And to answer the question of "will the old Pyware versions run on it" here is the answer:



It's a circular link. So if you click the link in the above Facebook post, you just come back here.

Once you upgrade, though, download the legacy Java package here: https://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US

Once it's installed, you should be good to go for any of the old Pyware versions.

Now for the bad news: you are venturing into unsupported territory. This can break at any time for any reason and there isn't much that can be done about it. Apple has made it clear that the legacy Java will be 100% unsupported from now on. That being said, there might not be something Pyware can fix down the road due to this unsupported territory we are in.

For the immediate future, though, it installs and runs as well as it did under Sierra…at least for now.
