I was saying in beta maybe it's more apple OS changes causing the delay.
The 2019 was that when apple banned 32 bit apps and forced to 64 bit changes that caused that massive delay ? I think the BBPlugin would be all done as the Win version still uses the 2020 code for bbw4_64.app as it don't need Utility Tracks and the the actual VST code moves over easy, pity that could not be released early or at the same time as Win with the new RT/RD at least Mac users will have all the new tracks in the BBMacPlugin.
