The time has come, where our favourite tech leaders evolve. Microsoft is ending support for Windows 10 and Apple is also gearing up for major changes in its macOS lineup. With macOS Tahoe 26 soon to be released this autumn, macOS Ventura (version 13) is now approaching its end of life. Therefore, businesses need to reconsider and start exploring upgrade options soon to remain secure.
Last updated: 18th September 2025
When will macOS Ventura (version 13) support end?
Apple released macOS Tahoe (version 26) on 15th September 2025, which means macOS Ventura (version 13) is now outside Apple’s standard support window. While Apple has not officially confirmed the exact end-of-support date, it is widely expected that Ventura will stop receiving security updates and support by 30th November 2025.
Apple typically supports the three most recent macOS versions, and with Tahoe now joining Sonoma (14) and Sequoia (15), Ventura has effectively entered its final phase of life.
What happens after the deadline?
From 30th November 2025, the following changes are expected for macOS Ventura:
- No longer receive free security update releases
- No longer receive technical support from Apple
- No longer receive bug fix patches
- May see a decline in performance
- May see App compatibility issues
Without ongoing updates, devices running Ventura will become more vulnerable to cyber threats, potentially putting business, staff, and customer data at risk. This can also lead to compliance issues and operational instability.
Industries with high Mac usage such as education, research, and retail, may face particular challenges, especially where seamless integration across systems and locations is essential. Unsupported software can disrupt workflows, reduce productivity, and impact service delivery.
Considerations for upgrading to a newer MacOS
While Ventura can still be used for now, doing so beyond November 2025 poses significant risks, especially for businesses. We strongly recommend upgrading to a supported version like macOS Sonoma (14) or the newly released macOS Tahoe (26) to maintain security, compatibility and compliance. You can check for updates via System Settings > Software Update.
However, there are a few things to consider before planning your upgrade:
- Hardware compatibility: Apple typically supports Mac devices for about 7 years from their release date. After that, older hardware may no longer meet the technical requirements for newer macOS versions. For example, devices purchased in 2018 or earlier may be unable to upgrade beyond macOS Ventura due to compatibility constraints. For businesses, we recommend conducting an audit of all Mac devices across the network. Identifying machines that are aging or unsupported allows teams to plan timely replacements and ensure systems remain secure, compliant, and compatible with modern software tools.
- Application and workflow compatibility: For businesses using a variety of applications and workflows, it’s important to allow for a testing period to ensure compatibility. This also includes compatibility with the CRM as well as plugins.
- Security and compliance: Using outdated versions of macOS can introduce serious risks, from security vulnerabilities to compliance issues affecting both individual users and the broader organisation. It’s vital to ensure all devices are running a macOS version that aligns with your business’s cybersecurity policies and any applicable industry regulations. We recommend upgrading to the latest macOS version compatible with each device to maintain optimal protection and performance. Users can check for updates by navigating to System Settings > Software Update. If no update appears, the device may not support newer versions, at which point a hardware refresh should be considered.
What’s new in macOS Tahoe?
Released on 15th September 2025, macOS Tahoe (version 26) introduces a refreshed design and powerful new features aimed at improving productivity, security, and cross-device integration.
One of the standout changes is the new Liquid Glass look, which makes the interface feel smoother, clearer and more modern. It’s built to run especially well on newer Macs and includes tools to help with everyday tasks.
These changes might affect how some apps work or how people use their Macs day to day, so it’s a good idea to start preparing. That means checking if your Mac can run Tahoe, testing important apps to make sure they still work, and helping your team get used to the new layout and features.
If you’re still using macOS Ventura, now is the time to plan your upgrade to ensure your Mac remains secure, compliant, and fully functional.
Don’t let ageing technology hold you back
If you’re still using devices running outdated versions of macOS, now is the time to upgrade. We recommend keeping systems within Apple’s recommended three-year benchmark to ensure optimal performance, security, and compatibility. For machines older than 7 years, replacing the device may be more cost-effective than upgrading.
