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.
What you need to create a bootable installer
I have actually tried Bootcamping my mac, but bootcamp is up to spec on OS sierra yet, I've tried virtualbox but that doesn't really support the 3d engine very well, and I've tried Wine but it consistently has legacy issues with Freetype going back for years; all to try and engage with the PC games market. Officially, the operating system that was available on that Mac at the time that you bought it is the oldest version of macOS that can run on that Mac. It's likely that an older OS won't include.
- A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB of available storage
- A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan
Download macOS
- Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. 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. - Download: OS X El Capitan
This downloads as a disk image named InstallMacOSX.dmg. 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.
- 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 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.
Beerylife mac os. Big Sur:*
Catalina:*
Mojave:*
High Sierra:*
El Capitan:
* If your Mac is using macOS Sierra or earlier, include the --applicationpath
argument and installer path, similar to the way this is done in the command for El Capitan.
After typing the command:
- Press Return to enter 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 volume is erased. - After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
- When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.
Use the bootable installer
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Apple silicon
Damned Inconvenient Mac Os Catalina
- Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
- Turn on your Mac and continue to hold the power button until you see the startup options window, which shows your bootable volumes.
- Select the volume containing the bootable installer, then click Continue.
- When the macOS installer opens, follow the onscreen instructions.
Damned Inconvenient Mac Os 11
Intel processor
- Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
- Press and hold the Option (Alt) ⌥ key immediately after turning on or restarting your Mac.
- Release the Option key when you see a dark screen showing your bootable volumes.
- Select the volume containing the bootable installer. Then click the up arrow or press Return.
If you can't start up from the bootable installer, make sure that the External Boot setting in Startup Security Utility is set to allow booting from external media. - Choose your language, if prompted.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

A bootable installer doesn't download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model. No bud mac os.

command and the arguments you can use with it, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:
Earlier this year, the Lighthouse for the Blind and Visually Impaired of San Francisco (known as San Francisco Lighthouse to people who speak standard English) agreed that the support for the Macintosh Terminal app using VoiceOver was an inadequate solution for all but the most minimal of its possible use cases. To remedy this issue, they funded the development of a new little screen reader called tdsr.
Tyler Spivey, author of tdsr, had attempted to port the really old UNIX command line screen reader yasr to Macintosh but as yasr is a rat's nest of old C code, it proved easier to scrap it and write a new command line screen reader from scratch in Python.
While it's been rumored that tdsr stands for 'Tyler's Damned Screen Reader,' it does not. In fact, tdsr stands for 'Two Day Screen Reader' as Tyler got its first functioning prototype up and running in only two days. A lot more work has gone into tdsr since and users of the bash shell (the one used in Macintosh Terminal but not supported well with VoiceOver) will recognize all of the keystrokes as will users of GNU emacs or emacspeak. I personally use tdsr to maintain my server and when I'm messing around with the little bit of Python programming I try to do.
The importance of tdsr is that a command line is still essential for blind people who write software, study computer science and/or maintain servers and do IT stuff. For years, NVDA on Windows has been the only screen reader to provide truly useful support for a command line (JAWS used to do it well but it's deteriorated over the years). Thus, most blind programmers, hackers, IT professionals and CS students have had to use Windows or GNU/Linux for their work. With the advent of tdsr, a student assigned a Macintosh can now enjoy the same functionality as their peers using Windows.
We want to get the tdsr story out to as many people in our community as possible. To that end, we hope that readers of this post will help to raise awareness of tdsr and its potential value to professionals, students and hobbyists alike. So, if you have the means and opportunity, please direct people to this post or write articles of your own. Of particular interest and value will be stories of how you are implementing tdsr in your own workflow and projects.
You can check out tdsr on Tyler's GitHub page() for it. You can download the software (instructions on the GitHub page), install it and, as it comes from our little crew, you get the source code to inspect, learn from, modify or do whatever you like with it short of including it in a piece of proprietary software. While Tyler has written most of it, we've received some code contributions from outsiders and one fellow added braille support, something Tyler hadn't planned on doing himself.
If you've questions about tdsr, feel free to send an email to 3 Mouse Technology and we'll try to get you an answer as quickly as possible. If you are interested in using a command line effectively on OSX, please do check out the software, post comments here and if you find a bug, please report it on the GitHub system to ensure Tyler will see it. If you're a Python programmer and would like to participate in the future of tdsr, you can get the code from GitHub and Tyler will consider all push requests.
