It is oh-so-tempting to just pull that flash drive out of your USB port when you’re done with it. But resist the urge! Unceremoniously disconnecting an external drive from your Mac can result in all sorts of problems—namely, you could inadvertently damage files on the drive. Do yourself—and your data—a favor and eject your disk the proper way. OS X provides a few methods for doing so—here are three of them.
Dragging the icon: This method of ejecting a disk has been around as long as the Mac itself. Click the disk icon on the desktop (assuming you have your Mac set to show disks on the desktop), then drag it to the Trash icon in the Dock—it’ll turn into an Eject symbol. Wait a few seconds for the disk to disappear from the desktop and remove your disk.
If you’re relatively new to the Mac, it may not be immediately obvious as to how you would delete an app—after all, OS X doesn’t come with any sort of uninstaller like Windows does. Removing apps from your Mac is usually a very easy process, however, though there are some caveats.
From the Finder
Open a Finder window and navigate to your Applications folder. It should be accessible via the Favorites sidebar by default; if it isn’t there, pop open Spotlight and do a search for “Applications folder” and it should pop right up.
Back in the early days of OS X, Apple’s desktop operating system shipped with an Internet preference pane that let you change, among other things, your default Web browser and email app. At some point, Apple decided to put these settings in Safari and Mail, respectively, but with OS X Yosemite and later, the option to change your default Web browser returned to its rightful home in System Preferences.
If you’d like to change your Mac’s default browser, open System Preferences (look in the Apple menu if you don’t know where to find it), then click General. Next, find the pop-up menu labelled “Default web browser:” Click it, then choose whichever browser you’d like to use as your default.
