morpheousman Posted November 26, 2015 Share Posted November 26, 2015 Almost have this working with Dual-boot Yosemite, Windows 10. Have a couple of issues to clean up, mostly battery status. Battery status still not working. Will come on once in a while. Unplug power adapter It show the "X" then sometimes LCD will dim and bat status will work, but then a few seconds later, lcd screen will go back to bright, and bat status is gone. So, lcd screen is not always dimming with AC unplugged, will dim, and then go bright every few seconds. EDIT: This seems to have stopped? LCD will sometimes pixelate badly on boot up, and need to reboot to fix. Will also pixelate and have lines on LCD during use. 1600 x 900 HD+ LCD, HD3000, i5-2520m Using Dell DW1520 Wifi, so I changed smbios to Macbook Air 5.2 (not sure if that matters). Kexts used from this Guide: https://osxlatitude.com/index.php?/topic/6935-guide-e6420-os-x-yosemite-10100-finalgm-3pb-4/ Using Clover Legacy boot. All kexts installed to S/L/E Using DSDT from this Guide: https://osxlatitude.com/index.php?/topic/7091-dell-latitude-e6420-with-i5-2410m-hd3000-and-1600x900-lcd-mavericks/ Using ssdt from this Guide: https://osxlatitude.com/index.php?/topic/7914-dell-latitude-e6220-with-intel-i5-2520m-hd3000-and-1366x768-lcd-mavericksyosemite/ Not sure if DSDT has this patch: into method label _STA parent_label BAT1 replace_content begin Return (Zero) end; into method label _STA parent_label BAT2 replace_content begin Return (Zero) end; New Way and Regions unchecked.

morpheousman Posted November 28, 2015 Share Posted November 28, 2015 Try this Thanks! The battery status is now working. Now only need to figure out why this LCD acts crazy sometimes. I will try to get a screen shot when it does it. Link to comment Share on other sites More sharing options...
morpheousman Posted November 29, 2015 Share Posted November 29, 2015 Here is a sample of the LCD screen, artifacts distortion. Sometimes it can take up most of the screen, requiring one or more reboots to remove, and distortion can return at any time. Link to comment Share on other sites More sharing options...
morpheousman Posted November 30, 2015 Share Posted November 30, 2015 Found a solution to the Video problems. Seems that this is an issue with HD3000 Yosemite/El Capitan, and Clover. The fix is: Boot Arg: Slide=0, and Inject Intel. 1 Link to comment Share on other sites More sharing options...
morpheousman Posted December 2, 2015 Share Posted December 2, 2015 Okay, looks like I just about have this install done. Yosemite 10.10.5 Clover. Generated a SSDT with latest ssdtPRGen.sh. I had to change from SMbios 5.2 to SMbios 8.2 to get SpeedStep working. Changing to SM8.2 meant that my Dell DW1520 WiFi stopped working, so I needed to add a Clover Kext Patch for the AirPortBrcm4360 to get my Dell DW1520 WiFi working again. In Clover Configurator, KextsToPatch: Find: 4D61632D32453646414239363536364645353843 Replace: 4D61632D39343234354133393430433931433830 Comment: DW1520 Whitelist Patch (MBP8,2) SpeedStep now Working, along with: Sleep Battery Status Dell Dw1520 Wifi HD3000 Graphics with 1600x900 HD+ LCD now working without picture artifacts. (Boot Arg Slide=0) HDMI Touchpad (Trackpad), with Double-Tap, and Two Finger Scroll Onboard Dell375 Bluetooth OOB SD Cardslot Seems to be a very functional Hackntosh. I might leave it alone for a week or two, and then try to install El Capitan. Link to comment Share on other sites More sharing options...
dsosx Posted February 20, 2016 Share Posted February 20, 2016 @morpheousman Can you post your final SSDT? To create it, did you just take the SSDT from the link in post 264 and just change the mac model from a macbookpro 5.2 to a macbookpro 8.2 using the ssdtPRGen.sh on your Hackintosh after the initial install was done? Thanks Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 20, 2016 Moderators Share Posted February 20, 2016 No, you should generate it after you have changed your SMBIOS to MBP8,2 Link to comment Share on other sites More sharing options...
