I have tried so many times to get persistence working on my Ubuntu USB using macosx(Dual-Boot), but none of them work. I followed all the steps correctly, including how to format my USB drive, but I just can't get persistence to work on it. Ubuntu is so cool and want to use but nothing gets saved because it is not persistent. Please help me in getting the correct method on installing Ubuntu on a USB drive with persistence using mac.
P.S. These are the following attempts on Ubuntu:
1) normal installation using Unetbootin (off course it is not persistent)
2) using syslinux and Unetbootin(USB didn't show up in boot loader)
3)Trying to get Mac Linux USB loader working with github and xcode but didn't work even after following the ReadMe file (I can't buy the software cuz I am a student not allowed to buy things online using a credit card)
Thanks for helping me btw.
I have watched numerous videos as well and I am no professional in this field, so I have nervously followed many youtuber's videos and not done anything personally by me.
