Open Office for MacBook

[Jill Melanie Wirth]

Hello ~ I have used Open Office 3.4.1 on my Mac OS X version 10.6.8
I just bought a new Mac OS Sierra, version 10.12.5
I would like to download Open Office on this computer.
Please tell me what version to choose.
Thank you very much for your help.
All the Best,
Jill Wirth
