Mac OS X: Gray screen appears during startup

My mac book will not start at all

Suddenly my mac book pro will not turn off. first it started with the computer cutting off rather than going to sleeep then it started cutting off while I was using it. I became worried that there was a problem and went to back up the hard drive on an external hard drive but suddenly the computer would not start at all. before that happened i would get the gray screen with the dial and a bar underneath. Help!

See if these support articles help:

I'm trying to downgrade my icloud storage; however, my MAC book will not upgrade pass 10.6.8 and I don't have my iphone anymore. If there another way for me to do this?

I'm trying to downgrade my icloud storage; however, my MAC book will not upgrade pass 10.6.8 and I don't have my iphone anymore. If there another way for me to do this? I've tried everything I can find online and of course my coverage has expired and can't call the support team.

Hello Lara,
have you already called Apple and explained your current situation, because I don't see a way to downgrade your storage plan with a Mac only running Snow Leopard and without a iOS device running at least iOS 5.
Best regards.

My Desktop Mac Duo will not start up.

My Desktop Mac Duo will not start up. I keep getting a grey screen with the 'no entry' symbol. It can't find the srtat up disk. I cannot get it to start from the original system software CD either.

Disconnect all wired peripherals except keyboard, mouse, and monitor, whichever is applicable. Remove any aftermarket expansion cards. Check the installation DVD for dirt or scratches. Run a cleaning disc through the optical drive. Try again to boot from the DVD. If you can't, you have a hardware fault.

Replaced Optical Drive now Mac book will not boot up

I bought a second hand Mac Book Pro A1150 model. It did not have an optical drive so I bought one, installed it and now my Mac Book will not boot up. When I take the drive out the Mac Book boots up fine. I was told that the optical drive although used was tested and work when it was shipped out. I'm a little new to Macs but not new to working on computers. Is it common for a possible defective optical drive to casue a Mac Book pr to not boot up or does this sound like an issue with the optical drive cable, or possibly the logic board?

That is true. I cannot think of any way to test the Optical Drive without swapping it into a known correctly operating MBP.
A thought which probably may not be an issue. When I installed an Optical Drive in my old (2006) MBP, I remember seeing in the instruction manual an item called a grounding pad (which looked like a tiny steel brillo pad with out soap) which was missing in mine. The MBP worked and I essentially ignored it. Perhaps that may not be case with your situation.
My thoughts are that the Optical Drive is malfunctioning and the cause of your problem. Perhaps you should consider getting a new replacement from OWC. But that entails a $100 risk with no guarantees of success.
Ciao.

Mac book will not boot up,only grey screen with ? on it,Why?

Why won't my Mac book boot up,start up only grey screen with ? showing?

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.
With 10.4, 10.5 or 10.6 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, 10.8 Mountain Lion or 10.9 Mavericks, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7, 10.8 or 10.9 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.

Mac CF8 will not start with Java 1.6

I was reading a bit yesterday on problems with calling web
services on CF8 Mac using Java 1.5.x (in short, you can't use web
services). The proposed solution was to upgrade to Java 6/1.6 and
make that the default JDK on Mac OS X Leopard (10.5.4). I have Java
1.6 installed but when I make it the default JDK (I can verify this
is the correct JDK in Terminal), CF8 (8.0.1) will not start (from a
Terminal command or the CF Launcher). It says it cannot initialize
the JVM.
I understand that Java 1.6 will dramatically slow down CF8 on
a Mac but I do need to get web services going for local development
on an application. I'm thinking my 1.6 install is not good but
before going through the headaches to uninstall and install it
again, I wanted to check if anyone else has this issue and, if so,
how they got around it.
Thanks!!

I am experiencing the same issue. About 500 users are using Analyzer 7.0. When Java 1.6 is installed on their machine, the loading screen hangs, and never shows the login screen.

Power mac g5 will not start

please help me !power mac g5 a1047 will not start!

A1047 refered to all PowerMac G5 towers, as this page explains. What you need is the EMC#. That will tell you if you have a liquid cooling G5 tower, and if you do, that's another reason many fail to start because the coolent can leak.

My buddy tried to help me install windows 8 on my new mac book and all he did was put the disc in and now it will not come out and my mac book will not turn off

I cannot get the windows 8 disc out of my mac book pro

Force eject a stuck cd/dvd
First try the normal methods to remove the disc. Drag its icon to the Trash can in the Dock or select 'Eject' from the File menu.
If you are running a virtual machine, e.g. VMFusion, ensure that the CD is disconnected from the virtual machine. This will sometimes allow the CD to now show up in Mac OS X.
Shut down the computer and start up whilst holding down the mouse button. This may take some time, but keep your finger on the mouse button right up until the disc comes out or the log-in screen has appeared.
If you have Toast Titanium installed on your computer, choose EJECT DISC from the menubar.
Sometimes you can successfully use the eject disc button in iTunes even if the disc is not visible to the Finder
Open Disc utility and choose the disc you wish to eject in the left-hand pane, then click on the Eject button.
Some Macintoshes have a paperclip hole that you can insert a straightened paperclip into, manually triggering the eject mechanism.
Open Terminal and type "drutil tray eject" to eject the disc/tray, and "drutil tray close" to close the tray.
If your computer has an eject button on the keyboard, restart the computer holding down the Option key. When the startup disk selection screen appears, let go of the option key and press the keyboard's eject button.

My old version mac book airdoes not start up so i tried to reinstall lion but it says its locked. how do i unloke it with out being able to start up the system.

my old version mac book air does not start up so i tried to reinstall lion but it says its locked. how do i unlock it with out being able to start up the system.

Could be. The "lock" isn't actually looking for a password.
WARNING: This will completely erase the ENTIRE hard drive.
What you would need to do is boot to recovery > disk utility > select the MAIN drive on the left side > partition > change partition layout from CURRENT to 1 PARTITION > ensure on the right side it says Format : Mac OSX Extended (Journaled) then push APPLY.
Then if it will allow us, close the windows until you see the 4 options popup again and select "Reinstall Mac OS X" select the Mac HD and you should be good to go!
