AX- That would make sense. 6.1.13.1 Mac was not working for brand new installs but worked OK for anyone that had any older version of B6 installed. Looks like they left out something in the 6.1.13.1 build so instead of fixing the missing components they just rolled back to an older build. Too bad since there were some Mac bug fixes in 6.1.13.1. Electro - see my comment to Su in the post before yours.
