In Egypt, not a lot changed from the time of the pharoahs, since the Macedonian aristocracy was grafted on top of the existing structures. The native people were an irrelevance, they did as they were told. There were revolts and such, which were put down ruthlessly, and business as usual for the elite continued. The elite being the upper echelons of the priesthood, along with Macedonians (first) and other Hellenes.
