Reset `lsregister` in macOS for duplicate Open With apps

Well, first the obvious question - you don't have multiple copies of the respective apps installed, right?

I know there have been historical problems, especially with Microsoft-based apps, that b0rk the registry on updates, but it's been a while since I've seen this, so I thought it worth asking.

If you want to clear your application registry (and understand the pros and cons of doing so), you're right, -kill has been deprecated - but largely replaced with the -delete key instead, immediately followed by a reboot to initiate a rebuild.

Hi,

Previous versions of MacOS had the ability to reset lsregister via the follwoing command "./lsregister -kill -r -domain local -domain system -domain user". Current OS (Tahoe) will not allow that to run as -kill has been removed. How can I accomplish this functionality to be able to reset the "open with" menu as it contains many duplicate apps.
