MacBook Air, purchased 2011. Stuck on grey apple screen. Help!
MacBook Air purchased in 2011, never had any trouble previously. Grey Screen stuck in thinking mode, will not accept any commands. Have let battery drain and re charged but no difference. Any thoughts? Thanks.
Being stuck at the grey screen generally means there's something wrong involving reading something from or writing something to the hard drive. Letting the battery die may be something that is sometimes useful for a phone or iPod, but never for a computer.
Step 1: try restarting in Safe Mode. Reboot and when you hear the chime and/or the LCD backlight comes on press and hold the shift key until you see the Apple icon. The bootup will take longer than normal because the hard drive is being examined and repaired. If this works you'll get to the desktop but Safe Mode only loads a minimal number of drivers so some things won't work. Reboot normally and see if you can get to the desktop now. If Step 1 failed or if after rebooting you returned to the gray screen try step 2.
Step 2: try restarting in Recovery Mode. Reboot and when you hear the chime and/or the LCD backlight comes on press and hold the command and R keys. You should boot into a utility mode where you can a) check the hard drive directory and repair it if need be and b) download and reinstall the operating system and that's what you should try doing.
If step 2 fails reboot holding option, command and R. This is Internet Recovery mode which is similar to Recovery mode except the drive will probably need to be formatted or partitioned before the OS can be reinstalled. This will erase all your data.
And if this fails call AppleCare or make an appointment at the Apple store.

MacBook Pro (late 2011) stuck at white Apple screen.
Hi all. My MacBook Pro 13 inch (late 2011) is giving me the same problem over and over again.
Few months ago, I had sent it to Apple for repair due to faulty HDD. Now the same problem happened again. The MacBook will stuck at the white Apple screen with the circle turning when attempting to switch on.
However, Apple had just replace a new HDD and why it's still happening again?
Can anybody here please assist to advice me what is making my Mac unable to start up, stuck at the white Apple screen, even after replacing a new HDD?
Thank you!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 boot failure is to secure your 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 your 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 hold the backup data.
a. Boot into 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.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot 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.
c. 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
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot 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, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your 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 reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. -
After Update to 10.5.8, stuck on Grey Apple screen with turning gear...
After Update to 10.5.8, stuck on Grey Apple screen with turning gear... and it just stays there...
Apparently I can't safe mode it
Started it in verbose mode and it say disk02 i/o error
Then I restarted it in single user mode, did a sbin/fsck -fy and it says that:
*files have been modified*
*REBOOT NOW*
I reboot and still the same problem.
When I put in the install disk it says *cannot install in this drive* (was thinking about archive and reinstall, but I suppose not ) then when I repair and verify, it says All seems OK
Yikes. Yikes!
Please help.
Message was edited for additional clarity by: BrzrKrkWell, I brought to the Apple Store's genius bar. Can't say enough about the experience... they archived and reinstalled... tried everything else and like sometimes happens, transfer of data can become corrupt in a spot that just makes things go haywire. So the Archive and Reinstall worked like a charm.
Moreover, they replaced my Macbook's top board casing (don't know what else to call it..) (where you rest your hands to type) it was cracked and stuff... not under warranty, but they will replace it free due to design ... I am impressed and pleased... *and me? I am a cynical critic* still, they made the experience as painless and certainly pleasant as possible.
For all who are having problems, I urge you to not damage the wall any further with continuous headbanging: make an appointment and definitely visit the Genius Bar. Your head will thank you -
New iMac is stuck on grey apple screen after restart from Migration Assistant
New iMac is stuck on grey apple screen after startup. It is a 3.4GHz Quad-core Intel Core i5 running OS 10.9.4. The problem occurred after a migration from my older 2009 iMac which is running Snow Leopard 10.6.6. When the restart occurred from Migration Assistant, the new computer will not boot up to the login screen. Disk utility did not solve problem. Followed instructions for a soft reinstall of Mavericks but that also did not solve problem. Any suggestions?
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 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. -

MacBook stuck at grey apple screen with spinning logo
I have a 2010 White MacBook that is stuck at the grey apple screen with a spinning logo. This seems to have happened after I installed the newest version of iTunes. The system slowed down a lot and when I ran the system monitor It said all of the memory was being used up. I had to force shut down by holding the power key. Upon reboot, I got the grey apple logo screen, a spinning wheel, and a progress bar. The progress bar gets about a quarter of the way and disappears. The spinning wheel remains. Initially, I let it run for awhile. Nothing different happened. I took off the Mac jack adaptor, and replaced the battery. Nothing happened. I kept trying to start it up and one time it worked. I backed up my files to two external hds via time machine.
Upon the next boot, i have been stuck at the grey apple logo screen, spinning wheel, and progress bar. Each time the progress bar remains and then disappears after going about a quarter of the way. I have tried cmd-D, cmd-s,cmd-opt-p-r, cmd-v but I don't think any of those work (I don't know of i'm doing them right) . It just stays on the grey apple logo screen. I tried using the option button at the startup and it goes to a lock screen. I typed in the administrator name. That didn't work. I tried the apple password. That didn't work. I tried every password that I know. None work.
What can I do to fix this?
Thank you.See if this Apple note will help. When it gets to Disk Utility, boot holding the command and r keys down so you get into recovery mode, and run Disk Utility from there. Assume you have OS X 10.7 or later. If you're still on OS X 10.6, then follow directions to boot off the OS X DVD sent with your system or a retail OS X 10.6 DVD.

