A Happy Mac is the normal bootup (startup) icon of an Apple Macintosh computer running older versions of the Mac operating system.It was designed by Susan Kare in the 1980s, drawing inspiration from the design of the Compact Macintosh series and from the Batman character Two-Face. Mac OS, operating system (OS) developed by the American computer company Apple Inc. The OS was introduced in 1984 to run the company's Macintosh line of personal computers (PCs). The Macintosh heralded the era of graphical user interface (GUI) systems, and it inspired Microsoft Corporation to develop its own GUI, the Windows OS.
These key combinations apply only to Mac computers with an Intel processor, not Mac computers with Apple silicon.
Come to find out literally everything is incompatible with my OS, and I can't even update the OS. I've tried finding old versions of GameMaker, but all of it is just gibberish I don't understand that still won't run on my OS. The only thing I've been able to use is Twine, which doesn't even make applications. Game Dev Tycoon is a strategy and management game that, following the lead of Game Dev Story (available on iOS and Android), lets you create you own video game development company, taking it from your basement to the pinnacle of the world of electronic entertainment. Your adventure actually does begin in the basement of your character's house. I have been convinced that Mac OS X presents a superior (for my uses) desktop system. Does anyone else use Mac OS X for game development or graphics software development and which development environments do they use? Thank you for your time.
To use any of these key combinations, press and hold the keys immediately after pressing the power button to turn on your Mac, or after your Mac begins to restart. Keep holding until the described behavior occurs.
- Command (⌘)-R: Start up from the built-in macOS Recovery system. Or use Option-Command-R or Shift-Option-Command-R to start up from macOS Recovery over the Internet. macOS Recovery installs different versions of macOS, depending on the key combination you use while starting up. If your Mac is using a firmware password, you're prompted to enter the password.
- Option (⌥) or Alt: Start up to Startup Manager, which allows you to choose other available startup disks or volumes. If your Mac is using a firmware password, you're prompted to enter the password.
- Option-Command-P-R:Reset NVRAM or PRAM. If your Mac is using a firmware password, it ignores this key combination or starts up from macOS Recovery.
- Shift (⇧): Start up in safe mode. Disabled when using a firmware password.
- D: Start up to the Apple Diagnostics utility. Or use Option-Dto start up to this utility over the Internet. Disabled when using a firmware password.
- N: Start up from a NetBoot server, if your Mac supports network startup volumes. To use the default boot image on the server, hold down Option-N instead. Disabled when using a firmware password.
- Command-S: Start up in single-user mode. Disabled in macOS Mojave or later, or when using a firmware password.
- T: Start up in target disk mode. Disabled when using a firmware password.
- Command-V: Start up in verbose mode. Disabled when using a firmware password.
- Eject (⏏) or F12 or mouse button or trackpad button: Eject removable media, such as an optical disc. Disabled when using a firmware password.
If a key combination doesn't work
If a key combination doesn't work at startup, one of these solutions might help:
- Press and hold all keys in the combination together, not one at a time.
- Shut down your Mac. Then press the power button to turn on your Mac. Then press and hold the keys as your Mac starts up.
- Wait a few seconds before pressing the keys, to give your Mac more time to recognize the keyboard as it starts up. Some keyboards have a light that flashes briefly at startup, indicating that the keyboard is recognized and ready for use.
- If you're using a wireless keyboard, plug it into your Mac, if possible. Or use your built-in keyboard or a wired keyboard. If you're using a keyboard made for a PC, such as a keyboard with a Windows logo, try a keyboard made for Mac.
- If you're using Boot Camp to start up from Microsoft Windows, set Startup Disk preferences to start up from macOS instead. Then shut down or restart and try again.

Remember that some key combinations are disabled when your Mac is using a firmware password.

Mac OS X does not have a set of libraries like Microsoft's DirectX specifically for writing games. The lack of game-specific libraries can be difficult for people new to Mac game development because they don't know where to start. This article provides an overview of the technologies you need to learn to write Mac games.
Technology Paths
There are three technology paths you can take to write Mac OS X games. The first path is Cocoa, which is Apple's Objective C development framework. The second path is Carbon, which is Apple's C API for writing Mac applications. The third path is to use a game library like SDL or Allegro.
What path should you choose? The path to choose depends on whether you want your game to run only on Mac OS X or if you want your game to run on multiple operating systems. If you want your game to run on multiple operating systems, you should use a library like SDL or Allegro. Those libraries handle a lot of cross-platform issues for you so one set of code will run on Linux, Mac OS X, and Windows with minimal changes. I'm not familiar with Allegro, but I know SDL works well on multiple platforms. Learning SDL is going to be easier than learning multiple technologies to get cross-platform compatibility.
If you want to write a Mac-only game, you have a choice between the Cocoa and Carbon paths. One thing to keep in mind is that Cocoa and Carbon are frameworks for writing GUI applications. You're going to use a tiny portion of them in your games: creating a window to draw into, and running an event loop. Most of Apple's game technologies have a C interface, which means they consist of C functions. Both Cocoa and Carbon applications can call C functions so you can write games in both Cocoa and Carbon. Should you use Cocoa or Carbon?
Both Cocoa and Carbon are suitable for games so the path you choose depends on personal preference. One thing to consider is that on Mac OS X 10.5, you can write 64-bit Cocoa applications, but most of Carbon will not have 64-bit support. I can't imagine you needing to write a 64-bit game right now, but Cocoa's 64-bit support is an advantage. I would strongly recommend Cocoa for creating tools for your game, such as level editors. Cocoa is easier than Carbon for GUI programming.

One disadvantage of Cocoa for some people is it uses Objective C, which looks strange to C and C++ programmers. But you can mix Objective C and C++ code using Objective C++ so you can write most of your game in C++, writing only a small amount of code in Objective C.
