Question

Kextutil failed when loading my driver on Mac-pro 10.6.8, but it's OK on iMac 10.6.8. You're appreciated if you tell me something about that! Thanks

Solution

Thanks for your reply.My iMac is running x86_64 kernel too. I got the current IOUSBFamily version when using kextlibs MyDriver64.kext. And I changed my Info.plist, made the dependency libs version(dict section) same to current version. It works.

YAN:W$kextlibs MyDriver64.kext
For all architectures:
    com.apple.iokit.IOUSBFamily = 4.2.4
    com.apple.kpi.iokit = 10.8
    com.apple.kpi.libkern = 10.8
    com.apple.kpi.mach = 10.8

And the Info.plist:

...
<dict>
    <key>com.apple.iokit.IOUSBFamily</key>
    <string>4.2</string>
    <key>com.apple.kpi.iokit</key>
    <string>10.8</string>
    <key>com.apple.kpi.libkern</key>
    <string>10.8</string>
    <key>com.apple.kpi.mach</key>
    <string>10.8</string>
</dict>
...

@Thane Norton, @pmjordan, Thanks!!!
