Prevent File Sharing access with Apple ID

apple-idNetworksharing

I use same Apple ID on different Macs (used by different people), only to use Find My Mac.

So I disabled Message, Facetime etc. – App Store updates are still a bit problematic since I don't want to share the account password.

We also use Drop boxes to share files, so everyone has enabled public file share of Public folder.
But since El Capitan (or Yosemite), all computers is accessible to everyone, because they connect themselves with the Apple ID (instead of connecting as Guests), and not only Public folder but also HD and Home folder are visible. (And I see the apple ID as "Connected with".)

How can I disable that?
And is there a better management of Apple IDs (I want to avoid a per-device ID)?

Thanks!

Joan, try this (it worked for me):

  • Log in as a different user than the one you want to modify; also, make sure the account you want to modify is not logged in.
  • Open the Users & Groups pane of System Preferences.
  • If the lock icon in the lower-left corner of the Users & Groups window is “locked,” click it and provide an administrative username and password when prompted. This allows you to make changes.
  • In the list of accounts on the left, right-click (or Control-click) on the name of the account you want to modify, and then choose Advanced Options from the resulting menu.
  • Look inside the box that says "Aliases". If your apple ID is listed there, delete it.
  • Then close the padlock, and that did it for me. If computers connect via the Apple ID now, all they can see are the shared, public folders. Nothing else.

Hope it works!
