What are you using to analyse the space consumed and available on you Mac?<br />
<br />
There are tools like Grand Perspective <a href="http://grandperspectiv.sourceforge.net/" rel="ugc">http://grandperspectiv.sourceforge.net/</a>&nbsp; and DiskInventory - <a href="http://www.derlien.com" rel="ugc">http://www.derlien.com</a>&nbsp;or jDisk Report - <a href="http://www.jgoodies.com/freeware/jdiskreport/" rel="ugc">http://www.jgoodies.com/freeware/jdiskreport/</a><br />
They show you all the files and folders and where space is allocated.<br />

OSX automatically cleans its own logs on a daily, weekly, monthly basis so there is usually no need to manually perform such cleanups in most normal circumstances.

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

Operating Systems

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Mac OS X is the desktop operating system from Apple Inc., found on Macintosh computers. OS X consists of a Mach/BSD-based kernel, operating system interfaces primarily based on FreeBSD and additional frameworks (written in C, C++ and Objective-C providing user interface and application-level services.
