While the bug was fixed just days after it was found, it raised questions about Apple's quality control and only amplified fears that Leopard had been pushed out of the door too soon. Although nothing as nasty has shown up in Leopard since then, the data-loss issue put off some buyers, and in fact, a lot of Mac fans weighed in on online forums and in blogs, saying they would wait a few weeks before spending their US$129 on the operating system.

Less serious were the complaints about changes to the operating system's user interface, which offered a more unified look by ditching the "brushed metal" look used in Tiger. Coming under fire were the changes to the Dock and modifications to the Finder, including a new way to navigate the Mac's file system called Cover Flow. While this new feature allowed for iTunes/ iPhone-like album browsing through files in the Finder, many fans in online forums dismissed it as needless eye candy, while others debated its merits. Even something as minor as the newly transparent menu bar divided Mac users.

Whether you were happy with these interface changes seemed to depend on whether you were a longtime Macintosh user or a recent convert. Generally, long-time users found the new animations and graphics superfluous; new users, by contrast, liked them and found the animations useful.

No taste for eye candy

Complaints seemed loudest about the more graphic-intensive Dock, especially its new reflective quality and 3-D appearance; those complaining preferred the older two-dimensional look. Resourceful Mac fans soon devised ways to change the Dock's appearance -- some involving command-line access, others involving more extensive system changes using third-party software.

While the Dock's appearance could be changed, a new feature called Stacks couldn't Tiger users had grown accustomed to a Dock that showed folder contents as hierarchal, text-based lists, which allowed them to traverse folders and files without relying on the Finder. But Leopard's Stacks displayed icons in either a grid or as an arching fan of icons, depending on where the Dock was on the screen.

If you had a folder with 10 items or less and your Dock was located on the bottom of the screen, icons arched out from a folder when you clicked on it. If you had more than 10 items in that folder, however, you got icons lined up in a grid. And if the Dock was located along one side of the screen, all you saw was a grid.

That's not exactly the model of user-interface consistency that Mac users had come to expect from Apple, to be sure. Adding to the unpredictability: A folder's Dock icon changes to reflect the most recent file added, annoying users accustomed to a consistent Dock interface.

While these seem like minor issues, devoted Mac users take these things very seriously. Apple apparently did so as well -- when the second update for Leopard was released in February, it allowed users to display folder items as they had in Tiger, using hierarchical menus or icons. Right-clicking on a Dock icon now opens a customizable pop-up menu that allows users to choose among the various options, even allowing each folder to have its own setting.

That same update offered a "fix" for Apple's new translucent menu bar at the top of the screen. Until Leopard, it had been white; with Leopard, it looked more like frosted glass. The new look allowed desktop pictures to show through, potentially making menu commands harder to read -- something that was never an issue when the menu bar was a solid white.

As with the Dock, innovative users quickly devised ways to make the menu bar appear to be a solid color, while others tried desktop pictures with a white strip across the top. With the 10.5.2 release, Apple added an option to the operating system that allows users to toggle the menu bar between translucent and solid. (It's located in the Desktop & Screen Saver System Preference.)
