MAC - Hey Gang trying to create a Save file, what am I doing wrong here? FileNotFoundException: Could not find file "/Users/zak/Library/Application Support/M2H/PhotonUnity/gameInfo.dat"

Trying to create and load a save game file for my game however I'm running into an error: FileNotFoundException: Could not find file "/Users/zak/Library/Application Support/M2H/PhotonUnity/gameInfo.dat"

Also will a fix also work on windows builds?
