It's been 102 since 10.7. There's no need to manually enter it in as it defaults to it if the version is 10.7+ and not coded in as being changed. If anything the kext may need to be updated with new headers in 10.8.3 but probably not.
The version on googlecode that I last updated in July 2012 still works perfectly in 10.8.3. Just did a test run on my laptop, and it slept and woke without issues.
ReportCrash <Error>: LaunchServices/5123589: Unable to lookup coreservices session port for session 0x186a0 uid=0 euid=0
eportCrash <Error>: failed looking up LS service ( scCreateSystemService returned MACH_PORT_NULL, called from SetupCoreApplicationServicesCommunicationPort, so using client-side NULL calls.
I started having this same issue in 12D76 - even with App Store release of 10.8.3.
So far I've figured out:
1) It only happens when booting from kernelcache. 2) If you have FileNVRAM loading with chameleon, if you try booting nonkernelcache (UseKernelCache=No) after booting via kernelcache, you will still have the issue.
You need to not load FileNVRAM and boot without kernelcache in order to get binaries that are kext_tools related to run again (kextcache, kextd, kextload, kextutil).
*edit: Removing the generated nvram.plist in /Extra works as well; it will just be remade next boot and will work fine. So you don't have to get rid of FileNVRAM. Didn't think about this. derp.*
So the question is why is this happening to some people but not close at all to most people, in specifically 10.8.3 builds? I do not have any clue at all. Not yet anyway. I'll be spending the next few days finding out wtf is wrong. I just wanted to post this here so anyone getting this will know how to get things running fine again (not including iMessages now, unfortunately).
