Since Mac OS X Yosemite (10.10) the pcscd command is no more present. See "OS X Yosemite and smart cards status" for more details.
The problem is that I used this command to get some debug log from my CCID smart card driver. See "pcscd debug output on Mac OS X". Unfortunately this technique is no more available.
/System/Library/CryptoTokenKit/com.apple.ifdreader.slotd/Contents/MacOS/com.apple.ifdreader father process is process 1. Process 1 is launchd "System wide and per-user daemon/agent manager".
If I start the command from a Terminal I get no error message, the command does not return but in the/var/log/system.log file I find:
So I think some parameters and/or context is missing.
The process is started by launchd. The configuration file is/System/Library/LaunchDaemons/com.apple.ifdreader.plist . It contains:
com.apple.ifdreader process.
First you need to stop the process. You can use:
Then you need to restart it. Since most smart card reader are USB devices you just need to plug your USB reader andcom.apple.ifdreader is (re)started automatically.
I modified my CCID driver to log messages using
We have two options on Mac OS X: a graphical application or a command line tool.
/Applications/Utilities/Console.app .
The application icon is:
The application is easy to use. You can filter the output to only have logs from ifdreader.
Arguments:
I added a new option to the CCID driver to log this information. Since it is a sensitive information (you can see the PIN code sent to the card for example) you need the administrative privilege and edit the driver configuration fileInfo.plist . The configuration file should be /usr/libexec/SmartCardServices/drivers/ifd-ccid.bundle/Contents/Info.plist .
The new option value is 0x0080. You should have some thing like:
You will get something like:
You can note that the card power up failed 3 times.
The log criticality is available. The default level is <Warning> but can be <Error> or <Critical>.

Restarting com.apple.ifdreader
After you changed the driver configuration it may be needed to restart theFirst you need to stop the process. You can use:
$ sudo killall -SIGKILL -m .*com.apple.ifdreader
Then you need to restart it. Since most smart card reader are USB devices you just need to plug your USB reader and
Send logs using syslog(3)
Ifprintf(3)
can't be used to log messages then the normal option for a daemon is to use syslog(3)
.I modified my CCID driver to log messages using
syslog(3)
. This feature will be available in the CCID driver versions 1.4.19 and later.Get syslog logs
Now that the messages from the CCID driver are sent somewhere we must get them.We have two options on Mac OS X: a graphical application or a command line tool.
Console application
Apple provides the Console application inThe application icon is:
The application is easy to use. You can filter the output to only have logs from ifdreader.
syslog -k Sender com.apple.ifdreader
Another opiont is to use the command line toolsyslog(1)
.$ syslog -w -k Sender com.apple.ifdreader
Arguments:
- -w
The -w option causes syslog to wait for new messages. By default, syslog
prints the last 10 messages, then waits for new messages to be added to
the data store. - -k
The -k option may be followed by one, two, or three arguments. A single
argument causes a match to occur if a message has the specified key,
regardless of value. If two arguments are specified, a match occurs when
a message has exactly the specified value for a given key. For example,
to find all messages sent by the portmap process:syslog -k Sender portmap

ATR and APDU logging
Using pcscd it was possible to log APDU sent to the card and the response from the card. This service is now missing since pcscd is no more present.I added a new option to the CCID driver to log this information. Since it is a sensitive information (you can see the PIN code sent to the card for example) you need the administrative privilege and edit the driver configuration file
The new option value is 0x0080. You should have some thing like:
