When comparing macOS vs PsychOS, the Slant community recommends PsychOS for most people. In the question“What is the best laptop OS?” PsychOS is ranked 11th while macOS is ranked 25th. The most important reason people chose PsychOS is:
PsychOS is designed for older/lighter, 32-bit, i686 hardware with plans to go even further back with i486 (PsychOS486), i386 and older (PsychDOS), and so on and so forth as opposed to always trying to run on the latest hardware, not that it could in most cases anyway since 32-bit i686 operating systems will run on most x86_64 ones.
Specs
Ranked in these QuestionsQuestion Ranking
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 Runs well on older, 32-bit hardware (i686)
PsychOS is designed for older/lighter, 32-bit, i686 hardware with plans to go even further back with i486 (PsychOS486), i386 and older (PsychDOS), and so on and so forth as opposed to always trying to run on the latest hardware, not that it could in most cases anyway since 32-bit i686 operating systems will run on most x86_64 ones.
Pro RetroGrab is really cool
It lets you install old software for use with emulators like DOSBox but run them as if they were normal programs from the normal applications menu.
Pro No fuss. Just works.
A lot of the programs are already set up for you. Just boot it and go. This is definitely one of the better SHTF distro's.
Pro QuickEdit
There's a yad-based tool you do not see on any other GNU/Linux distro in which you can simply right-click pretty much any file and then use the "QuickEdit" option to quickly edit small things about a file such as size if it's an image or video, convert the file, or even render the file if it's a Blender project. It's nice not having to open an image with GIMP every time I want to resize or convert something.
Pro The IceWM option looks and functions nice
Most GNU/Linux distributions that include IceWM as a desktop environment option don't do too much to it, if a t all. PsychOS seems to have a customized or themed version that actually doesn't feel you with dread and still uses many of the keyboard shortcuts from XFCE.
Pro Lots of command-line tools
Lots of command-line tools and I really like the CLIMax thing. It's a good tool to have if you want to spend time in the command-line but aren't that experienced. Also, it plays a quick, one-time ascii animation when you go into the tty for the first time.
Pro TONS of Thunar Custom Actions
PsychOS comes with a lot of Thunar Custom Actions, many of which as disabled, but they are there none the less; most probably just in case. Right-click on a DOOM WAD shows there's a menu item to play it directly using LZDoom.
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 Bloated
Over 3000 packages by default including several package managers.
Con 7 package managers included
There should only be one.
