So first of all I have little experience on this field, but I'm trying to install linux on my personal MacBook Pro from 2017.
I followed a lot of tutorials for this but none of them worked. So I figured I'd ask here.
I have a 64gb SanDisk Ultra Media USB stick lying around. I got it here: https://www.mediamarkt.nl/nl/product/_sandisk-ultra-usb-3-0-flashdrive-64-gb-1262970.html
I grabbed a ubuntu copy from the official Ubuntu website, used Etcher to flash to ISO on the stick. Everything seemed fine, so I eject the stick, restart my macbook into startup manager, but the USB isn't there. Only my internal hard drive shows up. After reading a lot of forums I read that the USB stick should be erased first with GUID partition.
So, I did that, but after flashing I checked Disk Utility and saw that the partition was reverted back to the standard Apple-partition scheme.
What am I doing wrong? All these miracle fixes I see on the internet never work for me, and people say it's so easy to install Linux on your Mac. Well, I also have a MacBook from work, with Catalina, and have the same problem with that one too!
Any help would be appreciated
