Time for the empty grey screen after power on
Hello all!
This is about a MacBook Core 2 Duo with a 160GB drive (7200rpm) and 2GB RAM.
I have the feeling that the time needed to start the MB has increased over month, eventhough it feels rather fast when MAC OSX is finally started. The biggest question mark is about the time the MB needs after I have switched it on till the *light grey* Apple is displayed. This takes about 30 seconds and I have the feeling that this time used to be way shorter.
How about your MBs out there? Is 30seconds a usual amount of time? Does anybody know what happens during that time and if there are any dependencies to the individual hardware config? On my MB this time remains the same and seems not to be influenced by any USB or FW devices.
Thx for your info on that!
Hi Thomas!
Are you getting a boot chime (POST)? Then sitting at a black screen? It's highly unlikely that it's taking 30 seconds to POST, but I figured I'd ask. You can try two things:
Reset PRAM- http://docs.info.apple.com/article.html?artnum=2238
Reset SMC- http://docs.info.apple.com/article.html?artnum=303319
This should resolve the issue, unless there's some potential directory damage on your HD. But it sounds like the delay is prior to the loading of the kernel, perhaps it's a power issue. Can you try to power it on without the battery in place?

After I run bootcamp and try to install WinXP.
I can't boot up from any system.Reboot and hold the option key down, choose OS X on your boot drive and set the System Preferences > Startup disk to OS X.
You can't install XP on a Mac, Apple only supports Windnows 7

Empty grey screen on startup, no Apple logo
I have an iBook G4 late 2003 running OS 10.3.9- On startup all I get is an empty grey screen, no Apple logo, no whirling gear. I immediately zapped the PRAM and reset the PMU with no change: the empty grey screen remained. I then restarted pressing the option key and I got a circular arrow for restart and an arrow pointing to the right, but no icons above them, meaning neither the Macintosh Hard Disk or the Tech Tool eDrive partition was recognized. I then tried to start the computer from the installation disk. The first time, I got the Apple logo, but that was followed by a kernel panic. I tried restarting again from the installation disk and got the Apple logo and the whirling gear, but that went on spinning ad infinitum leading nowhere. I gave up and turned it off. I suspect my iBook is ready for a funeral of some sort. If there is any way to revive it, I would be grateful to hear how from someone more expert than myself.
Hello Ira,
Does your iBook still have the original hard drive? I only ask because I had similar problems recently with the original drive on my iBook G3. After much testing and then finally replacing the hard drive corrected the problem, not that your issue is necessarily the same.
Are you able to start it up in Target Disc Mode? If so. and you have another Firewire enabled Mac to connect to, you could run Disk Utility or DiskWarrior, if you have it, on that drive to evaluate it.
If your hard drive is at fault and the Startup Manager isn't letting you select the drive, I suspect that Target mode will not work either, but give it a try.
Someone else may have a different take on this, so stay tuned.

this morning my PB G4 would not get to the password screen after power on. I have rebooted many times and very loud noises (like a HD spinning/rubbing) emits. Tried the Install disk and it cannot find the hard drive. Ran HW test and got a "Mass storage Error Code" message.
Did my HD just crash and unrecoverable? Time to replace my notebook?I believe your hard drive has failed. Hope you have a backup.

IPhone is at a grey screen after flashing for a few minutes
My iPhone is at a grey screen after flashing at the same screen for a couple of minutes.
I can turn my screen on and off, phone functions and siri both work. The screen is just grey, no error messages or anything.
This happened after I was trying to connect to a wifi hotspot and I was typing something into a field when it froze, flashed for a few minutes, and stayed on a grey screen. This has been going on for about an hour and a half.
Any help would be greatly appreciated.Hi Brialex119,
If your iPhone is flashing with a grey screen, I would suggest resetting the device and resetting the network settings. If that does not resolve the issue, then you may need to back up to iCloud and restore it.

Why does my MBP get the grey screen after backing up to external hard drive???
(firstly, i'm a complete moron on terminal, though i managed to unlock the external HD. i appreciate the simplicity of mac, i.e. a moron in many ways.)
for some bizarre reason, every time i copy files to the external HD, i end up with a lock on the external HD and the dreaded spinning grey screen when i restart the MBP. i've managed to get rid of the grey screen by reinstalling with the snow leopard DVD without formatting, but this is obviously not practical. am i doing something wrong??
the last time i did this, i dragged my "user" files. then i dragged my entire internal HD into a folder created in my external HD. i've done this with my powerbook and older OS without issues, but OS 10.5 and 10.6 don't seem to work without ending up with the spinning grey screen and a lock on the HD.
thanks in advance for your input. (and please keep it simple...)no, but it's definitely not due to a corrupt external drive. this happened with two different brands of drives. the first time with a lacie, i thought my MBP hard drive was damaged, but it was determined that a reinstall was all it needed. the same thing happened with an OWC. they both work fine. there seems to be some kind of a permission problem which gets screwed up somwhere.

