What happened? Arduino 1.8.10 on MAC book pro OS Catalina

What happened? Arduino 1.8.10 is not used. There is a problem that can’t be uploaded to Arduboy !!!

I am having the same issue since upgrading to Catalina.

What should I do? I am very urgent to deal with

Right now if it’s too urgent you might have to try to find a windows computer to compile…

Oh! Too bad… i will try it , OMG

How to fix ? Use window 10 only ?

Any windows version that the Arduino IDE can run on yes.

OS X Catalina dropped 32bit support which why there are a lot of incompatibilities. Arduino is aware of this but there is no solution yet.
