  • I've got nothing(gray screen, question mark folder) Please Help!

    This problem is on my girlfriend’s computer, about the same as mine, PB G4 800mhz 768mb RAM, 10.4.x
    I am a competent user and this one has me worried…
    Problem
    Last night she goes to the computer sends an IM checks her e mail, watch some tv, goes back to the computer to look something up on line and its frozen, I do not recall if the mouse was visible but I don’t think there was a beach ball. She asks me what to do I said just give it a few minutes maybe it will process through what ever it is and be back to normal. We both forget to take a look at it before bed.
    This morning computer is still frozen/non-responsive and the fans are running... Shut down by holding down the power key. I try to re-start by pressing power key, screen lights up with gray background wait wait then the folder icon comes up with the question mark in it. This gets me worried.
    What I have tried
    I have tried to get it into target disc mode with my powerbook(computer B), I start up computer A holding down the T key and the screen goes to that moving firewire icon but the hard drive does not show up on my computer B.
    I tried unplugging it, removing the battery and re setting the pram
    I tried to run the hard ware test CD, but when I hold C to boot to the CD it spins up the disc and the little hardware test folder is in the middle of the screen but then it does not load any further. I had to shut down holding the power button. Computer would not eject CD so I had to start up and use unix eject cd command, this worked.
    I tried target disc mode again.
    I tried just a plain start up again.
    I do not have the 10.4 CD at my house so I have not tried to start from that yet, but I can borrow one from grandparents this evening after work, but I am worried since it will not start from the hardware test CD that it will not start from the system CD.
    I believe I have computer A backed up from either last week or the week before( I thought about doing it this weekend but did not get to it  ), she is not backed up daily as I am. Though she said there is quite a bit of important work from this past week.
    I have no idea what to do next or what the source of the problem could be(software or hardware). I fear the worst, but hope that you can share an idea that will turn out for the best!
    Please help me fix this computer, I can play with it some when I go home for lunch and then I need to get it fixed if possible this evening because she needs some important class work and grad school applications from it!

    So is the next step to try and re-format the drive and then use super duper to copy the back up over to that drive and then run disc utility and disc warrior on it? Which specs should I select for the re format, do they have to be the same as what is on my back up drive?
    Yes, reformatting the drive is the next step. Use your Panther installer discs, choose Mac OS Extended format, and check the box to install OS 9 drivers, just in case. The "Verified" SMART status is somewhat less reliable than a "Failing" status would have been: "Failing" definitely means trouble was detected, but "Verified" could just mean nothing seemed to be wrong right at the moment when you happened to ask. So if there's any trouble reformatting the drive, replace it: you shouldn't entrust anything important to it. If all goes smoothly with the reformat, the drive probably really is OK.
    What you can do with your backup depends on how you created it. If the backup is a bootable clone made with Carbon Copy Cloner or SuperDuper, you can clone it back to the reformatted drive the same way you created it in the first place, then add the extra files that were created or modified after you made the backup. If you just Finder-copied the drive to another drive, the backup isn't bootable, and copying it back onto the reformatted drive won't make that one bootable either: OS X isn't Finder-copyable. In that case, I really shouldn't advise you on reconstructing the former contents of the drive from your backup — my only experience of backing up OS X disks is by cloning, which eliminates all the hassles of making sure user accounts, passwords, permissions, etc. are transferred correctly to the backup, and then transferred correctly back to the original disk in a restore. Nearly four years after my adoption of OS X, I confess I'm still far more mystified by many aspects of it than I ever was by the old-time Mac OS.

  • Kernel Panics, Gray screen of death, and hard drives, oh my!

