Way too complicated but everything else on a mac is way better than windows.The installer for macOS Monterey, macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra downloads to your Applications folder as an app named Install macOS. I have been a mac user for 2 years now and swear by them but this is probably one of the dumbest things I have seen yet. This is the first convoluted thing on mac that I have come across as compared to windows. I too, got the "couldn't unmount disk" message so I went to the drive on the left, right clicked and clicked "unmount disk" then went ahead and erased it. I went to utilities like the previous posters said and simply clicked "erase." No need to partition, don't understand why you would need to do all of that to do a simple format. On a PC, you simply right click and select "format." The reason I wanted to do this on the mac is because I have an 8gb usb flash drive that for some strange reason, when I deleted all the files it still showed only 1.5 gb available making it impossible to put any more than 1.5 gigs of new data on it.

Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Set the format type to Mac OS Extended (Journaled.)
