Install PennyBolt

Get PennyBolt running on macOS, Windows, or Linux.

Last updated: April 16, 2026

Installing PennyBolt takes about a minute. Download the installer for your operating system from pennybolt.com/download , run it, and open the app. The rest of this page covers the details: what to download, how to verify it, what to do if your operating system warns you about us, and how to uninstall if you ever want to.

System requirements

PennyBolt runs on modern desktop hardware. If your computer can comfortably run a web browser and a spreadsheet, it can run PennyBolt.

  • macOS 12 (Monterey) or later. Apple silicon and Intel are both supported.
  • Windows 10 or 11. 64-bit only.
  • Linux — any mainstream distribution from the last three years. We ship an AppImage that runs without installation and a .deb for Debian and Ubuntu.
  • About 150 MB of disk space for the app. Your PennyBolt file is separate and starts small.
  • An internet connection for downloading the installer and for update checks. PennyBolt does not need to be online after install.

Download

Go to pennybolt.com/download and pick the build for your operating system. You’ll get one of:

  • macOS: PennyBolt-{version}.dmg
  • Windows: PennyBolt-{version}-setup.exe
  • Linux: PennyBolt-{version}.AppImage or pennybolt_{version}_amd64.deb

Every release page also lists a SHA-256 checksum. If you want to verify your download came through intact, see Verify your download below.

Install on macOS

Double-click the .dmg to mount it. Drag the PennyBolt icon to your Applications folder. Eject the disk image. Open PennyBolt from Applications or Spotlight.

The first time you open PennyBolt, macOS may show a warning that says something like:

“PennyBolt” can’t be opened because Apple cannot check it for malicious software.

This happens because PennyBolt is notarized by Apple but published by a small developer. To open it:

  1. Open System Settings → Privacy & Security.
  2. Scroll down to the Security section.
  3. You’ll see a line about PennyBolt being blocked. Click Open Anyway.
  4. Authenticate with your password or Touch ID.

You only need to do this the first time. After that, PennyBolt opens normally.

Install on Windows

Double-click the .exe installer. Windows SmartScreen may say:

Windows protected your PC

Click More info, then Run anyway. This warning appears because we’re a small publisher — SmartScreen’s trust signal is based on how many downloads it has seen. As more people install PennyBolt, the warning will stop appearing for new users.

Follow the installer’s prompts. The defaults are fine. PennyBolt installs to C:\Program Files\PennyBolt\ and adds a Start menu shortcut.

Install on Linux

Two paths.

AppImage (any distro): make the file executable and run it.

chmod +x PennyBolt-{version}.AppImage
./PennyBolt-{version}.AppImage

The AppImage is fully self-contained. It does not install anything — it just runs. To put PennyBolt in your application menu, use a tool like appimaged or integrate it manually.

.deb (Debian, Ubuntu, and derivatives):

sudo dpkg -i pennybolt_{version}_amd64.deb

This installs PennyBolt system-wide and adds a desktop entry.

Verify your download

Every release page lists a SHA-256 checksum next to the download. Verifying the checksum confirms the file you downloaded matches the file we published.

macOS / Linux:

shasum -a 256 PennyBolt-{version}.dmg

Windows (PowerShell):

Get-FileHash -Algorithm SHA256 .\PennyBolt-{version}-setup.exe

Compare the output to the checksum on the release page. If they match, your download is intact. If they don’t, download it again.

Uninstall

We don’t mind. Here’s how.

macOS: drag PennyBolt.app from Applications to the Trash. Empty the Trash.

Your PennyBolt file and any backups stay where you put them. If you want to remove PennyBolt’s application support folder too:

rm -rf ~/Library/Application\ Support/PennyBolt

Windows: Settings → Apps → Installed apps → PennyBolt → Uninstall.

Your PennyBolt file and backups are not removed. To remove PennyBolt’s local data:

Remove-Item -Recurse "$env:APPDATA\PennyBolt"

Linux (.deb):

sudo apt remove pennybolt

For the AppImage, just delete the file.
