How to: Two solutions for the MacBook Pro White/Gray Logo Screen of Death. 2014 AppleCare Expires..

After turn it on again the problem started. It is the keyboard key that has the Apple logo on it a curly thing. It is the key next to the space bar. After trying multiple other ways to get my computer back, his worked for me — thanks so much!!! This worked! I tried so many things, thank you so much! Dont know if it matters, but I found it helped when it was plugged in!

I have this problem with white screen on both my iMac and Mac pro. I have tried everything! This problem must be software related! It is not possible that both my mac computers go white… It must be something corrupt with the latest updates from Apple. I got it working one time when rebooting it with my Applications install disc but that was the only time. My Mac pro starts up with white screen but I realized when I push the DVD out when I hear the starting sound the Apple logo appears and the computer is loading and It works! So after having this problem for months and tried everything possible I now understand it has to be software related!

I have also checked for Virus but nothing. Read my comment I wrote today. It might be because of disk rights. I though also it might be software related as my osx snowleopard worked without update! After update it didnt start but instead stopped on starting with white screen after apple logo. I installed osx again on the first part of the disk as I had partition split in G and G.

Dont know if that really matters but you hard drive rights must be checked and fixed with disk utility. I get the same issue as well!! It worked perfectly well this morning, then it suddenly turned itself off!! When I tried to turn it back on, that bloody white screen appeared. Please help.

When I switch it on, the ring tone chime sound is heard and then the grey apple logo appears and a black line starts in the grey bar below the logo and in few seconds proceeds towards less than half distance and stops dead.

I got so little space in my hard drive that I decided to undo partition of the disk. First I had to verify disk. That lead me into trouble as it could not be accomplished as there was some trouble. Therefore I could not finish repair either as the hd must be checked first. So I tried all kind of tricks but it went worse.

My first problem was that I had my hd in 2 parts. I tried to combine them but could not because of I had not enough space in my boot section. So I took backup.

How can I get rid of a white box on my desktop that is blocking icons behind it?

Then installed osx snowleopard to the latter part of hd. Then I got white screen after I reinstalled snow leopard. It worked in safe mode, shift pressed upon start. But none of these tips didnt work for me. What I did with disk utility was I checked disk rights and fixed them.

After that I wiped first part of hd and reinstalled snowleopard to the first and bigger part of my hd. Then I activated firewall and updated osx before anything.

It worked fine. I have a ? Version that will load to the end of the progress bar and stop. I found the utilities box. I tried all possilitities and I am on my final try by reloading a copy of OS. It is checking with Apple…. My work has been saved! Mine will not go past the white screen.

I have a late i7 and I have no clue what to do. My whole life is on this computer. I have tried all the steps listed above and still have nothing but a while screen with the apple logo and wheel of death. I have a mid iMac. So I found these instructions to hopefully fix the problem. It does not happen in the other account. I now think it comes up when I open Firefox browser which is what I use most. When I close Firefox it goes away. What in Firefox could be causing this?

First follow the instructions on this page. If there's a Firefox extension you can't remove in the Extensions manager, see below. Copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select. You won't see what you pasted because a line break is included. Press return. A folder should open with an item named "Mozilla" selected. Quit Firefox if it's running. Move the selected item to the Trash. Relaunch the browser and test. If this folder exists, you may be prompted for your administrator login password when making changes to it.

Some kinds of malware may insert code into the Firefox application itself. If the above steps don't solve the problem, quit Firefox, delete it from the Applications folder, and download a fresh copy directly from mozilla. It worked perfectly. Thank you so much Linc. You are so smart!! I appreciate your help today. Aug 24, PM. This is what was in the extension folder. There was nothing inside maybe it was because i restored Firefox in your instructions.

But I trashed the entire extension folder and no trouble. Lam H Lam H 11 1 1 bronze badge. Definitely a third party app that is listening for keyboard hits, possibly a key combination.
