Pros
Pro Polished UI
The UI of Mac OS is rather unrivaled. The smooth, responsive, and cohesive UI makes the system quite joyous to use.
Pro Based on Unix
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.
Pro Powerful terminal
It's very similar to a Linux terminal.
Pro Best support for Objective-C
Pro More commercial software and gaming support compared to other Unix systems
Adobe CC, MS Office, Steam games.
Pro Has many special tools for developers
Has support for multiple IDEs.
Pro Lots of open-source software available
Because it's Unix under the fancy GUI, most open source ports easily to it.
Pro Ideal setup, out of the box
Next to no custom configuration is necessary.
Pro Great Git GUI tools
Tower, Kaleidoscope, SourceTree.
Pro Has software that only runs on Mac
For example, Sketch.
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 Great modifier key layout
Pro Using VMware you can also run Windows 10 on the Mac
This is useful for testing and some development tools that are Windows-only (XML Spy, MapForce).
Pro You need it to compile macOS or iOS apps
Pro Good overall system quality and performance
Lean, fast and surprisingly stable.
Pro Great hardware support
Pro No restrictive handholding, pure control over everything
The user can do whatever he wishes because the distro IS Arch - with and easy installer and great themes.
Pro Fast and simple package management
There can only be one Package Manager (pacman) ;)
Pro Easy installer
Pro Great for low performance hardware
Easy on the specs and still blazingly fast.
Pro Lightweight
Pro Arch Linux Wiki
Being an "easy to install version of Arch" means it is exactly easy to use the famous Arch Wiki!
Pro As slim as you want it
Based on Arch, Endevour OS keeps its core repositories slim and free of unnecessary dependencies. The distro comes with no bloatware, only the necessary packages. The repositories are nearly as full as those of Ubuntu, while they are often more up to date.
Pro AUR support
One of the best reasons to use an Arch based distro.
You can find almost every package there is in the Linux world!
Pro Stripped down to the bone
Since its stripped down, it is fast and you don't have to deal with bloatware.
Pro Great XFCE implementation
Their use of themes and configuration look great!
Pro Not based on Ubuntu
Pro Cutting edge rolling release
Exactly as Arch - allows users to stay on the most up-to-date versions of the software they are using.
Pro Support for a large variety of new hardware
Rolling release means newer, up to date, mesa and kernel versions able to handle newer hardware with better performance!
Pro Helpful community
Great team of developers and excellent forum support on their official website.
Pro Great community
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.

Con Very few options for running hosted, on the cloud
Con Too little customization options
Con Touchbar on Macbook Pro's
Con Not very user-friendly
Con NET installer on the way
Con Not for everyone
Con Kalu needs a little refinement
I applaud the developers to carry on the legacy of Antergos, the only niggling thing that I would appreciate is, while it's nice to see news about updates; my opinion is that once you dismiss the notifications they STAY dismissed. And just clicking on the icon brings kalu brings it to the foreground. Or have the functionality of turning off the news altogether would be well received. Good distro.
Con Same Cons that apply for Arch Linux
Since it is based on Arch, it is harder to install and can easily break.
Con Uses systemd
