I have downloaded and run Simple-IDE_1-1-0_MacOS.pkg following the instructions here; http://learn.parallax.com/tutorials/language/propeller-c/propeller-c-set-simpleide/mac
After restart I get the message "GCC Compiler not found", then "Please select propeller load folder in the Properties dialog".
I have searched my computer for GCC and it is nowhere to be found.
Without being able to select the GCC compiler path, SimpleIDE is not usable.
Maybe not relevant but according to the instructions SimpleIDE should be installed in Users -> Your_Username -> Applications. But it does not appear there, instead it gets installed in Macintosh HD -> Applications.
