CERN ROOT on mac osx

[kellyM]

i am new to cern root and i use a mac osx 10.12 version. on downloading root, some of th etutorials are for mac/cocoa and i do not know how to run it asides from the terminal but when i ./the file on the terminal, i get "permission denied".

also, how do i write my code in xcode then run it in cern root?
