Cloning of a hard drive is an old but useful concept. A mere cloned hard drive can save your precious data and time if the OS X goes corrupt. Other than cloning, the image of volumes can be created and stored safely to access in crisis time. Isn’t it better to clone the data rather than waiting for a data loss situation.
A slow Mac is intolerable. But there are some particular reasons that makes the Mac OS slow and non-responsive. These reasons may be broadly explained as the unwanted data, applications and widgets that exist on our Mac hard drive consuming some amount of space on the HDD. These clutters need to be removed from Mac volumes and hard disks immediately in order to free up spaces.
