Hi. I got this problem while ago, when I start it up and log in on my admin account I have this gray screen flashing on my desktop and my dock is missing. But I can still access almost everything but what the **** gray screen flashing is annoying and I dont know where my dock goes. Anyone knows what is happening on my laptop? Thanks.
MacBook Pro
Pleas advise the EXACT model of MBP you have and the OSX.
Ciao.
I'm having the same problem on Macbook pro 15" on OSX Mavericks version 10.9.5
Sorry just checked it's actually a Macbook pro 13" mid 2012 on OSX Mavericks version 10.9.5
Boot into the recovery partition and select Disk Utility from the 4 option menu.
Run Disk Utility>First Aid, Verify and Repair.
You also can try a safe boot:

If that eliminates the problem, then there is probably a third party item causing the problem. You will have to track that down.
Ciao.
Sounds like you have assistive services activated (There is a three finger short cut you may have in accidentally pressed)
Check Accessiblity in system preferences
under display make sure Grayscale is not checked
under audio make sure flash display is not checked
As for the dock make sure you haven't got it hidden by placing mouse pointer to each of the left/right and bottom screen edges
If not go to the following folder in finder.
Open Finder window and mouse and click to the Go menu to view list of actions. On your key board press the Option (alt) key and you see a extra action location added after Home - this is the hidden library folder in your Home directory
This contains all sorts of personal setting preferences
Now continue to hold down the option key and mouse click on the Library item to open the contents in the main finder window.
Within the window locate and open the folder - Preferences
Locate this file from within
com.apple.dock.plist
move this to the trash
Shut and restart your Mac
The default dock setting will appear - Empty trash
Tell us how it goes.
Tried both the Accessibility settings and deleting the preferences file neither of which worked.
I've done a verify and repair in recovery mode and it still hasn't fixed the problem.
*Update* One I first startup my macbook it does the flashing thing and there's no dock but after a while it came back with the default dock and stopped flashing.
It seems to be fixed now cos it loaded ok the last couple of times I've used my macbook. Thanks for the help. 🙂
