MacOS15 / Sequoia - problems with Microsoft files

Hi,


I updated to Sequoia and everything seemed fine.


Now, neither my MacBook Pro (M3) nor my Apple Mini (M2) recognises Microsoft files any longer (Word. PowerPoint, Excel....).


Finder tries to open MS Word files with Preview. When I tell Finder to open the file with MS Word I get the following error message: "Apple could not verify "xxxxxxxxx.docx" is free of malware that may harm your Mac or compromise your privacy". Other file types work perfectly well as before.


Everything works well on my iOS 18 devices.


Anyone else having this problem. Any ideas?


Cheers

SWE

The workaround that worked for me, go to the file with *.docx extension and "right click" to select "Get Info".

From the "Get Info" screen, go to where it says "Open With:", make sure you select "Microsoft Word" and then select "Change All...". This will associate all "*.docx" files back to "Microsoft Word", and no more issues when clicking from the Finder window.


Similarly, do the same for *.xlsx extensions and Microsoft Excel.


Hope this helps everyone. Apple and MS still need to provide an update that fixes this by default on the next update.
