I must confess that we always had the intent of dropping the 32-bit 
slice of the engine on Mac from 9 onwards. However, the case of people 
having to rely on 32-bit only externals potentially puts a spanner in 
that - so we might have to hold over to 'the next major version'.

The reason this would be good to do is that:

   1) Beyond the (legacy) 32-bit externals problem there is no advantage 
to the 32-bit slice

   2) It means our Mac builds will halve in time (which is important for 
CI, in particular) as it only has to compile once (and not twice) per 
build

   3) It is one less 'thing to think about' when doing Mac engine work.

   4) It makes LiveCode and the apps it builds more compact.

At the very least, we'll certainly be switching the IDE to 64-bit (by 
default) and make the SB build 64-bit only (by default) in 9+.

I'll see if we can get in contact with Valentina and find out what would 
be needed to do a 64-bit version.

As a general request, can people let us know if they are relying on 
externals on Mac which are currently 32-bit only?

Warmest Regards,

Mark.
