Install

Tinycast needs macOS 26 or later, on Apple silicon or Intel.

Homebrew

This is the easiest route. Homebrew clears the macOS quarantine flag for you, so the app opens without a warning.

brew trust --tap abue-ammar/tinycast
brew install --cask abue-ammar/tinycast/tinycast

You run brew trust once. Homebrew will not install from a third-party tap until you trust it.

Intel Macs

macOS 26 Tahoe is the last release that runs on Intel, so the stable build ships in two sizes. The command above installs a smaller build for Apple silicon only. On an Intel Mac, install the universal cask instead:

brew install --cask abue-ammar/tinycast/tinycast-universal

You do not need to work out which one you need. tinycast refuses to install on Intel, and both casks give you the same Tinycast.app. The universal build also runs on Apple silicon; it is just a bigger download.

Channels

Each channel is a separate app with its own settings, permissions and login item. They run side by side, so you can keep stable and try a beta at the same time.

brew install --cask abue-ammar/tinycast/tinycast@beta

The beta does not share settings with stable. To move your setup across, use Backup. The two stable casks are the same app, so you can only have one of them installed.

Downloading directly

Builds are also on the Releases page.

Tinycast is self-signed. There is no paid Apple Developer ID behind it yet, so macOS quarantines a copy you download by hand and will not open it. After you drag the app to Applications, clear the flag once:

xattr -dr com.apple.quarantine "/Applications/Tinycast.app"

You do not need this if you installed with Homebrew.

Updating

Tinycast updates itself. Once a day it checks for a new release on its own channel. When one is out, a window shows what changed, and one click downloads it, installs it and relaunches. You can also check any time with Check for Updates in the launcher, the menu bar or Settings → About.

Because the app manages its own version, brew upgrade skips Tinycast on purpose. That is expected, not a bug. See Updates for the details.

Every release is signed with the same certificate, which is what keeps your Accessibility grant working across updates.

Uninstalling

brew uninstall --cask abue-ammar/tinycast/tinycast

To remove the files Tinycast made, delete its Application Support and Caches folders:

rm -rf ~/Library/Application\ Support/com.tinycast.app
rm -rf ~/Library/Caches/com.tinycast.app

That Application Support folder holds your snippets, notes, quicklinks, clipboard history and AI chats, so copy out anything you want to keep first. The beta uses com.tinycast.app.beta instead.

API keys you saved for AI or MCP servers, and extension sign-ins, live in your login Keychain. Remove them in Keychain Access if you want them gone too.

To remove a different app and everything it left behind, Tinycast has a built-in uninstaller.
