Might not have official support, but personally I've never had problems with Firefox on Mac using UI5.

I currently work on a UI5-app at SAP and even though we don't use odata, I honestly don't find the process of developing it all that unpleasant. I found it really quite easy to onboard (being productive within like 2 weeks), though it may have helped me that I didn't really have much relevant frontend experience beforehand.

Some decently cool stuff is happening behind the scenes though. I believe they're working on getting rid of the jQuery dependency, and typescript support is also coming (though still somewhat in its infancy).

I will agree that it's pretty slow though, and very heavy as frameworks go. You can do a good bit to make it quicker, but it will never win any speed awards in its current form.
