I sent in my package as requested 10 days ago but have not heard back. Please advise.
Hello,
unfortunately your Mac falls to the list of machines where "MacOS fails to load kernel extension with 'no reason'"; aside from trying to restart MacOS and hoping it will start working again, there is little we can do for you.
We apologise for the issue; unfortunately on Mojave it does not even make sense to gather more diagnostic data and report it to Apple as they have told us we should recommend users to update to newer OS with similar problem. We will improve our messaging to provide more information in the future.
Kind regards,
Ondrej Kolacek
