Navigation Tools not working

Help!

I'm just started a 5 week Unity course at college, but I am unable to orbit or pan through the scenes I open. Zooming works fine.
I am on Mac, XYZ Axis is unlocked, and Perspective is on so I am not in 2D mode. Another thing I've noticed is my icons show as black compared to everyone else I've seen having white icons, not sure if that indicates anything (image attached for reference). I have tried restarting the program multiple times and also re-downloading without any changes.

I've looked all over and I can't find a solution, my professor has also been unsuccessful in helping me solve this. I'm not sure what else to do.

Anyone ever experienced this and found a solution before?

 

Im not a Mac user by any means (could be compat issue), but in your Top Right Corner, is the viewpoint of your camera (in editor mode X, Y, Z). Have you checked the settings?

"The icons black/white"., is usually due to texture assigned to the model. Check materials, textures, and assigned shader.
