Platforms

A setup compiles for one platform at a time. Apply always uses the computer you’re on; the setup editor’s Preview for menu shows what the same setup would install anywhere else.

Platform	Notes
macOS (Apple Silicon)	mise tools, Homebrew packages, and Mac apps from Homebrew Cask — all installed by mise, no Homebrew needed. git and curl come with macOS.
macOS (Intel)	The same, except mise can’t install Homebrew packages (formulas) on Intel; the preview lists anything left out. Mac apps still install.
Linux	mise tools, then Homebrew packages (installed by mise into /home/linuxbrew/.linuxbrew), then apt.
Windows	mise tools, plus winget or Scoop packages.
WSL	Treated as Linux: a setup applied inside WSL installs Linux tools there. Desktop apps belong on the Windows side.

How providers are chosen

Each tool in the catalog lists the ways it can be installed and the platforms each one supports. powermise picks exactly one per tool, in this order:

1. A mise tool — goes in the file’s [tools] with a pinned version.
2. Comes with the system — nothing to install (git and curl on macOS).
3. Homebrew formula, then Homebrew cask (Mac apps), then apt, then winget, then Scoop — goes in [bootstrap.packages], which mise bootstrap installs. mise installs Homebrew packages and casks itself, so Homebrew doesn’t need to be installed. They can’t be pinned, so they’re latest.

apt comes after Homebrew because every apt install needs an administrator password. On a machine that already has the package, apt does nothing.

If a tool has no provider for the platform, the editor reports it before anything is saved, and harnesses that don’t support the platform can’t be picked for it.

Linux and WSL: the one-time Homebrew setup

mise puts Homebrew packages in /home/linuxbrew/.linuxbrew, and creating that folder needs sudo once. The app can’t type a password, so when a setup needs Homebrew and the folder isn’t ready, Apply becomes Apply in Terminal: the first install runs in your terminal app, where sudo can ask. After that, installs run in the app. To do it yourself:

sudo mkdir -p /home/linuxbrew/.linuxbrew && sudo chown -R "$USER" /home/linuxbrew

On Linux the Apply sheet also offers Run in Terminal, for apt packages that aren’t installed yet.

Support status

Platform	Status
macOS	Compiled fragments verified against real mise 2026.10 in CI; a clean-machine apply is still an open acceptance gate.
Linux	Verified against real mise in CI; not yet clean-machine tested.
Windows	Compiles and previews; no real Windows installs are claimed until clean-machine evidence exists.
WSL	Compiles as its own target; not yet clean-machine tested.
