Computer is great so far guys, thanks for all the help. Ive been playing around for a bit, personally don't want to even install windows, but see how the wife likes it. I am confused about one thing though. Installing and download apps. When i download a instgalltion file, i believe .dmg ?... once i install the file, where does the program go? where is it installed? I couldnt find anything on the forums on this, could you guys maybe forward me to a link? thanks in advance
It depends on what you did.
If you... say... download Firefox... it places the .dmg in your Downloads Folder.
When you open the .dmg file... you'll see the Firefox Icon... and an arrow pointing to an alias to your Application Folder. At this point do NOT just double click Firefox. It is STILL only in the .dmg folder. (Imagine the .dmg to be like a CD you inserted in your computer... while you CAN run the apps from this 'cd' they are NOT installed).
To install it... you simply drag the Firefox icon... (following where the arrow is pointing) to the alias of your Application folder.
A little progress window should appear... showing you that your computer is actually moving/installing a file. (On the MBA it will only take a few seconds).
After THAT... you're Firefox (or whatever other app it is) is installed.
If you did everything correctly... you should find it by clicking on the Finder symbol (Dock at the bottom... first icon on the left). The window that opens should look vaguely familiar and similar to the windows explorer/my computer.
On the left hand side you see some favorites/shortcuts. One should read "Applications". Click it. It takes you right to the folder where ALL your Application reside.
If Firefox is there... you're good. If it's not... you may not have dragged the Icon from the .dmg onto the folder.
Also note:
Most applications on OS X you download from the internet are installed like this. Drag and drop from .dmg to Applications folder.
These then are only represented by their respective icons in the Applications Folder. (Unlike in Windows... where even Firefox has is OWN folder... with multiple files in it... and an Firefox.exe to launch the browser... here it is JUST the Application Icon itself)
BIG Suites like MS Office or Adobe CS... on the other hand use installers just like windows... nothing new here.
Apps from the App Store... are installed like on the iPhone or iPad. You hit install in the App Store after purchasing it... and it places them automatically in your Applications Folder.
To delete an App... simply drag it from the Applications Folder... onto the Trashcan in your Dock (rightmost Icon).
I hope that helped... rather than complicated the matter
