The entire computer crashing is almost always a bad driver, or a hardware malfunction. So I would update your GPU driver, and if that doesn't work, I would then begin to run diagnostics on all of your hardware.

Computer never crashes unless you open latest version of LRC. Even the previous version worked ok.

I stick with my above statement, those are almost always the causes of computers crashing. I am not aware of other potential causes.

Yes Nick, happens to me also. Only after I updated  LRC a few weeks ago. I reported the error but they didn't respond.

Can you start LrC, but not edit anything?

If so, bring up Plug-in Manager. Look for issues, maybe deactivate all third party ones as diagnostic.

Lots of MACOS vs LrC v10 problems showing up.

I had a similar problem with LRC crashing on my iMac. Called Adobe tech support. The wait was not too long, and the tech person was excellent. Here's what he walked me through: Open Performance tab in LRC preferences. Turn off "Use Graphics Processor." LRC has its own GPU, he said, and it works fine. Also, on the same Performance page, I increased my Camera Raw Cache Settings to 15gb and purged the cache. Restarted LRC and everything has worked fiine since. My crashes were preceeded by a "low on RAM" message from my CleanMyMac software. I have 16gb of RAM on my iMac, which should be enough. But I called up my system's activity monitor's memory tab to see what open programs were using RAM. If you have a lot of programs open while you are working in LRC, that can be an issue, unless you have tons of RAM. Since I made these changes, LRC has been working flawlessly, and faster than it ever worked before. Hope this helps.
