Personalizing the several features on a Mac computer can be a brilliant way to spice things up to your taste. The desktop background, user icons, lock screen wallpaper can be modified in such a way that when you are logged into your Mac, you will instantly know it is yours.
This is key, especially if you are surrounded by those that use Mac computers that are very similar to yours. Below is how to go about it:
How Can I Change The Lock Screen On A Mac Computer?
Let's assume that you already have a picture in mind, and it is formatted as a PNG file, below is how to get this done:
- Access your image using Preview - if this is not your default viewer, just right-click the picture and choose "Open with" and then "Preview."
- Have the picture renamed as "com.apple.desktop.admin" by double-tapping the name at the top of the Preview window.
- Access the Finder in the dock way down on your screen.
- In the top toolbar, choose "Go" and then "Go to Folder."

- Drag your picture onto the image or folder labelled "com.apple.desktop.admin.png" and tap "Replace."
Your fresh lock screen image will be visible when next you get yourself logged into your Mac after a restart or shut down. Bear in mind that if you modify your desktop background in future, your lock screen image will be replaced with a blurred version of your desktop.
More Information On A Mac
The Macintosh is a family of personal computers designed, manufactured and sold by Apple Inc. since January 1984.
The original Macintosh was the first mass-market personal computer that featured a graphical user interface, built-in screen and mouse. (Although the Sinclair QL became available one month before the Macintosh family and thus was technically the first home computer with a graphical user interface, the QL never attained widespread commercial success.) Apple sold the Macintosh alongside its popular Apple II family of computers for almost ten years before they were discontinued in 1993.
Early Macintosh models were expensive, hindering its competitiveness in a market dominated by the Commodore 64 for consumers, as well as the IBM Personal Computer and its accompanying clone market for businesses. Macintosh systems found success in education and desktop publishing and kept Apple as the second-largest PC manufacturer for the next decade. In the early 1990s, Apple introduced the Macintosh LC II and Color Classic which were price-competitive with Wintel machines at the time. However, the introduction of Windows 3.1 and Intel's Pentium processor which beat the Motorola 68040 in most benchmarks gradually took market share from Apple, and by the end of 1994 Apple was relegated to third place as Compaq became the top PC manufacturer. Even after the transition to the superior PowerPC-based Power Macintosh line in the mid-1990s, the falling prices of commodity PC components, poor inventory management with the Macintosh Performa, and the release of Windows 95 saw the Macintosh user base decline.
Prompted by the returning Steve Jobs' belief that the Macintosh line had become too complex, Apple consolidated nearly twenty models in mid-1997 (including models made for specific regions) down to four in mid-1999: The Power Macintosh G3, iMac, 14.1" PowerBook G3, and 12" iBook. All four products were critically and commercially successful due to their high performance, competitive prices and aesthetic designs, and helped return Apple to profitability. Around this time, Apple phased out the Macintosh name in favor of "Mac", a nickname that had been in common use since the development of the first model. Since their transition to Intel processors in 2006, the complete lineup is Intel based. Its current lineup includes four desktops (the all-in-one iMac and iMac Pro, and the desktop Mac Mini and Mac Pro), and two laptops (the MacBook Air and MacBook Pro). Its Xserve server was discontinued in 2011 in favor of the Mac Mini and Mac Pro.
Apple has also developed a series of Macintosh operating systems. The first versions initially had no name but came to be known as the "Macintosh System Software" in 1988, "Mac OS" in 1997 with the release of Mac OS 7.6, and retrospectively called "Classic Mac OS". In 2001, Apple released Mac OS X, a modern Unix-based operating system which was later rebranded to simply OS X in 2012, and then macOS in 2016. The current version is macOS Mojave, released on September 24, 2018. Intel-based Macs are capable of running non-Apple operating systems such as Linux, OpenBSD, and Microsoft Windows with the aid of Boot Camp or third-party software. Apple also produced a Unix-based operating system for the Macintosh called A/UX from 1988 to 1995, which closely resembled contemporary versions of the Macintosh system software. Apple does not license macOS for use on non-Apple computers, however System 7 was licensed to various companies through Apple's Macintosh clone program from 1995 to 1997. Only one company, UMAX Technologies was legally licensed to ship clones running Mac OS 8. Since Apple's transition to Intel processors, there is a sizeable community around the world that specialises in hacking macOS to run on non-Apple computers, which are called "Hackintoshes".
