there will be a 64 bit version - this will be WeatherCat 3, which I expect to ship in the first quarter of 2018;) [cheer]
As I understand it, 32 bit apps will not be supported in the next version of osMac. There was a thread on this but I cannot see any information as to when/if WeatherCat will be upgraded to 64 bit. Does anyone have any more information on this?
Finally, I would expect the first beta to be available January 2018.
