Need Sierra gone

[ALW1026]

I have a 2014 MBP. I have so many Sierra compatibility issues I need to roll it back. Problem is I never made a backup of my computer. How do I roll it back? Is there a way to do it without having to repurchase office?

may use a keyfinder?

I used produkey in windows, not available for mac.

must be something to locate key.
If bought digitally did they not email you the key?

Your options are very limited with no backup.
My only recommendation, with the limited information provided, is Internet Recovery. Here is information about it:

Some key items to be aware of with Internet Recovery are:
1. You need to backup your system before performing internet recovery. I would recommend a clone to an external drive using Carbon Copy Cloner instead of Time Machine, as suggested in the article.
2. Internet recovery will install the OS that shipped with your MBP. That will be Mavericks (10.9.5) for a 2014 MBP.
3. You will have to check to see if your installed apps will work with 10.9.5.
4. If you want Yosemite or El Capitan OS then you will need get them and install from the Mac App Store under the Purchased tab. They are no longer available from Apple if you have not previously purchased them.

You will not need to repurchase Office.
