Hello

 

I have a MacBookPro Early 2011. I got some pixel failures in my Finder bar:

I lost my first macbook pro thru the ATI X1600 issue, also discussed here. No interest in living thru that again.

 

do you have any idea what to do now?

 

thx for your time


MacBook Pro, Mac OS X (10.5.5)

    Yo can try with gfxCardStatus[1]: disable the dynamic switch videocard selector and force to use the integrated for instance just when you are using the battery.

    Do the black pixels (as seen on your screen shot) only show up in the Finder windows and at the same spot?

     

    Are you really running OSX 10.5.5 as your profile reads? You should have gotten Lion (or Snow Leopard, at least) when you bought your 2011 machine.

     

    If it's in Finder windows only it's likely a system glitch and a reinstall might be called for.

     

    Let us know...

    Hey thx for the reply

     

    at first, i have a up to date 10.7.4 installed, forgot to update the profile.

     

    In the meantime i was in the apple store. They suggested to send the MBP in for 1 up to 3 weeks for testing. After deciding this as a inacteptable solution i went to a Apple Authorized Dealer, explained and showed the same problem to them and got my Mainboard replaced in 30 Minutes for free because of Apple Care.

     

    The Apple Authorized Dealer also told me this problem is known, some of the ATI cards are crap. But instead of talking sensless stuff, like the people in the Apple Store, they helped me.

     

    now everything works fine.

     

    how to Fix:

    Answer: let apple switch the Mainboard

    Answer: no, but primarily, but i saw them also at the screenlock window and some other windows

    Answer: yes, using only the integrated gfx, fixes the errors
