Show HN: Omacosy – Omarchy-style tiling desktop for macOS, no SIP

I have been using omarchy on my tower since nearly a year now, shortly after it was released first. I really love the experience I am having with it but I still use my macbook for daly work, so I wanted to recreate a similar experience on it. Thats why I created omacosy, a setup for tiling windows, custom menu bar, some themes from omarchy, focus follows mouse, focus rings around windwos, some mac flavors with trackpad events and a custom mission control overview for your workspaces.

I used AeroSpace over yabai for the tiling window manager because I didnt wanted to compromise on SIP which is a mac security feature. It is supposed to be keyboard first like omarchy to move windows organize workspaces etc The setup runs around 157mb of ram and consists of AeroSpace, Karabiner (for the super key), and five small self build swift binaries.

I am running it daily on my M1 max macbook, currently on macOS26. I havent tested it much on other macbooks or macOS versions. The install script creates a manifest file to backup what was installed before and what it installed itself, the uninstall script takes that into account to clean up the macbook to exactly the state it was in before. It needs quite some permissions for it sfunctionality which I layed our in the project readme. I wanted to be really transparent about which permissions it uses and for what reason.

I would love to get some feedback or see people trying it out and hearing your opinion. Mostly about what still doesnt feel smooth in the experience or if you find any performance issues.

Okay very cool, will try. But please remove the claude-ese from the GitHub repo. It just erodes trust.

Hey thanks, I will try to get the readme more human. I am not a great writer and I wanted to have each piece explained well and in detail. Especially about the permissioning and different features. Looking forward to your experience hope you area gonna like it.

Hyprland deserves the credit, not Omarchy. https://hypr.land/

Thats true, my bad hyprland is definitly what makes omarchy work so well. I should have stated that in the description.

Great work! I'm a fan of the hyprland setup on Omarchy and also daily on Mac! Do you have any screenshots showing some of the tiling, apps running and what not? Looks excellent!

Yes there are 4 screenshots in the readme, it's a bit long and most of them are in the bottom. There is a plain desktop one, one for the shortcuts help menu, one tiled one and one for the custom mission control. They are in the docs folder in the repo it you just wanna check out the screenshots.

No worries, curious if you already see things in the screenshots that could be improved.

How would this work on the dual monitors? Is there an option to have a secondary monitor have just one workspace while main monitor has multiple workspaces?
