Writing Assembly For Mac Os X
About Mac Scripting
Scripting allows you to automate complex, repetitive, and time-consuming tasks by writing scripts that interact with apps, processes, and the operating system. A script consists of a series of statements, each of which performs a specific operation. These statements work together to automate tasks. Through scripting, you can create powerful workflow solutions that enhance productivity, reduce errors, save time, and save money.

- If you're writing an OS for x86 PCs (the best choice, due to the huge amount of documentation available), you'll need to understand the basics of how a PC starts up. Fortunately, you don't need to dwell on complicated subjects such as graphics drivers and network protocols, as you'll be focusing on the essential parts first.
- MacOS is the operating system that powers every Mac. It lets you do things you simply can’t with other computers. That’s because it’s designed specifically for the hardware it runs on — and vice versa. MacOS comes with an entire suite of beautifully designed apps. It works hand in hand with iCloud to keep photos, documents, and other.
- Mar 05, 2014 I’ve been learning a little assembly with some other Hacker Schoolers. It’s fun, but I spent nearly an hour yesterday trying to find a modern online guide for running x86-64 assembly on OS X, and couldn’t really find anything that didn’t involve complicated uses of gcc.Frankly, without the ever-wise advice of davidad, I probably wouldn’t have figured it out, so here’s a quick guide.
There are many different scripting languages. On the Mac, the primary ones used for automation are AppleScript and JavaScript.
Note
OS X also includes Automator, an app for building workflows that run prebuilt, configurable actions to perform tasks in apps and throughout the operating system. Automator doesn’t require you to write any code, but can be extended through scripting. Because Automator uses preconceived actions and operates in a linear manner, it’s more limited in functionality than scripting. Automator is great for performing simple tasks involving a small number of sequential steps or apps. Scripting is a better choice for performing advanced, branching, or complex tasks.
Python and Perl are other examples of scripting languages.
AppleScript
AppleScript is a mature scripting language developed by Apple. It’s relatively easy to learn in relation to other scripting and programming languages, has been around since System 7.1, and has been widely adopted in both enterprise and personal workflows. While the AppleScript scripting language uses an English-like terminology which may appear simple, it is a rich, object-oriented language, capable of performing complicated programming tasks.
The core fundamentals of AppleScript are described in AppleScript Language Guide, as well as in numerous third-party books.
JavaScript
JavaScript is a popular cross-platform scripting language. Historically, it’s been most commonly used to implement features on websites and in web-based apps that are accessed through browsers. However, some apps implement JavaScript-based scripting models for the purpose of automation. In OS X 10.10, JavaScript became a peer to AppleScript in OS X. There are many third-party websites and books that document the JavaScript language.
For fundamentals on JavaScript as a scripting language for automation in OS X, see JavaScript for Automation Release Notes. For information about the JavaScript language, see Mozilla’s official JavaScript documentation.

These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.
Download macOS
Find the appropriate download link in the upgrade instructions for each macOS version:
macOS Catalina, macOS Mojave, ormacOS High Sierra
Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
OS X El Capitan
El Capitan downloads as a disk image. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.
Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace
MyVolume
in these commands with the name of your volume.
Catalina:*
Mojave:*
High Sierra:*
El Capitan: - Press Return after typing the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type
Y
to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created. - When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.
* If your Mac is using macOS Sierra or earlier, include the --applicationpath
argument, similar to the way this argument is used in the command for El Capitan.
Use the bootable installer
After creating the bootable installer, follow these steps to use it:
- Plug the bootable installer into a compatible Mac.
- Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it. - Choose your language, if prompted.
- A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.
