UPDATE: I read the release notes on V20 and apparently MacOS 11.x is not supported yet.
I recently installed the NI VISA drivers (v20) on a MacBook Pro (2019) with Big Sur.
The NiMAX application crashes, and the VISA framework fails to load with various permission errors (usually related to RAID or highpointRR).
I can't pinpoint the exact date, but last year on Catalina with V19 drivers everything worked fine.
The NiMAX program pops the main window, then quits unexpectedly with a Problem Report window.
Compiling a simple C program to link to the 'visa.framework/visa' dylib results in:
"Error Domain=KMErrorDomain Code=71 "Insufficient permissions for action: Unable to load 'com.highpoint-tech.kext.HighPointRR' in unprivileged request." UserInfo={NSLocalizedDescription=Insufficient permissions for action: Unable to load 'com.highpoint-tech.kext.HighPointRR' in unprivileged request.}
Abort trap: 6"
Advice?
