Hello,
i have a Acer 5740g and I'm using this modded Phoenix BIOS (the one with just the unlocked Intel menu, 1.28) 
and i am having trouble keeping the option "Legacy USB Support" under "Intel>PCH USB Control Sub-Menu" disabled.

each time i disable it, then boot into any Mac OS, the option only sticks until i reboot (note that other menu items don't revert after reboot).
I am hoping this could could be fixed by further modding, as the bootloader's (Clover) disable legacy USB feature does not have the same effect. 
long story, but it allows my laptop to sleep and have PS2 working at the same time...
Any help is greatly appreciated.

Edit: This ended up being a DSDT issue with LPC. Still have no clue how it managed to change a BIOS setting. 10.13 sleeping soundly Smile
