LW 11.6.3 won't install in Mojave, so I'm not surprised it won't run in Catalina either. The installer launches and immediately dies with an OS warning that it won't run properly.
I've tried all LW11 versions.
None work on Catalina.
Very sad. Been using LW for decades, since LW3.5.
Maybe time to move on.
I'm assuming you mean to move on to Windows.
Every version of LightWave for Windows (going back to LW4) still runs on the latest Windows 10.
If we want to ride the rollercoaster of Mac hardware and OS changes, we need to pay for all the application upgrades.
"macOS Catalina exclusively supports 64-bit applications. 32-bit applications no longer run (including all software that utilizes the Carbon API as well as QuickTime 7 applications, image, audio and video codecs). Apple has also removed all 32-bit-only apps from the Mac App Store."
Download LW 2020 trial. You will be able to work in it for 30 days or so.
Ok thanks Sensei, didn’t know this would work......:thumbsup:
