Can't open minecraft because of launcher crash (MacOS)

Everytime I try to open minecraft I get a crash report. I have tried to delete and re-install several times, tried to update, nothing works.

I have MacOS Sierra 10.12.6. I can't find which version of minecraft I have, it doesn't correlate with the versions I can choice in the above options. It says I have version 598.

This is the report I get:
