We seem to be getting an issue when opening the same design file in a Mac vs Windows systems. In the screenshots below, you can see that viewing the designs on a Windows system that fonts are capitalised and much larger in font size. Asset alignments have also changed. The design, as it is showing for the Mac, is correct.
Have you been able to find a workaround to this? This is causing quite a bit of an issue with our team as different departments viewing the design use both Mac and Windows so there's a quite huge discrepancy and uncertainty for us.
In my case there were differences only when font size was set to 14 - I've found out that making it 13.999 looks the same on both Windows and Mac. In your case this workaround won't help. You can only try and experiment with the same font but downloaded from a different source or use a different font completely.
