 ====== Rhino 8 Mac with Enscape Reporting "License Not Found" ======
-**Issue:** After the install of Enscape for Mac, is a Rhino license in the RA and Rhino Mac reports "**No License found.**"
+**Problem:** Install of Enscape for Mac causes Rhino for Mac to say **License Not Found** or **Initializing...** and become unresponsive.
+You can also read the forum thread  //"Troubleshooting: Data protection failed"//. //[[https://discourse.mcneel.com/t/troubleshooting-data-protection-failed/136535|Details...]]//
 {{:rhino:mac:home:license_not_found.png?300|}}
+{{:rhino:mac:home:error_finding_mac_license.png?400|}}
-This happens because Rhino was not initialized before Enscape was install and Enscape created ~/Library/Application Support/McNeel with wrong permissions.
+**Cause:** Enscape created ~/Library/Application Support/McNeel with incorrect permissions.
-The "fix" is to remove Enscape and all supporting files and then re-install and run Rhino **first** before re-installing Enscape.
-//Why?//
-We believe that this happens if you install Rhino Mac and do not license it.
-Then Install Enscape. Now open Rhino with the Enscape plugin installed.
-It is all messed up and can not get to the RA for the key.
-The lic files appears to be written on, but it may be bad or corrupt.
-===== Option 1: Manually and Complete Uninstall =====
+===== Solution 1: Apple Terminal Commands =====
+  - **Close Rhino**
+  - **Open Terminal**. //[[https://support.apple.com/guide/terminal/open-or-quit-terminal-apd5265185d-f365-44cb-8b09-71a064a42125/mac|Details...]]//
+  - **Paste the following into Terminal**, then press Enter. You'll be asked for the password you use to login to your mac. The sudo command runs with privileged permissions, and requires your password to work: <code language=bash>
+sudo chown -R $(logname) "/Users/Shared/McNeel/Rhinoceros"
+sudo chmod -R 755 "/Users/Shared/McNeel/Rhinoceros"
+sudo chown -R $(logname) "~/Library/Application\ Support/McNeel/Rhinoceros/"
+sudo chmod -R 755 "~/Library/Application\ Support/McNeel/Rhinoceros/"
+</code>
+  - **Start Rhino**
+  - **Login**
+===== Solution 2: Manually and Complete Uninstall =====
 **Simplest Solution**
-Enscape is the problem. Here's the workaround.
+  - Delete Applications:
-//You have to completely and manually remove Rhino and Enscape. //
+    - Open Finder
-This means all the **Rhino** and **Enscape** application, folders and licence keys.
+    - Click **Applications** in the sidebar.
+    - Drag **Rhino 7** to the trash
-. In File Finder go to **Applications** and delete: Enscape, Rhino 7 and/or Rhino 8
+    - Drag **Rhino 8** to the trash
+    - Drag **Enscape** to the trash
-. Now, you will need to manually delete the folders where the plugin files live.
+  - Delete Enscape Plugin:
+    - In Finder, click **Go > Go to Folder**
-. In File Finder navigate to: ~/Library/Application Support/McNeel/Rhinoceros/MacPlugIns/. Delete **Enscape** plugin folder.  //See more details on uninstalling Mac Plugins// [[https://developer.rhino3d.com/guides/rhinocommon/uninstalling-plugins-mac/|here]].
+    - Paste **~/Library/Application Support/McNeel/Rhinoceros/MacPlugIns/**
+    - Drag the **Enscape** folder to the trash
-. Now reset the Rhino licensing files by deleting the contents of these folders:
+  - Delete Rhino License Files:
-    /Users//Library/Application Support/McNeel/Rhinoceros/8.0/License Manager/Licenses
+    - In Finder, click **Go > Go to Folder**
-    /Users/Shared/McNeel/Rhinoceros/8.0/License Manager/Licenses
+    - Paste **~/Library/Application Support/McNeel/Rhinoceros**
-    And this file if you have it:
+    - Drag **8.0** to the trash
-    /Users//Library/Application Support/McNeel/Rhinoceros/8.0/ra_cache.txt
+    - In Finder, click **Go > Go to Folder**
+    - Paste /Users/Shared/McNeel/Rhinoceros/
-. And while you are in the library, double check to see if there are any Enscape folders and delete them.
+    - Drag **8.0** to the trash
+  - Delete Enscape Data Folders:
+    - In Finder, click **Go > Go to Folder**
+    - Paste **~/Library/Application Support/**
+    - Drag any Enscape-related folders to the trash
+  - Restart your Mac
+  - Reinstall Rhino. //If your Mac prompts "keep, replace ..." you did not clean up well enough. Go back to the top and try again.//
+  - Start Rhino. It should install and open like it was never installed before. And then it will get a license from the RA.
+===== Solution 3: Manually modify folder permissions =====

+     ~/Library/Application Support/McNeel/Rhinoceros
+     /Users/Shared/McNeel/Rhinoceros
-===== Option 2: Manually modify folder permissions =====
-  - Quit Rhino completely.
+  - 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
-  - Open the **Finder**, click the **Go** menu, hold the **Option** key (⌥) and select **Library**.

   - In some rare cases all the above fails, BUT after a restart the above process finally works.
+If all else fails, please get in touch with us. Standalone licensing (locking the license key to the machine) can be used as a fallback option.
-We have heard from Enscape that their latest solves the issue.
