Cartridge recommendations for Mac

I have a McIntosh MT-2 turntable. Had it for about 2 years, maybe 3 (the years just jumble together at this point). It came with a Sumiko Blue MC cartridge. Considering purchasing an additional cartridge or 2.  Can do MM on the Mac which I previously had on my Marentz TT-15S. Unfortunately that Clearaudio cartridge that came with it is no longer useable.  Any recommendations from those who have also had this unit. Not sure if more info needed. Everything is working just fine   Thought might be nice to have another cartridge or 2 to change out from time to time. Listen to mostly progressive rock with some occasional blues and jazz. Not much else. I know there are other sites that cater to Mac users but I only come here to read the forums everyday and appreciate what everyone has to say.
