assuming you can get the bay drive to work you can easily build a raid. i ran into issues somewhere around Sierra 10.12.3? so i had to give up using the bay drive. i dont know what happened.

Tried the latest 20171015 release.

1) blueutil not included, found it here: http://www.frederiks...rt.de/blueutil/, hope it to be included in future releases(if no better way:p)

It did fix my sleep problem(but lid sleep seems not working?), thanks!!

2) I think 'cp' in the install scripts should be 'cp -R' because 'cp' follows symbol links by default(it works though)

3) AirDrop not working, did't check it in previous releases. Does this feature require specific model of Wifi card?

4) Some graphical glitches sometimes. Does it relate to video bios upgrade I did days ago?

1. sorry i will add blueutil to the zip

2. cp -R - not sure what was missing?

3. Airdrops works for me with Atheros - on my newer Mac i have to connect in Legacy Mode - Click on "Don't see who you're looking for?"  - which brings up "Search for an Older Mac" button - and then i see the T420

4. i dont think its a bios problem. could be an EDID issue?

@jus12  - what is your system and LCD size?


I seem to remember seeing some gfx artifacts in the High Sierra Beta. And I just noticed I must have switched to using a configuration that does NOT inject the GFX by Clover (inject set to false) - since the HD 3000 gfx is defined in the DSDT. I am also using the DSDT version that has an alternate EDID. Maybe you see if this helps? I attached the config.plist files with these changes.

sorry guys. I guess I thought it would be understood that to get to High Sierra easily, one must update ESP and kexts in /L/E before doing the upgrade. The kexts posted will run on 10.12 or 10.13


The basic procedure that seems to work:


1) update ESP and kexts with latest zip from GitHub (posted a new bundle yesterday) while still on 10.12.6

2) reboot and verify functions (audio etc)

3) directly download High Sierra from App Store to HD

4) install from HD

I don't think anyone ever got the cardreader working.


Anyway, I posted a new zip bundle on Git Hub today - the big change is for the BT KP issue in High Sierra during sleep/wake.

This is a workaround. The scripts shuts down BT before wake and turns it back on after wake (if it was on before sleep). These same scripts also turn off Wifi and Ethernet before sleeping too. Upon wake, the script checks to see if ethernet, wifi, BT were on before Sleep/Wake and then re-enables each interface that was on before sleep.  The clover scripts do the same thing essentially - but handle this for login/logout (or restart via GUI) via LoginHook and LogoutHook. 


To install, go to Utility folder and run these commands






  • Updated to Clover r4247
  • Updated Lilu and AppleALC kexts to v1.2.1 (for both Sierra and High Sierra)
  • Updated ACPIBatteryManager kext
  • Updated FakeSMC kext
  • Revised Utility Install Scripts for Sleepwatcher and Clover scripts to deal with BT in High Sierra
