I tried to flash a kali linux iso disk onto my USB using 'balena etcher'. I did this thinking that I would still be able to use my USB as a storage device afterwards but apparently not.
I am using a MacOS Big sur and am using an Intenso USB stick.
I can boot into kali linux which was my intended purpose but I am unable to use my USB stick as a storage device anymore as it appears greyed out in 'Disk Utility'. I tried erasing it but it came up with this error message:
Couldn’t modify partition map. : (-69874)
I have searched for a long time on the internet but have found no solutions that work. Any help would be much appreciated.
