If you've always wanted to partition your Mac's hard drive so you can run a separate operating system — including the launch of macOS Big Sur — in tandem with your current one, it's surprisingly easy to do so thanks to Apple's built-in disk utility program. Here's how to partition your Mac.
What is a disk partition?
Partitioning your Mac is basically splitting your hard drive into separate, usable systems. It makes it possible to run two separate operating systems on one device, like Windows and macOS, or two versions of macOS (like Catalina and Big Sur).
Note: If you want to run Windows on your Mac, Apple's Boot Camp assistant will automatically make a partition for you. Here's how to install Windows. Sawan music app for mac.
It is important to note that partitioning your hard drive also splits up your available hard drive space. Each partition will take up a portion of your usable storage. So, if you are running low on storage capacity on your hard drive, we don't recommend partitioning.
Before you start
The most important thing to do before making any changes to your hard drive is to back it up. Seriously. Back it up. Please. Time Machine is the easiest way to back up your data if you don't already have another system in place.
Second, make sure you have enough free disk space to properly run a secondary operating system. Shoot for at least 30GB free, though I recommend closer to 50GB if you have it available.

How to access Disk Utility on Mac OS X
The fastest way to access the Mac OS X partitioning app is to press Command ⌘ + Space to open the Spotlight Search and begin typing 'Disk Utility' - the autocomplete will kick in after 'Disk', so we won't have to enter the whole thing.
Also, if we connect an unformatted drive to our Mac, the system will automatically prompt to initialize the disk. Clicking the 'Initialize.' button will open Disk Utility.
How to resize and create partitions on Mac OS X with Disk Utility
By default, Disk Utility will open with the Mac OS X system partition selected, showing a breakdown of its usage.

As you can notice, most of the app's options are grayed out. To resize the partition and create a new partition - to use with Time Machine or to install an alternative operating system - we need to select the parent drive.
Run First Aid first
Partitioning is relatively safe, but it always carries the risk that something could go wrong, and we could lose our data.
To reduce the risk, it's a good idea to check the disk for errors. On Mac OS X, we can do that by running First Aid the drive or partition.
On a normal drive, it will take just a couple of seconds, and offer some peace of mind.
Resize a partition and create new partitions
With the drive selected, we click the Partition button to change the disk's partitions.
Clicking on the '+' will halve the capacity of the currently selected partition and create a new partition of equal size.
Using the slider on the partition pie, we can shrink or enlarge the new partition.
There are a few different file systems to format the new partition. The default is OS X Extended (Journaled).
A journaling file system will keep track of file and directory changes that aren't yet committed to the primary file system, by recording them in a data structure called 'journal'. This way, in the case of a system crash or power failure, the changes won't be lost.
The Case-sensitive option will differentiate between files or directories with the same name written with different case letters, such as 'file' and 'File'. This is the default setting for the most popular Linux file systems.
The encrypted options will encrypt and password-protect the contents of the partition. Make sure not to forget the password, because it will be next to impossible to recover the data.
Pgp for mac os x free download. MS-DOS (FAT) is the most compatible option. Any PC, operating system, and other devices (Smart TV, car stereo, etc.) can access FAT partitions. However, FAT has a file size limit of 4GB - 1 byte per file; it can't handle larger files.
ExFAT is the latest version of FAT, which has a theoretical file size limit of 16 Exbibytes = 260 bytes. Windows 7, 8.1, and 10 will recognize ExFAT but it won't work on Windows XP without Windows update KB955704, or on Windows Vista without SP2.
Disk Utility doesn't have an NTFS option. We will need an alternative app to format a partition as NTFS.
Apply the changes
Until we click on 'Apply', nothing will change on the hard drive. We can cancel anytime, and it will be like we never run Disk Utility. Epson v500 drivers download.
Disk Utility applies most of the changes in real time, without the need to reboot or boot on an external environment.
After creating a new partition and if we haven't set up Time Machine yet, the system will ask us if we want to use the new partition for our Mac OS X backups. Feel free to decline. Download apple mac os x theme for windows 7.
