Which OSX version? 10.11?

fremachuca ,

Do you mean the Steam overlay (shift + tab) or overlay notifications (achievemnts/messages popup)?

(If you want you can send me a screenshot via PM)

Check this

Prominent , just create a file named installscript.vdf and call your .bat file as uninstall process

Doc: Steamworks -> Making and using Install Scripts -> Run Process on Uninstall.

create a .bat file and run it from your steam uninstall script

eg: create a file named "clearfiles.bat" and paste this code

RMDIR /S /Q "%LocalAppData%\GameName\User Data\"[/code:1c8mqtd1]
GameName is your app name

Note: you remove your localstorage data too

Yes you need to add the file libsteam_api.dylib from osx32 folder (for 32 and 64b)

Regards,

andreyin , the OSX 64b support will be added in next update (this week end or monday)

colin Jones , until the next update yes you can do this.

I didn't test enough this feature to be sure but I think the issue is caused by H.264 codec used by steam Link. These codecs are not included with nw.js due to the license needed for them.

You could use Steam installscript in order to install redist (directx,msvc,fonts...) or custom process AND to uninstall what you want (steam can run a process when you uninstall a game

Related to Steam link and/or NW.js not BigPicture itself

Sidenote: Steam overlay don't work with electron on win7/OSx/Linux (maybe fixed with the newest version of electron)
