Mac El Capitan Installer

Jul 18, 2016 This update is recommended for all OS X El Capitan users. The OS X El Capitan v10.11.6 Update improves the stability, compatibility, and security of your Mac, and is recommended for all users. This update: Resolves an issue that may prevent settings from being saved in accounts with parental controls enabled. This is how to install Mac OS X 10.11 'El Capitan' on an unsupported Mac Pro. In this video, I use a Mac Pro 1,1 (that has been flashed to 2,1 firmware). Nov 07, 2015 Download El Capitan from the Mac App Store. Head over to your existing OS X environment running 10.9 or later and open the Mac App Store. Search for 'El Capitan' and click Download. The download is completely free if you're running OS X 10.9+. Wait for the download to finish (this could take some time). Format the USB Drive.

Why do you need to download El Capitan through Terminal.

El Capitan is freely available from this link.

Here are the instructions.


Go to Section 4 and click on Download OS X El Capitan.


This downloads InstallMacOSX.dmg to your Downloads folder.


The next section can only be done on a mac that is capable of running El Capitan,

a mac that came preinstalled with an OS later than El Capitan will refuse to do the next bit.


When downloaded open to InstallMacOSX.pkg, double-click on

Download Old Mac Os

that and an installation window will open, this does not install El Capitan

but converts the InstallMacOSX.pkg to the Install OS X El Capitan.app which

you will find in your Applications folder, it should be 6.2GBs in size.


(If the installation window asks which disk you want to install to, you must pick

Mac Os El Capitan Installer

the disk that you are booted to at the time. Not any internal or external disk that

you want to eventually install El Capitan on, that is for later.)


To start the installation of El Capitan double click on the Install OS X El Capitan.app.

The copy of the install app self deletes after installing El Capitan, so make sure you keep a copy of the InstallMacOSX.dmg

if you need it in future, or you could just make a copy of the Install OS X El Capitan.app prior to installing and moving it to

an external drive for safe keeping. It is also possible to create a bootable USB installer disk using the Install OS X El Capitan.app

in the Applications folder and the createinstallmedia command in the Terminal app.
