Hi I bought an eleksmaker A3 and i tried to use it with Laserweb

Hi
I bought an eleksmaker A3 and i tried to use it with Laserweb software, my computer is a mac osx 10.10.5. I found the CH-340 / CH-341 for the compatibility with mac, the sotware reconize the machine, but disconnected it.

It said that my version of grbl is to old, i told me so to install grbl 1.1.
Do you know how it works ?

I also installed Arduino Software because i read on other post but i don’t know if i really have to. I’m a big novice for that things.

Thank you very much for your help.
