TransMac is a utility software that is used to make macOS bootable USB flash drives. It will just ask you to download the DMG file of that macOS version that you want on the USB. It was released in the year 2016. Also, this software is developed and distributed by Acute Systems. It works in a way that once you have downloaded the DMG file which we mentioned before then you just need to import that file into the software. After that, it will format the whole USB drive in the APFS file format. It may take a little longer for the process to be fully completed. Because the DMG file is always encrypted and there is a difference in the file system. These are those reasons which may extend the time period of the process. You don’t have to worry about it because the work will be done.
Furthermore, TransMac is a software that is available for Windows. You must be thinking that it makes a macOS USB but it is available for Windows devices. But, you can make the bootable USB in your Windows device. Then, use it in your Mac devices. Other than that, it has support to Apple File System which is, as you know, is different from any other device. It is a rare feature that is available in very few software. Plus, it has support to create, expand, split, and compress DMG files.
