The new file-system alone is a very sufficient reason to do a new OS release. They're talking about it supporting native encryption (so probably getting rid of the whole "File Vault" thing you have now, where you have to manually run it and let it churn through a preparation process to enable encryption support).
But ever since Apple started bundling some of the applications with the OS, it puts it in the situation where updates to those apps require a new OS version, to keep everything consistent. Not trying to argue whether or not this was the "best" way to handle all of that ... but just saying that's where it leaves us today. As it stands now, a developer can assume a user has, say, "Photos" installed just by verifying the OS X release is El Capitan or later. That's something they'd want to know if they're trying to make your photo library accessible seamlessly inside a "picker" window in their own program -- because iPhoto required a different method of accessing it.
I feel that alot of these features could be implemented in a simple update to El Capitan.
I see no need in releasing a whole new version of an OS just to add these features, except the new Apple filesystem.
[doublepost=1466187908][/doublepost]No disagreement they're still great computers today, but I sold my 2008 Mac Pro tower back in 2014 and didn't look back. I don't think it's any secret that Apple has *never* shown interest in you clinging to a machine they sold you 7 or 8 years ago. The "but it's a PROFESSIONAL" machine doesn't really hold much water either, IMO. If you're truly using it for "commercial/pro" type work, it should still have more than paid for itself in the first year or two you used it. Otherwise, maybe the problem is not the computer but the user?
Since Apple sells both the hardware AND the operating system, the whole business model revolves around you upgrading both portions in regular cycles. If you're not willing or interested in doing so, then fine. You're left with a computer that's still as good as it ever was at running all of the software and all of the operating systems up through the date the last OS was released. For many people, that's just fine. (I know a graphics designer who makes a living doing commercial artwork, such as the sides of boxes or cans of products shipping to the U.S. from overseas. It wasn't that long ago, he was still using only "vintage" Macs running MacOS 9.1. He's an older guy and would rather retire than learn everything involved in getting current with the latest versions of apps like Photoshop, not to mention OS X itself. As long as he can run the old, outdated versions of all the expensive design software he bought long ago, and he has a good enough Internet broadband connection to get his work uploaded to the people who pay him, he's good.)
I didn't see that thank you. I'm still upset Apple basically dropped support of their 2008 and 2009 professional workstations. Those are still powerful computers today. It's very disappointing.
