How to remove obsolete contact groups? So with Mojave, Apple removed particularly LinkedIn and Facebook internet accounts and as a result my macOs contacts app now have LinkedIn group with hundreds of my LinkedIn contacts which I do not want to have in contacts app and I can't delete it.



Any way to remove LinkedIn group? (as well as Facebook group)
For account groups, you need to remove or disable in the preferences. In the "Contacts" app, go to the menu bar, "Contacts" then "Accounts..." those accounts should be listed. If so, you can remove or turn them off (uncheck the "Enable this account" box) there.
