You're A Big Guy Mac OS

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 14 GB 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 will be downloaded 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 will be downloaded 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 will install 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

Use the 'createinstallmedia' command in Terminal

1. Connect the USB flash drive or other volume that you're using for the bootable installer.
2. Open Terminal, which is in the Utilities folder of your Applications folder.
3. 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.

Big Sur:*

Catalina:*

Mojave:*

High Sierra:*

Big Guy Pizza

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:

1. Press Return to enter the command.
2. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
3. 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.
4. After the volume has been erased, you may see an alert stating that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
5. When Terminal says that it's been completed, 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

1. Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
2. Turn on your Mac and continue to hold the power button until you see the startup options window, which shows your bootable volumes and a gear icon labelled Options.
3. Select the volume containing the bootable installer, then click Continue.
4. When the macOS installer opens, follow the onscreen instructions.

Intel processor

1. Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
2. Press and hold the Option (Alt) ⌥ key immediately after turning on or restarting your Mac.
3. Release the Option key when you see a dark screen showing your bootable volumes.
4. 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 the External Boot setting in Startup Security Utility is set to allow booting from external media.
5. Choose your language, if prompted.
6. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

For more information about the createinstallmedia command and the arguments that you can use with it, make sure the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:

• Big Sur: /Applications/Install macOS Big Sur.app/Contents/Resources/createinstallmedia
• Catalina: /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia
• Mojave: /Applications/Install macOS Mojave.app/Contents/Resources/createinstallmedia
• High Sierra: /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia
• El Capitan: /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia

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.

Apple began phasing in the use of its SSD-friendly APFS file system with High Sierra for SSD-only Macs, and then upgraded Fusion Drive-based Macs in Mojave. In Big Sur, Time Machine volumes can finally be formatted with APFS, too. But in this transition, one capability was quietly lost: APFS volumes cannot be shared for network access via Apple's relatively ancient Apple Filing Protocol (AFP).

AFP dates to the pre-OS X days, with a version appearing in System 6 in the late 1980s. As with most older protocols, it got long in the tooth, and Apple went from just supporting the Windows and Linux world's SMB to shifting to it as the only built-in sharing method. Way back in OS X 10.9 Mavericks, Apple began moving away from AFP in favor of the industry-standard SMB, although it still hasn't removed support.

In Big Sur, Apple dropped the ability to share volumes via AFP entirely, but even though Catalina retained AFP-sharing support, as noted above, APFS-formatted volumes could not be shared over AFP. macOS Sierra though Catalina 'fails silently' in this method, letting you turn on AFP in the Sharing preference pane's File Sharing section, even if there are no volumes that AFP can share. (Big Sur can still mount AFP-shared volumes.)

I suggest disabling AFP sharing on any Mac running Catalina or earlier versions that you no longer have HFS+ drives mounted or plan to mount in the future: Splasherino mac os.

1. Open the Sharing preference pane.
2. Click the File Sharing item at left.
3. Click the Options button.
4. If you see an option for AFP, uncheck it. Check 'Share filse and folders using SMB' if it isn't selected.
5. Click Done.

The only reason this typically matters, however, is on other Macs. When you have a stored alias on one Mac that points to another, and which was a connection originally made over Crazys nightmare mac os. AFP. The alias will still try to work if the other computer is sharing via AFP, even if the volume is no longer shared over AFP.

You're A Big Guy Mac Os X

The solution? Gyro cube mac os.

1. Delete your alias.
2. In the Finder, choose Go > Network.
3. Double-click the computer you want to share from.
4. Enter login information for that Mac if prompted. (If may be stored in your Keychain and the login handled silently.)
5. Double-click the volume you want to link to.
6. Select the volume. See below for methods.
7. Choose File > Make Alias or hold down Command and Option while dragging to create an alias.

You can select the volume in step 6 in one of several ways:

• In the Locations section of the sidebar, click the remote Mac, then in the resulting Finder window, double-click the volume you want to make an alias from. Navigate up one level and proceed to step 7.
• In Finder > Preferences, make sure that in the General tab you have selected 'Connected servers.' This will make any mounted drives appear on the Desktop, where you can select them in step 6 and proceed to step 7.
