Hi Allen 🙂
Okay, so I went through all the info you gave me, and i have a few questions if you wouldn’t mind (please forgive me if this seems like a long reply!):
Where the article says:
—If “Only these users” is selected on the other Mac, make sure the login name you’re using is on the list of allowed users. : by this do they mean in the system pref’s sharing window under "Users"? or somewhere else? (because i dont see anywhere saying specifically “Only these users”; Nor is there a list there entitled "allowed users.")
—Using an Apple ID: why wouldn’t this way work too?
—In some cases you need the network area or workgroup for the shared computer.: i am the computers’ owner, so where would i look for this info if needed? Or, would it simply pop up in a scroll-down list if it was necessary?
—2. When you locate the shared computer or server, double-click it, then click Connect As. : Well, after i open it on my iMac, it automatically shows "Connected as: (my home folder login name) ". I have already a day or two ago added this main username as my one "favorite server" in the scroll-down under the Go/ Connect to Server pop-up.
Also:
—i have my macbook’s home folder listed in the sys pref’s shared folders list, and in its users list i have my home folder account name listed. (By the way, i have my account name and full name the same exact name, so i hopefully avoid confusing myself. I only want to use this home folder account in general. Any other user i set up is for my own testing purposes anyway. So i only have this name listed under the "favorite server" list.)
And yet!—
even though i have this user allowed "read & write" access, and i am connected on my iMac as this user, i cannot ………………………………………………………………….
—Is it secure to tell you what my account name is here? It would just make things easier to keep clarified, if so!
—is is good enough to simply have my ENTIRE Users folder in my home shared folder’s users allowed list, on both my macs? That would make things way simpler for me! (then i would just keep my users lists set to "everyone"="no access", and have no other users listed there except my home folder’s= "read&write".)
—(related Q to above) I am assuming that when i right-click a shared folder in the sys prefs list and that "Apply permissions to Enclosed Items" pops up and i click on it, then click ok, it means that all the folders and files inside it will be allowing access to those users listed?
—(a side question: Is it possible that sometimes, if i change any settings such as Full Name or user allowance prefs, it might not take effect right away (eg., until i have logged out then back in or something)? )
—Here is one example of a folder i cannot open on my iMac because it says:
--oops that was screenshot--

On my macbook, i have the shared folder User set to "read&write" for my current (home folder) name.
Also, in this User folder’s "get info", i do have my current name set to "read&write" as well.
When i click "show in finder" on my macbook, this User folder shows up in my macbook’s HD folder.
I see this same User folder in my iMac’s HD’s Users folder, in the same subfolder:
/Users/laptop-user/Public/Drop Box.
On my macbook, to be extra sure i also checked that "shared folder" box in its Get Info.
Also, on my iMac, in the laptop-user’s "get info", i have my main account with "read&write", and the shared checkbox checked.
To make sure it wasn’t just Dropbox, i just added a picture to the laptop-user’s Pictures folder from the macbook side. Then double checked all its Get Info for permissions. Then tried to open that folder from iMac— no luck!
What could i be missing? What else can i do?
