My mac cannot start ,always stuck at kernel panic PCI pause: SDXC
So i entered recovery mode and in terminal wrote "fsck_hfs -f /dev/disk1"
Disk1 is Mac ssd drive and there is another one in the optibay.
i did that thanks and i didn't format my ssd drive and when the internet recovery finished i found that my mac restored to it's previous state with all installed programs and even files on desktop !
Have you checked disk utility if There is another disk? Have you checked if you've did an extra partition on your main disk? Have you checked if you have any USB disk?
