Currently, Steam lacks a convenient way to quickly filter games in your library by operating system compatibility (Linux/Windows/macOS). Users, especially those who use multiple OSes, have to manually check each game or rely on third-party tools.

OS Filters in Dynamic Collections
After creating a dynamic collection (Library → Collections → Create Collection → Dynamic), add new filters:

"Linux Only"

"Windows Only"

"macOS Only"

And combined options:

"Linux + Windows" (excluding macOS)

"Windows + macOS" (excluding Linux)

etc.

Use case example: A Linux user could create a "Linux Games" collection to see only verified Linux-compatible titles (not including PROTON functionality).


When logging into a new device (or after OS reinstallation), Steam could offer a setting:
"Would you like to hide games incompatible with your current OS? Your system: [Linux/Windows/macOS]"
This wouldn't remove games from your library but would simplify navigation for users who don't want to see unavailable titles.
The option could be changed later (Settings → Interface/Library → Library Filtering).



Saves time: No need to manually check each game

Relevant for multi-OS users: Many owners use hybrid libraries

Reduces confusion: macOS/Linux users often see games they can't run

Improved convenience
