Apple has recently released macOS Ventura, a new operating system version. If you are fascinated by the unique features of macOS Ventura and want to clean install macOS Ventura on Mac, you are on the right page. This article will tell you what to do before the clean installation of macOS Ventura and how to perform it with a bootable USB drive.
A clean install is an installation in which any previous version will be deleted. Compared with an upgrade, a clean installation seems more suitable for computer users who want a new start on their Mac devices. However, if you're going to retain your files, apps, and settings, perform an upgrade, and if you want better performance and a clean Mac OS, a clean install is a good choice.
A clean installation is always preferred among computer users. You can benefit from a clean installation of macOS Ventura on Mac.
- Enjoying better stability and responsiveness.
- Having better compatibility with applications.
- Making full use of storage space.
- Improving performance and efficiency.
Before starting the clean installation process, many things need our attention. Let's check what they are:
Not every Mac computer is compatible with macOS Ventura. Therefore, it is essential to know whether your system will support it before installing the macOS Ventura on your Mac. The following are the devices compatible with macOS Ventura:
- Mac Studio (2022)
- Mac Pro (2019 and later)
- MacBook Air (2018 and later)
- Mac Mini (2018 and later)
- iMac (2017 and later)
- iMac Pro (2017 and later)
- MacBook (2017 and later)
- MacBook Pro (2017 and later)
Firstly, you need two external hard drives, one for creating the bootable installer and another for backing up files on your Mac. Creating a boot disk requires at least 16GB of storage space.
Secondly, before making any clean install, you should know how much storage space you need. So, ensure that you have a minimum of 16GB of free space for everything to run smoothly on your Mac because the installer of macOS Ventura is about 12GB. However, you still need extra space to install software and applications on your Mac. And if you don't have the free space required, you can use macOS Optimize Storage to clean up the junk.
If you have critical data stored on your Mac, you should back up your Mac computer. This is because a clean installation will wipe every file stored on your Mac. That is why backup is necessary. You can use any of the ways below to back up your data:
Method 1. Using Time Machine
Time Machine is a built-in backup feature of macOS. It allows you to automatically back up your data once set up and restore it after the clean installation. Time Machine can back up apps, photos, music, email, and documents. And you need an external drive to use Time Machine. It seems that Time Machine can save most personal data. However, it does have some limitations. For example, it has no cloud storage. In addition, Time Machine cannot back up:
- iOS devices.
- Network settings.
- Email messages or accounts.
- iCloud content.
- Specific system files or applications.
Method 2. Using Professional Backup Software
Time Machine is an excellent backup and recovery tool for Mac, but you should recognize its shortcomings when backing up your Mac device. And if you want to back up everything on Mac, you can turn to third-party backup software, such as EaseUS Todo Backup, for help. EaseUS Todo Backup is one of the best backup software for Mac.
EaseUS Todo Backup for Mac is great for backing up data from any Mac device. In addition, it allows you to back up the entire Mac computer, create an automated backup, change the iTunes backup location, compress the backup for saving storage space, and clone a USB drive. Besides, it is easy to use because you can back up your Mac with three simple steps.
The following are the steps to back up your Mac.
Step 1. Launch and run EaseUS Todo Backup for Mac.
Click the first Backup tab or simply click the + button in the bottom-left corner to create a backup project - name the backup project and click OK.
Step 2. Set up the backup destination where you want to store Mac files as backups, automatic backup frequency, etc and click OK.
Step 3. Add files and folders to the backup project.
Click File+ to selectively choose files and folders to add to the backup and click the blue start button to back up your Mac to another drive or external device.

1. Is it worth doing a clean install of macOS?
A clean install lets you clear old files before installing the OS onto a freshly formatted disk. Besides, a clean install is necessary before selling your Mac or passing it on.
2. Why does my Mac keep saying error while installing?
If your Mac says an error while preparing an installation, boot into Safe Mode and check your date and time settings. Then, boot into Recovery Mode, run First Aid, and try to reinstall the OS without erasing the drive. If the issue persists, erase the drive and try to reinstall the OS.
3. Does factory resetting a Mac remove viruses?
In most cases, yes. However, it will not be helpful when your backup, recovery partition, or other devices are infected. Besides, resetting the Mac will not help if it was infected with a rootkit enabling administrator-level access to your device.
4. Should I restore from Time Machine or reinstall macOS?
If your system or startup disk is destroyed, you can restore your data by utilizing Time Machine to back up your Mac. However, it would be best if you first reinstalled macOS on your Mac before you restore your data using your Time Machine backup.
