iMac 27"retina + Parallels Windows 7

Hi Gang,

I’m running Rhino5 on Widows7 via Parallels for iMac27" Retina.

Scaling is completely wrong, some images are super small, some menus are over sized.

Please see the image attached:

Any iDeas? ))

Thanks in advance,



Parallels isn’t a supported platform:

Try partitioning using your Bootcamp Assistant utility and install your Windows 7 natively.

Thank you very much,

I can’t do that as I need to run dozens of other mac apps in the same time
That’s why it have to be parallels, not a bootcamp.

Actually it was running ideally on non retina screen.
The problem appeared only now.

All other windows programs are working just fine.
Are there any rumours about rhino + retina?
Is it actually retina friendly in case of native windows7?




Windows 7 is not good for ultra resolution monitors like the Mac Retina.
Rumors are the Windows 10 is much better at scaling the display.

That said, Parallels will continue to be unsatisfactory for OpenGL based applications like Rhino, until they get their tools cleaned up.
We are having better luck with VMWare Fusion but still not good enough to officially call it supported.

I had much of the blow up text fixed with the last bootcamp update and proper windows 10 drivers from apple on my MacBook pro. Everything is tiny but at least is consistent.

But again, that’s bootcamp and it didn’t look that bad to begin with.

Thanks a lot!

I’ll check it out.

RE: Retina (4K and 5K displays)

Rhino 5 Win 7 - issues
Rhino 5 Win 8.1 - OK (read- usable) with global Windows scaling
Rhino 5 Win 10 - equal to or better than Win 8.1
Rhino 6 Win 10 - PRESUMABLY all good

Rhino 5.1 Mac - all good on Apple Retina and third party 4-5k. I use it regularly, either Rhino Mac or Rhino 5 Win 8.1 via bootcamp .

Virtulization (Win clinet Mac host) has typically always been a bag of hurt with Rhino with any 3D complexity. Maybe one future day it might work well??? By then, perhaps GH and a plethora of plugins will exist on OS X as well…

With a System Registry key addition and copying a manifest file to the folder where 64-bit Rhino V5 lives, you can fix the small icon problem on high resolution monitors.

The details are in this new FAQ support document:

This also fixes the same issue for Grasshopper in 64-bit V5
