5. End of Support Status

Microsoft ended mainstream support for Office 2016 for Mac on October 13, 2020, and extended support ended on September 12, 2023. This means:

No more security updates or bug fixes.
Compatibility with newer macOS versions (Ventura, Sonoma, Sequoia) is not guaranteed.
Using this installer today is not recommended for systems connected to the internet, as unpatched vulnerabilities may exist.

The installer says “This package is incompatible with this version of macOS.”

You likely have macOS 10.15 (Catalina) or newer. Office 2016 requires the 32‑bit to 64‑bit transition. The final compatible version is macOS 10.14 Mojave.

First Launch & Activation

Open any app (e.g., Word). A dialog box will appear saying "Microsoft Office needs your permission to access the keychain" – click Allow.
Sign in with your Microsoft account (the one linked to your Office 2016 product key) or enter the 25-character product key manually.
Activation is automatic. If successful, no nagging toolbars or limited functionality will appear.

4. Technical Execution Details

When executed, this .pkg file typically performs the following actions:

Prompts for Permission: Requests an administrator username and password.
Writes Files: Installs the suite applications into the /Applications/ folder.
Installs Frameworks: Places shared frameworks and fonts into the /Library/ folder.
Launch Daemons: May install background processes for licensing and update checks.

3. Security Assessment

If you are analyzing this file, consider the following potential risks:

Legacy Code: The code inside the package is outdated. Modern macOS versions (Ventura, Sonoma) may block the installer because it lacks the latest Apple notarization and security signatures required by modern Gatekeeper protocols.
Source Verification:
- Legitimate Source: If downloaded from a verified Microsoft server or an old Volume Licensing Service Center, the file is likely safe but outdated.
- Pirated/Malicious Source: If this file was downloaded from a torrent site, "warez" forum, or unofficial software repository, it carries a HIGH RISK. macOS .pkg installers are a common vector for malware (such as the Shlayer trojan) because they require administrative privileges (root access) to run.
Integrity Check: Without a valid SHA-1/SHA-256 hash from Microsoft, it is impossible to verify if the file has been tampered with.

8. Modern Alternatives

Given the age and lack of security updates, consider:

Microsoft 365 (Office 365) – Subscription, fully supported, runs natively on Apple Silicon.
Office 2021 or 2024 for Mac – One-time purchase, supported until at least 2026/2028.
LibreOffice or Apple iWork – Free, modern, secure alternatives.
