Multiple displays not supported in KeyShot (Mac)

iMac (Retina 5K, 27-inch, 2020)

macOS Big Sur 11.2

3.6 GHz 10-Core Intel i9

AMD Radeon Pro 5700 XT 16 GB

iMac display resolution is 5120 x 2880

Two additional displays, one on either side of iMac:

LG HDR 4K Display - 27-inch (3840 x 2160)

LG Ultra HD Display - 27-inch (3840 x 2160)

KeyShot for Mac, version 10.1.79 [4.1.33]


I use my additional displays for all my toolbars and also to display reference images while I work. I split out all of the sub-tabs of the toolbars (Scene, Materials, Environment, Camera, Lighting, etc.) so that I can view and access any one of them at any time. I have them placed so it makes my workflow as seamless as possible. I have this layout saved using the Workspaces dropdown in the ribbon bar.

KeyShot 9 did fine at remembering the positioning of my toolbars* (and also when loading saved workspaces*), but since upgrading to KeyShot 10, it moves everything to my main iMac screen each time I start KeyShot 10. If I try loading the saved Workspace, KeyShot just reshuffles the toolbars again on the iMac screen, so every time KeyShot starts, I have to manually move 8 different toolbars around and into position.

Another related issue is when clicking a dropdown menu in a toolbar on one of the side displays, the dropdown menu itself displays at the same coordinates where it should, but on the main iMac display. In other words, if I click a dropdown menu in a toolbar that is located on the left display, the menu and its contents will display 3840 pixels to the right, in the same spot but on the main iMac display.

* With one exception (KeyShot 9): if any of the toolbars were positioned so that they were occupying the space at the top of the side displays where the macOS menu bar would normally be (the macOS menu bar does not display on my additional screens), then KeyShot would not remember the position of those toolbars. Basically, if the macOS menu bar at the top of the screen is, say, 30 pixels tall, then all the toolbars on the side displays had to be positioned 31 or more pixels down from the top of the screen, thereby avoiding the space normally used by the macOS menu bar.

Let me know if I need to clarify anything.

Hello Will,

Please perform a fresh installation using the latest full installer 10.1.80.
There are a few bug fixes for the MAC on the latest build.

Please try a fresh install using the full installer:

How to perform a fresh install:

  1. Uninstall KeyShot
  2. Make sure to delete the KeyShot  resources folder
    • note: move it to the desktop if you wish to back up your resources
      • Mac Default:
        • /Library/Application Support/KeyShot
  3. Download and Re-install KeyShot using the links below.
    For this step, you’ll need the full installer(not the update installer).
    • You can find the newest version of KeyShot here.
  4. Go through the registration wizard, enter your license information, and KeyShot should be up and running.
Please let me know how this works for you.
