2017.2 MacOS : zooming does not work anymore (trackpad or keymap)

Hi

I can no longer zoom in the editor using two fingers on the trackpad or cmd+=. 2017.1 worked fine.

I have checked in preferences, zooming is enabled. I don't have a mouse to check if wheel zooming works - but I believe it is bound to the same broken trackpad routine.

Does anyone have a workaround ? I wear glasses and zooming is important (for me)

Thanks
