Hi everyone,
**The first “alpha 1” preview release of Cylc 8 is available for viewing and testing by interested users.**
Cylc-8 ([described here](https://cylc.github.io/cylc-admin/cylc-8-architecture)) is much easier to install than Cylc-7 - just follow the [instructions in the cylc-conda README file](https://github.com/cylc/cylc-conda#cylc-8-conda-installation-instructions). Please read [current limitations](https://github.com/cylc/cylc-conda#current-limitations) first. Feedback welcome!
Thanks to the team for the brilliant job so far 💐
Hilary

Great! Yes, we don’t support MS Windows at this stage.

(Sorry I’ll reply on @hilary.j.oliver’s behalf, since he is on holiday this week so probably will not be able to rely for a while):
No, we only support Linux platforms at the moment.

We don’t officially support Mac OS at present, however, I have successfully run Cylc7 on (now quite old) Mac OS 10.11. Have heard from users on Mac OS, this forum might be the best way to reach them. I think newer versions of Mac OS may require DNS configuration to work with Cylc.
If trying to install on Mac OS, Cylc requires some of the GNU coreutils tools.
See the instructions on Homebrew about adding these to your `$PATH`:

is ‘graph’ supported to produce a visual of the graph strings?
so far, i have yet, to produce one of these on any platform (Linux, OSX) using versions 7 and now 8.
(cylc1) $ cylc --version
8.0a1
(cylc1) cylc graph t.01
UserInputError: Only the --reference use cases are supported

Cylc “graph” is a GUI feature which will be implemented in the new browser-based GUI. The old `cylc graph` command has been retained for its `--reference` functionality which is used in testing.
