I helped another customer on a third party website, where I earn supplemental income answering computer and technology related questions. This is the customers question:
Re-downloaded a fresh copy of 'Install OS X El Capitan' from the App Store, re-ran Unibeast 6.2.0 on an erased 16 GB USB drive; same problem repeats when attempting an install of El Cap on a new computer: Intel Core i7 6700 CPU, Gigabyte GA-H170N-WIFI motherboard, BIOS version F4c, Kingston 16 GB DDR4 RAM, Samsung 850 EVO 250 GB SSD. Feb 01, 2017 OS X El Capitan is the twelfth major release of OS X for Mac computers. It was released on September 30, 2015. Some users have reported an issue where Mac refuses to finish booting after updating to OS X EL Capitan. If your Mac will not start up, stalls on a gray screen with an Apple logo, here is how you troubleshoot.
Purchased Turbotax Deluxe at Sams. Unable to install. Tried to download OS X 10.11.
Stated it cannot be installed on my computer. How can I do my taxes?
This individual owned a Macintosh with the following specifications:
* OS X Yosemite
* version 10.10.5
* iMAC 27-inch late 2013
* processor 3.2 GHz Intel Core i5
* Memory 16 GB
Newer versions of Turbotax, for example 2017 versions, now require MAC OS 10.11. This is known as El Capitan. In order to upgrade your MAC operating system, you must now have an Apple ID.
If you have installed El Capitan before, then all you have to do is browse to the “Apple Store” on your macintosh. You need to login with your Apple ID. Click on the “Purchases” tab.
A list of all your previous purchases will populate. Apple considers operating system upgrades as purchases. Select “El Capitan” and then click on “Download”.
Depending on the speed of your Internet connection, this download can take hours to complete. If you have NOT installed Apple MAC OS El Capitan before, you will need to download El Capitan from this alternative Apple Store download link. You will need to access this link from your Macintosh computer.
Once El Capitan finishes downloading, then the installation will open. You will need to accept some terms of conditions. Keep clicking “Next” until you come across a “Restart” window.
Click on “Restart” and your Macintosh will reboot and begun upgrading from Apple MAC OS 10.5 Yosemite to Apple MAC OS 10.11 El Capitan. You can click on the Apple icon and select “About this MAC” to verify your operating system. You should see MAC OS 10.11 populated.
Here is a bonus tip. Now that you have successfully upgraded your Macintosh to El Capitan, you can upgrade other MACs to El Capitan by just logging into the Apple store with your Apple ID and clicking on “Purchases” tab.
You can then download El Capitan from this tab. Finally, if you are having problems upgrading to El Capitan, it might be because your Apple Macintosh hardware is NOT compatible.
To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Check compatibility
The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.
If a macOS can't be used on your Mac, the App Store or installer will let you know. For example, it might say that it's not compatible with this device or is too old to be opened on this version of macOS. To confirm compatibility before downloading, check the minimum hardware requirements:
- macOS Catalina 10.15 hardware requirements
- macOS Mojave 10.14 hardware requirements
- macOS High Sierra 10.13 hardware requirements
- macOS Sierra 10.12 hardware requirements
- OS X El Capitan 10.11 hardware requirements
- OS X Yosemite 10.10 hardware requirements
Download macOS using Safari on your Mac
Reinstall Os X El Capitan
Safari uses these links to find the old installers in the App Store. After downloading from the App Store, the installer opens automatically.
- macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
- macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
- macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
Safari downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.
