So are those companies Steinberg’s role models or the former?
In that case you can state so in your public announcement: “Sorry, but we’re waiting for a specific fix or fixes from Apple”. Unless this is all hypothetical, and is not the case here.
And never wait until the OFFICIAL RELEASE to begin testing, fixing bugs and giving feedback to Apple, when there are the bloody DEVELOPER releases. This recommendation will ALSO most likely remain valid for the OS upgrades to come.
Also it’s best if third-party software companies don’t dictate what people can and cannot do with their PCs and OS updates. Because “wait until the dust has settled” can also mean “we’re short staffed or lazy and we can’t be bothered, halt your upgrading until we get our act together”.
