However, I would suggest you keep it as root:root that way you won't hurt the file. Feel free to change the ownership of the resulting file if you'd like read/write permissions. Note: The sudo is required to directly read the device.

dev/sdg2 8565260 8005644 559616 94% /media/alexis/Install macOS CatalinaĪs we can see, the Filesystem column shows us the exact device name. What you can do to determine the device is use df:įilesystem 1K-blocks Used Available Use% Mounted on If so, you'll get something like /media//. When inserting your USB thumb drive, it should auto-mount the file system. A first one, which is 200Mb, a second one with Catalina, and a third one with Majove. In my case, it was #2 because there are three partitions. IMPORTANT: You will need to determine the source on your computer. Sudo dd if=/dev/sdg2 of=iso/macos-catalina.iso I'll consentrate on Catalina anyway since it's the modern version. (At least I think that's not really an ISO, but it should be close enough.) I've done so using dd and I know it worked because Majove started to boot as expected, although it gets stuck really quickly. So my first step was to extract the drives and put them in a 'fake ISO' file.

I had several Linux updates that required a reboot anyway, after a couple of weeks.) I had to reboot by connecting to my server from another computer. I tried that and majored (again) in getting my X-Windows locked up. from the interface, it is clearly marked that it is possible to give a VM direct access to a USB port. I can't just boot the USB, though, since I want to install the OS on a VM. The drive I've got is a 16Gb which is enough to fit the newer version (as of Dec 2019), Catalina which requires about 8Gb and the previous version, Majove, which is about 6.5Gb. You can get a copy ready to install on a USB thunk drive. I just got my copy of Catalina and Majove.
