Captivate 2017 - PC/MAC differences

Hi there, anyone know what, if any, differences exist between PC and MAC version? I use a MAC but also Windows virtually (Parallels) and (Bootcamp).

If the MAC version loses functionality then I'll go along with the PC version. Unfortunately, the Adobe page doesn't list any differences but I know from history there is usually some hit on the MAC side as Captivate was designed for PCs.
