I'm using OpenCore bootloader, all works fine.

OC EFI: https://github.com/davordragic/z87-hd3-hackintosh-opencore/tree/master/EFI

Only problem I have is using Logitech Keys and MX3 on same receiver if connected to monitor (Philips 346P1CRH).
It works, but mouse is lagging. If connected directly to PC, works fine, smooth (despite beeing futher away from mouse).
No idea where to look for an issue. USB looks to works fine.If I add (git history) USB mapping, mouse and keyboard even stop working on monitor (regular storage usb still works).

PS: monitor has a mic and camera
This is USB ports, when Logitech unify connected to PC.

... just noticed, might be a problem, that USB received does not get enoght power?
If I move mouse directly under monitor (10cm away), looks like it works fine.
On other hand, keyboard on same logitech unify dongle works completly fine anywhere connected.
How to check how much power does USB receive?

Noticed USB Monitor Camera is using full 500mA current and if I closed camera, mouse starts working fine...
I guess too much deviced on 1 hub for USB2.0 (max 500mA).

I need to figure out how to get more current to USB hub on monitor. USB3.x (1100mA)

Hi.

You will find your task very difficult. Sadly USB power delivery to hubs rarely works. A powered hub is fine but there may not be one in your monitor.

All you can do on your PC is to create an SSDT-USBX.aml to accompany the USB configuration you are using.

Post your EFI here as a zip attachment and we can check it. (There is no need to send people off-site).

:)
