    Hi there,

    after a gamecrash, my mac pro only boots in safe mode. In normal mode my screen is totally artifacted and I have no way to navigate. What can I do about it?

    Screenshot: monitor

    - I reset NVRAM already, no effect
    - Created new user, no effect
    - ATI 3870 HD
    - OS 10.7.4 with all updates, Mac Pro (2x 2,8Ghz quad core Intel Xeon)
    - In safe mode, absolutely no problems at all. However, hardware acceleration is disabled here

    I hope this is only a software issue!

    Kind regards and thanks in advance,
