Question about HP Prime G2

Ja, es ist Mac-kompatibel. Die Software (Connectivity Kit, Virtual Calculator, Firmware-Updates) ist für Windows wie Mac verfügbar unter ftp://ftp.hp.com/pub/calculators/Prime/

I don't think there is direct support for MAC from HP. But here you can find an alternative:

Since I don't have a Mac, I can't report any other experiences.
