Edge/IE run some underlying services for built-in windows features, so uninstalling them can cause issues with completely different parts of the OS.
Ran into an issue with a client still running Office 2016 where uninstalling IE11 prevented them from opening any links within those apps. Office was harcoded to look at IE for link handling and didn’t respect the setting for your default browser.
Yup. Our RMM tools work best on Windows machines. Honestly, Linux is fine too, but MacOS is the worst to manage.
If anything needs to be modified/deployed on MacOS, I have to create a new PPPC and deploy it through Intune/Jamf/Addigy, otherwise you can guarantee the end user won’t accept the correct security prompts and things won’t work.
