Dear @Marine Depuiset,
Welcome to Microsoft Q&A Forum!
I'm truly sorry to hear about the loss of your laptop. That’s a difficult situation, and I hope you're doing okay amidst the disruption.
Regarding your current MacBook Pro (2017) running macOS Ventura 13.7.8, I’ve looked into the compatibility and installation options for Microsoft Office 365, and here’s what you need to know:
Office 365 is compatible with macOS Ventura. However:
- The September 2025 update (version 16.101) is the final version that supports Ventura.
- Future updates and security patches will require macOS Sonoma or later.

Also, I have tried to research deeply in order to help you, but your MacBook Pro (2017) is not included in Apple’s official list of devices compatible with macOS Sonoma. According to macOS Sonoma compatibility: The Macs that run macOS 14 | Macworld, Apple has dropped support for several 2017 models, and only the iMac Pro (2017) remains eligible for Sonoma.

Attempting to upgrade using unofficial methods is not recommended, as it may lead to:
- System instability
- Security vulnerabilities
- Loss of hardware functionality
- No support from Apple

Besides that, you can still install and use Office 365 on Ventura by following these steps:
- Visit https://www.office.com
- Sign in with your Microsoft account linked to your subscription.
- Click “Install Office” to download the installer.
- Open the downloaded .pkg file and follow the installation prompts.
- Enter your Mac’s admin password when prompted.
- Once installed, sign in again to activate Office.

Finally, I would like to advise that you can continue using Office 365 on Ventura with version 16.101. If you need access to future updates or features, you may want to consider upgrading your device in the future to have security improvements. Microsoft may eventually stop offering support for older versions, making it harder to get help if issues arise.
I hope this information can help you in this case. Wish you all the best!
