E7440: some issues with Sierra


Alex Rivera

Recommended Posts

I'm having trouble with bluetooth after sleep. I use DW1550 and bluetooth is properly loaded when system is booted but I get bluetooth unavailable when waken from sleep. I managed to pinpoint that usb is at fault. When booted the 2070 chip is listed in usb devices but after sleep it is not there anymore. I really don't know where to start debugging? Clover? DSDT? SSDT? Maybe I miss a kext. I'm using Bluetooth firmware uploader 3.1.5 from this forum, same issue is with Rehabman's version. 
Please point me a direction to go to

@kfiatos: did you patch your DSDT USB controllers with power management code?

 

@Alex Rivera: one way to fix the iTunes movies issues is to use the Shiki kext. Known to fix green screen problems on Ivy Bridge and can also fix issues on Haswell iGPUs.
