Made for Windows. On a Mac and Linux too.

Windows: three ways to have it

On 64-bit Windows 10 and 11, MDM is the stable, recommended build. The download page offers three files:

• The installer (setup.exe), the one to pick unless you have a reason not to. It installs for you alone without administrator rights, or for everyone, and can set up browser integration and open .torrent files and magnet links with MDM.
• The portable copy (portable.zip), which runs from any folder.
• The plain zip (x64.zip), the same programs without an installer.

Help → Check for updates → Update now downloads a new version, checks its signature, puts it in place and restarts, for the setup and both zips.

Portable: everything in one folder

Unzip the portable copy anywhere, a USB stick included. The download list, the settings, the video helpers and torrent data stay in a data folder next to the program, and nothing is written to the registry. Two things need the installer instead: starting with Windows, and taking downloads from the browser, since both go through the registry. Carry MDM on a USB stick shows the set-up.

Mac and Linux: what you get today

Today's files marked -experimental are for macOS 11 and later, on Apple Silicon or Intel, and for Linux on x86-64: an AppImage for most distributions, a .deb for Ubuntu, Debian, Mint and Pop!_OS, an .rpm for Fedora, openSUSE and RHEL, and a .tar.gz of the plain programs. Please tell us how it went, good or bad.

There, MDM connects itself to your browsers at each start, has its tray icon, follows the system's light or dark look and uses the system's fonts and ffmpeg. The Mac app isn't notarized by Apple yet, so macOS asks before its first start: right-click it and choose Open (on macOS 15 and later, System Settings → Privacy & Security → Open Anyway). A .deb or .rpm update opens in the system's installer. A few parts work only on Windows, and the help says so where it matters.

Linux, checked on four desktops

Linux won't be experimental any more: every change is now checked on a Linux desktop as well as on Windows. GNOME, KDE Plasma, Xfce and Cinnamon were checked window by window: the tray icon and its menu, Minimize to the notification area, Dark Mode support following the desktop, and the browsers handing downloads over (Ubuntu's Snap Firefox, Google Chrome and Brave). A Wayland session runs MDM through XWayland, so menus open under their titles, on tiling compositors such as sway too. The .deb and .rpm were installed in clean Ubuntu 24.04, Debian 12 and Fedora 45 systems and bring everything MDM needs; from the AppImage or the .tar.gz, a missing library is named at start with the command that installs it. Update now asks the package manager which package MDM is.

What's left: the Flatpak Firefox isn't checked yet; screen readers (Orca) don't read MDM's windows on Linux yet; and native Wayland windows can't place menus, so XWayland stays the default. macOS stays experimental: its builds are made and tested by GitHub Actions, not yet on a Mac of ours.

Smaller Mac downloads, lighter Linux updates

The Mac gets two smaller downloads, one for Apple Silicon and one for Intel, instead of one universal .dmg of 80 MB. From 0.2.4 or older, update the Mac once by hand: Download in Check for updates opens the release, where you pick your Mac's file. The AppImage can update through AppImageLauncher, Gear Lever and AppImageUpdate, which fetch only the parts that changed. Linux can draw with Vulkan and macOS with Metal, from View → Draw with, while OpenGL stays the default there. In a Wayland session, MDM runs through XWayland so its menus open where you click.
