Daring Fireball: Mountain Lion
And then the reveal: Mac OS X — sorry, OS X — is going on an iOS-esque one-major-update-per-year development schedule. This year’s update is scheduled for release in the summer, and is ready now for a developer preview release. Its name is Mountain Lion.1
Mountain Lion is the next iteration of Mac OS X. And while there are some changes since the original Lion was released just this past Summer, they are more like further improvements than real changes. I say this in part due to the concentration on aligning the OS X apps with iOS apps for small things like using the same name:
iCal versus Calendar
iChat versus Messages
Address book versus Contacts
Reminders versus Notes
Under the facial, superficial level more of the Carbonized libraries and apps are being factored out and being given full Cocoa libraries and app equivalents where possible. But one of the bigger changes, one that’s been slipping since the release of Mac OS X 10.7 is the use of ‘Sand-boxing’ as a security measure for Apps. The sand-box would be implemented by the Developers to adhere to strict rules set forth by Apple. Apps wouldn’t be allowed to do certain things anymore like writing to an external Filesystem, meaning saving or writing out to a USB drive without special privileges being asked for. Seems trivial at first but on the level of a day to day user of a given App it might break it altogether. I’m thinking of iMovie as an example where you can specify you want new Video clips saved into an Event Folder kept on an external hard drive. Will iMovie need to be re-written in order to work on Mountain Lion? Will sand-boxing hurt other Apple iApps as well?
Then there is the matter of ‘GateKeeper’ which is another OS mechanism to limit trust based on who the developer. Apple will issue security certificates to registered developers who post their software through the App Store, but independents who sell direct can also register for these certs as well, thus establishing a chain of trust from the developer to Apple to the OS X user. From that point you can choose to trust either just App store certified apps, independent developers who are Apple certified or unknown, uncertified apps. Depending on your needs the security level can be chosen according to which type of software you use. some people are big on free software which is the least likely to have a certification, but still may be more trustworthy than even the most ‘certified’ of AppStore software (I’m thinking emacs as an example). So sandboxes, gatekeepers all conspire to funnel developers into the desktop OS and thus make it much harder for developers of malware to infect Apple OS X computers.
These changes should be fully ready for consumption upon release of the OS in July. But as I mentioned sandboxing has been rolled back no less than two times so far. First roll-back occurred in November. The most recent rollback was here in February. The next target date for sandboxing is in June and should get all the Apple developers to get on board prior to the release of Mountain Lion the following month, in July. This reminds me a bit of the flexibility Apple had to show in the face of widespread criticism and active resistance to the Final Cut Pro X release last June. Apple had to scramble for a time to address concerns of bugs and stability under Mac OS X 10.7 (the previous Snow Leopard release seemed to work better for some who wrote on Apple support discussion forums). Apple quickly came up with an alternate route for dissatisfied customers who demanded satisfaction by giving copies of Final Cut Pro Studio 7 (with just the Final Cut Pro app included) to people who called up their support lines asking to substitute the older version of the software for a recent purchase of FCP X. Flexibility like this seems to be more frequent going forward which is great to see Apple’s willingness to adapt to an adverse situation of their own creation. We’ll see how this migration goes come July.
