Hi Guys, just to let you know that the final version of Office does not work properly and have 70-100% CPU issue as reported on numerous posts here. In my case, it's the WORD with which I have the issue with and no remedies posted here help. Please provide the fix as soon as possible, because this bug renders the new suite useless...

Hi,

To resolve this issue, is your installation of Office for Mac fully updated?

In any Office application go to the Help menu and choose Check for Updates to launch the Auto Update app. Let AutoUpdate install the updates and then restart your Mac.

Update us with results for further assistance.

I'm having the same issue on the same software versions.

It's a large document ~130 pages with a lot of tables. Typing and scrolling are both laggy and I'm frequently getting SBBOD when I change a style (e.g. set a highlighted section of text to bold takes ~5 secs).

CPU usage is <1% when Word is in the background, but bring it to the front and CPU is >50%. It jumps to 80-110% when typing or making changes.

I have the latest Word for Windows in a VM with a fraction of the resources allocated and am not seeing the same issues with this document. 

Changing to Draft view has sped up scrolling and improved typing lag somewhat, but the high CPU usage remains.

UPDATE: updating to the latest fast preview (15.31 161227) has fixed the lagginess, but still experiencing 40-50% CPU when typing. At least it's now usable.

    I have the same problem:

    OS X 10.11.4

    MacBook Pro Retina Mid 2012

    MS Word 15.21

    CPU Usage is at least 50% or more - when any document is opened or created. Even if Word is totally idle (window in the background - covered with other active windows or minimized to the dock)... If the windows is minimized, the load goes down to few % after around a minute, but when I maximize the window again load increases to > 50% immediately and remains at this level.

    My batter is in poor condition, and this makes my laptop totally non-portable...

    Please fix.

    If any more information is needed let me know. I'm willing to help to investigate the problem.

    Still having this problem with up-to-date Word (15.19.1) and OSX (10.11.4).

    CPU usage around 100% immediately after creating a blank document.

    Battery usage is 50-60...

    Mac is getting hot, fans are speeding up.
