Recommended Posts

currently couple things not working

- DisplayPort not working,  HDMI port works



- can I copy my el capitan on second partition to boot, with current r4359 clover ?

that would be a great help

- looks like lilu is not working


E7450 i5-5300U , A17 bios

- unifail install,  high Sierra 10.13 , multifail , clover r4359, 

- dsdt.aml, ssdt, from bootpack E7450_HD5500_Only_A17_HS.zip  

- currently MacBook Air , ssdtprgen says it's mismatch, should be MacBook Pro 12,1


appreciate any help, pointers 

- rules -> what does TMX stand for ?

See here regarding wifi

We don't support TMX (tonycrapx) stuff here so if you're using it ( unifail/mutifail), then you should ask for support there.

Since you're using my files, you should include the kexts folder as well to have audio, graphics, wifi ...working.

Kexts in ../kexts/Other/LE should be moved or copy to /Library/Extensions

Run permission fix and rebuild cache afterward


Dual boot should be supported...

thanks Jake! 


update notes:

- Wifi                - Works now

- Bluetooth      - not working now

- sound            - not working

- DisplayPort   - not working

- laptop display -> works after sleep wake

- copied HS on second partion, and EFI r4359, -> does not see El Capitan partition. 


- did try config.plist from bootpack E7450_HD5500_Only_A17_HS.zip --> got KP

​- did try install , vanilla clover r4359  -> got no boot entries



- I will trim back my current config.plist down to match  the bootpack config.plist 

- ssdt.aml, create new (ssdtprgen.sh) , for macbook12,1 since processor does not match with MacBook Air7,2 from bootpack


have no idea ,

- how you guys install from scratch, did not see it in the install guide

- or install vanilla clover , with boot entries


% sudo kextcache -I /

hope that does the trick doing the kextcache update and permissions fix



... sorry old noob at play, thanks

- sound - working 

  -> copied AppleHDA_ALC293.kext /Library/Extensions 

 -> chmod, chown +  sudo kextcache -I /

-> note bootpack does not have AppleHDA_ALC293.kext. in bootpack kext/LE directory

 - instructions -> Audio with patched AppleHDA -> little vague for a noob


interesting, after all 293 patch,  the sound on monitor over HDMI disappears 


- laptop screen , still scrambled , till sleep/wake,  looks like LiLu , IntelGraphicsDVMTFixup.kext thing is not working from clover 

- Mini DisplayPort not working 

- have not tried docking station

thanks Jake,



--> Kexts in /EFI/Clover/kexts/Other/LE should be moved or copied to /Library/Extensions. Then repair permission and rebuild cache.


need to figure out IntelGraphicsDVMTFixup.kext  ,and scaled screen  after boot


-> looks like max freq is 2.2GHZ 

 does not look it ever gets to 2.7ghz turbo


post your E7450 Geekbench 4

and check with intel power gadget 


it be nice if the displayPort would work again , since the HDMI is not going to do 4k


attached files


Geekbench 4

Made a mistake on DSDT, bootpack is now updated.

Had HDEF/HDAU layout-id 1 on DSDT and 11 on Config.plist, it's now sync'd.

New bootpack uses Lilu + AppleALC for audio

Remove AppleHDA_ALC293.kext from /L/E

Repair permission and rebuild cache


This should fix the HDMI/DP audio

If you're going to generate SSDT for MBP12,1, make sure you change SMBIOS in Config file first.

Then reboot before generating.
