        Im using iMac 21-inch 2015 late.


        After installed Catalina, my machine got incredibly slow and finally, after few hours after installed Catalina, my machine went to reboot and then five languages screen, reboot and then five languages screen... over and over again.


        I tried verbose safe mode but I only got endless errors: fusions_wbc_pop_head 1789 obj_modified wbc failed: 22 invalid argument.


        I’ve tried to reset my Fusion Drive with diskutil in recovery mode or reinstall my OS but the machine goes to endless reboot again.
