Installing and Uninstall Apps
- Typically apps are installed in two ways, through the App Store or through some downloaded thing
- For App Store: Just click download and it'll be installed (apps found in the Applications folder, find that folder by opening the application called Finder...looks like a cartoon face cut in half)
- For downloaded: Apps will probably come as a .dmg file. To install double click the file (it's basically a zip file) and drag the application into the Applications folder (most apps give you the shortcut). If it has an installer than just do that.
- Downloaded .dmg files will remain on your desktop looking like a hard-drive icon until you drag to the trash. Once an app is in your applications folder, you can delete the .dmg file without worry
- Apps can be uninstalled largely by dragging the app file found in the applications folder literally into the trash can
- If you want to delete EVERYTHING associated with that app, you'll need to download an app like App Cleaner or some equivalent which will search every folder for various files associated with the app and delete those
Finder ("My Computer" for Mac)
- Finder will allow you to navigate to any file or folder that you're looking for
- The top level location is the literal hard-drive, but most of the common folders you'll want to access are your downloads and applications
- Hold the Command Button and press the space bar to invoke spotlight search, which will allow you to literally locate anything on your computer that you want
- Right click on something (or two finger click on your Macbook Air trackpad) and selecting "Get Info" will be your friend if you ever want to look at file metadata or change default applications easier
The Dock
- The dock serves as both a shortcut bar and an "active application" bar.
- If an application is dragged to the dock, it'll act as a shortcut going forward
- If an application is open, it'll have a little tick mark under the app icon to let you know it's still open (even if it's not visible)
- If an application isn't on your dock, it'll open up at the right most location of the dock and disappear when you close the application
- To FULLY CLOSE an application, press Command+Q. You'll know you did it when the docked application no longer has that tick mark to show it's open, or disappears entirely if it's not on your dock
- Pressing the red "x" in applications just closes the visual window, and doesn't close the literal application (that's what Command+Q does)
System Preferences ("Control Panel" for Mac)
The system preference section allows you to change settings like sound devices, iCloud items, network settings, users....etc etc.
If you're trying to adjust something about the OS or the computer itself you're likely going to land in System Preferences to do it
Disk Utility (find it using CMD+Space and typing it in...in fact find literally everything this way, it's fastest)
If you're ever looking to partition a drive, format a drive, erase a drive...this is your baby
Task Manager ("Ctrl+Alt+Del" for Mac...CMD+Space to find it)
If you're trying to see open applications and their resource utilization, or force close a misbehaving app, this is where you want to go
...
This should give a pretty good starting point, but let me know if there's anything else you'd want to know!
