.d_fat doesn't work on Pd-extended (I don't remember why, feel free to
fix it), just rename it to .pd_darwin like a normal external.
hmm: apart from all the flamewars about whether it's a good idea or
not to use .d_fat and/or .pd_darwin, why do you imply that only files
with .pd_darwin are "normal" externals?
given the vanilla bible of Pd both are equals.
For the same reasons that were discussed when these extensions were
introduced. For Mac OS X, the d_fat, etc extentions cause problems
without solving any. No other Mac OS X app that I have seen uses
arch-specific file extentions. Mac OS X provides tools for managing the
different binary formats, so it should be considered harmful to invent
new ones. I think the d_fat, etc. should be deprecated and removed from Pd.
