[From proton subreddit]

Today, we’re launching the Proton Drive app for Mac OS as a privacy-first alternative to iCloud Drive. It’s a significant milestone for us because Proton Drive is now available for all major platforms, including iPhone, Android, Windows, and the web app. We’re here thanks to all of your feedback on the Mac OS beta over the past few months. Thank you.
