Hey RehabMan, I know that there are lots of guides about how to fix iMessage, and in the post #1 you mentioned a link for that, but as you made Hackintosh for hp envy j awesome and complete ( for me ) why don't you add the iMessage fix for this guide. it will be fantastic!
I tried to follow 2 tutorials and it didn't work , one of them made my hackintosh stop working ( i think that i did something wrong in config.plist)
But if you can provide us the best way for HP envy j , it would be awesome !
Thank you for you help!
