I have a Galaxy S4 running android version 4.2.2. and its the qualcomm variant on AT&T (i9505) and I have a macbook computer. I really would like to root and flash CyanogenMod on it because TouchWiz just makes me sick. I haven't found anything on how to do it. if someone could please give me step by step instructions, that would be amazing. I'm new to this forum and am hopeful for some friendly, helpful people. Thanks!
