Installation of it is also a problem so many compatibility issues without any reason I feel as compared to other operating systems which let you install it even if the recommended specifications of do not match. For every solution they ask you to go to Apple Authorized dealers even for hard disk upgrade or RAM upgrades. People thing no other Ram or Hard Disk Cannot be used in it.
