yeah the my hack app itself will not work but I think the terminal commands still do. like myfix /q /t /. and yes my hack's version of chameleon would also be outdated for the newer os's. also the older chameleon could not update directly from the App Store app. you had to make a new installer usb. now enoch branch might allow updating directly but I myself have not tried it. I use clover, clover will update from the app store directly.
