macOS (previously Mac OS X and later OS X) is the current series of Unix-based graphical operating systems developed and marketed by Apple Inc. designed to run on Apple's Macintosh computers ("Macs"), having been preinstalled on all Macs since 2002. Within the market of desktop, laptop and home computers, and by web usage, it is the second most widely used desktop OS after Microsoft Windows.
SpecsUpdate
Pros
Pro Great combination of good GUI and powerful base
Based on FreeBSD with a Mach Kernel, it has a refined GUI user interface.
Pro Great multilingual support
Adding another keyboard layout is easy, even adding another input method for languages that can't be typed straight via keyboard input (Korean, Chinese, Japanese) is a few mouseclicks and works perfectly with all apps. Switching system (and thus app) language is a few mouselicks, too.
Pro Easy access to lots of great dev tools
There's a large selection of great development tools available for OSX. The operating system itself comes bundled with a powerful terminal emulator, called Terminal. Additionally, Apple provides tools, like Xcode, an IDE that contains a comprehensive collection of tools for developing OSX and iOS software, for free.
Pro Streamlined workflow between devices
Because this is an Apple product, there is a streamlined workflow between your computer and all mobile devices. For example, if you type an a Pages document, once you save, you can open the updated document just moments later on your iPad, and vice versa. The same goes for iMessage, (yes, you can text people with your phone number from your computer. Actually, you can text other people with apple devices with just your Apple ID, with or without a phone number, for free!) Numbers, Notes, Reminders, Contacts, and just about any other Apple workflow application.
Pro Polished UI
The UI of Mac OS is rather unrivaled. The smooth, responsive, and cohesive UI makes the system quite joyous to use.
Cons
Con Not user-friendly
MacOS's UI is complex and very difficult to get used to compared to something like Windows. Experience is required to use something like this and not something you could just easily use. Because of this, navigating is tricky. Even for some company like Apple, it's pointless when you want something you already know. Compared to iOS the experience required is too much.
Con Most software is closed source
For people who like to use open source tools for their development work, this may be a problem. There's plenty of advantages to open source software, one of which is the ability to tinker with and customize the tools themselves that you are using. Although there's plenty of FOSS tools available for Mac, especially through Homebrew, the number of packages available is much lower than the number of packages available for any Linux distribution.
Con Can delete anything on your device that they don't like
Ripped M4Vs from DVDs can disappear from your library of movies.
Con Default software updates require Apple ID
All but macOS and iTunes updates appear to require an Apple ID.
Con Finder hides items
To view hidden files and folders in Finder, e.g. ".ssh" for your keys, one must run "defaults write com.apple.finder AppleShowAllFiles YES;" in the Terminal, hold Alt while right clicking the Finder icon, and select "Relaunch". To hide them again, do the same with "NO" instead of "YES". If you wish to see folder display settings in ".DS_Store" files, Finder hides those anyway, so use another program.
Con Lacks color
System desktop preferences GUI offers blue and gray as button colors. The only other visible color options are that for text selections and the desktop background. A far cry from Windows, which lets you change task bar and window border colors, and many GNU/Linux GUIs can even change their widget shapes with a single click.
Con Confusing window management
Instead of a simple taskbar like on Windows, MacOS has many different and lacking window management features. Third party apps like Spectacle, HyperSwitch, and HyperDock are needed to gain similar functionality. Not being able to minimize an app by clicking the dock icon and not knowing at a glance which window the menu bar is referring to are still annoying.