    Last week, while performing multiple tasks on my G4, Safari froze up and completely locked up the entire computer. I rebooted by manually pushing the glowing power button the front of the tower. During reboot, I got the gray screen of death with the "you need to restart your macintosh... by holding down the power button for several seconds" message.
    After a couple tries and getting that exact same gray screen of death, I started to worry about all my data.
    I took both drives out of the G4 Quicksilver - one, a 500gb Barracuda Seagate (Master/bay 1), the other a 200gb Hitachi (slave/bay 2). I hooked them up to an older G4 and ran DiskWarrior and DiskUtility on both of them. The master drive had serious (>34%) fragmentation, which has since been cleaned up. The slave drive was relatively fine.
    here's my current problem:
    When I hook up:
    1. Just the Master with no jumper pins, the drive runs fine, no problems, all settings and prefs are there, etc.
    2. Just the Master with the correct pin settings, I get the kernel panic screen of death
    3. The Master with correct pin settings and Slave with correct pin settings, kernel panic screen of death
    4. If I swap the Master and Slave, and make the correct pin settings, the booting process starts and then I get a light gray screen with the "ghostbusters/do not enter" circle.
    I put the original Slave drive in an external HD firewire enclosure, and it will mount on the desktop after the original Master drive has booted up - BUT - if I have the external drive powered up before I boot the Master, I get a gray screen with nothing on it - no message, nothing but grayscreen.
    I've backed up my critical data, but would like to get these two drives back into their normal operating Master/Slave relationship that served them well for the last couple years.
    Any help greatly appreciated.

    New wrinkle:
    This morning trying at boot up, the Mac chime sounded, the gray screen w/the apple logo appeared, and then the machine sounded like either the main fan or one of the two drives spun down. Shortly thereafter, I got the prohibitory sign again.
    I rebooted and then got something completely different: a black screen with a small blinking vertical rectangle in the top left of the screen, with nothing else happening for a long time, so I manually rebooted and tried to boot into safe mode.
    Trying to boot into safe mode gave me the chime, the apple logo, and then the sound of either the fan or drive spinning down and leaving me at the prohibitory sign once again.
    Finally I option-booted to the slave drive and upon startup, received the following crash report, which might as well be in Swahili as far as my being able to make sense of it:

  • I get a gray screen with the apple logo at start up and the trackpad doesn't work

    My MacBook Pro has run fine until yesterday. It froze and wouldn't receive commands from the trackpad. I was still able to move the cursor but clicking or tapping the screen did nothing. I tried restarting but got the gray screen with the Apple logo and the spinning wheel. To get pass this I have tried resetting the NVRAM/PRAM and performing the safe boot. I also tried using the Disk Utility at start up but since I can't use the trackpad it was unsuccesful. I got pass the gray screen once performing the safe boot and restarted and everything run fine (including the trackpad) for about 20 minutes before freezing again. Now I'm back at the gray screen again and can't seem to get pass it again.
    Any advice what should I do next?

    I would back up the files and start looking at the HDD.  Open DISK UTILITY>FIRSTAID.
    Ciao.

  • HELP! Gray Screen & File Folder with Question Mark!

    Hello!
    If anyone can offer suggestions or if you've dealt with this before I would love feedback so that we can fix this problem!
    I recently converted my husband from a PC user to a Mac user (it was a happy day). A little over 1 month ago we bought a brand new 20" iMac and since then everything has gone quite smoothly, he's even said how happy he is with the switch!
    Then yesterday morning as I lay sleeping in the other room a noise similar to dial up internet woke me. I went into the office to find the internet up on the screen of our iMac, Firefox wouldn't shut down so I tried force quitting, but that too did not work. Finally I pushed the power button, and went back to bed.
    A few hours later as I went to check my email I powered on the iMac and got a gray screen. Nervous, I turned if off, and then back on in safe mode. I still got a gray screen but now with a file folder with a question mark inside flashing at me. Thankfully we're within the 1yr. warrenty so we took it back and they're diagnosing the problem....but I'm worried about the outcome.
    Has anyone else had this problem? What was the result? What caused it? We save most everything onto external hard drives (thankfully!) so it's not as if the machine was being overloaded. It kept making that weird dial up noise too... kind of a bleeb, fans running, trying to work noise. Obviously my husband isn't so thrilled with Macs now. Any help would be greatly appreciated!! Thanks!

