• Mac Pro 2008 No. Startup Manager Access/Gray screen on startup

  I'm in a difficult situation and hoping a Ninja Mac can give a helping hand.

  Had a RAM issue (is no longer recognized a pair of memory modules in a 2008 Mac Pro, El Capitan), and among the troubleshooting steps, I did a PRAM reset (press / hold down ALT + CMD + P + R during startup) just to see if it could resolve. Unfortunately, the Mac would not start in front of a gray-white screen with a flashing icon of folder/question mark. Returned never me to get there.

  I had read that resetting the PRAM the disc start, among other things, may need to be reset afterwards, and this seems to be the case. Looked this solution and kept diligently press Option key during startup. This time, no folder icon, instead a sensitive cursor, but nothing else. Gray-white screen only, no boot manager to select the startup disk is suitable.

  I also tried the following...

  1. Starting in the Diagnostic Mode... Gray screen.
  2. Restore/recovery... Gray screen.
  3. Reset the SMC... Gray screen.
  4. Enter Safe Mode... Gray screen.

  OS (and apps) on flash PCI cards. All files are on hard disks in the 4-Bay, as well as a player flash remains connected to a (used as a scratch of PS) free SATA port. So I can't really share, but I wonder if I shoot all readers it would require a search for another source?

  I create an El Capitan USB boot (currently copy with createinstallmedia), but don't expect that it will offer what anyone else that its use is based on access to the Startup Manager at startup..., that I can't do. There are the graphics on the screen (missing folder icon, mobile mouse cursor) so can not imagine a video problem.

  Looking forward to enter here.

  Success!

  I created a USB bootable OS X installer using these instructionsand createinstallmedia. After some messing around with the Terminal syntax USB was ready to go. My concern, however, was that the operating instructions required by selecting the drive of the Startup Manager... which I could not access.

  With the USB stick plugged in I started to turned on the Mac while pressing the key OCCUPIED Palestinian territory and this time, the selection screen pops up showing just the USB key for installation of El Capitan. Got that we open and instead of installing I chose Startup Manager in the installation menu bar, took my normal OS drive and rebooted. Back in business, no problems.

  This put aside, although I understood that reset PRAM would also require reselect startup disk, I don't have a hot clue why did not appear the Boot Manager - or any other useful diagnostic. If someone could throw some light here would be appreciated.

• Satellite L750 - gray screen at startup

  Hi guys,.

  I have Toshiba Satellite L750 slightly less than 2 years. He developed intermittent problems, when starting it arrives with white/grey screen and disappear when the login screen is ready. Sometimes touching the upper left part of the disappears from the screen it. Other wise I have to keep restarting. I have checked the cable connections between screen and motherboard, and they seem good.

  I have also connected my laptop to an external display while it shows the gray screen and the external display. The screen is not cracked or the other.

  Help, please. Thank you

  Googling around you can find a lot of discussion on various forums on similar problems and many different explanations why something like this can happen. On this virtual path, it is not easy to say what may be wrong with your laptop, but it is certainly the unwanted material.

  In my opinion you should either continue to use your laptop until it can be possible and later when the issue gets worse search solution or contact the nearest service Toshiba and ask for help.

  Guarantee is generally of 2 years (depending on the country) but if you opened it on your own guarantee is canceled now.

• 10.11.2 gray screen on startup, then...

  .. Press start briefly - black/standby screen, press start up briefly again and we are running.

  Last update downloaded from the on-screen prompt. Does not seem to load correctly, stuck in the gray screen. Shut down and reopened in SafeMode (C) and the message to the 'installation complete' screen and open to my start up screen ok.

  Stop and restart, get the chime and opens it to Apple screen and bar. Bar fills half way, gray screen and sticks. Back to the first sentence!

  I have to start panicking?

  You can start and connect in safe mode, but not otherwise?

• A gray screen at startup - no solution doesn't work?

