Raw Therapee Quits unexpectedly

Hi I have been using Raw Therapee for a couple of week on a Mac with El Capitan.
It has been working perfectly except this morning the program opens then after a couple of seconds gives me a error message that says “Raw Therapee quit unexpectedly” Please help love the program.

See “how to fix crashes on start up” and writing useful bug reports.

Hi thanks for your response it all looks very complicated and there does not seem to be a variation for Mac what about uninstall re install.

Mac is roughly the same as Linux; you should try and clear your cache first, which is step 3 in the previous instructions I linked. There are instructions for Mac on the cache page.
