Zotero is available for macOS, Windows, Linux, iOS, and iPadOS. If you're on a Chomebook you can use zBib instead. It's browser-based and should work anywhere.
In addition to Zotero itself, you will need the Zotero connector for whichever browser you use. Connectors are available for Chrome, Firefox, and Opera. Note that at this time the connector for Safari isn't working, and it may be difficult to use Zotero with Safari.
