Hi,
I get this error on Console.log
6/18/15 8:47:53.590 PM com.apple.xpc.launchd[1]: (cc.arduino.Arduino.293972[1543]) Service exited with abnormal code: 255
1.5 works but i need some libs from 1.6
A bunch of people have had IDE 1.6.x problems, including IDE crashes and bizarre compile errors, when they have an old 1.5.x installation. Those problems seem to be caused by out-of-date executables that the new IDE saves outside the IDE installation directory. In such cases it appears that the fix is to delete or rename the old "Arduino15" directory and re-install 1.6.x.
On Mac OS X:
/Users/username/Library/Arduino15
On Windows:
C:\Users\username\AppData\Roaming\Arduino15
Deleted the old /Users/username/Library/Arduino15 and re-installed 1.6.5 but still get the same error code.
1.0.5 (don't ask) and 1.5 still work.