  Since I upgraded to El Capitan my iMac has been a nightmare and it was fantastic before!  This week it stopped loading altogether; If I start it normally, it brings up a loading bar then gets just stuck to the end, if I load in SafeMode it show the loading bar then once charged him will just grey screen.

  So far, I've tried all the solutions I could find online, reset the PRAM, reset the SMC, repair disk and first aid under disc utilities at the start in recovery mode, reinstall the OS X (no not work - got stuck on 0 seconds to go).  I am at my wits end and have absolutely no idea what to do to solve this problem!  Any ideas?  Thank you.

  Hi lolsapple, do you have an another startup boot disk? If so try to start from that, download and run EtreCheck.  It is a diagnostic tool that is very useful for us to find problems. It will also give us additional specifications on your Mac. After his execution after the logfile here. It will never contain any personal information.

  You have an another startup boot disk?

• Only gray screen at startup

  I got the Captivate installed for several months and it worked fine. But now, if I try to start it, I first see the screen start and after the program window is just gray. I can still play it down, but I can only it out via the Task Manager
  I already updated my Flash drive, reinstalled Captivate and used the repair function. None of this has helped.
  
  I would be glad if some of you could help me because I have to finish a few films which are due next week. :-(

  Thank you all for your advice and suggestions!

  None of them could really help my out of my misery, but now, I found a solution (sort of). I used Windows system restore and restored at a checkpoint about a month ago. Captivate seems to work very well now, but I really cannot know exactly what the problem was.

  I will now end my movies before doing anything else...

• Slow startup after installing the SSD because gray screen

  I just installed a Samsung Evo 500 GB SSD in my Macbook Pro 2010. I went to start and it starts very slowly due to a gray screen just sat there for about 30 seconds and then it shows the apple logo and it takes another 15 seconds to load. The gray screen did not appear before installing the SSD but the Apple logo did take longer to load with the HARD drive. I used SuperDuper to clone my my SSD HARD drive and installed the SSD and it starts normally. The only issue was the gray screen. I've heard that I need to go into system preferences and select Startup disk, then my boot drive, but there is no choice. Help, please.

• Blank gray screen on wake?

  So I am using this Mac mini (late 2014, 2.6 GHz Core i5, 8 GB memory, 1 TB HDD, OS X El Capitan 10.11.6) for almost a year now and I'm having a serious problem with waking up from his sleep recently. If I let him sleep long enough, I get a gray screen on wake. No progress bar or the other and it can go up to a half hour without doing anything. I turned off the Hibernate using pmset just in case, and the problem is still happening. Happen 3 - 4 times so far.

  Moreover, some of the keys on the gray screen gives an error sound system. I don't know if this means that it is a problem with OS X or not, but I'll bet it is, as I ran Apple Diagnostics and it showed that there are no are no hardware problem. I'm really confused now. Has anyone else experienced this?

• Only get a gray screen after upgrade of El Capitan. What can I do?

  I tried to install an upgrade, but only now have a gray screen.  The installation seems to have stopped half way through.

  Please take each of these steps that you have not already tried it. Some of them are not applicable to your model or your situation. Stop when the problem is resolved.

  To restart a computer is not responding, press and hold the power button for a few seconds until the unit turns off, then release, wait a few seconds and press again briefly.

  Step 1

  The first step to respond to a startup failure is to secure data. If you want to keep the contents of the boot drive and you have not already at least a current backup, you should try to back up now, before we do anything else. It may or may not be possible. If you don't care the data changed since the last backup, you can skip this step.

  There are several ways to back up a Mac that is unable to boot. You need an external hard drive to store backup data.

  a. starting the partition recovery or an hour Local Machine backup volume (button option key at startup). When the OS X Utilities appears, launch disk utility and follow the instructions in this article to support. You'll be 'restoration' the boot on the backup volume volume.

