Should petGRO source new MAC's or PC's?

I believe that petGRO should source new PC desktop computers for the firm. A PC is easier to use and has useful programs, like excel, that the company could put to good use. Not all programs translate well from PC's to MAC's, and they are often not very compatible even if the program exists for both computer types. Especially since petGRO has gone with the BYOD, a desktop computer that is highly compatible with all models of phones would be smart, and the PC is the best for that. The MAC can be quite difficult to navigate and older employees could get frustrated, and that would not be good for the firm. A PC is best for workplace activities, whereas a MAC is geared towards leisure work and activities. So for the petGRO, they need a computer geared towards workplace actives, so the PC is perfect for that. In the end, petGRO should choose to adopt PC desktop computers for their firm.
