How can I create a persistent live USB Stick for xubuntu 20.4 on a mac?
I tried following attempt: https://www.makeuseof.com/tag/how-to-boot-a-linux-live-usb-stick-on-your-mac/ until the balenaEtcher part, but it is not persistent because as soon as I restart ubunto all changes are gone.
To fix this I tried https://www.quora.com/How-do-I-add-persistence-to-a-live-Kali-Linux-USB-drive-on-Mac but I couldn't get past the 2nd step
in terminal, type fdisk /dev/sdb (use YOUR correct path here)
I got this in the terminal and couldn't proceed.
fdisk: cannot open /dev/loop0: Permission denied
fdisk: cannot open /dev/sda: Permission denied
fdisk: cannot open /dev/sdb: Permission denied
I tried also this attempt: https://www.youtube.com/watch?v=mDRbTHCoj8U where I got stuck on the mac Linux USB Loader writing the iso file on the USB Stick. The program just got stuck and looked also quit different than on the video (it's 5 years old, that might be why).
My USB Stick has the size of 32 Gb in case it's relevant. The computer I use is a MacBook Air (11 Inch, Mid 2012), macOSMojave 10.14.6.
