Hello OLIVEIRA A,
I’m Segunfunmi, an Independent Advisor and Microsoft user like you. Thanks for posting the query here in this forum.
Hello, I’m sorry to hear that you’re having trouble installing Microsoft Teams on your iMac. Here are a few steps you can try:
Check Privacy Settings: In your System Settings, check the Privacy Settings. In the Files and Folders category, the Installer app needs to have access to the Downloads folder or else you can get an error when trying to install.
Quit Teams: If Teams is still running, right-click the Teams icon in the dock, and then select Quit, or press Command (⌘)-Q.
Clear Cache: Enter the following command in Terminal: rm -r ~/Library/Application\ Support/Microsoft/Teams. Then, restart Teams.
Reinstall System: If the problem persists, boot into the Recovery volume and reinstall the system.
Check Compatibility: Check if your Mac is compatible with MacOS Ventura.
Create New User: Create a new user with admin permission on mac and try installing the Teams app.
Please let me know if these steps help or if you need further assistance.
Kind regards, Segunfunmi.
