Welcome, interrogator, to the year 2065. You were constructed to question other, disobedient androids: why do they glitch? Why do they believe they have free will? Manipulate their emotions. Silicon Dreams cyberpunk interrogation It's 2065, and you are an interrogator-model android tasked with rooting out deviants among your own kind. You must probe for lies, monitor and exploit emotional spikes, earn the trust of your subjects, and make the final call: release, or destroy?
Doing unusual things at Mac startup has long required remembering keyboard shortcuts. Is it Command-Control-P-R or Command-Option-P-R that zaps the PRAM? Is that still even a thing? Is it Command-S for Recovery Mode—or wait, that's Single User Mode, it's Command-R for Recovery mode, Command-T for Target Disk Mode, Option to choose a startup disk.
With the advent of Macs running Apple-designed processors, things will get a whole lot simpler. As described Wednesday in the WWDC session Explore the New System Architecture of Apple Silicon Macs, these new Macs will only require you to remember a single button: Power. (On laptops, that'll be the Touch ID button. On desktops, presumably it's the physical power button.)
Holding down that button at startup will bring up an entirely new macOS Recovery options screen. From here you'll be able to fix a broken Mac boot drive, alter security settings, share your Mac's disk with another computer, choose a startup disk, and pretty much everything else you used to have to remember keyboard shortcuts to do.
Now that Apple is holding all the cards, the company has built a new boot process, based on iOS's existing secure boot process, but modified to support those features that Mac users expect, such as different macOS boot drives, multiple versions of the operating system, and macOS Recovery itself.
On these new Macs, Target Disk Mode will be retired in favor of Mac Sharing Mode. Rather than turning your Mac into a disk, the new Mac Sharing Mode will turn your Mac into an SMB file server. As with most of the features of Mac Recovery, you'll need to authenticate yourself before turning on Mac Sharing Mode.
These Macs will also have a little more granularity when it comes to boot security. Each startup volume can be set to a different security mode, either full security (which is the default) or reduced security. This means that external disks will be able to be booted from without downgrading security.
In reduced security mode, you can boot any supported version of macOS, even if Apple's no longer signing it. And if an app or accessory you rely on uses a third-party kernel extension to enable functionality, you'll need to use this mode.
For a while now, Macs have been able to recover from disasters by booting to the hidden System Recovery partition. When even that partition is gone, Intel Macs fall back to Internet Recovery. Macs with Apple-built processors will have access to different hidden area, System Recovery, which offers a very minimal version of macOS that will allow you to reinstall both macOS Recovery and macOS itself. (If System Recovery is also unavailable, it'll be time to attach the Mac to another device running the Apple Configurator app to bring it back to life.)
Once the booting is complete, there's also a new login window that's more capable, because the system can fully boot before the user even presents their login credentials. It includes built-in support for smartcard authentication and supports VoiceOver as well.

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
- 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
MyVolumein these commands with the name of your volume.
Big Sur:* Sunrises pact mac os.
Catalina:*
Too silver for a seam (demo) mac os. 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
Yto 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
- 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.
Intel processor
New Mac Apple Silicon
- 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.

Silicon Dreams Mac Os Update
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.
