Installed DP 4 - had to apply RTC and TRIM fixes again as they disappeared.
Everything seems to be working fine.
It appears that it is significantly faster startup in DP4 than in any other previous DP version and faster than in ML. By this I mean the time from the moment the Apple sign appears to the moment you are presented with login screen is significantly shorter.
Installed GenericUSBXHCI in DP3 and USB3 is working fine. Sleep is not affected - functional.
p.s. After trying all sorts of tricks I could possibly find regarding enabling Face Time and iMessages, iMessages not working. I managed to get them working in DP1 then it stopped when I installed DP2. I got it working again after I signed off iMessages from my genuine MBP. Later, when I changed network configuration it stopped working again. Since then no success! I reinstalled from scratch and changed serial number using the Champlist application - rejected! Then installed DP3 on MBP using an external USB SSD, moved to Hackintosh installed Chameleon, FakeSMC. Got recovery partition, and all the bells and whistles, including FaceTime working but iMessage rejects every option on this MB (GA-X58-UD7)!?
Independently tried to install 10.9 on RAID 0 (two SATA 3 SSDs) by copying an existing working disk image to RAID 0, then installing Chameleon on both drives, and pointing Chameleon to RAID ID. No success to pass even boot - OSX "panic attack".
