Once Install Disk Creator opens (Figure A), click on the top drop-down and select the correct USB drive to be used. By default the tool will select your local drive-do NOT use that drive for the. Use a Mac OS X installation Disc. If you’re unable to use Internet Recovery Mode or create a bootable USB installer, you can still use a Mac OS X installation disc. These discs are available for OS X Snow Leopard, OS X Lion, and OS X Mountain Lion. If your Mac is from 2012 or earlier, there was an installation disc in the original box.

The idea behind a macOS Clean Install

When you install a new major version of OS X, or after some time has passed, it is a good idea to do a clean install (that is, to erase the disk you are installing OS X onto as part of the installation process).

It used to be common practice to occasionally run a clean install, and then manually migrate all the files and settings over in order to get a completely fresh start. However, it has been shown in recent times that in the vast majority of cases if you simply run a clean install, then duplicate your old home folder to your new disk, you will get all of the same advantages as a clean install followed by manual migration, with a small fraction of the effort.

Mac Clean Install Procedure

Here is the clean install procedure which can be performed at least every time a new version of macOS is released:

1. Download the macOS installer from the App Store. You can download macOS Big Sur by clicking here.
2. Backup all the data to an external disk with a clone. Two options are to use Duplicate (a free utility which can copy and paste an entire bootable volume), or Mac Backup Guru (a paid, fully featured backup utility with unique incremental backups capability) for that.
3. Create a bootable USB Installer with Install Disk Creator and boot from it. Erase the startup disk and install macOS onto it. Boot up from this newly created startup disk.
4. Note: The Finder’s built-in “Copy” and “Paste” will not work for the following.
   Go to the backup disk and use Duplicate (free) or Mac Backup Guru to right-click and select Copy on the home folder (eg: External Backup/Users/Bob) and then Paste on the Macintosh HD/Users folder on the startup disk. This migrates all of your personal data and settings to your new home folder.
   Then migrate the applications by selecting Copy on the External Backup/Applications folder on the backup disk then Paste on the startup disk (eg: Macintosh HD). This will copy all of the applications which are present on the backup disk but not present on the startup disk to your new Applications folder, and automatically skip any applications which are already on the startup disk.

At this point, after a reboot and some minor adjustments (the Dock may not have your previous configuration for example, if you did this while logged into the same user account as you just updated), your new OS should be indistinguishable from your previous one, while being faster and smaller due to reduced clutter.

With a bootable Ubuntu USB stick, you can:

• Install or upgrade Ubuntu, even on a Mac
• Test out the Ubuntu desktop experience without touching your PC configuration
• Boot into Ubuntu on a borrowed machine or from an internet cafe
• Use tools installed by default on the USB stick to repair or fix a broken configuration

Creating a bootable USB stick is very simple, especially if you’re going to use the USB stick with a generic Windows or Linux PC. We’re going to cover the process in the next few steps.

Apple hardware considerations

There are a few additional considerations when booting the USB stick on Apple hardware. This is because Apple’s ‘Startup Manager’, summoned by holding the Option/alt (⌥) key when booting, won’t detect the USB stick without a specific partition table and layout. We’ll cover this in a later step.
