My retina display mbp is stuck on gray screen during latest update

. No progress bar. Is this normal, how long does it take to update?

If it's stuck there more than 15 minutes I would suspect a problem, likey with a third party at boot kernel extension file.
You can reboot holding the Shift key down (wired or builtin keyboard) and that will enter Safe Mode minus the outdated kext files.
A better option would be to do the #8 Reinstall Just OS X + Software Update method here.
..Step by Step to fix your Mac
Once you machine is booted, check for any third party software that fails to run, then check for updates/issue on the developers site and when to expect a update before reinstalling the non-working programs.

MacBook stuck at gray screen during start up

Lately my 2008 model MacBook has been freezing up. When I shut it down, it starts up just fine, however, the last two times I've shut it down, it gets stuck at the gray screen during start up. The first time, I was unsuccessful with a Safe Boot, however I was successful using CommandOption+PR to reset my NVRAM/PRAM. It has been working fine for the past two days, but it froze again this evening. I tried Safe Booting, removing peripherals, resetting the NVRAM/PRAM and I even was able to repair the disk and the permissions, but still, I am unsuccessful during a start up.
When I did try to "Perform an Archive and Install installation of Mac OS X", it said my computer was not able to install 10.5 (I run 10.6) because it did not meet the system requirements.
As a final effort, I tried doing another SafeBoot, this time viewing the status. It has been stuck at a console screen that reads "disk0s2: media is not present...." for about ten minutes now, if that helps at all.
Any advice on how to fix this would be highly appreciated. And yes, I have read the Gray screen article

Your hard drive may be damaged or requires reformatting. You might try this to start:
Repairing the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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. Now restart normally.
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.
If you still are unable to restart or if DU cannot repair the drive or the SMART status is not "verified" then you can try reformatting the drive to see if that fixes the problem, otherwise you will have to replace the drive.
Extended Hard Drive Preparation
1. Boot from your OS X 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 Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
And, you cannot do an Archive and Install of Leopard over a Snow Leopard installation. You have to reinstall using the Snow Leopard installer.

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.

Macbook stuck on grey screen during software update reboot

After I run my software updates, it tells me that I need to reboot to install them. However, it gets stuck on a grey "Software Update" screen. It will not allow me to force quit. I've even left the computer on overnight, still there. I have to do a hard shut down. Also, when I do boot it up and continue normal activity and attempt to do a normal shut down it takes me back to that grey Software Update screen. Even if I didn't try and run it for the day. Each time, hard shut down.
I took it to Geek Squad 2 weeks ago for this issue and a kernel error. They shipped it to Apple repair. They fixed the kernel error, but I cannot get this to update or remove the grey screen. I dread having to take it back in...but my warranty will expire next month. Any ideas? I am not getting the continuos spinning circle at that page or the Apple logo that I've read about.
Thanks!

HT4889 Problems with migration assistant from 2010 MBP to Retina Display MBP using ethernet

I am trying to use migration assistant from my 2010 MBP to my Retina Display MBP using ethernet (with thunderbolt adapter) however it can not find the computer. It only finds it over wifi. I have updated all my software on monutain lion. Can anyone help?

I know I am not answering your question but I would try to use FW800.
I imagine the 2010 MBP does not have TB or it whould be better a TB direct connection.
Last try: have you managed to use migration assistant "both ways" ? I mean you can manage to use it from each of the 2 connected Macs.

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 in gray screen

Im stuck in gray screen at startup with a spinning gear. Dont have a os disk, worried because i have tons of pics that are not backed up. :"O(

HI
My Macbook Pro also struck in gray screen at startup . I have Mavericks OS on the MAC. Don't have OS Disk.

Hi apple, I have the new ipad with retina display, i have however cracked the screen pretty badly. I was just wondering how much it is to replace this ipad with the same one. It is a 32gig. Thanks

Hi apple,
I have the new ipad (4th gen) with retina display. Yesterday I cracked the screen pretty badly. I was just wondering how much it is to replace it with the same ipad. I have the 32gig ipad with wifi.
Thanks

The iPad will be $329 AUD if replaced via postage service or $309 AUD if replaced at an Apple Store. Yes they will give you the replacement and take your old iPad so I would suggest if you can back it up to iTunes so that you can restore the back up to the replacement.

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?
http://support.apple.com/kb/HT1455
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.

