Discussion - Drivers / FTDI VCP driver on macOS Catalina
« on: April 30, 2020, 07:51:58 PM »
Hi,
I recently installed FTDI VCP driver version 2.4.2 on my macbook. (macOS Catalina 10.15.4)
But the FTDIUSBSerialDriver.kext cannot be loaded with following error:
With some search on google, I found following blog (written in Japanese).
https://qiita.com/keyakko/items/776bf543c831f22871de
I checked my kext too, and it also shows code signing certificate has been revoked.
Interestingly, VCP driver version 2.3 can be loaded successfully.
(But it prints 'resource busy' error when open the tty device, like https://apple.stackexchange.com/questions/377174/)
Any helps with certificate error?
Thanks.
