Home Forums Mac Software Mac Operating Systems Catalina, 32 bits, APFS and DiskWarrior

If you absolutely need to run DiskWarrior on a APFS drive, the only thing you can do is use Carbon Copy Cloner to clone the drive to an external drive. Then boot from the clone and erase the internal APFS drive and clone the external drive back to it.

I don't know if you can use Disk Utility from an external drive to change the file system of the internal drive, but if you can, then you could use DiskWarrior on the interal drive, too. That's what I did on my 10.13.6 set up.

Or, wait for the next release of DiskWarrior that they say is on the way. I'm sure it will come at a cost, rather than just a free update.
