Yesterday, when I was trying to install Windows 10 on my Mac then suddenly the installation error occurs and the process stopped and showing apple error 4013. I don't understand why this happened. My system got corrupted and now I am not able to understand the actual issue and how can I resolve the issue.
Apple error 4013, generally implies a communication problem between the devices somewhere. USB connection, the physical drive connection, etc. etc.. Run a hardware test on your Mac. <https://support.apple.com/en-gb/guide/mac-help/mh35727/mac> Were you using an external drive?.
