Here is a trial of support for BASICtools as an Application in OSx
Unzip this file and copy into the Applications folder, and give it a try and give us some feedback. It works on a very old Mac Mini I have here.
In Linux I had to do this command to get access to the USB serial ports. I don't know if it is needed on the Mac, I already seemed to have it, but I am the admin
gpasswd --add $USER dialout
This version does NOT have pre-processing enabled. That is a work in progress, if you want to help with that and have been compiling C programs on the Mac send me a message.
