Stationary Beta

Install & ride

Beta: behavior may change and bugs or data loss are possible. Export important rides and back up your Mac before installing updates.

Install from the website

Download availability and the verified minimum macOS version are shown on the download page. Builds support Apple silicon, not Intel Macs.

  1. Download the DMG and its checksum file from the linked GitHub Release. Verify the download if desired: in its folder, run shasum -a 256 -c SHA256SUMS. Matching hashes confirm the bytes, not publisher identity or malware freedom.
  2. Open the DMG and drag Stationary into Applications. Eject the disk image.
  3. Open the installed app from Applications. It is not Apple-notarized or signed with a Developer ID certificate; macOS may block it.
  4. Only if you trust the download, follow Apple's official per-app exception instructions: after trying to open it, use System Settings > Privacy & Security > Open Anyway, then confirm.

Never disable Gatekeeper or System Integrity Protection. Do not remove quarantine or re-sign the app. If macOS reports malware, revoked authorization, or a damaged/modified app, do not override the warning: stop and contact support. Managed Macs may prohibit exceptions.

Connect your hardware

Enable Bluetooth and allow Stationary's Bluetooth permission. On Home, pair an FTMS-compatible bike/trainer or heart-rate sensor. Power-based workouts require power control. Heart-rate-guided workouts also require a heart-rate sensor. Devices that use other Bluetooth protocols are not automatically supported.

If scanning fails, check macOS Bluetooth permissions and whether another app is connected to the device. Do not change unrelated security settings. Start with a free ride and follow your machine's safety instructions.

Updates and backups

Updates are manual. Quit Stationary, download the new beta version, and replace the app in Applications. Stable bundle identity is intended to retain local settings and ride data; back up important data before updating.

Export important rides as CSV. Keep a normal Mac backup for app data and settings. Removing the app from Applications does not necessarily delete its local ride data or settings. See privacy and retention before removing files.

Report a problem

Open a GitHub issue with the app version, macOS version, Mac architecture, equipment model, and reproduction steps. Issues are public: do not post ride/heart-rate data, device identifiers, credentials, or unredacted logs.

You can also build from source. Website releases require neither .NET nor Xcode on the recipient's Mac.