    Welcome to Discussions - you have an intel iMac, and this is the PPC G5 forum, but even so, I would first advise you to buy Apple Care before then first year of ownership is up.
    Then, I would remind you that all electronics will fail at some point, but the exact point is unknown and sometimes is much sooner than it should be. It would be interesting to hear from you what the exact failure was, there do not seem to be many reports of intel power supply failures, that seems to have been fixed since the era of the G5s.
    The flashing question mark is usually a sign that the hard drive has failed and drives can fail at any point, yours may simply have some bad sectors; it could also be the logic board and again, they fail, but usually not within the first three years. Your machine may have been defective to begin with, it certainly doesn't sound as if you have been abusing it, so do please let us know what the ultimate diagnosis was.

  • Gray Screen o' Death

    I have a 2-yr old Intel-based iMac. I am not too computer savvy and I really haven't kept track of what version of the OS I'm using (I think 10.6.4). Last night, I got a gray screen that curtailed over the internet video I was watching and said something like "Please restart your computer" in a bunch of different languages.
    I have since learned that it was a Panic feature common to the OS. But at the time, I figured no big deal and restarted by holding down the power button on the back of the computer. When it restarted, the white screen came up and the rotating circle continued like normal, but when it loads the login screen, the screen goes black (backlight still on) and stays that way. I even can type my password in at that point and I can tell from the sounds/fan noise that I can still login. But the screen stay black. Becuse of this, I cannot pull up my panic log and see what originally caused the issue/if they are related.
    Anyone know what I should do/what's wrong with my computer? I don't have install disks nor does safe mode work.

    You suffered a Kernel Panic. These can be caused by many things however what happens most frequently is something related to the RAM. RAM can become unseated or fail, I'd start by removing your RAM (extremely simple to do if you look in your owners manual) and reseating it. If it still fails then remove attempt to figure out which stick went bad by a system of elimination.
    You can do some additional reading and troubleshooting at the following sites:

  • Intel MacBook Gray screen

    I installed new RAM a month ago and everything was fine for 3 weeks then I got the gray screen with 3 beeps at startup indicating [I think] that there is a RAM-related issue.
    Thing is - if I hold down the power key on startup long enough I get a single long tone and the machine boots shortly afterwards. I then have access to all installed RAM and everything is ducky. If I restart - no problem. If I shutdown and reboot within a short while it seems - also no problem. But if I leave the machine off for an extended period I'm back to where I started.
    So where am I?

    Reseating the RAM didn't solve the issue...what puzzles me is:
    1. that the machine fails the POST test on a RAM related issue but if I push it past the POST everything is functional??? All the RAM is available and things work fine. If the RAM is flakey how could this be?
    2. if the machine is shut down and restarted within an hour or 2 it boots fine - left overnight though and the problem is back??? What gives here?

  • Folder with Question mark on it on a gray screen.  Will not restart!? :(

    While browsing online the other night, my Macbook completely froze up on me. I couldn't move my mouse and the screen froze.  I decided to restart it but then the Macbook started making a whirring/ clack clack noise and I got a gray screen with a flashing question mark folder.  I've tried restarting it up again since then, and I get nothing.  The noise continues and I get nothing but the blinking folder with the question mark on it.  The Macbook is roughly 5.5 years old  Any suggestions?

    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. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. 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) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
    Or if you are running 10.7 Lion, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7 partition.
    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. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
    If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

  • Gray Screen Globe

    Something I've never seen before.
    I was doing a restart yesterday - changing startup disks - after doing maintenance from another bootable drive. The Mac Pro was slow to restart, stayed in Gray Screen and then a world globe popped up on the Gray screen. Didn't spin. Finally it loaded from my clone, which I did not think I had picked for startup. Did a restart on the clone and the gray screen-globe popped up again but it finally loaded.
    Here is the setup
    Model Identifier: MacPro1,1
    Processor Name: Dual-Core Intel Xeon
    Drive 1. Original HD. CLONE - It is now the clean clone of Drive 2 (Carbon Copy Cloned)
    Drive 2. Brand new. Now my MAIN HD
    Drive 3. Backup only
    Drive 4. Partioned
    A backup only
    B Bootable.TEST. Clean Apple for testing, maintenance and repair.
    I was running from the TEST volume checking the other drives. No problem. Set startup for new MAIN HD (I think). Gray screen - globe- finally boot- but from the CLONE. Restart CLONE. Gray screen -globe - boots a little quicker.
    Realized I had not used or updated CLONE for a week or two. Went to TEST drive to run Carbon Copy Cloner incremental backup. After that Clone restarted with no problem.

