Quark's Gavin Drake told us: "We're not anticipating a large effort to support QuarkXPress 10 running on OS X Mavericks and expect support within 90 days of the new OS's availability. We've done a lot of work modernising QuarkXPress 10 inside and out, which will enable us to more immediately take advantage of new Mac OS X features. It's a little early to talk specifics but as an example it's likely we'll get to leverage the multi-display support through our new full screen functionality and our ePub export will be certified for iBooks on OS X."
It appears that it won't be an easy ride for everyone though. One of Apple's new Developer Tools uses Automatic Reference Counting (ARC) for Objective-C -- this lets the compiler take care of memory management. It should lead to a simplified development process while reducing crashes and memory leaks, according to Apple's documentation. One developer referred to this technology, explaining that they had migrated applications to 'garbage collected memory management' in OS X 10.6, and expects to have to do a similar migration to ARC.
However, this isn't a bad thing, according to Public Space's Frank Reiff. He noted that: "ARC is clearly better technology, so it will be a benefit to both me and my users anyway. I should really have done this already and Apple have supplied a lot of tool support for migrating, so I don't anticipate much of a problem."
There are still some features missing, as far as some developers are concerned. MacAce's Gary Hall said: "I'm still waiting for native FTP / SFTP and better WebDav support - something that consumes a huge amount of resources overcoming Mac OS's current limitations in our MacMate product."
Where next for Mac OS X
Hall had an interesting insight about where OS X is headed: "I always see a "point-nine" release as an indication of where the next major release is going. Tim Cook and his team on stage mentioned 'the next ten years'a few times so I think both iOS7 and Mavericks are a stepping stone to something very very big next year: Mac OS XI."
He added: "Apple have shown that they are not afraid to completely redesign everything - which I'm sure is Jony Ive's next job starting next week."
