Microsoft ended mainstream support for Office 2016 for Mac on October 13, 2020 . While the software still functions, it no longer receives security or feature updates.

Open any app (e.g., Word) and check About Word to ensure the version starts with "16.16".

If you need help with across multiple Macs or need the specific serializer file , I can provide instructions on how to access them through the Microsoft Volume Licensing Service Center (VLSC) .

Volume License (VL) versions use a VL Serializer for activation rather than an Office 365 login.

Minimum macOS 10.10 (Yosemite) or later. It is officially supported on macOS Sierra (10.12) through macOS Mojave (10.14).

Obtain the Office 2016 for Mac installer package (approx. 1.7 GB).
