In this case, you may delete the driver installation entries manually using the following procedure:
run the terminal application (which you can find by searching in Spotlight)
After opening the application in the window that appears, make a copy and paste of the command
cd /usr/local/libexec/SmartCardServices/drivers (press enter)
Then insert the following command ls (press enter)
note: this command checks the list of files present in the path where it is currently located
You’ll find lines like that:
drwxr-xr-x 3 root Jul 4 2016 ifd-b4iccid.bundle - è il nome del file -
lrwxr-xr-x 1 root Jan 4 23:37 ifd-ccid.bundle -> /Library/bit4id/ccid/ifd-ccid.bundle - è il nome del file -
You must delete all files in this path. To delete, use the following command: sudo rm -rf followed by the file name to be deleted.
example: sudo rm -rf ifd-ccid.bundle (press enter)
Delete other entries if present using the same command followed by the file name to be deleted.
Once there are no more files to delete install the Bit4id driver: Driver 2.5 Mac OS
After installing the package and restarting the system, try the smartcard reader again.
