Firstly, you mean macOS. Secondly, the graphical APIs are completely different, and even then macOS uses BSD userland.

##What platforms does Zed support?

As of now, we only support macOS.

We are a small team, so it’s critical for us to be laser-focused. As a startup, one of our key priorities at this early phase is learning, and right now, we’re focused on the following questions:

• What are the key features we need to get traction on any platform?
• Are our assumptions about our eventual business model valid?

While we’d love to support users on Linux and Windows, adding those platforms doesn’t really help us answer those questions. We’re investing a lot to make Zed portable, but adding other platforms comes with opportunity cost in the short-term and maintenance overhead going forward. Right now those costs don’t make sense for us.

As Zed matures on a single platform, this cost/benefit ratio will shift, and it will make sense to expand to other platforms. We hope you’ll give it a try when that happens.

As a general timeframe, you can expect us to begin work on supporting these platforms after Zed is open source, but before version 1.0. Any news will be posted to our platform-tracking issues.

Linux support is listed on their roadmap.
