LogicL1,
Firstly, I take your points well... What you are saying has been said many, many times over by many people here and elsewhere, including myself. Apple's 'secrecy' policy is, imho.. very odd to say the least and extremely frustrating for us users... but it is what it is... and has been for so many years now... that I have sort of got used to it. I don't care for it.. but I have accepted it's just how Apple works.
Secondly, I am not an employee in any way of Apples. I happen to have several very good contacts within Apple's Development and Engineering teams, that I have been lucky to establish over the years.. along with several very well known 3rd party software and hardware Developers.. and several well connected clients.. thanks to my work with various Studios around the world.. but thats about it... and even with such contacts, trying to get hard facts out of Apple, that one can publish... about any given issue, current or past, can be nigh on impossible at times until such time as it is deemed by Apple to make such knowledge public.
Next, as I and others have said many times in the past about this issue or any other.... Don't be surprised if the majority of CSRs and first/second level tech support staff know nothing about certain issues because in fact, they simply don't know as no one will have told them... until such time as the information is made officially public by Apple.. Those that do know, as others have commented here and else where, are actual Logic Users themselves or have just been dealing with the current issue themselves and so they have become aware.. rather than having been told officially by Apple. There is an Engineering Team notice about this in the CSR database.. but that doesn't mean any of the CSRs are aware of it's presence at this time... and there is no current solution as part of that notice. If the CSRs follow their 'scripts' in troubleshooting such an Audio issue, it will lead them down the road to "Bad. incompatible.. or incorrectly installed 3rd party Audio/midi drivers" because typically in the past, that is what would cause such symptoms as are being reported by those with the 2013 iMac FD / Audio issue... so that is what the CSRs deem the problem to be... and so thats why they try and troubleshoot in the way they do.. (Check for new drivers.. uninstall 3rd party plugins.. reinstall Logic.. reinstall OS X... Contact your Audio Interface's Developers and so on...)
Apple even keeps secrets from Apple... as bizarre as that sounds.. to the uninitiated...
As a good recent example... No one outside of the Logic Dev team, a few Upper management people at Apple, a small group of 'selected' hardware/software developers... and the small internal and external Logic testing team.. knew anything about Logic Pro X until it was announced and released... and even that small group were heavily bound legally by various NDAs designed to keep their 'mouths firmly shut' about it's development... until again, the news was made public, officially by Apple.
CSRs didn't know.. Sales staff didn't know... Most of the OS X Dev team didn't know... None of the 'Geniuses' apparently knew ahead of time... and certainly no one here or on any other similar website knew... unless they happen to be a member of that small external test team or are one of the 'select' hardware/software devs... and then of course, they couldn't say anything anyhow because of the NDAs they were bound by.
A few Journalists and Studio owners were invited to and shown 'demos' of LPX a few weeks prior to it's release but the 'demos' were carefully 'managed' and again, those attending had to sign very strict NDAs about what they saw and heard... and could only speak publically about LPX, once it was officially announced and released by Apple.
It is literally, as strange as it appears and as unlikely as it seems....but it is how Apple 'works' and has done so, as I said, for so many years now... Just get used to it and don't expect it to change anytime soon.
So finally, what i post here, comes from my various sources...or hearing it 'first hand' myself.... or based on my own tests I run at my own studio.. using my test bed Macs that i keep for just such purposes..... and I do my best to ensure it is accurate by cross checking everything with other sources first before posting... but as I always try and get across.. please take such info 'as is'... because things can and do change with Apple and until something is announced 'officlally' by Apple, you can never be 100% sure about anything...
Cheers..
Nigel
