I have to thank you, mumf, because we don't see this too often from new users: first a forum discussion, then a sensible bug report with links to and fro.

Noticing that the About FreeCAD clipboard data doesn't specify what MacOSX version FC is running on. Am I wrong?

No, you are right. The FreeCAD infos I gave in the post above and the direct follow up are not shortened.

I opened a ticket issue #3538 to address the About FreeCAD missing 10.13 issue.

@chrisb - I was just messing around and I noticed this has started to work! However, I'm currently using an external monitor on my MacBook. When I move the application back to my MacBook screen it stops working. Do you think its got something to do with an Retina screen? My iMAC also has an Retina screen. Can you confirm if your MAC has a retina screen.

Can you confirm if your MAC has a retina screen.

I'm not sure. Is there a place where I can look it up? The general Mac-about tells me:

Integrierter Bildschirm (Bildschirm=monitor)
13,3-Zoll (1440 x 900)
Intel HD Graphics 5000 1536 MB

Retina displays have higher pixel density.

13,3-Zoll (1440 x 900)

That's the screen size (13,3 inch) and pixel resolution. Definitely not Retina. Just a plain ordinary display like the rest of us.

Question: issue #3537 was opened because of this thread. What's it status?

Also, in regards to Retina screens and higher pixel resolution, is there a way to compensate by making certain structures like points lines bigger/thicker in the preferences?

Ok guys, found the issue. It is related to the resolution.

I had the same issue when using an external monitor wich natively is 3860x2160 and I scaled it to 1980x1200 (otherwise it is too small).

When I run the native resolution, I can edit the drafted objects. When I use the scaled resolution, it doesn't work. So the issue lies somewhere in the handling of the resolution "densitity".

Hope it helps for debugging.

I also have a Macbook Pro which is able of even more resolution. I gonna test and see if the bug occurs there too.
