Gave up on trying to revive old project and programs on the Mac, decided to work with micro controllers, Arduino and Raspberry Pi. Will say, once again, Apple is showing its true colors.
Using an Intel iMac 27″, 500 gb hard drive. Problem is drive is filling, and because iCloud put my home folder in the cloud, Arduino IDE doesn’t work. It appears since the libraries are really stored in the cloud and the Arduino IDE doesn’t like that. Tried to change permissions and security settings, but still no luck.. HOWEVER, everything works fine on OLD Windows 10 machines.
Sorry, this is just getting silly.
