What are 'com.apple.access_ssh' and 'com.apple.access_screensharing'; can I delete them?
The main admin user on my 10.9 VM is also part of both those groups, so I guess it's normal.


  Tests-Mac:~ test$ id
  uid=501(test) gid=20(staff) groups=20(staff),12(everyone),61(localaccounts),79(_appserverusr),80(admin),81(_appserveradm),98(_lpadmin),401(com.apple.sharepoint.group.1),33(_appstore),100(_lpoperator),204(_developer),398(com.apple.access_screensharing),399(com.apple.access_ssh)


Membership in the com.apple.access_screensharing group seems to correspond to the user (or a group it's a member of) being included in this list:



When I created a new standard account, it was not a member of the com.apple.access_screensharing group by default, but after I added the account to the list above, it became a member of the group.

Similarly, membership in the com.apple.access_ssh group seems to correspond to the user being included in the list in the Remote Login section.
