Renton Posted October 25, 2015 Author Share Posted October 25, 2015 Hi spakk, unfortunaly no luck with your config :-((( Link to comment Share on other sites More sharing options...
spakk Posted October 25, 2015 Share Posted October 25, 2015 use the patched AMD7000Controller.kext for R9 270x and remove these drivers from S/L/Extensions/ ---> AppleTyMCEDriver.kext and AppleUpstreamUserClient.kext, then repair the permissions and refresh the kernel Cache with Kext Wizzard. boot flag: kext-dev-mode=1 GraphicsEnabler=No AMD7000Controller.kext.zip Link to comment Share on other sites More sharing options...
Renton Posted October 26, 2015 Author Share Posted October 26, 2015 Hello dear Spakk, 1) Have removed AppleTyMCEDriver.kext from Usb S/L/E AppleUpstreamUserClient.kext was not present on SLE. 2) Repaired permission and cache refresh 3) boot from USB with YOUR config (as private message) Now system stuck on: Sound assertion in appleHDAwidget at line 2215 Sound assertion in appleHDAwidget at line 2215 Sound assertion in appleHDAwidget at line 2215 and so on. This is a zip containing my Config and DSDT. Click! Link to comment Share on other sites More sharing options...

xenophon Posted October 26, 2015 Share Posted October 26, 2015 In my case, a Sapphire R9 270 was used without modifications (El Capitan GM). However, depending on your SMBIOS, it may be necessary to make some plist changes, as described here: https://pikeralpha.wordpress.com/2014/04/17/os-x-mavericks-10-9-3-build-13d43-seeded/ For example, if using the iMac15,1 smbios, the system boots to a black screen (but does NOT hang, it just gets disconnected from video). The solution (quoting my notes on the subject, source unknown, somewhere over at t@nym@c forum): ---- quote from t@nym@c forum ---- Problem 4: Monitor goes to sleep at the end of the boot sequence when using iMac15,1 or MacPro 6,1 system definition Fix: modify the AppleGraphicsDevicePolicy.kext 1. Using Finder locate this file /System/Library/Extensions/AppleGraphicsControl.kext 2. Right click and "Show Package Contents" 3. Now browse to /Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/ 4. Open Info.plist using TextEdit 5. Scroll down to where you see <key>ConfigMap</key> 6. For the iMac15,1 locate the board-id "Mac-42FD25EABCABB274" and change string below it from "Config2" to "none". For the MacPro6,1 you will do the same thing but for the board-id "Mac-F60DEB81FF30ACF6". 7. Save the file. 8. Rebuild the kernel cache using the following two commands in terminal: 9. sudo kextcache -system-prelinked-kernel 10. sudo kextcache -system-caches 11. 12. 13. Reboot ----- 1 Link to comment Share on other sites More sharing options...
