What you need to create a bootable installerA 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 macOSDownload: 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 TerminalConnect 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.
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.

This guide is about the Show Remaining Battery Life in the Mac OS X Menu Bar. I will try my best so that you understand this guide very well. I hope you all like this guide Show Remaining Battery Life in the Mac OS X Menu Bar.
If you've ever wondered how much battery life is left in your MacBook, MacBook Pro, or MacBook Air, set the battery icon in the OS X status bar to show some additional information, such as the percentage remaining. This will give you an instant idea of ​​how long you can use your Mac. The adventure after bongo cat mac os.
Enabling the battery indicator on a portable Mac is pretty easy, you can do it from almost anywhere in OS X, as long as you see the menu bar.
How to show the percentage of remaining battery on a MacTo display the remaining battery life on the Mac menu bar in all versions of OS X, follow these steps:
Click the battery icon in the upper-right corner of the Mac menu bar
Drag down and select Show Percentage to check – note that older versions of OS X have two View options and select Time or Percentage
This provides a constant update on battery life and works on all configurations of Mac laptops. I think the remaining time is the most informative, a feature that now requires the user to pull down the battery menu to see, but the remaining percentage is also useful. The options available in this menu depend on the version of OS X you are using.
In newer versions of OS X, which only show the percentage of battery remaining on Macs, you can click the battery icon to reveal additional information, such as the actual time remaining before the battery runs out. In addition, modern versions of OS X can also tell you which applications are running on battery and power by giving a quick overview of the same menu bar, a really great feature for laptop users.
Show the remaining battery life in the OS X Battery menuWhile all versions of OS X let you see the remaining battery on your Mac by clicking a menu item and dragging down the menu bar itself, not all versions support the ability to actively display the remaining time on the menu bar.
But if your Mac has a much older version of Mac OS X, there are actually three options in the battery menu: just the icon, time, and percentage. This looks like this:
On either a newer or older Mac, the battery indicator always appears in the menu bar, either as a percentage or for the remaining time.
You can also use the remaining time meter to indicate the elapsed process that may consume battery life, such as the Flash inactive browser tab. If you find it flies down quickly, you probably have a wild app in the energy department.
The remaining percentage is basically exactly the same as what you'll find in the iOS world on the iPhone and iPad, where it's just as useful, if not more so.
I recently got a MacBook Air 11.6 ″ and when they showed it to a friend, they complained that they didn't see the remaining battery life at the touch of a button, as you can with past MacBook Pro physical batteries. This is true, but you can do this by setting the Mac OS X menu bar to display the remaining battery life as either a percentage or a percentage in the operating system.
