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.
"the sound" that I think he wants to suppress is the startup chime, which can't be turned off because it serves a very specific hardware debugging purpose related to the boot process. There are hacks that can turn down the volume of the chime but it cannot be completely turned off.
But you have to mute the computer before you shut it down. Remembering to perform an action every single time in order to prevent a startup chime is sub-optimal. Having an option to turn it off would be better than relying on a 3rd party hack.
switched to linux long time ago. keep OSX bc of ease for some things, but have more than one computer for this reason. definitely a tradeoff but one i sure found worthy. never did figure out the sound issue.
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.
