Can't open wowlet 3

Hello. I downloaded wowlet 3 a while ago but could never get it open. it always says quit unexpectedly… im on a Mac. my old coins are still visible on wowlet 1 and 2 but recent transferred coins are not there and 1 and 2 won’t sync

What kind of Mac do you have?

a new MacBook Pro. every time I try to open wowlet 3 it says quit unexpectedly
