Yes, but only if you install Windows OS on the Mac with software programs such as "Boot Camp." You should ask your authorized dealer however, to perform any software upgrades unless you are very experienced with doing this type of work.

At this time no current Rotel amplifier models offer bridged mono operation.

The only Rotel power amplifier design in recent history that offered this feature was the RB-1070.

Yes, Rotel stereo receivers can power 4 ohm loudspeakers, but only if 1 pair of 4 ohm speakers is connected to the unit.  If 2 pairs of speakers are to be used with the receiver using the speakers A and B terminals, they must both be 8 ohm impedance loudspeakers.

There seems to be plenty of misunderstanding about Rotel's ability to handle these audio codecs due to the employment of HDMI 1.1 chipsets in our RSX-1058 surround receiver and RSP-1069 pre/processor. It is important to note that both Dolby and DTS recommend that the HD audio decoding be done in the HD disc player, which also provides access to other options such as additional Internet-streamed content for the movie being played. Once decoded by the player, the high resolution audio signal is output via multi-channel LPCM to HDMI input provided on the RSX-1058 and RSP-1069. Not all players support internal decoding, so you should confirm this on your particular unit. There is no loss of quality to have the decoding handled in the source player vs. decoding it in the surround receiver or processor.