Mac Pro stuck on gray screen after installing software for a new keyboard

I am having a huge issue with my very important work computer! For a few weeks, my Mac has been freezing on the gray screen during start up. Since I had two external hard drives plugged in, I would unplug one of them and the Mac would always restart correctly once one was unplugged. Well today I was installing software for a new keyboard and the mac prompted me to restart. Once I restarted, the gray screen came up again and no matter what I did it would not start up correctly again. I tried unplugging everything except the keyboard and monitor and nothing works. I tried ejecting the crash-causing CD with the keyboard using all of the commands I found on this forum board and nothing worked. I saw forums about manually ejecting the CD by pushing a pin-hole but I cannot find that pinhole anywhere! Then again, the CD might not even be the problem but since the computer gave me the gray screen of death right after using the CD I am thinking that it is the problem. I use this computer for editing a TV show and creating websites so there is a ton of files on it and I need to get it up and running again ASAP. Any suggestions would be appreciated and I am sure by now you can tell that I am not a Mac expert so please dumb it down for me. Thank you!!

I would start by breaking your thoughts and sentences out from one long paragraph.
Start at the basics.
Always have backups.
One at least that is a spare boot system you can use.
Clone your system. SuperDuper does a great job for only $29
Boot from another hard drive or last OS X DVD
Repair your drive with Apple Disk Utility along with 3rd party disk maintenance and repair
Hold Option key until the boot manager, then hold mouse to open optical drive.
You can hold mouse on startup and it will eject also.
Hold and continue to hold Shift key during startup to repair the boot drive in minimal fashion.
What device and driver? hint: never use CD, just go online as the CD is usually out of date anyway.
Fill in Mac OS X version and more about hardware would help in posts and in your profile signature.

Is 256 gb flash storage enough on the retina display Mbp?

I am going to college and can't decide between the baseline 15 inch MacBook pro with 500 gb hard drive and the baseline retina display. While the speed and slender design of the retina display are certainly appealing, I am concerned that the 256 gb of flash storage will not be enough in the long run. I mean, I will not be running the entire adobe suite, but I will definitely be running the entire Microsoft office for Mac suite (word, excel, powerpoint, and outlook),as well as the adobe photoshop cs6 extended program. I will also run iTunes with a library of roughly 800 songs, as well as various apps that may exceed 30 to 40 gbs potentially. I will also store some photos and movies on there, and I am looking into getting an external hard drive to backup my computer to. So for your basic college student that will mainly be using office, surfing the web, and using iTunes, is 256 gb enough? I also am seeing a lot of complaints about defective retina display computers on the discussion boards, and I was wondering if those are making up a large portion of retina displays being sold.

It feels to me like Apple intended the Retina MBP for users who would be using cloud storage a lot more than people have in the past. For example, if your media is purchased from iTunes, it stays in the cloud instead of taking up space on your hard drive, so you don't need as much onboard storage.
I've often wondered if this was wishful thinking on Apple's part, hoping that people would start using iTunes and iCloud more, and it remains to be seen if that will be the case. I really think the Retina MBP was designed for that.
I'm not trying to discourage you from getting one. It's more like, I'm hoping these thoughts (and I may be wrong), will help you make a good decision based on your usage habits. It's an awfully large investment, after all, and one that you'll have to live with for a long time.

Retina Display MBPs have 20% lower brightness than non-retinas?

I've been waiting until going off to graduate school to make a new computer purchase, and when I saw the MBP with Retina I thought that this was the computer for me. I do a ton of photography work, and Aperture is my lifeline, so the retina display really seemed like one of the best things that could happen to a Mac.
I went into the Apple Store yesterday and left extremely disappointed, however. The new MBPs were stupid fast and truly a work of engineering art, but there was one thing that I just could not shake...
The screen seemed dim at max brightness.
Because the laptops were locked down, I asked a customer who had last year's model of the MBP to place it side-by-side with the Retina one at max brightness. While the retina display was clearly sharper and far more vivid, it was significantly dimmer than last year's model.
Sure enough, a google search showed that the retina display uses 4x the battery life of a non-retina display because it has to push 4x the pixels. To conserve battery, Apple lowered the maximum level of brightness that the display can reach by 20%.
This is a huge bummer (though understandable). I often work with my screens at maximum brightness. In the Apple Store, with the powerful fluorescent lighting, light color interior design, and the huge windows letting in a lot of light, it really emphasized how dim the retina monitor appeared. While some people argue that the retina display's superior black levels make up for this loss in screen backlighting, I would have to respectfully disagree.
I was wondering if there is any way that this limitation on screen brightness is an artificial software limitation imposed by Apple? If yes, and there is a workaround to force the brightness to 20% higher to match last year's MBP model, I will instantly buy the MBP with Retina (whenever one gets in stock!). It is truly an incredible machine, but for my purposes it is severely hindered without a screen that "pops".
I am not too familiar with how the technology in a monitor works to create brightness, so perhaps this is a hardware limitation. In that case, I think I will consider an MBA... But I'd really rather the superior hardware, especially the dedicated graphics card for when I'm pushing the computer on a multi-monitor setup.

