Problem: Install of Enscape for Mac causes Rhino for Mac to say License Not Found or Initializing… and become unresponsive.

You might see “Troubleshooting: Data protection failed”. Details...

Cause: Enscape created ~/Library/Application Support/McNeel with incorrect permissions.

Simplest Solution

Enscape is the problem. Here's the workaround. You have to completely and manually remove Rhino and Enscape.  This means all the Rhino and Enscape application, folders and licence keys.

1. In File Finder go to Applications and delete: Enscape, Rhino 7 and/or Rhino 8
2. Now, you will need to manually delete the folders where the plugin files live.
3. In File Finder navigate to: ~/Library/Application Support/McNeel/Rhinoceros/MacPlugIns/. Delete Enscape plugin folder. See more details on uninstalling Mac Plugins here.
4. Now reset the Rhino licensing files by deleting the contents of these folders:
   1. /Users/you/Library/Application Support/McNeel/Rhinoceros/8.0/License Manager/Licenses
   2. /Users/Shared/McNeel/Rhinoceros/8.0/License Manager/Licenses
   3. And this file if you have it:
   4. /Users/you/Library/Application Support/McNeel/Rhinoceros/8.0/ra_cache.txt

1. And while you are in the library, double check to see if there are any Enscape folders and delete them.
2. Restart your Mac
3. Reinstall Rhino. If your Mac prompts “keep, replace …” you did not clean up well enough. Go back to the top and try again.
4. Start Rhino. It should install and open like it was never installed before. And then it will get a license from the RA.

1. Quit Rhino completely.
2. Open the Finder, click the Go menu, hold the Option key (⌥) and select Library.
3. Open Application Support and look for the McNeel folder.
4. Right-click it and select Get Info.
5. Go to the Sharing & Permissions section and click the padlock to enable editing.
6. Change the permissions to Read & Write for all the entries.
7. Click on the options menu at the bottom left of the window (the circle with the three dots) next to the + & - symbols.
8. Select the option Apply to enclosed items…
9. Close this menu and start Rhino again.

or

Please check if you have read & write privileges on these license folders. To do this, right click a folder > choose Get Info > and check the permissions at the bottom of the window that pops up. Make all of them Read + Write.

   /Users//Library/Application Support/McNeel/Rhinoceros
   /Users/Shared/McNeel/Rhinoceros

1. For the User > Library folders, make sure you are in the one from the Go menu in the Finder app when the Option key is held.
2. Start Rhino 8 after making sure you can write to these folders. You should see a Welcome screen to enter your email. If that still doesn't work, try deleting all McNeel folders from both ‘/Application Support’ and ‘/Shared’ before starting Rhino 8

Advanced Skills Required

1. Quit Rhino 8.
2. Restart your Mac.
3. Ensure Rhino 8 is not running.
4. Launch Terminal.
5. Remove the folders that Enscape created.
   1. If Rhino 7 is installed and working and you only want to fix Rhino 8, paste into terminal and press Enter:
   2. rm -rf ~/Library/Application\ Support/McNeel/Rhinoceros/8.0
   3. Or, paste rm -rf ~/Library/Application\ Support/McNeel and press Enter.
6. Start Rhino 8
7. With Rhino successfully starting, now you can reinstall Enscape
8. if you get “permissions denied” as a return when you run the steps above, add the prefix sudo then a space, then the command string above. This will call the admin credentials dialog box allowing you to enter admin credentials. Enter admin credentials and the command string should complete successfully.
9. If all the above fails, you can browse directly to the folder in the finder and delete the folder manually by dragging it into the trash. (confirm with admin credentials)
10. In some rare cases all the above fails, BUT after a restart the above process finally works.

Run these command in your Terminal Application

sudo mkdir -p ~/.config/.mono/keypairs
sudo chmod -R 700 ~/.config/.mono/keypairs

We have heard from Enscape that their latest solves the issue.
