I don't know if it has been reported yet, I can't find that. I'm in Defiance Bay and I just realize that the area of effects of the spells (for both Aloth and Durance) so not show anymore. Any idea?

Would be a good idea to post your savegame. That will help the devs determine why.

Right. Would you know where to find the save files on a mac?

Just for fun, make sure you didnt enable the Expert mode in the Options

Ouch. That's that. The game automatically unchecked the options. Don't know why. Thank you
