Hi Juan,
You know I have been waiting for this announcement. ;-) So I could not wait to try.
I am running macOS Big Sur 11.2.3.
I used Cuis5.0-4526.image. The other images don’t start.
I set ComputerModernSans as the system font. That’s a TrueType font, right?
When I evaluate M3Exp01Morph new openInWorld Cuis asks if I want to install and activate VectorGraphics support.
I answer yes. A morph appears near the top left of the screen. When I try moving it Cuis freezes and CuisDebug.log files appear, see below.
I tried the same with all packages loaded with the same result.
Any idea?
Cheers,
Bernhard
