fail to open MrView on MacOS High Sierra 10.13.6

I am a rookie user. I just installed Matrix3 on my MBP. However, I got the error message “MRView cannot be opened because of a problem”. The message suggested to check with the developer to make sure MRView works with this version. Can anyone help?


Are you sure that’s the full error message? Can you run mrview -debug in a terminal and copy/paste the full output produced?

Thanks and all the best!
