Thanks, all. I figured this out. The problem was that, first, I am new to the Mac environment, and second, I was entering the wrong "connect As" name under "Shared."
The problem now, though, is that after shutting down, I lose the connection to my MacBook Air and have to re-enter all the information again. Is that normal, or did I miss a setting that causes both my iMac and MacBook Air to remember their connection settings? Thanks again.
A normal situation.
STEP 1. In the Connect to Server field, where you enter the credentials, check the box:
Remember this password in my keychain
That takes care of not entering info every time.
STEP 2. Next, you can also have the share mount every time automatically. A couple ways to do this, i ncluding adding the shared volume in the
Log Options list in the user account (in System Preferences).
What I prefer is simply a shortcut (alias) to the shared volume in the dock or Finder sidebar.
I prefer it because if you setup automatic mounting....it will try to mount every time you log in. If you are off your network, if the other Mac is not visible (turned off, etc.) you will get an error every time it try and fails.
I would rather click on the shortcut and have it mount in 2-3 seconds when I want it, rather than nag me every time it fails.
Also easy: Browse the network, select the Mac (has to be running, and on the network). It should be a single click to connect once you check the box per step 1.