I think one of the reasons is a hardware limitation. Look at these pictures of various LCD screens and resolutions under a microscope and compare the iPad retina and iPad 2.
http://www.anandtech.com/show/5689/the-new-ipad-retina-display-analysis/2
Notice how much of the surface area is actually black compared to the tiny pixels, and how the tiny pixels just can't be as bright as huge pixels. Why is this? While four green Retina pixels are roughly the same size as one non-Retina pixel, the hi-res four pixel combo has to be darker because in the same amount of space, the hi-res combo must have black grid lines occupying a significant part of its surface area.
It has been said that because the amount of black grid also goes up as the number of pixels goes up, the Retina display requires more power to push the backlight through the black grid and brighten up those tiny pixels to the same level as the older bigger pixels. It looks like part of the problem is inherent in LCD technology itself, and if there was another practical mass-production technology that could be used that could eliminate the black grid altogether, brightness could go up by quite a lot.
In one sense I won't mind a dimmer display, because when working with images, modern LCDs are often too bright if you're trying to calibrate to paper brightness levels and so I often run my MBP below maximum brightness. But when working next to sunny windows, trying to overcome gloss reflections and glare, or general use, it's nice to have a bright screen.

About to move from Windows to Mac. Considering purchasing retina display MBP 15" with dual boot system as I need some of my programs. How is the display in windows for photoshop?

Has anyone got any thoughts or have you yourself purchased the MBP with Retina display and added the dual boot system with windows?
I desperately need to update my gear and want a MBP.
I'm a full time photographer at my local paper and freelance photographer - use computers A LOT, and only use windows. I've experienced mac and know I prefer it, the way it runs pleases me a whole lot more and for the amount i'm processing/working I need something that will keep up.
With 12 years of photoshop gear loaded up for all my photo processing etc, I'm wanting to add Windows and have use of both. Windows would run photoshop that I had already purchased some time ago - question is, how will it run? what will the display be like running Windows on Mac with the retina display?
I use CS4 at the moment and can't afford to upgrade to CS6 just yet, plus i'd waste a lot of what I already have by starting again on Mac. I'd use Mac for everything else, need the use of Windows for portions of what I do.
About to head to Canada and want to get set up for the road. Any help is much appreciated.
Thanks heaps!

There are some drawbacks, running Windows 7 (only) on a Mac via Bootcamp yields less than stellar results, especially with the Retina display.
And of your traveling, the Mac's high power needs (especially the Retina display) and lack of removable battery are going to be a serious issue. The Retina display is glossy, not ideal for viewing on the road and in varied environments.
CS4 won't run on the OS X version that comes with a Mac, so your looking at purchasing CS6.
Support for Windows is more widespread than for Mac's, also if you ever need to redownload OS X to fix a issue, requires a fast reliable Internet connection of the broadband kind.
If your running Windows on your Mac, you can expect to be on your own and not get support as easily as if you were running it on a regular PC.
If you can't afford to keep up with CS upgrades, then you shouldn't be considering a Mac because there are more paid upgrades on that than on Windows 7, it's like a annual nightmare.
IMMO your still better off on a decent, 1920 x 1080 res, matte screen, removable battery (with extras), Win 7 Pro i7 machine (Pro+ runs XP programs) which will stay like it is and get security updates until 2020.
OS X changes every year and if you don't upgrade, + all your third party software, then about 3 years later your left behind for updates.
Also you will have to buy Win 7 to run on your Mac, the OEM disks won't work.
If your trying to budget, then a Mac is certainly not for you.
