagree, but I have had this happen at
least 4-5 times.
1. Happened (Before) I had an external HD attached, as Well as (After.)
(so HD not the issue.)
2. I had only the bare essentials installed on Tiger OS 4.10, B4 buying leopard.
(No other Software Installed, and NOTHING from 2nd install disk. No Optional Programs)
(Makes me rule out Quicktime.
3. I also Had same Grey Screen, Tried Disk Utility from cold boot (DVD)
Removed 1 Simm Chip And reset Pram. (Yes, I waited for 2nd chime.)
No Other OS or ANY Windows Products on this system.
Tried Cold Boot With DVD,
(made sure Active Boot Drive was DVD, NOT HD)
In Addition, Booted While Holding;
a. Shift Key - (Safe Boot)
b. Opt Key - ( I've forgotten )
c. C - Key (Password Change - No Help)
d. D - Key (verify/repair disk or permissions useless.)
Two recurring questions seem to be raised by level 2 Phone Support
to help me recover access, Without Formatting. I refused to do it, and insisted
they walk me out of this problem.
One suggested the Parse file was corrupted. Another Seems to feel that having
once forgotten firmware & or Master Password was the problem.
I disagree, I was able to recover that time by dropping to unix prompt, once I
got in, created root user, deleted My User Account,
then Recreated it, using Same Name ) Then deleting Root Account. (for Safety)
I no longer set Firmware or Master Password, It HAS Happened since.
I'm inclinrd to believe the corrupted Parse image, for all the reasons above.
It can be recovered, without Format Or Time Machine Restore. However several different
methods were used by different tech support people, so I have Messy notes on
what the actual steps were. Due to so much back tracking & Holding, And Different
methods used by different Phone Guys. NEVER attempt to try with level 1, INSIST
on level 2 support or you will not recover. Solution seems to have been successful
Most often, after working at unix prompt, and executing various commands.
If I find the Most Efficient notes, I kept from the 1st guy, who was Very Good.
I will post them. Sorry I couldn't be more specific on the recovery steps.
I remember running: fsck -?? & mount -???? , navigating to root, and not mush else.
Good Luck

Stuck with gray screen during update (firmware)

Today I completed the routine software update (firmware) on my macbook pro. During the update all I can see is a gray screen with no progress bar. It appears "stuck". Please advise!

See https://discussions.apple.com/message/24334963#24334963
Hold power button down 5-10 seconds. It will restart and all should be fine.

Downloaded iTunes update. Clicked to restart but am stuck on gray screen with an endlessly spinning wheel.

Downloaded iTunes update to my Mac mini (2007). Pressed restart but computer is hung up on a gray screen with a spinning wheel. Doesn't respond to power switch. Disconnected but returns to same screen when plugged back in.

FWIW, have a look at this user tip.

Help =( Mac got stuck on gray screen

Hi
Update went ok a couple of days ago.
Tonight it suddently got "stuck" and after rebooting it, it is now stuck on a gray screen.
Impossible to reboot from the installation disk or from my Lacie disk or from the HD.
When attempting to reboot from the Leopard installation disk, I then get a message telling me that the Mac needs to be restarted, but when I restart, I get stuck again on the gray screen with the Apple logo in the middle.
I am at a loss as to what to do.
Help, please!!! I am now on a friend's computer to access help. So a quick response from someone would be fantastic.
Anyone?

update on current situation:
i took my macbook to be repaired first thing this morning.
it is apparently a small part that is damaged and therefore preventing the macbook to reboot.
hence why the hardware test indicated that it found no problems and that when attempting to reboot from a disk or a drive, it finds them, but cannot reboot from either.
the part should be here tomorrow afternoon and i should get my macbook back either tomorrow or thursday.
apparently, it is nothing serious and no loss of data should occurr.
but they will only know this for sure once the part has been replaced and they can actually reboot it. they say this is not linked with the leopard update.
just sheer bad luck from a defective part.

