What is a macOS bootable USB and why do I need it?
A macOS bootable USB is a USB drive that contains a bootable version of the macOS operating system. This allows you to install macOS on a Mac computer without having to use a CD or DVD. You may need a macOS bootable USB if you want to install macOS on a new Mac, or if you want to reinstall macOS on a Mac that is not functioning properly.
Having a macOS bootable USB can also be useful if you want to test out a new version of macOS before installing it on your main Mac. Additionally, a bootable USB can be used to troubleshoot issues with your Mac, such as running disk utility or reinstalling the operating system.
What are the system requirements for creating a macOS bootable USB from Windows?
To create a macOS bootable USB from Windows, you will need a few pieces of software and hardware. First, you will need a Windows computer with a USB port. You will also need a USB drive with at least 16GB of free space. Additionally, you will need to download the macOS installer from the Apple website, as well as a tool called TransMac, which allows you to format and write the macOS installer to the USB drive.
You will also need to make sure that your Windows computer is running a 64-bit version of Windows 10 or later. This is because the macOS installer is a 64-bit application, and it will not run on 32-bit versions of Windows. Additionally, you will need to have administrative privileges on your Windows computer in order to use TransMac and create the bootable USB.
What is TransMac and how do I use it to create a macOS bootable USB?
TransMac is a software tool that allows you to format and write the macOS installer to a USB drive from a Windows computer. To use TransMac, you will first need to download and install the software on your Windows computer. Once installed, you can launch TransMac and select the USB drive that you want to use to create the bootable USB.
To create the bootable USB, you will need to select the macOS installer that you downloaded from the Apple website, and then use TransMac to write the installer to the USB drive. This process can take several minutes, depending on the speed of your USB drive and the speed of your computer. Once the process is complete, you will have a bootable USB drive that you can use to install macOS on a Mac computer.
How do I download the macOS installer from the Apple website?
To download the macOS installer from the Apple website, you will need to visit the Apple Support website and click on the “macOS” link.

Once the download is complete, you will need to extract the .dmg file to a folder on your Windows computer. You can do this by using a software tool such as 7-Zip, which allows you to extract the contents of a .dmg file to a folder. Once the .dmg file is extracted, you can use TransMac to write the macOS installer to a USB drive.
Can I use a USB drive that is smaller than 16GB to create a macOS bootable USB?

Once you have selected the macOS bootable USB, the Mac will boot from the USB drive and you will be able to install macOS. You can then follow the on-screen instructions to complete the installation process.
What are some common issues that I may encounter when creating a macOS bootable USB from Windows?
