Is Your Microsoft To Do App at Risk? The Ultimate Guide to the Devastating August 2025 Update
If you use the Microsoft To Do app on your iPhone or Mac, there is an important change coming that you need to know about. Starting in late August 2025, Microsoft will stop providing updates for its To Do app on older Apple operating systems. This decision is a necessary step to ensure the app remains secure and performs at its best for everyone.
This change helps Microsoft focus on providing the best experience on newer, more secure technology. While your app won’t stop working overnight, failing to update could expose you to frustrating problems down the line.
Understanding the Change
Between late August and mid-September 2025, Microsoft will officially end support for the To Do app on devices running iOS 16 and macOS 12. After this period, to receive any new updates for the Microsoft To Do app, your devices will need to have at least iOS 17 or macOS 13 installed.
Your app will still be there, but it will be frozen in time. You will not get any new features, performance improvements, or, most importantly, security patches. Over time, as technology moves forward, an unsupported app can become unreliable and unsafe.
Why This Matters for You
Continuing to use an older version of the To Do app might not seem like a big deal at first, but it comes with significant risks. Without regular updates, you miss out on three key benefits:
Security
This is the most critical issue. Security updates patch vulnerabilities that could otherwise be exploited by attackers. Without them, your personal and professional information within the app could become vulnerable.
Performance
Software companies constantly release updates to fix bugs and make their apps run faster and more smoothly. Users on older versions will not receive these fixes, which could lead to slower performance or crashes.
New Features
Microsoft is always improving its apps by adding new tools and capabilities to help you be more productive. If you don’t update, you won’t have access to any of these new features.
What You Need to Do to Prepare
To avoid any disruption and keep your task lists safe, it is important to take action. The steps are straightforward and will ensure you continue to get the most out of the Microsoft To Do app. To ensure a smooth transition and continued access to updates and support, here is what you can do:
- Check Your Current OS: First, find out which operating system your device is running.
- On your iPhone (iOS): Go to Settings > General > About. Your iOS version will be listed there.
- On your Mac (macOS): Click the Apple menu in the corner of your screen and select “About This Mac.” The version number will be displayed.
- Update Your Device: If you are running iOS 16 or macOS 12 (or anything older), you should update your device to iOS 17 or macOS 13, or a newer version if available. Upgrading your operating system is the best way to continue receiving app updates for Microsoft To Do and to protect your device with the latest security features from Apple.
- Communicate with Your Team: If you use Microsoft To Do for work, it’s a good idea to let your organization’s IT department know about this change. They may need to review device management policies to ensure compatibility with the newer operating systems.
If your device is too old to update to a supported operating system, you can still use the web version of Microsoft To Do. It is accessible from any web browser and is always up to date. While the installed app will continue to function, it’s not a secure long-term solution.
