I wrote this command for testing pkg health:
pkgutil --payload-files Spine.pkg
And it prints a couple of files, but at the end it shows this error:
Could not list files: The operation couldn’t be completed. cpio read error: bad file format
So there is. A corrupted file! Sorry guys! I downloaded the installation again and it works 💃🏻🕺🏿
Thanks @Misaki for the support!
