i want to convert my
Sierra DVD to a
DMG file , so i could install it on non-mac device ( PC ).
Disk Utilities but not worked...
Is it possible to do this ? or i Have to download the source from AppStore ?
You need to make a disk image as explained in the provided link, however there is far more involved in making a Hackintosh, and it comes down to having the right hardware and understanding how to apply information about how to do it correctly.
I'd recommend watching some YouTube videos and while I haven't tried to make a Hackintosh in a few years, I'd high suggest that you should not expect it to work perfectly and it does require a decent amount of work to make it work
