macOS being a UNIX certified system means that you can install a lot more stuff with a lot fewer headaches than if you were on Windows.
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.

Cons
Con Expensive
OSX is tied Apple hardware and Apple hardware tends to be expensive for what it gives.
Con Limited hardware
Usually, the hardware that can run this can't be upgraded.
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 Closed source
Mac OS is closed source itself, which means that it is developed more slowly and has more problems.
Con No native package management
A comparison of package managers available for OSX can be found here.
Con Poor application support
Fewer apps run on Mac OS than on Windows or Linux.
Con Bash version is obsolete
macOS comes with an obsolete version of Bash, due to licensing issues.
Con Vendor-Lock-in
You are now forced to use the Apple services.
Con Silly modifier keys layout
The Command key is strange, Alt is where Super should be.
Con Poor X11 integration
The most open source software does work but is very poorly integrated due apples ancient version of the X-server.
