When trying to install CP2104 VCP Driver, I get this error:
Result: err:(null) errResult:Unable to determine realpath for /Library/Extensions/SiLabsUSBDriver.kext - failing.
Can't create /Library/Extensions/SiLabsUSBDriver.kext.
Specifically, I am trying to install:
CP210x USB to UART Bridge VCP Drivers
Download for Macintosh OSX (v5.2.1)
MacBook Pro running macOS 10.14.7.
At first I thought this was a security error, so I checked the System Preferences - Security & Privacy panel to see if the macOS has blocked the installation. There was no indication of this.
So, what do I do now?
I tried reproducing your issue on my MacBook Pro running OS v10.14.7 and I was unable to reproduce your issue. I am able to successfully install the driver. Can you try installing the driver again?
