You can use your old Mac Operating-system with the brand-new El Capitan, all you possess to perform is usually to develop a different partition for the fresh El Capitan if you possess the Yosemite currently set up. The Beta edition of the OS is obtainable but the last version will be made accessible towards the Autumn time of year of 2015 as speculated by many Apple users. Mac Operating-system X Un Capitan can be downloaded straight from the Apple web site.
