Need some MAC assistance - Image on Userforms wonky

I have created a userform for a client and unfortunately they have recently moved to a lot Mac computers and the form I've designed behaves idiotically in the MacOS.

Specifically, the logo at the top of every form is completely out of whack, and the form itself seems to occasionally be putting itself on the right hand side of their very large screens.

On my PC, the images are perfect.

I found online a reference to MacOS needing all pictures on Userforms to be Bitmap, so I changed the pictures to bitmap. But they still look terrible.

I own no Mac products so can't resolve these two issues. Is there a way to get these images to look correctly on these many forms and get the form to stay centered and LARGER on Mac screens. It's tiny and sometimes off to the side.


There are two versions of the forms file you can look at. The regular one just has the "fixed" BMP image, but still is not displaying the correct size on the forms. V1.1

Then the second version has additional code meant to increase the size of every form by 80% when viewed on a Mac, also reportedly not working.

Any help here on these image/form placement/form size issues?

The forms are too big to post here, so I've posted them on my Excel blog.
