Since installing macOS Sequoia (15.0), I've had a problem when I open a Microsoft Word, Excel and PowerPoint file with Office 365 (latest version 16.89). The application doesn't respond. I have to force it to quit and open again: MS Word opened the file correctly. I've reinstalled Office several times, but the problem persists. In general, I can open one file, then application not responding.
Mac Studio, macOS 14.7
This worked for me: Open the Terminal and run the following commands:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user
sudo /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -seed -lint -r -f -v -dump -domain local -domain system -domain user -domain network
killall Dock
Other than contacting Microsoft, I have no solution for you.
I have Office 2021 for Mac Home and Business installed on Sequoia v15.0 and all of the 16.89.1 applications work just fine.
I am running macOS Sequoia on Mac Studio and Microsoft 365 ver 16.89, no problem opening word & excel files.
Tengo el mismo problema. Lo que he estado haciendo es trabajar en línea el office, las aplicaciones del office en mi Mac se quedan trabadas y tengo que forzar el cierre.
Same problem here. Very frustrating
so frustrating, I´m working on office web , Microsoft don´t care about it , please let us know when a solution arrives
they don´t care about it, they send you to clean the cache, that doesn't work, is so frustrating this issue, this is my fifth day with the problem, and nobody resolves
You're very lucky. At the moment, I use a PC (windows 11) when I use Office 365
This works for me 1 time. Afterwards I have the same issue again. Do I have to downgrade from Sequoia?
I have just updated to Sequoia 15.1 and logged into Microsoft 365 Business Premium via Safari and everything is back working as it used to be under MacOS 14.
Adobe creative cloud also doesn’t work. This make my Mac not usable for my work, the whole creative cloud suite and MS office all dead. My only option is to change to a windows machine for now.
Thanks Firefly3301. Removing the FontCache fixed it for me :-)
Macos Sequoia 15.0 and office 365 - not responding
