I'm not sure, that I found correct answer... ig-platform-id in config.plist is <key>Graphics</key> <dict> <key>DualLink</key> <integer>0</integer> <key>Inject</key> <dict> <key>ATI</key> <false/> <key>Intel</key> <true/> <key>NVidia</key> <false/> </dict> <key>NvidiaSingle</key> <false/> <key>ig-platform-id</key> <string>0xa260006</string> </dict> did you mean it ? 0xa26006 ? Jake Lo, I don't think so (don't remember).. but I now I removed AppleIntelFramebufferAzul and replaced it by kext from installation usb drive (from /S /L /E folder). I didn't find any AppleIntelHD5000Graphics on installation drive...

genjineos, thanx for your answer, but I tried to do the same steps before I wrote here. At the moment I rebuilded the system cache and as result lags with mouse pointer, safari tabs and other windows are removed. OS works faster - It works as it should be work, but something is wrong... I can't open video-files (tried .mov, .avi and .mpg extensions) AppleIntelFramebufferAzul and AppleIntelHD5000Graphics are in /S/L/E

Jake Lo or Hervé - can you help me ? my english not good, but I'll try to describe my trouble I'm Dell 7537 owner (Intel Core i7-4510U, 8 GB DDR3, 1 TB HDD, NVIDIA GeForce GT 750M / Intel HD 4400 ). I used before Mavericks and it worked fine (aprox over 2 years), but a few days ago OS was crashed and now I have installed Yosemite now (10.10.5), but it doesn't work fine (however I have installed kexts from guide): no sound (but I tried to install different kexts - like modified by you here, and kext from HVT (ALC 283 v2)), OS works slowly (seems like trouble with graphical card) - I have installed HD 4400 / 4600 fix kexts from it. Now OS works a little faster, but a lot better in terms of mouse pointer but still not fast and smooth as Maverick I worked before. The same with application windows or switching between tabs - it works with lags (for example in Safari when I move mouse pointer to tab - pointer is hidden behind tab for a few second). I attached my config and DSDT and patched SSDT-files archive.zip

so easy solution thank you!

Jake Lo, yeahhh! You helped me (video is without freezs), but now I have new trouble, which was after OS upgrading: Menu-bar in top left-side is strange (watch attached file): text-color is purple without correct contour and text-background is with lags (stripes)... Maybe you have next solution for me ?

Jake Lo thnx for answering. Can you describe how i can restore vanilla FB ?

are you sure that you open .dsl files (not .aml) ?

Hello all! Sorry, my english is not good, but I'll try to describe my trouble: I was updated 10.9.2 to 10.9.4, after update installation I've done all steps of the manual at the beginning in this topic. Now I have only one trouble: video-files (checked by .avi, .mkv,.mp4 files) not opened (vlc, quickmovie. Videos in youtube (and others flashplayers) shows with freezes (something like low FPS), but sound works correctly. Same trouble in games: sound works properly (headphones port works fine), but video is very very slow... Cursor moves also without any lags, Launchpad manu opens with freezes (slowly) In Windows this problem would be solved by graphic-card driver reinstalling But how I can fix it on my hackintosh ( Dell Inspiron 7537, HD Graphics 4400 / nVidia GeForce GT 750M) ?
