Road to Mac OS X Leopard: Finder 10.5The Finder in Mac OS X has long been reviled as the most glaring problem in the system, earning it the "Fix the F-ing Finder" meme. Apple has significantly updated the Finder for Mac OS X 10.5 Leopard, introducing some things old, some things new, some things borrowed, and, well, the icon is still blue. Here's a look at what's new.
The Finder's Origins
The Finder is as old as the Macintosh. In the earliest versions of the Mac's System Software, the Finder was a simple file utility that ran as the default application when the system started. It allowed users to organize and rename their documents, and delete them by dragging icons to the trash.
In order to deliver the original Mac at a much lower price point than the Lisa, its more expensive older sister, Apple reduced the amount of memory it used, forcing the Mac to drop the Lisa's multitasking support. Because the Mac System Software could only run one application at a time, the Finder would shutdown whenever another application was launched, and then restart when that application was quit.
In order to allow multiple apps to run together and quickly move between them, Apple's Andy Hertzfeld released Switcher, which loaded multiple apps into memory and allowed the user to select a desired app with a key press. As applications switched, the new active application would slide in horizontally.
In the late 80s, Finder 6.0 was delivered with MultiFinder, which shipped with Mac System 5 and System 6. After activating MultiFinder, the system could perform the task of Switcher onscreen, allowing users to have multiple applications running together on top of the Finder desktop, and operate between them seamlessly.
System 7 built this function in as the default option, and continued to add services that built upon the idea of having multiple windows active at once, including drag and drop support between applications. By the late 90s, Apple renamed the latest version of System 7 to Mac OS 7.6, and then released successive versions under the names Mac OS 8 and Mac OS 9. Despite adding new features and optimizations, the Finder didn't change dramatically from its late 80s design, although a variety of shareware apps were tacked on the side.
The Mac OS X Finder
The release of Mac OS X carried over the idea of the Finder, but was built upon a completely different foundation. Rather than being a application that shared the screen and the processor with other running apps in cooperation, the new Finder was a fully preemptively multitasked application running on top of a Unix foundation.
That meant that a rogue application could be force quit without taking down the entire system, and that the Finder itself could be killed and restarted without disrupting or destabilizing the operating environment. Earlier Mac OS versions could attempt to kill a frozen application, but it would frequently lock up the system entirely. Windows 95/98/Me promised to deliver preemptive multitasking, but the instability of the underlying system similarly meant that a crashing application would frequently take down the entire Windows session with an "illegal operation" error.
For Mac OS X, Apple worked to both maintain portions of the Finder legacy and to rethink its interface features as part of the new Aqua user interface. Rather that being a single, monolithic application that handled everything, the new Mac OS X desktop came to include a series of applications that worked together to create the Finder and desktop experience.
- The new Finder handled the desktop and Finder windows.
- The new Dock acted as a program launcher and a holding tray for files and open windows.
- The Menu Bar and its Menu Extra icons on the right were managed by the SystemUIServer application.
- Various other faceless system applications associated with the Finder are handled by other helper apps.
The Finder look from 10.0 to 10.2 (below left) reflected the translucent plastics of the iMac and incorporated a Toolbar shelf and column view borrowed from NeXTSTEP (below right).
Fixing the Finder
Compared to the classic Mac OS Finder, the new Mac OS X Finder felt slow and even clumsy, and lacked some of the features of Mac OS 9. Because Apple had rewritten the Finder using Carbon in order to prove to third party developers that Mac OS X could run their existing classic applications with minimal work, many assumed that simply rewriting the Finder using the Cocoa frameworks would solve all of its problems.
Others complained that the new Finder broke convention with the old single view, spatial paradigm of the classic Mac Finder. They found it simply too confusing because it would allow users to open multiple windows of the same folder using different view settings (icon and column view, for example).
In addition to complaints about performance and preferences, the Mac OS X Finder simply failed to demonstrate new innovation in line with other developments Apple had introduced. This was particularly evident as iTunes, Safari, and other Apple apps progressed rapidly, leaving the Panther/Tiger Finder looking oddly out of place. It really hadn't changed much in terms of features over earlier versions.
John Siracusa of Ars Technica, John Gruber of Daring Fireball, and Daniel Eran Dilger of Roughly Drafted have each offered ideas on fixing the Finder over the last half decade: About the Finder...; That Finder Thing; and How to Fix the Finder: Faster, Prettier, Smarter.
The Leopard Finder
Last year, Apple unveiled the new design for the Finder in Leopard. Some of the features associated or deeply integrated with the Finder really belong to other applications or services, including the Dock, Spotlight, Spaces, Time Machine, and Quick Look. Some of these features will be considered in a separate article.
The new Finder 10.5 drops the brushed metal look introduced in 2003's Panther 10.3 (above), and instead adopts the new unified aluminum appearance common to all apps running in Leopard. It borrows obvious elements from iTunes, including its sidebar. The Library, Shared, and Playlists of iTunes become the Finders' Devices, Shared, Places, and Search folders (below).
Devices lists internal and locally connected drives, optical and other removable disks, and the local .Mac iDisk mirror, if configured.
Shared lists a Bonjour browsing of file servers on the local network, along with the Back to My Mac feature and other connected servers. Back to My Mac is a new feature that allows you to register your home system with .Mac, and seamlessly access file shares, printers, and other shared items remotely over the Internet. Connect from anywhere, and all your shared resources at home are available from the Finder's sidebar.
The Bonjour browsing makes it much easier for non-technical users to share files. Taking the place of the old Chooser or browsing the Connect to Server or the even more odd Network source in the existing Finder, the new list of Shared items works identically to how iTunes or iPhoto browse the local network to find possible shares and then present them for attachment.
Clicking on a shared system presents the shares that system is serving, allows you to log in, and then mounts the server as a drive. Mounted shares sport an eject button, allowing you to unmount any file shares directly from the sidebar.
Places lists whatever folders the user desires to put there; by default it lists the user's home directory folders, just as the previous Finder did. It uses the same "drag out to poof" Dock-like method for removing items; new items can be added by dragging in a folder between existing items. Dragging items to the folders will copy items into the folder.
Search For folders make queries available in Finder windows just like iTunes' Smart Playlists. By default, there are three searches the bring up files created or modified Today, Yesterday, or Last Week. Three more examples provide a starting point and indicate how to set up smart searches: All Movies, All Images, All Documents. The New Smart Folder command from the Edit menu is used to create a new folder, which can then be dragged into the Finder sidebar.