  (b) If step 1 fails due to disk errors, and no other Mac is available, then you may be able to save some of your files by copying them in the Finder. If you already have an external hard drive with OS X installed, the start of it. Otherwise, if you have access to the Internet, follow the instructions on this page to prepare the external hard drive and install OS X on it. You will use the installation program of recovery, rather than download it from the App Store.

  c. If you have access to a Mac, and it work and have both the non-working Mac FireWire ports or stroke, start the Mac non-working in target disk mode. Work Mac to copy the data to another drive. This technique will not work with USB, Ethernet, Wi - Fi or Bluetooth.

  d. If the internal drive of the non-working Mac is replaceable by the user, remove it and climb into a docking station that is pregnant or an external drive. Use another Mac to copy the data.

  Step 2

  If you have booted from an external drive, make sure that the internal boot volume is selected in the pane of the system preferences Startup disk.

  Start in safe mode. Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. If you do not see the words "Safe Boot" in the start screen, you did not start in safe mode. Ask for additional instructions.

  Safe mode is much slower to boot and run as normal, and some things don't work at all, including the networks without wire on some Macs.

  The login screen is displayed even if you normally connect automatically. You must know the password for the connection to connect. If you have forgotten the password, you will have to reset it before you begin.

  If the startup progress bar gets stuck for more than a few minutes, or the system stops automatically when the progress bar appears, the boot volume is corrupted and the player is probably defective. In this case, go to step 9. If you have another problem with the player, replace it immediately.

  If you can start and log in in safe mode, empty the trash and then open the window of info on the boot volume ("Macintosh HD", unless you have given it a different name.) Make sure you have at least 9 GB of space available, as shown in the window. If you do not, copy as many files as necessary on another volume (not another folder on the same volume) and delete the originals. Deletion is not complete until you empty the trash again. This, until the space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)

  If the boot process hangs again, the problem is probably caused by third-party software you have installed. Ask for additional instructions.

  Step 3

  If the startup process stops at a gray screen together with a mobile cursor, then the logon dialog box may be active but not visible because of a bug. You may be able to connect by using the arrow keys or the cursor to select the password field and type your password as usual.

  Step 4

  Case of failure of step 3, the boot volume can be complete. If you saw previously implemented guard space drive is low, it is certainly the case. You might be able to start in safe mode , even if you cannot boot normally. Otherwise, boot from an external hard drive, or well technology for step 1b, 1 c or 1 d allows to mount the internal drive and delete some files. According to the documentation from Apple, you need at least 9 GB of free space on the boot (as shown in the Infolog) for normal operation volume.

  Step 5

  If a Mac desktop (without the built-in keyboard) crashes on a gray screen together with a mobile cursor, the keyboard may not be recognized. Hold down the button on the side of a wireless Apple keyboard to make it discoverable. If need be, replace or recharge the batteries. If you use a USB keyboard connected to a hub, connect it to a built-in port.

  Step 6

  Sometimes, a startup failure can be solved by resetting the NVRAM.

  Step 7

  If there is an integrated optical drive, a disk may be stuck in there. Follow these instructions to remove it.

  Step 8

  Press and hold the power button until the unit turns off. Disconnect all devices wired except those needed to start and remove all aftermarket expansion cards. Use another keyboard and/or mouse, if these devices are wired. If you can start now, one of the devices that you disconnected, or a combination of both, the origin of the problem. Discover that it is a process of elimination.

  Step 9

  Launch the utility disk in recovery mode (see step 1). Select the boot volume, and then run the repair disk. If problems are found, repeat until that clear. If disk utility reports that the volume is not repairable, the drive is defective and must be replaced. You can choose to tolerate such malfunction in the reader's life. In this case, delete the volume and restore it from a backup. If the same thing happens again, replace the drive immediately.

  It is one of the rare situations where you must also run repair permissions, ignoring the erroneous warnings, that it can produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.

  Step 10

  If the boot device is an aftermarket SSD, it may have an update and/or a forced "garbage collection". Instructions how to do this with a Crucial SSD of brand have been posted here. Some of these instructions may apply to other brands of SSDS, but you should check with the technical support of the provider.