    The hatter wrote:
    Isolate the system from most user data.
    hatter,
    Have read your advice before and have been working in that direction. Makes good sense.
    Back to the problem. I think I may have made the wrong deduction.
    It started when I thought I set the NEW MAIN HD in System Preferences and restarted. That's when the Gray Screen>Globe came up and the Mac Pro finally booted from the ORIGINAL HD.
    I did a restart without changing the setting for startup disk and the same thing happened again - gray screen>Globe then booting again from the ORIGINAL HD.
    Then I booted TEST HD and ran the CCC incremental on ORIGINAL HD. Next I went to System Preferences>Startup Disk and SELECTED ORIGINAL HD. Booted fine.
    Could it be that the NEW MAIN HD was actually selected in the first startup Gray Screen>Globe, but the Mac Pro went to the ORIGINAL HD instead. And since I did not change System Preferences for the second restart I got the Gray Screen>Globe again because the Mac Pro was still looking for the NEW MAIN HD but had to use the ORIGINAL HD again.
    And that it wasn't the incremental CCC backup that fixed the problem, but the fact that I changed Startup disk to ORIGINAL HD after the CCC backup?

  • Question about the gray screen and wheel that keeps on spinning !

    After an update (I now have Mavericks 10.9.3) Safari froze. I tryed starting it again, nothing.
    I restarted my computer (imac early 2008) and got a gray screen,an apple logo and a spinning pin wheel!
    I could get into Disk Utility to 'verify and repair', everything was apparently OK.
    I saw a letter from a few years ago (where it was from, i can'nt remember) it suggested restarting with cammand+v
    to show where the fault was, it then scolled down a lot of witten material and stoppe at :-    'Bootcachecontrol : unable
    to open/var/db/Boot cache. Playlist :2 no such file or dirictory.     I have no idea what it means !
    Can anybody help me ? I miss my Mac !
    Best Wishes from Jonathan Sandberg.

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
    b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
    c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.   
    Step 10
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 11
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 12
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 13
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • Screen freezes on an option-less gray screen everytime on launch; re-install does not help

    I am on a Windows 7, 32 but machine. While closing one of the tabs on FF14, I got this gray screen which has been persistent since then. It was not a crash, and hence I do not see any crash reports in the appropriate folder.
    I uninstalled this version (without removing user data), and installed 16, which behaves same. I do not get any options to start in safe mode - just a semi-transparent gray screen with (minimize/maximize/close) buttons.
    Everything was running smooth, and I am quite sure it's not because of any plugins. I need to preserve my user data - how should I proceed ?
    Thanks !!

    hello dpux, [https://support.mozilla.org/en-US/questions/940393#answer-377118 from another user] we found out that this might be related to malware active on your pc. please close all firefox windows and try [[Troubleshoot Firefox issues using Safe Mode|running firefox in safemode]] (by pressing the shift key while you're starting it). in firefox safemode go to firefox > addons > extensions and remove the entry named "Codec v1.0" or any other addons that look suspicious & you have not installed intentionally. afterwards see if you can run firefox normally again...
    please also do an in-depth scan of your system with the security software already in place and/or a different tool like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & keep firefox and your plugins up-to-date in order to stay safe on the web.

  • Gray screen after Software Update

    I rebooted my G4 running Leopard, there was a "software update" that installed several updates, my hardisk may not have had enough space....when the Mac rebooted after the update the wheel kept spinning. I rebooted and got a gray screen...Tried Command-S but still get not past a grey screen. Please Help!

    Hi guido Deboeck;
    Do you have a backup?
    Did you have Time Machine turned out prior to the problem?
    It sounds like the lack of free space has caused the files on your system to become corrupted. You may have to resort to an Erase & Install. This of course will wipe out everything that was on the disk hence my questions about backup.

  • 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.
