I'm thinking of moving to the Mac version of BIAB when I upgrade my computer A 27" IMac looks better to me than a new Windows machine upgrade.

I did not upgrade to BIAB 2018 because I am fed up with a 32 bit product. I started a 64 bit wishlist request in 2012. I thought I could switch to the MAC version of 2017 and my huge Realtrack and Realdrums database could be copied over from wav to aiff. Wrong - I have to buy them all again according to PG. There is no installer to choose a Win or Mac installation.

If I buy from Native Instruments, Steinberg, Ableton, Spectrasonics or lots of other companies in this music field I buy a product and an able to install 32 bit or 64 bit or Windows or Mac. And sound libraries are automatically converted to wav or aiff.

I could put a Win partition on the Mac but for only one product?
