Version, Memory, and Space Requirements for El Capitan

How to check it:
- Click the Apple icon at the top left of your screen.
- Select 'About This Mac.'
The number underneath 'OS X' is your version number.
If you're running a version of OS X older than 10.8, look into upgrading your OS X. Also, Apple notes that Metal is only available on 'all Macs since 2012'.
RAM: 4 GB (preferably 8 GB)
In the same menu you have the 'Memory' tab. If you have less than 4 GB RAM, you'll have to look into upgrading your RAM.
Disk Space: 15 GB to 20 GB of free space on drive
Next to 'Memory,' select 'Storage' tab. In front of the multi-colored bar, you will see the phrase, 'X.XX GB free out of XX.XX GB.' If you don't have at least 15 GB of free space, look into cleaning your Mac with cleanup tool, like CleanMyMac 3.
