Open up your favorite Web browser and go to Google Image Search, then type in some words that describe the kind of images you seek. For the images to look their best, IвЂ™ll need to find images that match this resolution. You can see my screen is set to 1680 x 1050. Easiest is to go to System Preferences -> Display and just look at the default setting: Next you need to figure out your current screen resolution. You can create a folder вЂ“ in case you havenвЂ™t figured it out yet вЂ“ by choosing вЂњNew FolderвЂќ from the вЂњFileвЂќ menu: I use the name Desktop Images to make things clear and easy. LetвЂ™s start by going to the вЂњPIcturesвЂќ folder and creating a new folder for the desktop images. Oh, lots of people call these screen-size images wallpaper too. When weвЂ™re done, weвЂ™ll simply point the Desktop & Screen Saver system preference on your iMac to use the images in the new folder instead. To summarize before we start (I know you methodical NASA types!) weвЂ™re going to create a new folder for the images, do a Google image search to find photos that are the exact size of your screen, then save them, one-by-one, into the folder. If you own an M1 Mac on the latest 11.3 RC, I recommend taking it for a test drive.Really interesting question, actually, because itвЂ™s spurred me to think about the most efficient way to accomplish what you seek and to realize that while itвЂ™s easy, there are a bunch of steps involved to accomplish what you seek. вЂњHelloвЂќ is a great addition to M1 Macs, and will complement the redesigned iMac, with its variety of colors, particularly well. Doing so will cause darker versions of the screen saver to display when dark mode is enabled on your Mac. If youвЂ™d like the Hello screen saver to match the system appearance in terms of light or dark mode, simply leave the match system appearance option enabled.

Show вЂњhelloвЂќ in all languagesД«y default, the hello greeting is displayed in various languages, such as Japanese, Croatian, and Spanish, but users have the option of unchecking the Show вЂњhelloвЂќ in all languages option so that the screen saver is only displayed in English.

If youвЂ™re looking for additional variety, Apple also includes an вЂњAllвЂќ selection that randomly displays selections from all theme types. Lastly, there is the Minimal theme, a decidedly monochromatic take that I imagine will look just as good on the silver M1 iMac as it does the space gray MacBook Pro. As its name implies, Soft Tones is a softer, more pastel-like theme, which features colored text for less contrast. The вЂњhelloвЂќ text on the Spectrum theme is always white, providing a nice contrast between the background color and foreground text. Colors consists of similar colors that youвЂ™ll see on the new iMac, including orange, blue, yellow, and pink. The default Spectrum theme is the one that provides the most visual pop, as it consists of white text on a bright colored background. Hello features three distinct themes: Soft Tones, Spectrum, and Minimal. LetвЂ™s briefly break down what each option allows. The Hello screen saver includes three different options: Theme, Languages, and Match System Appearance. WhatвЂ™s really cool is that the screen saver features several configurable options to adjust the look.

Select the Hello screen saver, and click preview to see a preview of it in action.
