FYI my old operating system was MacOS Mohave 32-bit technology. Because I recently had my hard drive replaced on my MId 2013 MacBook Air and a new 64-bit MacOS Big Sur operating system installed at the same time as the repair, my current MS Office apps won't launch and I am directed to upgrade which means download and subscribe, which I don't have a problem doing, the newer version of MS Office365 that will run on the 64-bit technology. Recently installed MacOS BigSur (64-bit app) and currently have Microsoft Office365 app what worked on old MacOS Mohave(32-bit) but now those Microsoft app icons have the prohibitory symbol over them and I'm directed to upgrade. Office Home & Business 2019: This stand alone includes Outlook. The current Office for Mac Office 365 or Office 2019 (One-time purchase) are OK with Catalina/Big Sur Microsoft 365 and Office 2019 support for Apple Silicon Apple Silicon compatibility in Office 2016 is questionable. If you have Office 2011 for Mac or before WILL NOT run, For Catalina Office 2016 for Mac needs to be v15.35 or later.īig Sur-Microsoft recently announced that it was officially ending support for Office 2016 for Mac on October 13, 2020. The App Store apps will require you to subscribe to Microsoft 365 Unless you buy from Microsoft: To activate a Microsoft Office 365 subscription you simply enter the email address you used when you extended the subscription with Microsoft. Please help!! I need to use the microsoft word, powerpoint, and excel daily. I really do not want to spend money on buying another microsoft office package. My question is why isn't my old subscription compatible with big sur. From the app store I can open microsoft word however it says 'subscription required to edit and save, start your one month free trial of Microsoft 365 or sign it to activate an existing subscription.' When I go to app store to update them, its shows microsoft 365 all ready purchased. After updating to big sur my microsoft office icons all have a white x across them and when I try opening them it says I need to update them.