  Step 11

  Reinstall the OS. If the Mac has upgraded an earlier version of Mac OS X, you need the Apple ID and password used to upgrade.

  Step 12

  Do as in step 11, but this time clear the disk utility boot volume before installing. The system should automatically restart in The Migration Wizard. Follow the prompts to transfer data from one Time Machine or another backup.

  Step 13

  This step applies only to models that have a battery logic-board ("PRAM"): all of the Mac Pro, MacBook with a removable main battery and a few others (models not updated). A flat battery logic-board may cause a boot failure. In general the failure will be preceded by the loss of the system and boot disk clock settings. Refer to the user manual for replacement instructions. You may need to take the machine to a provider of services to have to replace the battery.

  Step 14

  If you get this far, you probably deal a hardware failure. An appointment of 'Genius' to an Apple Store, or select another authorized service provider.

• White gray screen of death

  A recently obtained a Rev B G3 iMac, updated the firmware once so I could try OS9, and two days in the HARD drive made this death rattle and crashes hard

  Wonderful.

  So I order little ram from OWC (2 x 256 MB)

  A 128 GB SSD home (very disappointed because they include an adapter + SSD and it is not just a SSD IDE or made to be more integrated.)  Too expensive for what it is),

  and a new battery of LANDAU

  Repinned new fan Cooler Master 92 mm to replace the old (works perfectly)

  Starts and... gray screen.  No folder, nothing.

  Try resetting the NVRAM with Command-Option-P-R and he did once successfully, but no change in the results.

  Try Open Firmware with Command + Option + O F and it will start but the CRT remains off and the power light stays orange.

  NVRAM later tried and he won't even be deceived, forced to do other ways to become more involved.  Still no change of result

  Try holding Option at startup, nothing.  Tried holding C at the start, nothing.  Tried holding O during the boot since I heard some Macs to bring up the boot with it instead, Manager nothing.

  Tried 2 other keyboards, nothing.

  I even tried 2 other internal drives CD/DVD slim just in case I got fried somehow the original drive 24 x CD, nothing.  External hard disk is not no longer works.

  Recognizes to all readers and keyboards, powers, them and the readers try not seeking, still no results.

  going to try different hard disks and resetting the ram, replace it with the original of the ram, etc., but hoped someone had an answer for this miracle.  Hope that I didn't somehow make fried logic board or screw up somehow.

  I was hoping to keep this one close to stock (at least that I found one of these Harmoni 600 mhz cards miraculously) and a slightly less desirable another iMac G3 as my project to empty out and replace internal components with a Mac much more modern (Apple would be cool with this right?  Wouldn't a Hackintosh I think)

  If there is no operating system on the new drive, it won't start (with the exception of the optical drive with a Mac OS installation disc).  Startup Manager is accessible by pressing the Option key during the boot, not the O key. I don't remember if the iMac G3 tray-loader has Startup Manager.

  I think you've changed too much at the same time, so it is difficult to find the change that caused the problem.  Try to put the original RAM until make you it work.  Some of these original iMacs do not work with the RAM (unofficial) max of '2 x 256MB.'  Put the original optical drive, if it was working before.  If you have a standard IDE hard drive that is less than 128 GB, it would be a good idea to install it to rule out the possibility of an incompatibility with the SSD + adapter.

  What installation disk of Mac OS that you are using the optical drive to start?

  NOTE: Once you are able to boot from a Mac OS installation disc, the iMac G3 tray-loader requires the startup on the internal disk drive to be on the first 8 GB of disk space.  Due to the older IDE used in these iMacs controller, only the first 8 GB of disk space are available during the boot sequence.  After starting (when the full operating system takes over), the iMac may access up to 128 GB.  You need disks larger than 8 GB partition as the first partition is part of the first 8 GB of disk space.  A security dimension to the first partition is about 7.5 GB, with the 2nd partition using the rest of the disk space.

