I want to clean my hard drive, because I got only 68Gb left (oh dear - in 2000 it was a miracle))) I started with "About this Mac" Storage info. It states that nearly 24,7Gb is spent on "Other". What is this "Other"? I tried with CleanMyMac and DaisyDisc but it was worthless. Is it an actual size of the OS or what? I am quite familiar with the disk cleaning in Windows but not so with the Mac OS. As a freshman of the platform I ask for your help.
