Installation

Windows

download the latest release package: Releases

Linux

make sure python 3.10 or newer is installed on your system.
Download the Restim source code, and execute run.sh

Mac

Grab the latest .dmg from Releases — Restim-arm64.dmg for Apple Silicon (M1+) or Restim-x86_64.dmg for Intel. Open the DMG and drag Restim.app to Applications.

First launch — macOS will block the app because it's not signed with an Apple Developer ID. Pick one of:

Option A — System Settings (no terminal required):

1. Double-click Restim in Applications. You'll get a dialog saying it can't be opened or was blocked — dismiss it.
2. Open System Settings → Privacy & Security, scroll down to the Security section. You'll see a message about Restim being blocked, with an Open Anyway button. Click it.
3. Confirm with Touch ID or your password, then click Open in the final dialog.

Option B — one-line terminal command:

Open Terminal and paste:

xattr -dr com.apple.quarantine /Applications/Restim.app

Then double-click the app normally. This removes the "downloaded from the internet" flag that triggers Gatekeeper; it does not disable Gatekeeper system-wide or require sudo.

Subsequent launches are normal double-clicks either way.

Older guides mention a "right-click → Open" shortcut. That path was removed in macOS Sequoia (15) for apps without a Developer ID signature; use one of the options above instead.

Development:

install PyCharm and python 3.10 or newer. Open Settings, python interpreter, and configure a new venv. Navigate to requirements.txt and install the dependencies. Then run restim.py.
