During CEO Steve Jobs’ WWDC keynote presentation, “Apple elected to keep the majority of the details of its upcoming Leopard release of OS X (version 10.5) secret, sharing them only with developers covered by Apple’s strictly enforced non-disclosure agreement. However, Apple did offer some intriguing details,” Tom Yager reports for InfoWorld.
Yager reports, “Leopard will be a 64-bit operating system, but with a powerful twist: It will permit the blending of 32-bt and 64-bit code at the executable, object code and device driver levels. Microsoft’s 64-bit editions of Windows XP and Windows 2003 Server require the use of drivers specifically rewritten for 64-bit use. Apple’s approach avoids second-class customers with 32-bit Macs while allowing developers to take full advantage of the features unique to Core Microarchitecture. Apple carried 64-bit engineering from the OS kernel through the GUI and 3-D layers, creating incredible performance potential for visuals, and for core computing tasks that are slowed by rich graphical interfaces.”
Yager reports, “Another standout among Leopard’s features is Time Machine, a highly accessible approach to file system snapshots for rapid recovery of deleted or unintentionally altered files. Like Windows’ Volume Shadow Copy, Time Machine tracks all of the file and directory changes that occur between snapshots. Users can specify a point in time and see the file system from any point in the file hierarchy as it existed at that time, or the time of the nearest snapshot. As is typical for Apple, the user interface for Time Machine is visually stunning and extraordinarily functional. When a user selects a folder, an Address Book card or any other Time Machine-tracked entity and presses the Time Machine hot key, snapshots are shown in a stack of overlapping windows. A GUI timeline at the edge of the screen lets the user scroll through time, and the user can skip back to the most recent snapshot whose contents differ from the present.”
“Time Machine goes a step beyond point-in-time recovery with its ability to save snapshots on external storage. A Mac client with a USB or FireWire external hard drive can use Time Machine to maintain automatic, invisible incremental backups of modified files. Using this facility, a Mac that requires an internal drive replacement or gets a disk upgrade–say, a switch from a single drive to software RAID–can be restored using that external drive. Time Machine data can also be managed on client systems’ behalf by a Time Machine service that will be standard in OS X Server Leopard,” Yager reports.
Yager reports, “Apple demonstrated [just] ten Leopard features in all… Clearly, Apple’s been busy. It’s hard to believe that Leopard will ship next spring, but Apple aims to ruin Vista’s chance of gaining early traction. During the keynote, Apple convincingly demonstrated several specific Vista features and look and feel elements that seemed copied directly from OS X. While Apple is keeping most of Leopard’s details to itself, the message is clear: By the time Vista and Longhorn Server catch OS X Tiger, Apple will have pushed the goalposts all the way out to the parking lot.”
