Ok, it was working just great before the update.
Now, I close Macbook Pro lid, LED goes up to the maximum, I open lid, LED is blinking and screen is black.
It does not wake up before I press power button a few times and the after 30-40 seconds it comes back to life
Any advices?
MacBook Pro, OS X Mountain Lion (10.8.3)
Apple support articles. Since you have a Macbook Pro, I'm not sure the second one applies.
Startup Black Screen/White Text
Did you even read what I was asking? 🙂
Computer does not wake up from sleep after installing 10.8.3.
Yes, I read what you were asking and tried to supply what information I had that might help you. Sorry I failed.
Hi,
Same problem here, after 10.8.3 upgrade on MacPro not able to wake-up after sleep 😕
Was working fine with 10.8.2...
Please help
Thanks
Try booting into the Safe Mode and testing there to see if it does the same thing. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once.
you are right, disabling application at start help. now I need to identify which one is causing issues.
But there is a but, my machine wake-up but machine fan is running not as usual for aprox 1mnts and then
my screen freeze ....😟 and then I have to reboot
Any other ideas
It is usually things like anti-virus programs, MacKeeper, and other utility programs. Since applications install various files, try to find instructions on how to uninstall rather than just deleing the application itself. Some programs come with uninstallers as part of the program package. You may have to download the program again to see if there is an uninstall program.
Thanks again, but I do not have Anti-Virus nor MacKeeper, I hate such tool not really needed on Macs 😎
What is strange, and I will check this way, is that under other accounts I do not get the freeze.
Will check for any specific setup within my own account.
Thanks for your help.
It is probably a long shot, but try rebuilding the permissions on your user folder.
To do this,boot to your Recovery partition (holding down the Command and R keys while booting) and open Terminal from the Utilities menu. In Terminal, type: 'resetpassword' (without the 's) and select the admin user. You are not going to reset your password. Click on the icon for your Macs hard drive at the top. From the drop down below it select the user account which is having issues. At the bottom of the window, you'll see an area labeled Restore Home Directory Permissions and ACLs. Click the reset button there. The process takes a few minutes. When complete, restart.

I think that I found why 🙂 but do not know why it was working fine under 10.7 and 10.8.2 but not with 10.8.3
I changed my desktop picture, and then no more issue with Sleep/Wake-up ....
Very strange no 😕
Changing the desktop picture has worked for me too. I was having the same wakeup issue with OS 10.3.8 on a mid 2010 Mac Mini. The previous picture, taken from a website for such things was replaced with one from the OS desktop picture library, and the Mini wakes normally again.
