Why would a Mac wallet not be supported any longer?? What sense does that make?
From the Hyper dev's post:
Is there a mac wallet for GP?
Unfortunately not. The HYPER Mac wallet turned out to be quite buggy and I don't have the funds to pay a full-time Mac developer for HYPER or GP.
If you know a Mac dev that would like to volunteer to build a Mac GP wallet (and perhaps even help update the HYPER Mac wallet) please let me know.
