I found there were many things that I did not know, and had to learn.
How do I rename a file in the GUI? (right click, select "get info", change the file name in the box, etc.)
How do I do keyboard text navigation? Option (or alt)left or right arrow will move one word. Command left or right arrow will move to the beginning or end of a line. Adding shift will select the text. (etc etc.)
How do I turn off the sound when I turn my machine on? (Don't turn the machine off, or use a third party software.)
There's some things which can't be done.
But, in the end, computers are tools, and people need to be comfortable with their tools. So use whatever fits your needs.
you can just press the Return key to rename a file.
I thought it would 'do an action' (launch or open). I do need to learn more.
"How do I turn off the sound when I turn my machine on?" Mute the computer before shutting it down.
Not allowing the user to add this functionality (even if it's a hidden option in a config file somewhere) is sub optimal in my opinion.
There are some great things about OSX but there are a few small but frustrating things too.
