A question about default BG:EE and IWD:EE install directory in GOG and Steam releases (windows+mac)

Hello,
I need to know all default directories for these 2 games for my mods. Default windows Beamdog launcher dirs for BG:EE are:

C:\Program Files (x86)\BeamDog\Games\00766
C:\Program Files (x86)\Baldur's Gate Enhanced Edition\Data\00766
C:\Program Files\BeamDog\Games\00766
C:\Program Files\Baldur's Gate Enhanced Edition\Data\00766

And for IWD:EE

C:\Program Files (x86)\BeamDog\Games\00798
C:\Program Files (x86)\Icewind Dale Enhanced Edition\Data\00798
C:\Program Files\BeamDog\Games\00798
C:\Program Files\Icewind Dale Enhanced Edition\Data\00798

I'm also aware about default BG:EE one for MACS:

Applications/Baldur\'s\ Gate-EE/Game\ Data/00777/Baldur\'s\ Gate\ -\ Enhanced\ Edition.app/Contents/Resources

What I still need to know are following dirs:
- default dirs for GOG and Steam releases of BG:EE and IWD:EE (windows and mac)
- default dirs for Beamdog launcher of IWD:EE (mac)

Thanks in advance.
