I'm trying to install Fedora 29 next to OSX on my macbook air. I downloaded the image and verified the checksum. Then I formatted usb to OSX Extended Journaled file system, and created bootable usb using
diskutil unmountDisk /dev/disk2s2
sudo dd bs=1m if=./Fedora-Workstation-Live-x86_64-29-1.2.iso of=/dev/rdisk2
However, when I start my mac from the USB with the option testing & installing Fedora, I get the following error
This is not the first time that I'm installing Fedora to my mac, but I was getting the same error before, but still the media allows me to install it if I directly try to install it without testing it, so what is wrong ? why am I getting this error ?
Edit:
As I've stated, the checksum is OK
grep '^SHA256' *-CHECKSUM | awk -F '[()=]' '{ print $4 " " $2 }' | shasum -a 256 -c
Fedora-Workstation-Live-x86_64-29-1.2.iso: OK