• iMac G3 tray charger stuck on the gray screen with question mark flashing folder

  I recently bought an iMac G3 (charger tray, 333 MHz, M4984) and when I try to boot from an OS installation disc 10.3, there will remain only blocked on the gray screen with folder flashing with the question mark. Not only it does not maintain the keys C or Option, but it will not start up any combination of keys, such as resetting the PRAM or the NVRAM. It just starts and stays on the screen with the flashing folder does nothing. It CAN read the keyboard, because I can turn on the computer with the keyboard, it just won't start to the top of any disk or any combination of keys. Any ideas on what could be the problem? I just replaced the hard drive, but it was the same before I replaced the hard drive as well. In addition, the iMac had apparently OS 8.6 installed on it when it came, and I think I need to move to OS 9 and do a firmware update before you install OS X (correct me if I'm wrong), but I can not do because the iMac does start not in general of any combination of keys. Thanks in advance, any help is appreciated.

• Starting problem with the gray screen on iMac

  Hello everyone

  I'm a bit puzzled with a problem I'm having with my iMac 27 "a model late 2009, bought in early 2010, I had built at the time with 8 GB ram, 2 TB HD and fastest i7 Quad core processor available at the time.

  I'm running El Capitan, and all wise OS is perfectly up to date.

  The other week, after a systematic restart, I have a gray screen and little else.  Another reboot and everything was "normal", so I did not concern me unduly.

  Today, after that the Mac had been idle for a time during a call, the screen fell asleep as usual (I do not SLEEP the computer itself), but during his return and touch the SPACEBAR and key "ESC", the screen remains black.

  So I made a forced shutdown and restart.

  I get the screen gray and normal startup (no other sounds) chime followed by the apple logo and the startup progress bar.  He gets to halfway through the long, and then instead of bring to the top of the login page, it's just going to a gray screen Uni.

  So I restarted in safe mode, OK and ran disk utility a couple of times - at the first crossing, he noted, there a problem with the map of partition which can cause problems starting, but on the second passes and the following, everything has been noted to be OK - and the SMART status of disk has been verified.

  After a reboot - the same question as above - of carillon, gray screen with the apple logo, progress bar and then just a gray screen.  I did another secure boot and re-run of disk utility, rebooted into recovery mode and run disk utility.  And again, no problems reported.

  Another reboot and the issue was always there.

  So this time I rebooted into recovery again mode and downloaded a new installation of El Capitan.

  Unfortunately, there is no set - it is always start on a gray screen after the startup chime, the apple logo and progress bar.

  I have also removed all my account account startup items and disconnected all USB devices.

  I'm a bit lost for what to do next to be honest!

  Is there anything else I can do software wise, at home, or is it time for the repair material re shop perhaps?

  Thank you very much for your words of wisdom and support

  Kind regards

  John... :-)

  John here again: :-)

  Just a quick update which may help to determine what the problem is: I restarted in safe mode, after the reinstallation of the operating system was unable to initialize properly - grey screen again.

  However, as I have a home network, I found that I can not connect on the network with my MacBook Pro to the iMac, see all my files user on the iMac and even copy them across to the MacBook Pro with no problems.

  Everything on the iMac is saved via Time Machine on a Western Digital Firewire HD 3to.

  I also have uncompressed manual 'straight' copies of my music, movies, documents folders, etc, for an old time Capsule, currently acting as a bridge to my ethernet network wireless, and provide additional backup for those critical files - my music for example is ripped 350 odd CD, all legally purchased in ALAC on iTunes on the iMac - which represents a couple of months of work... lol... no way I want to lose that!

  So I'm a bit of a loss.  Disk utility reported no problem with the drive... I can boot into safe mode and recovery, but normal mode 'mode '... I always get the chime, the screen with apple logo and progress of the gray bar, then goes to just a gray screen instead of the login page.

  Help!

  My beloved Einstein had a hiccup!

  All comments appreciated and thanks again - hope this extra info helps

  Kind regards