MacBook Pro won't start up. Gets stuck in Gray Screen

Ever since two days ago when I did a regular systems update of iLife, iWork and a bunch of other updates to my MacBook Pro, the thing wouldn't restart. It gets stuck in the gray screen and no apple symbol shows up.
Just on a chance, I turned the power off and the MacBook Pro continued to start up, and was fine. I'm wondering if because I didn't update to Leopard yet, there might be a conflict due to my recent updates, or maybe one of my peripherals is causing it to stall in start up? I have my iPhone dock, External Hard Drive, Apple LCD Screen, Mac Mini Style Hub, and HP printer plugged into the MacBook Pro.
This has ONLY started to happen when I recently updated in systems updater. It's happened 2-3 times. After I send this I will check it again, but I think I will have to AGAIN start using only the battery source and not plugged into the outlet.
Maybe installing Leopard will fix this problem? I am getting it fedexed in a day or two.
What could it be?
Help!!
Thanks,
Lainey

I haven't received Leopard yet, so haven't tried to install. It's when I use Software Updater. the last update is what I think is causing the stall.
I tried something though. When it stalled this last time, I pressed the LCD on switch on my 17 inch monitor, and then the start continued. Is there maybe a driver update needed for the 17 inch monitor now that I updated some softwarevia Software updater, or is that just me being paranoid?
Maybe the software updater installed stuff that needs Leopard to run properly. Once I install Leopard, I'll let you know how it goes. MEanwhile, I am going to try restarting a few more times.

Imac stuck at gray screen at the start

Stuck on gray screen on warm restarts

I just wanted to add a data point to the problem of getting stuck gray screens with warm restarts.
My Mac Mini 3,1 (early 2009) started arresting at the gray screen with the logo upon warm restarts. If I shut down entirely and waited for a while, or if I unplugged the mini for a few seconds, it would start up fine and work normally. I tried replacing the hard drive (it was due for a bigger one anyway) and installing Mt Lion from scratch; but that did not affect the problem one bit.
I took the Mini to the local Genius Bar, and when we couldn't reproduce the problem, I noticed we were using a VGA cable with an old monitor. My Mini was hooked up with a Monoprice mini DVI to DVI cable at home. When I got home, I swapped the Monoprice cable out and replaced it with an Apple mini DVI to DVI adaptor connected to a standard DVI cable, and my Mini runs like new. It also runs 10-15 degrees Celsius cooler. I postulate that the Monoprice cable was stressing the video chip and causing other problems.
I'm bummed because I was all set to get a new Mini or iMac.
I hope this helps someone out there.

I got a message from Monoprice's returns department verifying my shipping address; so I guess the lifetime warranty applies. I'll see if the problem goes away with a new Monoprice cable; but the computer is running like a champ right now.
I'm not totally happy about that. I was getting pumped about needing a new computer; and how I'll have to put off the upgrade until the current Mini won't handle OS updates.

Early 2011 MBP stuck on gray screen, verbose mode shows SMC error too

Hi!
I have and early 2011 MBP, running on OS 10.7.5 is continuously stuck at grey screen upon start-up.
I tried the steps as mentioned in Mac OS X: Gray screen appears during startup - Apple Support article apart from reinstalling OS X. The laptop started after every step, but then stopped again. I tried SMC update, that also worked for once, and on the second start up I ended up with a blue screen. During a later attempt, it worked again for a while, but ended with a distorted graphics after 15 mins. AHT (short version) doesn't show any hardware errors. Now the laptop doesn't go further than grey screen at all, and after a minute or so there's a heavy fan activity. The verbose mode also shows and SMC error, smc: : smcinithelper error: mmio regmap ==null - fall back to old smc mode (AHT Shows SMC version as 1.69f4)
What do you advise?

Try this:
Reset the SMC and the NVRAM:

Then try a safe boot:

Any success?

