Just adding a + one from me. Apple are pushing out their loyal pro (audio and video) users though continual dropping of backward support like this and numerous other significant core features. It's no longer the case that Apple are the only player in these domains. We can jump to alternate platforms easily and cheaply. As Apple drops pro features they risks loosing vital trickle down capabilities that enrich their mass market product sets. A good example is Logic to Garage Band etc. The same will happen with their pro compute products. If they don't have the compatibility or the following who's going to buy these expansive products? They risk becoming just another consumer company. We've put up with the lack of I/O, upgradeability, expensive hardwired resources (that cost an order of magnitude above OEM alternatives), deprecated support for not very old hardware, deprecated core components (like firewire), lack of 32bit support (that is a nightmare when you need to open older client files that use old 32bit plugins) etc etc. I'm also resist a long rant on challenges with older media access (like floppy, SCSI, CDROM especially in alternate formats like sampler images etc). Even Logic not supporting older project file versions (WTF? That is totally unacceptable - and yes I am aware you can import some items but come on - this is just lazy). How many times are we expected to just wear this in the name of "progress". Personally I run multiple platforms/images with various OS and hardware combinations - just so I can load my historical sessions, projects and media. Windows is far more forgiving with backwards support and broad compatibility. APPLE Please listen to your community. We are begging you to consider the impact of dropping backward support and please consult with us. You can start with reinstating Firewire support. PLEASE
