Camera zoom pivot not working on new Mac (Apple Silicon M4)

[tvignolo]

Hello,

I’ve been using MakeHuman for several years and recently switched computers. On my old MacBook Air (2015, Intel, macOS Mojave) the camera navigation worked perfectly:

Right-click + drag on the body would not only zoom, but also set the pivot to the part of the body under the cursor (for example, I could right-click on the eyes and zoom directly into them).

Right-clicking on the background would zoom “straight ahead,” as documented.

This behavior was extremely important, because it allowed me to focus on specific body parts (eyes, hands, feet, etc.) without being stuck zooming only around the torso.

Now, after moving to a new MacBook Air (2024, Apple Silicon M4, macOS Sequoia), the behavior is broken:

Zoom still works, but the pivot never changes.

No matter where I right-click on the character, the zoom always stays centered around the torso.

Rotate works, but pan is unreliable, and it’s impossible to zoom into a specific body part anymore.

I’ve tested both:

The official 1.2.0 .dmg (Intel) running under Rosetta, and

A source build with Miniforge/Conda (Python 3.12, PyQt5, PyOpenGL, NumPy 1.26) running natively on ARM.

In both cases, the result is the same: the pivot for zoom cannot be changed by clicking on the model.

Is this a known issue with Apple Silicon builds, or with newer versions of macOS (Sonoma/Sequoia)? Is there any workaround or patch to restore the original right-click focus behavior?

Thank you for any advice, and thanks for keeping MakeHuman alive — it’s an essential tool in my workflow.
