Are you wondering if you got more space on your Mac/Macbook hard disk? Figuring that is so easy! Just follow the instructions below for MacOS X.

In today’s era we should keep as close an eye on our hard disk space and usage. Still, even the largest drives they’ll fill up eventually.Here is how to check your disk space on OS X, here’s where to look.

1. Click on the Apple icon. and press “About This Mac” from the menu that will slide down

2. Click “System Report”, This will generate a System Report, The default tab is “Overview”.

3. Click on the Storage tab. This will show how storage is consumed for all of your connected hard drives. You will notice the size of your movies, music, installed programs, and other files take up, as well as the free space you have remaining, as for iMac I only having the system files.

TIPS

If you’re trying to get more space on your computer, note that you can’t change your hard disk space easily by dragging and dropping your files into trash; you must empty the trash to make more space.

A bit is the most basic unit of data size in current computers. It can either represent “0 or 1” (from the Binary numbering system, NOT decimal). There is no unit currently smaller than a single “bit” of data.

1 Byte is 8 bits.

1 Kilobyte is equal to 1024 Bytes.

1 Megabyte is equal to 1024 Kilobytes.

1 Gigabyte is equal to 1024 Megabytes.

1 Terabyte is equal to 1024 Gigabytes.

There are a different data size units, some of which are confused by each other. The “byte” named units are standard for data size on storage devices. Two unit systems commonly confused are Megabytes (MB) and Megabits (Mb), Gigabytes (GB) and Gigabits (Gb), Kilobytes (KB) and Kilobits (Kb), etc, etc.

The “bit” suffixed units are more commonly used for measuring data sent over a network or through a “computer bus”, whereas the “byte” suffixed units are used to measure the size of stored data.

The two can be intermixed, but standards dictate that “byte” suffixed units are used for data storage and “bit” suffixed units are used to measure the size of data-in-transit (being moved through a circuit, such as from the CPU to the RAM, CPU to the Hard Drives “bus” from a Wireless adapter to a router, etc.).

On most file systems, files take up more space than their actual size. Refer to a definition of “cluster”.
