This is a problem related to macOS and is due to either:
white text for blank space
- The security settings on macOS blocking NI software.
- If during the first installation of NI software, the security permission were not set correctly, then macOS will block NI Software. This setting will be saved and will not appear again, even during reinstallation of NI software.
- Or incompatibilities with an minor update to the current macOS.
1. Changing the Security Settings to Allow NI Software
- Restart your computer
- Go to System Preferences > Security & Privacy > General
- Go to System Software from Developer
- Find National Instruments. There should be a message that National Instruments was blocked from loading. Click the "Allow" button and then your NI software should work.
- The "Allow" button may not work if you are logged in remotely and may require manual log in.
2. Updating Mac OS
If changing the security settings don't work, then update macOS. It's a good idea to do a minor version update first, for example change macOS 10.13.2 High Sierra to 10.13.6
or macOS 10.15.6 Catalina to 10.15.7
. Instructions on how to update and finding update can be found in the Mac Help
pages or by searching online. Before installing a major update (for example macOS Catalina 10.15.6 to macOS Big Sur 11), check LabVIEW and macOS Compatibility
