Import hand's on pen test 1 kali linux on mac os

Hello, I cannot import kali linux into my virtualbox on mac os, I get this error. Why?!

There are multiple reasons you might get this error. Check your storage, see if you have enough space or not. See if the downloaded kali linux is corrupted or not. Try re-downloading it again. Also, there is a weird bug in macOS about the sound driver. Try disabling the sound driver while importing the ova.

All right thx, I’ll try with a new external hard drive first then I will try to disable this driver if it’s still not working.