10.6.8 update stuck on blue screen... 4 hours and counting

Upon selecting automatic software update my system seems stuck on blue screen with spinning grey gear. How long should I tolerate this (going on 4 hours now) before attempting to do something?
I can access the hard drive of this computer from others on my local network and am able to copy files from it. I'm wondering if I should try to grab all that is valuable to me before anything worse happens.
Advise?

If your data is not backed up copy any important documents you can from your Mac's startup drive.
Once you are done copying your data, use the power switch to turn off your Mac and disconnect everything except a wired keyboard/mouse and monitor. Start up in safe mode by holding the shift key down right after you hear the startup chime. Keep holding down the shift key until you see the Apple Logo and spinning gear.
Mac OS X: Starting up in Safe Mode Mac
OS X: What is Safe Boot, Safe Mode?
Safe mode will do some maintenance routines and checks/repairs the disk if needed so it will take quite a lot longer than normal to boot. Once your Mac boots restart normally. It will take a little longer than normal to boot but not as long as booting in safe mode.
If things don't work as expected install the Mac OS X 10.6.8 Update Combo

4s bricked after trying new update, stuck with black screen with apple logo how can i fix this

Update bricked my 4s
phone , stuck with black screen with apple logo ..
how can I fix this

Greetings r1042,
Welcome to the Apple Support Communities!
I understand that your iPhone is not booting up past the Apple logo. In this situation, I would recommend working through the troubleshooting steps located in the attached article.
If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support
If your device gets stuck during startup
When starting up, you might see the Apple logo or a red or blue screen for a long time, or your device might restart again. Try these steps:
Make sure that you have iTunes 12 or later on your computer.
Put your device in recovery mode.
When you get the option to restore or update, select Update. This will reinstall iOS without erasing your data.
Have a great day,
Joe

Stuck on gray screen on install of snow leopard server....

6 core 3.3 ghz, Mac Pro, running snow leopard server.
I need to change from my current RAID5 config to RAID0. How I wanted to proceed;
1) make TM backup
2) reinstall 10.6 server from installer disk (not the machine specific one, as I lost it, and apple made me pay for a new copy even though Im still under applecare)
3) change RAID config during install
4) repopulate from TM during install
Unfortunatly.....
The installer never got past the initial apple gray screen (no time bar either).
So.....
I tried cloning the installer disk to an external usb, and booting from that.......no luck
I tried removing all my drives except 1 (3 were in raid 5, 1 was stand alone), and trying to boot off both the the usb and the dvd, no luck.
(note, when I hold down option during startup, it does see the dvd installer in the drive, and it allows me to boot from it, it just never starts the installer)
Then I tried...
Cloning a minimum version of my current system onto a usb, booting from that, then formatting my 4 drives and RAIDing them to RAID 0.
Then booting the installer.....no luck
Then I repopulated the new RAID0 array with my minimum system version, so that I had an OS back on the RAID array
Then booting the installer......no luck
(and reset PR all the time....)
I do not want to go through and drag and drog hundreds of folders from TM to the new system.
I want to resintall from scratch, and have the installer repopulate from my TM backup (because that's its job!)
any suggestions?
(frustrated)

"Look at that article. It says if you have a Mac OS X 10.6 running on your Mac's Hard Drive, and double-click on Install Mac OS X Server Icon on the DVD, it will give you a INSTALL button instead of a RESTART button (beacues you have a LATER version of Mac OS X already Installed on the Hard drive)."
Yes, that's what I see now, and it hangs as stated.
Even if it says "Install" when you click "Install" it then goes on to inform you, that it will restart to begin the installation (where it hangs)
BUT I also tried WIPING the entire system (no OS whatsoever), reformatting the drives using a bootable usb (so NO OSX running on my Mac's hard drive), and it still hung.
The bottom line is, no matter how you install, it has to restart the machine in order to unmount the startup disk, and boot from the DvD.
Booting from the DvD, makes it hang
"Do you have your "bare-bones" Mac OS X fully updated to 10.6.8? If not, I suggest you do that first."
Yes it is.
