Download Tutor – Mac calculator & converter for Keynote 09
When you work with Apple’s Keynote 09 for presentations, the need for quick calculations, unit conversions, and on‑the‑fly data manipulation can become a hidden bottleneck. Noteboom Productions Ltd. answered that call with Tutor, a full‑version Mac‑only utility that slots neatly into the Business & Productivity suite under Calculators & Converters. Even though the download numbers are modest, the tool’s precision, ease of use, and seamless integration with Keynote make it a worthwhile addition for anyone who values accuracy and speed during a live demo or while polishing a slide deck. In this review we’ll walk through what Tutor offers, how to get it up and running, which macOS versions it supports, and whether its strengths outweigh its limitations.
Overview and Core Features
Tutor for Keynote 09 is a dedicated calculator and conversion engine built specifically for macOS environments that still run Keynote 09. Unlike generic calculators that sit on the desktop, Tutor lives inside the Keynote workflow, allowing presenters to invoke calculations without breaking the visual flow of a presentation. The software is currently at version 1.6, with its last update released on 1 April 2017. It is available in English and is distributed as a full‑version, single‑purchase package, meaning you won’t encounter trial restrictions or nagging upgrade prompts after installation.
- Integrated Keynote Toolbar Button: Launches the calculator directly from the Keynote interface, keeping your hands on the keyboard and eyes on the screen.
- Advanced Mathematical Functions: Supports basic arithmetic, trigonometric functions, logarithms, and exponentials, covering most presentation‑level calculations.
- Unit Conversion Library: Includes currency, length, weight, temperature, and data‑size converters, all up‑to‑date as of the 2017 release.
- Custom Formula Builder: Allows users to save frequently used expressions for instant recall during a slide show.
- Clipboard Sync: Results can be copied automatically to the macOS clipboard, enabling quick pasting into Keynote text boxes or tables.
- Dark Mode Compatibility: Matches macOS’s appearance settings, ensuring the calculator does not clash with your presentation theme.
- Secure Stand‑Alone Executable: No background services or internet connections are required, making it safe for corporate environments with strict IT policies.
The feature set may look compact compared with multi‑platform calculator suites, but the tight coupling with Keynote is the true differentiator. Users can perform on‑the‑fly calculations while delivering a talk, eliminating the need to switch to a separate app, jot down numbers, or risk a missed slide transition.
Installation, Usage & Compatibility
Getting Tutor onto your Mac is straightforward, even for users who are not comfortable with terminal commands. After purchasing, you receive a signed .dmg file. Open the disk image, drag the Tutor icon into the Applications folder, and macOS will prompt you to confirm that the app is from an identified developer. Because Tutor is a full‑version product, there are no activation keys or online verification steps, which reduces potential points of failure during installation.
Once installed, launch Tutor from the Applications folder. The first time you run the app, macOS may request permission to access the Accessibility API; this is necessary for the toolbar integration with Keynote. Granting permission is a one‑time action. After that, open Keynote 09, and you will notice a new “Tutor” button on the toolbar. Clicking the button opens a compact floating window where you can type expressions, select conversion types, and view results instantly.
Tutor is compatible with macOS X (10.4 Tiger) and later versions up to macOS 10.12 Sierra, covering the majority of machines that still run Keynote 09. While the software has not been officially updated for macOS Catalina or newer, many users report that it continues to function under Rosetta 2 on Apple Silicon Macs, provided that the underlying system libraries remain intact.
For optimal performance, ensure that your system has at least 200 MB of free disk space (the install package itself is under 50 MB). No additional runtime dependencies are required, and the app does not consume significant memory—typical usage stays below 30 MB, even when the custom formula library is populated. Updating the software is as simple as downloading the newer .dmg from Noteboom’s website and replacing the existing bundle in the Applications folder.

FAQ
Is Tutor compatible with the latest macOS versions (Big Sur, Monterey, Ventura)?
Officially, Tutor supports macOS X up to 10.12 Sierra. Some users have reported successful operation under Rosetta 2 on Apple Silicon Macs running newer OS releases, but this is not guaranteed. If you run a recent macOS version, consider testing the app in a non‑critical environment before relying on it for a live presentation.
Do I need an internet connection to use Tutor?
No. Tutor is a fully offline tool. All calculations and conversions are performed locally, making it safe for secure corporate networks and environments with restricted internet access.
Can I import or export my custom formulas?
Tutor allows you to save custom formulas within the app, but there is no built‑in import/export feature. You can manually copy formulas from the app’s text fields and paste them into a document for backup purposes.
What is the licensing model for Tutor?
Tutor is sold as a one‑time purchase with a perpetual license. Once you have downloaded the .dmg file and installed the app, you can use it indefinitely on any compatible Mac without additional fees.
Is there a free trial or demo version available?
No. Noteboom Productions provides only the full version of Tutor. However, the modest price point and the fact that the installer is a signed, safe package make it a low‑risk investment for most users.
