Steam Client on APFS Case Sensitive Mac OS Drive

If you are using APFS Case Sensitive File system and trying to use Steam, it will flicker & silently fail or show the following error message:

steam requires that '~/library/application support/steam/steam.appbundle/steam/contents/macos' be on a case-insensitive filesystem.

To fix the issue, follow the instruction here.

Run from your user account, NOT ROOT!

$ brew brew install --cask steam
$ diskutil apfs addVolume disk1 APFS Steam
$ mv /Applications/Steam.app /Volumes/Steam/Steam.app
$ ln -s /Volumes/Steam/Steam.app /Applications/Steam.app
$ mv ~/Library/Application\ Support/Steam /Volumes/Steam/Library
$ ln -s /Volumes/Steam/Library ~/Library/Application\ Support/Steam

Then start Steam as normal.

cask has been changed to brew install --cask

thanks for this, this is the right solution nobody else has posted

@catb0t Thanks! I'll update the commands.

if you have steam already installed:

• ensure you have enough space to move your existing apps
• ensure steam is not running
• run next script in your terminal app

diskutil apfs addVolume disk1 APFS Steam
mv /Applications/Steam.app /Volumes/Steam/Steam.app
ln -s /Volumes/Steam/Steam.app /Applications/Steam.app
mv ~/Library/Application\ Support/Steam /Volumes/Steam/Library
ln -s /Volumes/Steam/Library ~/Library/Application\ Support/Steam

Please be patient, it may take some time to finish, although it steam may cleanup all the downloaded games after you start it.

Thanks @katsanva! Super useful <3
