OS X El Capitan 10.11.5 and CCID driver fix
As explained in my previous article "OS X El Capitan 10.11.5 and CCID driver still broken" the upgrade to 10.11.5 did not fix the CCID driver issue.
To fix the issue you have to download and install the "OS X El Capitan 10.11.5 Combo Update".
The file size is 1.5 GB. You can install it even if you already upgraded your system to 10.11.5.
Fixed CCID driver
Now I have:$ pwd
/usr/libexec/SmartCardServices/drivers
$ ls -lR ifd-ccid.bundle/
total 0

-rwxr-xr-x 1 root wheel 166096 5 mai 08:02 libccid.dylib.1.4.21
Note that the symbolic link libccid.dylib now points to the latest driver version.
The files libccid.dylib.1.4.14 and libccid.dylib.1.4.20 are now useless and could be removed. But because of System Integrity Protection it is not easy and I think I will not remove them.
Conclusion
The problem should now be fixed.If you installed a copy of the CCID driver in /usr/local/libexec/SmartCardServices/drivers/ as suggested by some people you may want to remove it now to avoid conflicts with the Apple provided CCID driver.
