I'm new to mac and my first one (an iMac) should be coming pretty soon. I was wondering what I should know about macs and the OS before I get it. Anything would be helpful. Also I was reading in another thread about trial software already on the machine? Is this going to be on my new iMac?
There are so many things to consider, and so many little nuances that you will only see with first hand experience over a good amount of time. At some point, like most of us switchers, you'll have that "now i get it" moment; and you won't consider switching back.
If I were to pick out one tip, albeit a small one; get used to new key-commands. I am big into using the keyboard over the mouse but had to learn a new language (so-to-speak) when moving to OS X. First is finger placement for things like (windows) Cmd-X, C, and V for cut, copy and paste. While they're the same (mac) Command/Apple-X, C, and V, now I use the command key with my thumb, rather than the typical windows keyboard placement with my pinky-finger.
Also, get used to using Command-O (rather than Enter) to open, Cmd-I rather than Alt-Enter (get info/properties) and CMD-[ and CMD-] for forward and back as opposed to the Cmd-Arrows.
There's also a nice selection of open source software selections for OS X, most of which you'll find in the windows world too. Theres also some VERY good shareware apps in the $10 to $30 range. AppZapper, Disco, Transmit, and TextMate are some that I've plonked down cash for.
Finally, the advice I give to anyone wanting to make the switch - Give yourself a task to do. Make a photo gallery, write out something you've been meaning to write. Import some video or even lay down some tracks in Garage Band. It's just as important to know you have the ability to do some of the things you bought a mac for, just as much as it is important knowing you could at some point; And completing a project from start to finish is simply the proof that you can, and did, and "gee, wasn't that fun and easy?"
Good Luck and welcome to a brighter world! -AB
