MS project on MAC

just starred a new job and boss got me a high end PC because he wants me to use MS project. I HATE PCs with a passion and this thing is killing me. I def dont want to do the partition thing and run both MAC and Windows on a MAC. WHY doesnt project work on MACs?! I want to switch to MAC but need to know of any good alternatives to MS project? i wont exactly be a power user - just need to make simple schedules.
