Since creating a screenshot is no great challenge in OS XCommand-Shift-3 will do the trickwhy turn to a third-party program like Snagit Because the application smoothly handles a number of tasks, including grabbing just one window, a portion of the screen, or a single menu as well as annotating screen images.You grab the handles of a resizable window to select all or a portion of the screen.You can add text, arrows, bubbles, and color fill; you can even blur out a section (if it contains an image or some text you dont want to share).
In macOS Mojave or earlier, open iTunes, choose iTunes Preferences from the menu bar, then click Advanced.When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically.Each file stays right where you last saved it, and downloads when you open it.