Reinstall OS X:
Reinstall Snow Leopard without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.
OR:

Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer. -
My Macbook Pro will not load past grey Apple screen...
Last night my Macbook Pro froze so I closed it and went to bed. Today when I opened it, it was still frozen, so I held down the power button and rebooted it. It got as far as the grey Apple screen with the spinning wheel and will not load any further than that. I've rebooted a couple times since and it continues to do the same thing, stays on the grey screen forever.
I searched this problem on the Apple Support Communitites and none of suggestions (holding Shift after the startup tone, holding Command+R) have worked so far. Is there any way to fix this problem without losing my data or having to pay to talk to Apple Support? PLEASE HELP! :(Zzoozu wrote:

Then we can't help you as we need you to be able to help yourself and the instructions are complicated and long to paste here over and over again for the same proceedure.
Hire the services of a local Mac computer repair before you delete your data by accident.
You can jump down and do #8, that might clear the issue right away, but some programs are not going to work and require updating or reinstalling again.

Mac mini stuck at grey apple screen
I was in the process of streaming some music through itunes from a samba share when my mini locked up hard and I was forced to do a hard reboot, upon startup now the mini is always stuck at the grey apple screen.
I hear no startup sounds other then the disk firing up (no welcoming chime) and from what I've tried, the system seems unresponsive to startup options (ie. holding shift, command v etc.).
I tried the obvious and disconnected everything and tried to restart but had no luck. Has anyone else been able to revive a bricked (bricked from what?? ) mini?Hi All, I am sharing the same problem.
I have a Intel Mini, last night woke it up and clicked on itunes, the arrow swithced to the pinwheel.
Clicked on itunes and it said the "application was not responding" tried to force quit and nothing happened except for the pin wheel, I was able to get the computer to restart, well that process froze up too.
I did a hard reboot and the gray screen came on with no dark grey apple. Shut it down from behind the mini, went on with other thing, came back turned it on from behind again, this time I got the grey apple and grey pin wheel but it didnt go any further.
I checked out this post, restarted the computer while holding down the "C" key with the leapord disk.
Went in to disk utility clicked repair disk, message said the disk couldnt be verified/repaired. I then went to the sartup menu and shut down.
Any idea someone could tell me what to do next? -
Screen stuck on grey apple screen with a loading sign
I thought i had lost my charger and i wasnt willing to fork out the money to buy one for awhile. During a recent move i found it. I charged it up but when i got to my login screen i kept trying to type my password and it wouldnt except it. After looking online i found several posts about click buttons i dont remember what exactly i clicked but it was along the lines of " option and the R key" Another screen popped up and it had several options one of which was to try to do a back up/ restore it through timemachine. I treid that and it wasnt working. I went back to the screen and saw an option that said install the lion thing. i tried that and it didnt work. I was frustrated so i decided it would be best to just shut down my computer and try again when i was less riled up. Well now it has been stuck on the grey apple screen with a loading sign under it for atleast a day now if not longer. I have no idea what to do. I'm not sure if i have apple care or not. Oh and not really sure what operating system i was using.

Stuck on grey Apple screen, how can I erase and restore back to original?
I've been trying to restore my imac G4 flat panel back to its factory settings, as I have recently backed up my necessary files on an external hard drive. It came with Panther and I upgraded to Tiger, but now I don't have any of the disks. I don't care if it restores back to Panther, I just want to erase and restore it. I tried to download and mount the restore disc and do it from there, but now its stuck on the grey apple screen. Any help would be appreciated.
Hi Jared, and a warm welcome to the forums!

