API Differences between 10.13 and 10.14The differences should be listed in the developer page macOS Mojave 10.14.
The changes for Mojave are not yet available.
PC/SCSince Yosemite (10.10) the PC/SC layer is no more a fork of pcsc-lite. So comparing versions with pcsc-lite is useless.
$ cat /System/Library/Frameworks/PCSC.framework/Versions/A/Resources/version.plist <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>BuildAliasOf</key> <string>CryptoTokenKit</string> <key>BuildVersion</key> <string>163</string> <key>CFBundleShortVersionString</key> <string>8.0</string> <key>CFBundleVersion</key> <string>1</string> <key>ProjectName</key> <string>SmartCardServices</string> <key>SourceVersion</key> <string>281200021000000</string> </dict> </plist>
The BuildVersion moved from 10 in Sierra 10.13.6 to 163 in Mojave 10.14.0. Maybe Apple made 163 - 10 = 153 internal/alpha/beta releases?
The SourceVersion moved from 281050022000000 in High Sierra 10.13.6 to 281200021000000 in Mojave 10.14.0. I have no idea how to parse or use this information.
PC/SC Bugs fixedThese bugs were found in High Sierra are now fixed in Mojave:
- Typo in error message from PC/SC call pcsc_stringify_error(), bug #40995115.
pcsc_stringify_error()returned "Unkown error" instead of ""UnkNown error" for unknown error codes.
CryptoTokenKitCryptoTokenKit is the native smart card API since the complete rewrite in macOS Yosemite 10.10 (OS X Yosemite BETA and smart cards status).
$ strings /System/Library/Frameworks/CryptoTokenKit.framework/CryptoTokenKit | grep BuildRoot /BuildRoot/Library/Caches/com.apple.xbs/Sources/CryptoTokenKit/CryptoTokenKit-281.200.21/CryptoTokenKit/TKToken.m /BuildRoot/Library/Caches/com.apple.xbs/Sources/CryptoTokenKit/CryptoTokenKit-281.200.21/CryptoTokenKit/TKSmartCard.m /BuildRoot/Library/Caches/com.apple.xbs/Sources/CryptoTokenKit/CryptoTokenKit-281.200.21/CryptoTokenKit/TKTokenSession.m
In Mojave CryptoTokenKit source code is at version 281.200.21. It was at version 281.1.1 in High Sierra 10.13.0 and 281.50.22 in High Sierra 10.13.6.
Since the source code is not available I can't write much more than that.
CCID driverDriver version: 1.4.27.
$ grep -A 1 CFBundleShortVersionString /usr/libexec/SmartCardServices/drivers/ifd-ccid.bundle/Contents/Info.plist <key>CFBundleShortVersionString</key> <string>1.4.27</string>
This is the exact same version as in Hight Sierra 10.13.0.
Note that the CCID version 1.4.28 was released in October 2017 and version 1.4.29 in February 2018. Apple had plenty of time to upgrade the CCID driver. This is surprising.
The current version of the CCID driver is 1.4.30. This version was released 5 days before Mojave so I was not expecting to see this version included in Mojave.
ConclusionNo much visible changes in the smart card layer in macOS Mojave.
It is surprising Apple has not upgraded the CCID driver since the previous major version of macOS. I understand this major version of macOS is not a revolution but more a stabilisation of macOS.
