P: Adjustment Brush Makes LR4 shut down

[FeedbackCommunityMember]

LR4 closes suddenly when I want to use the adjustment brush. I am not running other programs at the same time and I am using a brand new Mac. I did not have this problem with LR3. What can I do to fix the problem

Are you running the latest update? (Lightroom 4.3)

Hello
I'm french so if you can answer in french could be great.
I have a problem with lightroom 4.
Everytime I want to use the tool (brush or filter) the program shut down instantaly.
To be use I found a solution is to cut by myself on the photo I want to work and restart. When I finish with the photo and work with tool on an other one , the soft cut down again !!!
this is very unconvenient, I loose a lot of time !
thanks to answer me with a solution on sebastienlebegue@hotmail.com

Yes , this is the last update.
I tried to re-install, but the problem still continue.
Everytime I want tu use the tool, it shut down.
Can it be cause I upload those photo by LR3 ?

I suspect something at the system level, perhaps an older video driver.

Please try to upgrade your Mac OS to latest version, say now the latest shall be 10.7.5.
