Misdirection?
Just bought my Maverick os v.10.9.4 and many Manuals and Googled instructions leave me puzzled.
It may be because I have just switched over from Microsoft, but I used MACs continuously from1983 t0 1996 so I understand the Apple mind. However I must admit, things are still a struggle at the moment.
I too, was struggling withe the instruction to drag an app into something called an accounts section of the Apple preferences folder. What I got from that folder was a Window full of Icons, none of which specifically referred to something just labelled, Accounts, But I did seed 'User and Groups'.
You have to open that to get to another window and another choice in its toolbar.
Then you see a window with options for passwords and log in items which is where I found what I wanted.
SO....the proper answer at the beginning of this question should be:-
a) What is your System Version
b) Choose system !0.9.4 or whatever? Then:-
c) Apple Icon/System Preferences/Users & Groups/Log in Items
d)Drag Application Icon into the fame and check that it is added to the list.
I know that this is very fussy to all competent users but us beginners need that sort of detail. We are all idiots at this stage.
I used to describe Microsoft as an endless game of trivial pursuit with Bill Gates and, at the moment Apple has the same problems.
But it is a lovely machine.
