For Office LTSC 2016, 2019, 2021 and 2024 on a Mac. No product key to type in: the second part of the package activates Office.
Before you start
- There must be no other version of Microsoft Office left on the Mac. Steps 1 to 10 completely remove an existing version, including an expired Microsoft 365 trial.
- macOS in one of the three most recent major versions released by Apple, on Apple silicon (M1–M4) or Intel.
- About 10 GB of free space and an internet connection. Part 1 is around 2.8 GB.
- The administrator password of the Mac. The product key is not needed.
1 The three files
Everything you need is here. Part 1 is the normal Office package and comes straight from Microsoft: the same installer serves Microsoft 365, Office LTSC 2021 and Office LTSC 2024. Part 2 is the small serializer that registers your volume licence.
Unlock the downloads
The installation files are part of your licence. Enter your order number and the e-mail address you used for the purchase.
No order number to hand? Write to us and we will send it again.
Download all three files first. They land in the “Downloads” folder.

Frequently asked questions
Office asks me to sign in or to enter a key. What do I do?
That window belongs to Microsoft 365 and can be closed. Install Part 2: afterwards, under “About”, Office shows the activated volume licence.
Does it work on Apple silicon (M1 to M4)?
Yes. The package runs natively on Apple silicon and on older Intel Macs as well.
There are still traces of an old version. What helps?
Run the removal tool again, restart the Mac and start again from step 11. Otherwise just write to us from the contact page.
