Apple shortened the name to "OS X" in 2011 and then changed it to "macOS" in 2016 to align with the branding of Apple's other operating systems, iOS, watchOS, and tvOS. Apple's other operating systems ( iOS, iPadOS, watchOS, tvOS, audioOS) are derivatives of macOS.Ī prominent part of macOS's original brand identity was the use of Roman numeral X, pronounced "ten" as in Mac OS X and also the iPhone X, as well as code naming each release after species of big cats, or places within California. All releases from Mac OS X 10.5 Leopard and after are UNIX 03 certified, with an exception for Mac OS X 10.7 Lion. The first desktop version, Mac OS X 10.0, was released on March 24, 2001. During this time, Apple co-founder Steve Jobs had left Apple and started another company, NeXT, developing the NeXTSTEP platform that would later be acquired by Apple to form the basis of macOS. MacOS succeeded the classic Mac OS, a Macintosh operating system from 1984 to 2001. Within the market of desktop and laptop computers, it is the second most widely used desktop OS, after Microsoft Windows and ahead of Linux (including ChromeOS). It is the primary operating system for Apple's Mac computers. It can be purchased and downloaded online.MacOS ( / ˌ m æ k oʊ ˈ ɛ s/ previously OS X and originally Mac OS X) is an operating system developed and marketed by Apple Inc. ![]() If your Mac doesn't meet those specs, the previous version of CleanMyMac will work fine.ĬleanMyMac 2 is an excellent and powerful utility that I have found safe and effective to use. The app requires OS X 10.7.5 or greater and 50 MB of free disk space. Other configurations are available at similar savings. As a special incentive, CleanMyMac 2 is $19.95 for new users through March 8 for a single Mac license. MacKeeper has some similar functionality at the same price, but it is a bundle of 16 apps. I've found many of these paid utilities are in the $80 to $100 dollar range, while CleanMyMac 2 is $39.95. There are many utilities around to maintain and clean a Mac. Obviously, CleanMyMac 2 has gotten smarter about finding junk. On my 1 TB hard drive version 2 still found 1.5 gigs of things to get rid of. I tried the latest version after a quick run of the older version. The company also provides a trial version which allows you to remove up to 500 MB of stuff for free. I have used the original for quite some time, and I expected the latest version to have an upgrade cost. The app can also uninstall apps no longer being used, and hunt for unused extensions and control panels. CleanMyMac 2 has also applied a fresh and more direct GUI making some of the more complex operations simpler. The app also removes old logs and caches, and can take a significant whack at your iPhoto library by deleting master copies of previously edited photos. The app now has an auto-cleanup function that looks for non-needed files and cleans them up, not by simply deleting them, perish the thought, but by asking you first. CleanMyMac 2 has just arrived, and it is even more powerful than previous versions. CleanMyMac has been a powerful tool for Mac maintenance for a long time. ![]()
