I'd like to start using BIAB audiophile 2018 (Windows version) on my Mac AirBook
High Sierra intel i7 ... 1.7Ghz ... 8 gig ram ... 512 gig SSD

Any suggestions as to which version of Windows 10 to use (Home or Pro) with Boot Camp?

I've had the Audiophile version since at least 2010 and I used Boot Camp / Windows to run that version on my MacPro and it ran smoother on the Mac than on a Think Pad.
I've been using the Think Pad, though for the subsequent audiophile updates, but I'm primarily a Mac user and I don't feel like getting another PC.

I'm assuming that this time around I'll be able to run the 64 bit BIAB. If memory serves, back in the old days the Boot Camp setup would only run 32 bit.

Thanks
Dave
