I¡¯m trying to help you make it run on your Mac and for this have some questions, if you don¡¯t mind.
So you got a hex file or a ino file from Gary and you had to use Windows for uploading or compiling and uploading?
Did you use the Arduino IDE on Windows for this or used the ArduinoBuilder?
It¡¯s ?somewhat confusing.
i don¡¯t think it¡¯s a problem with your Mac if compilation fails. A lot of people, including me use Macs for Arduino development without problems.?
First you need to have a proper C ( ino) file, which according to the errors you posted is not the case. You are trying to compile a file with ?html content, so as already mentioned before obviously something went wrong with your download. The same file compiled under Windows would als have thrown errors.
Did you use the downloaded ?zip file from GitHub or used another method to fetch the files?
