It is sad for me too, i’ve learned 3D rendering with it 20 years ago (using v1.2 Studio).
At some point i will be stucked with Mac OS Upgrades ( if i upgrade to Sonoma i loose my perpetual Sketchup 2019 but Perpetual 2022 can run, and ATL 2021 too…but after?)
It is a pity, i am crossing finger this is a bad joke…
