Will not boot past grey screen
My MacBook Pro boot to the Apple Logo with progress meter just fine. After a normal space of time it continues as though it is going to boot normally but instead of going to the blue screen or blue screen with the cursor arrow it goes to what I would call a white screen and just stays there without booting any farther.
I have changed the Ram, I have reset the PRAM, I have changed the HDD, but it hasn't helped. It will boot in the Safe Mode without a glitch but when I try to reboot in the Normal Mode it returns to the white screen after displaying the Apple Logo and progress monitor.
I do not have the original install discs for this computer and even if I did have I wouldn't know how to best use them.
Can anyone help me?
If the system will boot into Safe Mode functionally, it's possible that the damage is limited to your user account. Some user resource may be damaged, or you may have installed some software recently that's loading at startup and screwing something up.
One diagnostic trick is to log into safe mode, then create a new user account. Go into System Preferences>Acc
You say you replaced the hard drive. Did you transfer all the data from the old hard drive to the replacement? If so, you probably copied the problem data from the old drive, too.
Once you get a usable external drive with 10.4.6 through 10.6.8 (either a bootable hard drive, or any bootable system install disc - retail or OEM, whether it's intended for your computer or not), boot from that drive. When you're fully booted to the finder or the system installer:
- locate Disk Utility (in HD>Applications
>Utilities on a hard drive, in the Utilities menu on an install disk)
- select the icon for your suspect hard drive in the left-hand pane
- click the "First Aid" tab
- click "Repair Disk"
When that operation has finished, look to see what got "fixed". If there's a long list, run it a second time; you should get fewer things repaired.
Once you've finished with Repair Disk, quit Disk Utility and reboot from your hard drive. Ideally, you should then be able to boot to the finder.
I have the same problem on my A1150 Mac Book Pro with a grey screen at boot up after the apple logo, even after a SMC reset, and PRAM reset, but I can boot using a safe boot, although the mouse has a small checkered box. I ran disk utility in Safe boot from another disk partition, and found no problems with bad clocks on the hard disk, or disk permissions issue's. This Computer was given to me, the Apple consultant told me that it would only boot into a black screen before even when connected to an external monitor. I googled the black screen issue, and found a you tube video on "How to Bake My Mac". I removed the logic board, which has an embedded ATI 1600 GPU. I wrapped it in foil, exposing just the GPU chip, and placed it in the oven to re-flow the solder , after it cooled down I put the Mac Book Pro back together, and it's been working for several months with out issue, until this past week. Could this be an issue with the PRAM battery causing the grey screen, or possibly the GPU needs to be re-balled?
Since it's a 2006 Intel Core Duo, and not a Core2 Duo CPU, I am just not sure that it is worth putting another $150.00 - $300.00 into it?
