Ive been wracking my brains for the last couple of hours as to why my arduino sketches wouldnt accept any libraries. When importing them via the sketch menu, the #include <lib.h> file didnt appear. I finally got round to examining the libraries directly (after a few more long winded ideas of what could be wrong) and discovered all the .h files were missing.
I did a “clean my mac” run this morning, and was wondering if that might have caused it? Has anyone come across this before? Alternatively, I also ran this script> https://discussions.apple.com/message/23529126#23529126
to uninstall some frameworks too. Could the ardunio have been sharing anything with this?
