Newbie Mac owner, got a few questions.

post #1 of 3
Thread Starter 
So, i just recently received my new MacBook Air. I wanted one so I can try my hand at iOS app development and just to try something new, so I bought the cheapest of the new MBAs to see how I liked them.

Needless to say, after having used nothing but Linux and Windows computers I have quite a few questions.

1. The storage thing under "About this Mac" says I'm using 15GB for "other". What is "other" and how do I see the which files it is, so I can decide if I should uninstall them or not?

2.How do I install apps to an external hard drive? Do I just drag the app over to it, and run it from there?

3. Follow up to #2; When I install apps to my external hard drive will they install any extra folders to my internal one, or is everything installed onto the external?

4. Any handy tips I need to know about Macs? Or, any helpful programs I should get?

Thanks all for the help.

Uh, you've got some pretty wide-open questions here. It's been a few years since Iv'e been on OS X, but I'll help you out as much as I can.

1. About this Mac typically shows how much HDD space the OS is using.
2. Installing apps. Yes, you can do it anywhere.
3. Some apps may create small hidden folders on your install directory to link back to the Library folder on your OS drive.
4. Lots!
-Disk Utility is your friend. it can burn, repair permissions, etc. Learn how to use it.
-Macs typically use .DMG files instead of .ISO.
-Pref files can often sort out a wacky app. Deleting a pref file and restarting the App can quite often fix whatever went wacky.
-Use Automator. it's quite useful for routine things you do.
DO NOT delete your Library folder. I had a lady who did that once. Dunno how, but she did... needed a complete OS reinstall.

So, the 15GB of "other" is just the OS? Also, I found out about #3 myself with Steam. Even after I installed Steam onto my external hard drive it still installed all the games onto my internal one.

Now, is there any program I can use that will delete unused files left over after having uninstalled Steam?

EDIT: Or maybe something like CCleaner but for Macs?
