Moderators Jake Lo Posted June 7, 2018 Moderators Share Posted June 7, 2018 Did you upgrade to latest Clover? Did you format to APFS? If yes, you'll need to add APFS.efi to /EFI/Clover/drivers64UEFI Link to comment Share on other sites More sharing options...

barnum Posted June 14, 2018 Author Share Posted June 14, 2018 Hi All, now everything is up, I try the new bootpack, but it was not working. So I recreate all the kernel cache then I saw that I have an old path for RTC in the /S/L/E directory when I rebuild the cache I delete it and rebuild the cache again and I remove the prelinked kernel then reboot et voila, it work.