Stuck on grey apple screen at boot up
Mac Mini Intel Core 2 Duo 1.83GHz, no hardware changes since purhcased, a year and 4 months ago. OS 10.5.6. Today it decided to croak. When I tried to restart, it got stuck on the grey apple screen. I did the following:
• Reset PRAM
• Reset SMU (I even tried the PMU reset, which results in the fan spinning at max speed)
• Tried booting up from DVD
• Tried booting up from external firewire drive
• Set it in target mode and verified via firewire that the internal drive is working fine (I checked it with Disk Utility with no errors found and even booted up from it). In this mode even the DVD in the Mini's drive showed up on the other computer's desktop.
• Reseated the RAM
• Replaced the RAM
Is it the motherboard? In which case, this will be an excellent door stopper... Thanks for any help.I'm concerned, with you creating and using all the discs. Only the right one is supposed to be used, refer to http://support.apple.com/kb/HT1237
Boot ROM Version: MM11.0055.B08
SMC Version (system): 1.3f4
Based on your computer description, the Correct RESTORE CD appears to be V1.3 or 1.7. the applicability is at the bottom of the page.
http://support.apple.com/downloads/FirmwareRestoration_CD_17
Follow instructions
http://support.apple.com/kb/HT2213
You might want to try 1.7 again. If you don't get a complete code, your computer could already be at the correct firmware status. I'm am not familiar with any other reasons for why it would provide an incomplete installation. My guess is the software checks the Boot Rom and SMC version and stops, if it sees the right version. My computer reacted similarly when I upgraded recently. Now that is working, I can see the Boot Rom and SMC version are correct. At the time I never got to a choice of where to startup. refer to previous posts.
Which means this firmware update doesn't solve the problem.
So back to basics:
After completing the Firmware update, did you try that trick with the remote to chose your startup device? Does it let you boot from CD? or HD?
Selecting start-up CD = grey screen
Selecting hard disc = greay screen
You reseated the RAM, Did you perform the hardware test? http://support.apple.com/kb/HT2341
Verify the RAM is available.
I know that my disk utilities CD said my HD was good, but when I ran it with my new Snow Leopard utility it said there was a problem that required reformatting. If you were considering upgrading, I would do it now.
My solution was the remote trick, but that doesn't appear to be working for you.

Screen Stuck on Grey Apple Screen
Hello, I have been trying to power on my mac since this morning and it's stuck on the grey apple screen at boot-up. I have powered it off/on and it's still doing it. I also powered it off for 8hrs. and it won't come on tonight again. Can anyone please help. Thanks.
I like the free demo of SuperDuper to make clones. It's free, Tiger ready and is easy to use. If you buy the full version you can do incremental backups.
You should use Disk Utility to do a Disk Repair, as shown in this link, booted up on your install disk, before you make a clone of it.
I then partition my external disk, in Disk Utility, with a partition that is the same size , actually a tad bigger, as my system disk. I then use SuperDuper to clone my system disk over to that partition.
With a clone on an external FireWire drive (USB drives are not bootable on Macs) you can bootup on it to do your repairs or just run your Mac anytime you have trouble with your main drive. Be careful, there are a few external FireWire drives out there that are not bootable on Macs. Check the drive's manual to be sure.
Cheers! DALE -
MacBook Pro: Tiger wont boot past grey apple screen w/ spinning gear, HELP!
Hey everybody,
I have a 1.83 Ghz MBP with 512 mb of RAM (lame I know). The other day someone was using my computer to burn a CD on iTunes when all of my programs began failing. On instinct I rebooted my computer to solve the problem. Alas, now I cant boot past the grey apple screen, and the gear is spinning away. Saddest part of the story is that I had time set aside to back up my computer the day after this happened . Anyway what is the best thing to do from here? I haven't made any moves to fix it yet really, so what is the best thing that I can do to try and get my files back?
Thank you,
Sam A.Hi, I posted to you in yoour other thread.
I very much doubt Disk Utility or fsck will fix an +Invalid Node Structure+ error. That's a pretty serious error and DU is just not robust enough of a utility to repair it.
If Disk Utility can't fix it, you'll need a more robust utility for the repair. I would recommend DiskWarrior. It is the best at directory repairs. It rebuilds then actually replaces your old directory. I feel every Mac owner should have a copy. Make sure you get the disk so you can boot up on it to run repairs. You can also install it on another drive and run it from there to repair this one. DW works faster that way.
I use DW once a month to try and catch errors in my system from getting too far out of hand.
If you have a good backup, hopefully a clone of your system before you had issues, an Erase and Install will also rid you of this issue. But, beware! You will lose everything on the drive with this procedure. Let us know if you need help with that!
Cheers! DALE
p.s. If the +Invalid Node Structure+ is real bad, there's a risk even the mighty DiskWarrior will not be able to help. Normally it will come thru; it's only in the severe cases it won't be able to do it. If you don't have a backup, and need the data bad, it's worth the try! -
Yosemite Stuck at Black Apple Screen - HELP Please
Tried to install Yosemite on my Macbook Retina Pro stuck at Black Apple Screen Progress bar is about a third done. Beach Ball is spinning been more than five hours. Tried a reboot, zapping Pram etc. still no go. Should I reinstall old system and if so should I use my Time Machine back up or do a fresh install of Mavericks?
**** everything was working so nicely before I tried the Yosemite update.Hi,
Do you mean that you're unable to logon to Windows no matter via normal start or safe mode, and startup repair doesn't work with the disk?
For this error "gets stuck at 'Loaded: \Windows\system32\DRIVERS\avgidsha.sys' every time", hope this link can help you

As I look into using material determination, it looks to me as though the effective (validity) dates are at the table header level, not at the individual condition record level. Is this true? Is there any way to allow the validity dates at the cond
