P: Constant crashes macOS 10.13.2 high Sierra

[FeedbackCommunityMember]

Adjusting most simple things like, cropping and exposure is almost impossible...all the tools respond extremely slow. Sometimes I have to wait for more then a minute for a crop to work. It is impossible to work with it. In the last few days I have tried whatever I could think of to solve the problem. But unfortunately this is terrible. I simply can not use it. I really hope this can be fixed soon otherwise I would like to cancel my purchase.

What does the crash report say in it?

Are you syncing a lot of images currently?

Hi Parisa,
It could be an issue with your graphics card. Try these steps and let us know if it helps:

Hi Parisa,

Is this happening after upgrading to 10.13.2 or was Lr crashing on previous OS versions(10.13.1 or before) too? What camera files are you working on?

Thanks,
Venkatesh

Thank you for your comment Jeffery. Yes indeed a lot of images but the problem seems to be solved. It was a Graphic Card issue.

Hi Venkatesh, thank you for your comment. This is the first time I am working with LR. But the problem seems to be solved. It was a Graphic Card issue.

What was the graphic card issue? I am having the exact same problem in LR right now.

Go to Preferences - Performance and turn off 'Use Graphics Processor'.
