I am outraged and will try to keep it politically correct. Really.
First I am recommended to uninstall and reinstall Parallels because it wouldn't start up because of a "driver problem", now, AFTER uninstalling I am told it is not compatible wit macOS Sierra anymore?
What kind of policy is this? I have BOUGHT this software! And it wasn't cheap to claim it's functionality for only two years!
As a student I cannot afford to buy the same software every other two years just because it has gone "incompatible"! Every other piece of software works perfectly fine, and if it doesn't there's a free update within days.
I get it, Parallels integrates deeper into the system, but ist not like you're reinventing the wheel, you're adjusting to updated apis, like everyone else does.
This is how you get people to pirate software. Those will never suffer from limitations, like your legal customers do.
I really, REALLY, regret buying this software. If theres no solution you can provide to this, I will never again.
Thanks for nothing,
a disappointed customer.
