Greetings all and thanks for all your excellent work here!
I have succeeded with a 10.9.0 Mavericks install on my M4400 and eventually got sleep going but this was broken by the 10.9.4 Combo Update. Apple made a feature of improved sleep in promoting the update so obviously significant modifications have been made. Have any fixes emerged for this yet?
My install method for 10.9.0:
myHack installation with the Extras folder from here: https://osxlatitude.com/index.php?/topic/2674-dell-e64006500m4400-mavericks-109-gm/?hl=m4400
(1/3 way down page)
Removed AppleACPIPlatform kext from the Extras folder (this kext is already in the Sys folder), then ran full myFix
Finally, changed the hibernate mode to 0.
Wake from sleep only ever worked by pressing the power button rather than from any keyboard keys.
