Apple's latest operating system, Mac OS 10.11 'El Capitan' is now available. With any new operating system, if you rely on your computer for work, it's always best to wait to ensure that it will work for everything you need. A good rule of thumb is to wait until the second update after the release. When you're ready to install El Capitan, Apple makes it simple -- just go to the App Store on your Mac, click on OS X El Capitan, and then click 'Download.' But if you have multiple Macs you'd like to update, there's a faster way than having to download this large update file on every computer.
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. Can't install OSX el capitan, stuck on installation screen Hello! Was trying to instal el capitan on my macbook, the installation starts and after a few minutes stops and a messaging saying the os x could'nt be install on the computer, please contact the software editor to get help. All you need to perform the installation is a spare 8GB or larger USB thumb drive, an external drive to back up all your data to (if you have any), and a copy of OS X 10.11 El Capitan. OS X 10.11 El Capitan can be downloaded from the Mac App Store. Use Disk Utility to re-initialize the internal drive. Launch CCC and clone the external drive (with the fresh install) to the INTERNAL drive. Now you have El Cap on the internal drive, too. Power down, disconnect the external drive, and see if you can boot from the internal drive.
1. First, click 'Download' on OS X El Capitan.
2. Once the download completes, do not continue with the installation.
