FYI, ScubaPro's "new" software that works on the Mac is called "ScubaPro LogTRAK" and should work with UWatec's USB to IrDA dongle at least. However they have a limited number of IrDA dive computers that they support and the Aladin Sport (as mentioned by the OP) may be too old. I've never found a clear description of which ones work and which don't - but all the Galileo versions like the Luna do so you could download it and try it out and see.
You can use DiveLogDT from the Mac App Store to download IrDA based dive computers. You will need a "compatible" IrDA dongle - we supply our own drivers. We don't support setting the name and/or contact details though so it may not be worth it for you.
