Hey,
So, according to documentation, recent versions of NI-VISA (21.0.0) and NI-488-2 (21.0) have been added support for Mac OS Big Sur.
I've been trying to install the versions with no success. The kernel extensions don't seem to want to load.
After installation, I have a warning about allowing new kernel extension (as usual), but clicking on allow in system preferences is prompting for a restart before it can be allowed so I clicked restart.
After reboot, there was still an entry in system preferences so I clicked allow again and again it prompted for a restart before it can be allowed.
After 2 restarts, there was no entry in system preferences so I assumed it loaded, but I was wrong. Nothing worked.
Running kextstat didn't show me any NI extensions.
I tried manually running: "sudo kextload /Library/Extensions/nipalk.kext" and got this:
Error Domain=KMErrorDomain Code=27 "Extension with identifiers com.ni.driver.nipalk not approved to load. Please approve using System Preferences." UserInfo={NSLocalizedDescription=Extension with identifiers com.ni.driver.nipalk not approved to load. Please approve using System Preferences.}
However, there is nothing in system preferences now!!
Can you please help?
