If you have tried partitioning a hard drive without any previous experience then you understand that it is a daunting task. Handling the Mac partition manager is not as easy as it sounds. Once you learn the process, it gets pretty easy. The good thing is that you don't need any external or third-party tools for partitioning.
- When you partition, you are dividing the hard drive’s storage space into sections. For example, you can partition a 1TB hard drive into two 500GB sections. Each section would appear on your Mac.
- To do so, select your hard drive from the left panel and then click the Partition button at the top of Disk Utility. On the pie graph on the left, click the wedge that represents the partition you.
So, in this article, we are going to guide you through partition and un partition on Mac without any hassle.
Part 1. What Does Other Mean in Mac Storage?
Before you step into detail, first you need to understand what exactly the term partitioning means.
By Partitioning your Mac drive, you split the hard drive in two or more separate, usable systems. This feature allows the users to run multiple OS on the same system/device such as Windows and macOS simultaneously. You can even run two versions of macOS on the same system. The partitioning also divides the storage space on the hard drive. And a specific portion goes to each partition. So, if you are running out of storage, it is advised that either you extend the storage or avoid partitioning at all.
Here are some advantages of Partitioning that will convince you that it is beneficial for the users.
- You get to switch between different versions of OS X including Tiger, Leopard, or Snow Leopard at the same time.
- The users can use the Boot Camp Assistant to run Windows OS on the Mac system. This way, you get to save some bucks and efforts to maintain two separate systems for your needs.
- During the startup Volume disk errors, it is needed that the repair program is run from another volume to fix the errors. Partitioning of Mac allows the users to keep a disk where the bootable copy of OS X is stored and it can be used to run Disk Utility.
- You can share your iPhoto Library between two or more user accounts on Mac after partitioning.
- Partitioning also allows Mac users to manage their backups efficiently. You can use Mac Time Machine without using an external hard drive.
If you opt-out for partitioning, make sure that your Mac has enough space otherwise the disk performance would decline and you might experience some working issues in both drives.
Part 2. How to Partition a Hard Drive on Mac?
Partition Hard Drive For Mac And Pc
There are two methods that allow the users to create a partition on Mac. The first method is using Disk Utility and the second one is using Boot Camp. Both these methods work great to partition hard drive on Mac.
Method 1. Disk Utility:
The Disk Utility is used when you wish to partition Mac and wants to install a different version of the same OS. As we all know, Disk Utility can perform various tasks on Mac including repair and partition. The Mac partition Manager is used for this process. Before you initiate the process, it is advised that you create a full backup of your device data in case some fault arises. This way, if anything goes wrong, you will still have a copy of your data files.
Now, follow the steps given below to partition your Mac drive:
- Press Command + Shift + U keys from the keyboard or access the Utilities in the Application folder. Open the Disk Utility application and select the Mac Internal drive.
- You will see two options in the window, i.e. First Aid and Partition. Click on the Partition option and hit the '+' icon.
- A new partition will appear on the screen and you can set the storage space according to your requirements.
- Give a name to the new drive and tap on the Apply button. You might have to click on a lock symbol to finalize the actions.
You can make changes to the drive even after you've created the partition. When the process is finished, the partition will be visible on the main drive. The partition size can also be modified later when required.
Method 2. Boot Camp:
Remember that you cannot partition hard drive on Mac using Disk Utility if you want to install Windows on the other partition. The Boot Camp Assistant is a handy application for partitioning your Mac drive so that you can run and operate macOS and Windows altogether. In the later version of Mac, this application is pre-installed, so you only need to open it and follow the steps below:
- Open Application and go to Utilities. There you will find the Boot Camp Assistant. Double-click on the option to open the Boot Camp and print a copy of the installation and setup guide.
- Click on the Create or Remove a Windows Partition option and Continue with the steps.
- Now, you have to select a hard drive for partition. If you already have multiple drives, you can select any one which you prefer.
- Determine the size of the partition for Windows OS. You can't make a partition smaller than 5 GB and it is recommended that you at least keep 20GB of space for your partitions.
- Click on the Partition button at the bottom of the interface and your new partitions will be ready to use.
Now all there is left to do is to insert the Windows installation disk and you will have multiple OS working on the same Mac system.
