Can't access my models, black screen or says I'm not licenced when I have a pro subscription

Hi I have the same Macbook Air M3 …

The hardware information in your forum profile is out of date. It also says you using SketchUp 2019?

@KatHart

Some don’t open at all saying I’m not licensed even though I am subscribed to Sketchup Pro.

SketchUp (desktop version) thinks you don’t have an Internet connection - Technical Problems / Known Issues - SketchUp Community

@KatHart

Other models come up with a black screen and other models crash as soon as I try to apply a texture.

You can try switching to the Classic Graphics engine via the Preferences dialog if you are running a recent release of SketchUp.

If you are running an old version of SketchUp, you might try a newer version 2024 or 2025 and take the new graphics engine for a spin.
