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.

How to Install macOS 10.15 Catalina Final Update without Mac App Store? If you are Mac device user and wants to free download and install the latest macOS Catalina 10.15 Final Update on your computer or laptop officially and directly from Apple server then you can simply navigate to this option; App Store Software Update. Global Nav Open Menu Global Nav Close Menu; Apple; Shopping Bag +.
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
MyVolumein 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
Yto 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.

The latest macOS released by Apple is the Mac OS Catalina. It is the sixteenth release from them. It was released on the 7th of October in 2019. It has succeeded macOS Mojave and is preceded by the upcoming macOS Big Sur. Catalina is unique as it is the first Mac OS so far that supports only 64-bit applications(32-bit applications are not supported on this operating system at all).
The macOS Catalina 10.15 was extensively praised for its dedication to the user's security which is something that is of paramount importance and often overlooked in favor of other features. The introduction of many new system features and applications were greatly enjoyed by users. The ability for Mac users to now work with both their Mac and iPad simultaneously was seen as of the greatest additions.
Despite some great improvements, there were also certain difficulties faced and complaints raised by users. The decision to allow Mac Os Catalina and Mac OS sierra to only run 64-bit applications was not seen favorably by many who could not run their 32-bit applications on it. Although the security additions were excellent, many users found the security system irritating to use.
Whenever the user wanted to provide access to any piece of data, macOS Catalina would ask them to grant permission each and every time. Although this was done for the user's good, it was found to be aggravating at times.

The Voice Control feature can be simply turned on using Siri or it can be accessed under the System Preference's Accessibility tab.
Gatekeeper
Although Gatekeeper is an app that has been around on the macOS for a long time, it's security protection mechanisms have gotten much stricter than before. This security app used to only check new apps that were to be downloaded once. Now, apps are checked at each and every level which means that users can be rest assured that nothing dangerous will get past Gatekeeper. At the same time, many people are not fans of this as it can be exasperating to have to wait for their apps to get checked like this every time. Thus, some people prefer to disable certain parts of Gatekeeper so that they can save time when new apps are being downloaded.
