Can confirm!

I just downloaded the dev version but when I try to open Brave it crashes immediately and I get the same message as @vidacs - any ideas?

Solution:
I deleted ⁨Application Support⁩ ▸ BraveSoftware in my Library folder. Now the dev build isn’t crashing. This was mentioned in another thread.

How did you do it?

I’v tried installing Brave bEta, Brave Nightly and same thing: it doesn’t start.

Cheers

Hi, @molinafm. As @knatter mentioned, if this is the first time you’re trying to install Brave (meaning you don’t have bookmarks and such from an older Brave) deleting the BraveSoftware folder in your macOS account’s Library folder might fix this. Have a look at this related thread and see if your situation is similar (starting with @Mattches’ first reply) :
