Mac Os X El Capitan Download
One of the many perks of Mac users that Windows users would never imagine of getting is free OS upgrade. Every time Apple releases the latest and greatest macOS, they always come with zero dollar price tag. That’s why the adoption rate of the latest macOS always goes through the roof. Who could resist the best OS in the planet for their Macs for free?
But unfortunately, the latest and greatest macOS doesn’t always mean the best for your machine, especially if your machine is old.
Restart Mac and Hold down the Option/Alt key at startup and when the drive icon appears then Install OS X El Capitan, click on the arrow below it to start the install. Select Disk Utility When the Disk Utility app launches, choose your Mac’s hard drive and click on the Erase tab. Name your hard drive and select one of the OS X Extended formats.
Even though your machine is still compatible with the latest macOS High Sierra, the older your Mac is, the more strain from macOS that it has to endure. That’s why it’s understandable that some people with older Macs might want to downgrade Sierra to El Capitan, or from High Sierra to Sierra.
How do you downgrade your macOS? And what if you don’t have Time Machine backups to help you?
How to Downgrade MacOS in Easy Steps
The easiest way to downgrade is to use the backup that you have in your Time Machine, and we will discuss it later. But if you don’t have one, you can use the process described below.
The steps that we’re about to discuss will be more or less the same even under different macOS. There would be slight differences in details, but they aren’t essential. So whether you are downgrading from Sierra to El Capitan or from High Sierra to Sierra, or lower, please make a printout or read this discussion on another device so you can do the steps while having the instructions handy.
Step 1: Back Up Your Current macOS
Since downgrading will erase the current macOS entirely, including the files, programs, or documents, it’s wise to back up your important files prior to starting the process. Use external hard drive or cloud-based storage services like Dropbox, OneDrive, or iCloud.
Step 2: Create Bootable Drive of the Previous macOS
How To Update To El Capitan
If you are downgrading from Sierra to El Capitan, you need a bootable drive of El Capitan handy. But if you’re downgrading from High Sierra, you need Sierra.
Download the installer from AppStore, and use the help from DiskMaker X program to create the bootable disk.
Step 3: Erase the Current macOS
Now is the time to erase the macOS that is currently installed on your computer. If you are downgrading from Sierra to El Capitan, this is the time to erase Sierra. Here are the steps.
- 1. Connect your Mac to the internet via Wi-Fi or Ethernet.
- 2. Click on the Apple icon in the upper left corner of the screen.
- 3. Select Restart from the drop-down menu.
- 1. Hold down Command+R, and keep holding the keys until your computer reboots.
This will put your computer into Recovery Mode. - 2. Click on Disk Utility in the OS X Utilities selector.
- 3. Click Continue.
- 1. Select your Startup Disk.
- 2. Click on the Erase tab at the top of the window.
- 1. Enter a name for the file to be destroyed (Like macOS High Sierra or something).
- 2. Select Mac OS Extended (Journaled) from the format list.
- 3. Click Erase.
After the process is complete, quit Disk Utility from the drop-down menu in the upper left corner of the screen to go back to the OS X Utilities selector.
Step 4: Reinstall the Previous Version of macOS
After wiping out your current macOS installation, you need to reinstall the previous version of macOS. If you are downgrading from Sierra to El Capitan, this is the time to install El Capitan. You need to have your installation USB plugged in.
- 1. Connect your Mac to the internet via Wi-Fi or Ethernet.
- 2. Click on the Apple icon in the upper left corner of the screen.
- 3. Select Restart from the drop-down menu.
- 1. Hold down Option while your computer restarts. This will send you to the option to select a startup disk.
- 2. Select macOS El Capitan (or whatever the macOS that you want to install) from the list of startup disk options and it will begin installing on your Mac.
- 3. Click Continue in the installation window.
Just follow the process, and after it finishes, you’ll have your freshly installed Mac ready to roll.

Another Method to Backup and Recover
Apple’s Time Machine is not the only player in the data backup and recover field. Another recommended tool for the job is Tenorshare Data Recovery for Mac.
