RoroMush Posted April 8, 2020 Share Posted April 8, 2020 Hi Guys, I was finally able to get my Catalina installer to boot using by changing EC0 to EC 4543305f 45435f5f. Huge headache with this as it took me a good couple of days to fix the error. The good news is I can make it to the installer but now the problem is now the Catalina installer gets stuck at 2 minutes with the error code showing disk25s1 is not convertible to APFS. My Troubleshooting Steps: - Tried another NVMe drive, with same results - Checked Samsung Magician for updates, no luck - Formatted the drives in Ubuntu, same exact installer error. For some reason the disks always show as "Writable: NO" Hardware: - Asus Z390-E - Intel i7 9700K - Samsung 970 Pro - 16GB Crucial - Intel UHD Graphics Is there something wrong with my kexts or config? Thank You! EFI.zip Link to comment https://www.insanelymac.com/forum/topic/343330-disk-not-convertible-to-apfs/ Share on other sites More sharing options...
ameris_cyning Posted April 11, 2020 Share Posted April 11, 2020 It's possible that its an issue with the NVMe controller. Do you have a USB SSD that you could try?
