Math Symbols Input is a macOS input method for typing mathematical symbols with LaTeX-style commands. It works seamlessly with any Mac app.
The latest version is Version 1.3. To install or update Math Symbols Input:
- Download the installer for the latest version.
- Open the installer and continue through the installation steps.
- Log out and log back in (or reboot).
The installer can enable the input method automatically. If you want to configure input sources, see the macOS help page on input sources.
Type a backslash \ to start a command. The text should appear underlined while the command is being typed to show the input method is active. While the input method is active:
- Typing normally by pressing letters, symbols, or the backspace key will edit the command.
- Enter or tab will replace the command with its math symbol. If the command does not have an associated math symbol, the command text will be inserted verbatim instead.
- Space will replace the command and insert a space afterward.
- Backslash will replace the command and start a new command.
- Escape will insert the command text verbatim (e.g. if you need to type
\alphainstead ofα).

Yes, Math Symbols Input uses the last selected keyboard layout. Dead keys will continue to work, but the macOS's press-and-hold accent menu unfortunately will not.
Many programming languages are capable of inputting mathematical symbols, but this is usually limited to a single app. These include:
