When Apple first introduced the smart card support in Mac OS X 10.2 Jaguar (August 2002) pcsc-lite was at version 1.0.x and I just started to add my patches to it. At that time the author and maintainer of pcsc-lite was David Corcoran.
In this article we will do some archaeology work. Apple moved the SmartCardServices to the SmartCard Services public project in January 2009 at the time of Leopard 10.5. The first tag on source code available in the subversion repository is for OSX-10.5.6. The detailed history of the source code before that version is not publicly available and must be reverse engineered "by hand".
On the "official" pcsc-lite side, the oldest tagged version is 1.1.2-beta1 from September 2002.
The original pcsc-lite and ancestor of Apple pcsc-lite is called "official" pcsc-lite. The "official" pcsc-lite is used mainly on GNU/Linux (and GNU/Linux distributions) and is also used on FreeBSD, NetBSD, OpenBSD, Android, and maybe other Unix-like systems I don't know about.
Oracle (ex-Sun) has its own forked version of pcsc-lite for Solaris. An old version of this source code is available in the Solaris branch.

Diffstat between 10.4.11 PowerPC and 10.4.11 x86
Changes:
The major change here is the support of PowerPC and Intel CPUs at the same time.
On an Intel Mac it is possible to run a PowerPC appplication using Rosetta. In that case the application code is for PowerPC but the PC/SC daemon is running x86 code (native code). The daemon needs to convert the byte order in all the messages exchanged between the client (PowerPC code) and server (x86 code).

Terminology
The pcsc-lite provided by Apple is called, in this article, Apple pcsc-lite.The original pcsc-lite and ancestor of Apple pcsc-lite is called "official" pcsc-lite. The "official" pcsc-lite is used mainly on GNU/Linux (and GNU/Linux distributions) and is also used on FreeBSD, NetBSD, OpenBSD, Android, and maybe other Unix-like systems I don't know about.
Oracle (ex-Sun) has its own forked version of pcsc-lite for Solaris. An old version of this source code is available in the Solaris branch.

The
PCSCLITE_VERSION_NUMBER in src/pcsclite.h is "1.1.1". The same 1.1.1 version of the "official" pcsc-lite was released 5 Jun, 2002. I wrote above I do not have the version 1.1.1 in the subversion history. So we will use version 1.1.2-beta1 instead.A diffstat between the two versions gives us:

uint8_t,uint16_t,uint32_ttypes to support 32 and 64 bits client applications with the same pcscd server
The major change here is the support of PowerPC and Intel CPUs at the same time.
On an Intel Mac it is possible to run a PowerPC appplication using Rosetta. In that case the application code is for PowerPC but the PC/SC daemon is running x86 code (native code).

Changes:
- install the
sc_authcommand used to configure a smart card Mac OS X login - support colored logs but only on Linux terminals. Apple just reused
debuglog.cfrom pcsc-lite 1.3.3 - use
secdebug()to log debug messages (visible using dtrace) - reuse
ifdwrapper.c,prothandler.candpcscdaemon.cfrom pcsc-lite 1.4.0 - integrate with securityd
- create new C++ files:
eventhandler.cpphotplug_macosx.cppPCSCDevice.cpppcscdmonitor.cppPCSCDriverBundle.cppPCSCDriverBundles.cpppcscdserver.cppreader.cppreaderstate.cppsys_macosx.cppwinscard_msg.cppxiodevices.cpp
The new file
pcscdmonitor.cpp is the link with securityd.From the source code:
pcscmonitor - use PCSC to monitor smartcard reader/card state for securityd
PCSCDMonitor is the "glue" between PCSC and the securityd objects representing smartcard-related things. Its job is to manage the daemon and translate real-world events (such as card and device insertions) into the securityd object web.
PCSCDMonitor uses multiple inheritance to the hilt. It is (among others)
(*) A notification listener, to listen to pcscd state notifications
(*) A MachServer::Timer, to handle timed actions
(*) A NotificationPort::Receiver, to get IOKit notifications of device insertions
This version of Apple pcsc-lite is a major deviation from the "official" pcsc-lite.
At the same time Apple merged code from the "official" pcsc-lite.

Changes:
- Apple removed the code of the CCID driver from SmartCardServices
- Apple now provides my CCID driver instead of another (limited) CCID driver
- this version of SmartCardServices includes patches I made in pcsc-lite 1.5.0 and I backported to the Apple version (
ifdwrapper.candwinscard.c) since I am a member of the SmartCardServices project - support 32 and 64-bits smart card reader driver. pcscd will restart in 32-bits if a 32-bits only driver is found
- use
OSSwapHostToBigInt64()to support big/little endian conversion and also 32/64 bits conversion

Changes:
- some bugs fixes I made in the "official" pcsc-lite and I then ported to Apple version of pcsc-lite. See my blog article for details.
- the CCID driver has been updated from 1.3.8 to 1.3.11
10.8 Mountain Lion
July 2012Blog article "Mac OS X Mountain Lion and smart card status"
SmartCardServices-55105
No change in the source code.
10.9 Mavericks
October 2013Blog article "OS X Mavericks and smart cards status"
SmartCardServices-55111
Changes:
- The ability to respawn in 32-bits to run a 32-bits only driver (introduced in Snow Leopard) has been removed
- The CCID driver is now in 64-bits but the version is still 1.3.11
Conclusion
The evolution of Apple pcsc-lite is quite different from the evolution of the "official" pcsc-lite.In a next article I will describe the differences between the 2 projects after more than 10 years of evolution.
