The macOS and Linux versions are in beta. Otium runs the open-source XMRig and SRBMiner miners, which some antivirus tools flag. How Otium works

Installing

Otium isn't code-signed yet: a certificate costs hundreds of dollars a year, and the free ones for open-source projects don't take apps that mine. So your computer warns you once when you install it. Here's what you'll see and what to do.

Windows
  1. If your browser says the file isn't commonly downloaded, keep it. In Edge: open the download's … menu, choose Keep, then Keep anyway (behind the arrow next to Delete).
  2. Open Otium.Desktop-win-x64-Setup.exe from your downloads. If Windows says "Windows protected your PC" (Otium isn't code-signed yet), choose More info, then Run anyway.
  3. Setup takes a few seconds and opens Otium. Choose Quick start, and add the wallet address you want to be paid to.
  4. If your antivirus stops the miners, Otium tells you and shows the one folder to allow. Don't turn your antivirus off.
  5. If Windows says Smart App Control blocked it, Otium can't run on that PC yet: Smart App Control only lets through signed apps and ones Microsoft already knows. We don't suggest turning it off for Otium.

macOS
  1. Open the installer (Otium.Desktop-osx-arm64-Setup.pkg for Apple silicon, Otium.Desktop-osx-x64-Setup.pkg for Intel). Otium isn't signed by Apple yet, so macOS says it can't verify it: choose Done.
  2. Open System Settings, then Privacy & Security. Under Security, choose Open Anyway next to the message about Otium, and confirm with your password.
  3. Follow the installer, then open Otium from Applications (if macOS asks again, do step 2 once more). Choose Quick start, and add the wallet address you want to be paid to.

Linux
  1. Make Otium.Desktop-linux-x64.AppImage executable (right-click, Properties, or chmod +x) and run it.
  2. If it doesn't start, install FUSE 2 (libfuse2, or libfuse2t64 on Ubuntu 24.04), which AppImages need.
  3. Choose Quick start, and add the wallet address you want to be paid to.
