Guidance on installing Mavericks on a Toshiba Z930 PT23LA-01F00N

[RehabMan]

I have a device with the same type Z930 PT234L-03U036. I have tried to retrieve hardware data with CPU-Z, HWMonitor and EDID Dumping from Nullsoft (On Windows 7 64bit). The files included. For VGA HD4000 works well (Intel 0x01660003), and so with PS2 keyboard control (VodooPS2), Audio with Realtek HDA271, LAN Intel (mausi driver), WiFi (Atheros). However I am still have a (huge) problem with the Brightness controller. The system I've installed is Sierra 10.12.0. What procedure should I do to be able to turn the brightness controller?

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

From where did you download macOS?
On what hardware did you create your USB installer?
