I've done a lot of research about this problem, but cannot find solution. My mac randomly gives an -50 error - nothing can be written and ReportCrash is using like 200% of CPU... Restart helps, but only for a short period of time. I thought it is HDD problem, so I bought brand new SSD, but problem persists. I reinstalled OS, nothing helped. I also downgraded from OS X El Capitan to Yosemite, but nothing helps.
It totally drives me crazy, because I use my Mac for presentations for big audiences, and when it happens when I am presenting, it is horrible.
Thank you all for helping! (Sorry for any mistakes, not a native speaker :) )