ive tried loading this new software, and step 1 and 2 were successful, but after trying to restart the loading grey screen wont stop loading?
I had a similar problem, does the phone show anything on the screen, for example "update failed, connect to computer" if it does, try opening "Sony PC Companion 2.1" click start on "support zone" then click "phone/ tablet software update" a message will pop up, press repair my phone / tablet, select your phone in the list, then follow what it says, try doing this even if the phone shows nothing, you will lose everything, all data will be gone if you follow my steps

have reformatted my Imac using original discs (installed leopard (10.5)) tried to do the software update but it cant download the itunes update and when it gets to the configure update screen after restart for main update, it just gets stuck. HELP!
The configure bar gets about an 1/8 full and then just does nothing. I think its lists the update as combo update? cant remember with out checking.
I have tried to do the disk verify and repair but this has made no difference.
Please let me know what i need to do, I have reformatted the mac just to start over as was clogged with a lot of useless data, I had installed lion (10.7) from the app store previously and now cant seem to find a way to re install lion. I hope I dont need to pay for it again?If you erased your hard drive, you'll need to reinstll OS X 10.6 Snow Leopard to access the App store. You won't have to pay for OS X 10.7 Lion again. Did you try booting to the recovery partition by holding the command and r keys down? If that's still there, you can reinstall OS X 10.7 from there.
If you're looking to install the current iTunes, you need OS X 10.6.8 at a minimum.
If you're still trying to update OS X 10.5 Leopard, you can download the combo update from here. Download, use Disk Utility to repair permissions, apply the update, then repair permissions again. That will take you to OS X 10.5.8. -

Is there an icon for face time on the iphone4s home screen? I remember I saw it before but not any more. I still have the FaceTime app,but would like to find the icon on the home screen again. Anyone can help?
Check all of your folders to see if FaceTime is in any of them.
If not, check your restrictions (Settings>General>Restrictions) and if restrictions are on, and you know the passcode, then FaceTime might be turned off. Turn ON to veiw icon on home screen.
Let me know if this does/doesnt work. -
Hello my MBP 15" stops at grey screen after apple logo disappears
hello, my MBP 15" stops at grey screen after apple logo disappears, what can i do about this? ive tried booting into safe mode but screen turns blue with black lines also tried resetting NVRAM and PVRAM but still stops at grey screen, also tried using applejack, it shows no problems at all, says my disk volume is ok but the screen still stops at grey during start up, havent tried the installation disk thing because i dont have my installation disk with me
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.”
b. 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.
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
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 either of the techniques in Steps 1b and 1c 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 10. 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
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 10
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 11
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 12
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. -
How do I get past the empty blue screen?
I keep getting the empty blue screen. I have tried starting up in Safe Mode only to wind up with the same blue screen. Tried starting up with iMac install disc only to wind up with the same blue screen. Additionally it has decided to keep the disc. The problem started with a poweer outage and an apparently bad battery in the power back up. Although I have the Apple Care Protectiion Plan, i have not been able to get in touch with them. Any assistance would be greatly appreciated. I have wasted the last four hours only to wind up "blue". At the moment the iMac is in the grey apple screen with the gear rotating, the install disc 1 is still in the drive. it has been in the screen for the past 20+ minutes..HELP

Mavericks grey screen AFTER login on MBP?
Hi there,
I've bought a new MBP 13" Retina w. Mavericks installed (december 2013).
It ran like a dream, but when I tried to login via the guest account (for the guest time), it seemed to not go anywhere - freezing (w. the spinner still circling).
I held down the powerbutton until it powered up.
After this, i get to the login screen (w. mine + guest login), but nomatter if I log in as guest or my normal account i end up w. a blank grey screen after.
I've rebooted many times and tried resetting the PRAM, but with no improvement (as the "start process of the boot" is fine, until after the login).
There are no USB's or external things connected.
Any ideas? I did of course not have full backup :-((
Thank you in advance!!Try booting into Safe mode (hold down shift while you start up). This takes five minutes to do a Dsik Utility (Repair Disk) then shows a special login screen and demands your username and password.
You can poke around and make sure things look ok. A few things are slower in safe mode, as only the most essential Drivers are loaded.
When you re-boot into regular mode, the start up may take a little longer as it rebuilds a few more things. Let us knoiw if that helps of not. -
Stuck at grey screen after reboot
I seem to be stuck at the grey screen after a reboot of my server. Here are the symptoms and I'm wondering if anyone has experienced them before or has some idea of where to look:
1) Over the last couple of weeks, I've noticed the entire system freezing up for 10-20 seconds. The spinning pinwheel pops up and when my office is really quite, it sounds like either a fan is starting on the system or a hard drive is spinning up. Note that I've turned off all 'spin drives down when possible' in energy savings.
2) After the 10-20 seconds, a bunch of disk activity occurs and everything goes back to normal.
I've tried repairing permissions, checking for errors with the drive, etc. I've got two drives striped in Raid 0 (yes, the system is backed up--so I'm not worried about loosing data).
After a recent software update, I had to reboot it, and that's where it got stuck. Could be something there for some time, but my server usually runs for months at a time, unless an update requires a reboot.
Thanks for any help or suggestions!Could you be more specific about what disks you used to boot with and exactly what programs you ran...
I cannot seem to get it to boot from the "Admin Tools" disk using the "D" key.
Also, when booting from the "Mac OS X Server" disk I can access Disk Utility, but do not see Raid Utility anywhwere. -
