About

Mac OS X Developer Preview 4 is the fourth and final Developer Preview of Mac OS X Public Beta. This build was demonstrated and distributed at the Apple Worldwide Developers Conference on 15 May 2000.^[1]

This build removes the Blue Box emulator. And instead, Classic now requires a Mac OS 9 volume to be present.

New features and changes[edit | edit source]

Setup[edit | edit source]

The preinstallation environment was updated to Mac OS 9.0.4, and the Setup has been slightly updated.

Finder[edit | edit source]

The Finder has been slightly updated in this Developer Preview, with the Search toolbar being removed. Instead, three buttons were added to change between the view modes.

User interface[edit | edit source]

This build includes updates to the Aqua theme, making it resemble more to the Public Beta.
The Dock has been heavily revamped from Developer Preview 3, and now is more closer to the Public Beta. Some of these changes includes removing the application backgrounds and using a rectangular base to replace these backgrounds. The Dock is also translucent much like the menus and inactive applications. Items from the dock can also be removed, utilizing the animation of the item disappearing in a puff of smoke. When minimizing an application, the application now slides to the dock, and when maximized, slides back to the position it was originally minimized in. To show that a program is open, three dots are placed under the program's icon.
Dock magnification effects are also enabled by default; this would be disabled by default in later builds and versions.
The application icon that replaced the Apple logo in Developer Preview 2 and before is now gone, and replaced with the name of the running application.
A country flag is included to the right of the "Help" of the menu bar so the user can quickly change languages.
DP4 has been added under the Mac OS X text in About this Mac.
The Login screen has been slightly updated, the Restart and Shutdown icons no longer have colors, and the color of the Login icon was changed from green to blue.

Miscellaneous[edit | edit source]

Internet Explorer 5.1b1 has been added.

Bugs[edit | edit source]

Installation[edit | edit source]

On QEMU, this build has a bug where the CD-ROM driver doesn't work properly, causing the boot to hang. To install this build on QEMU, the installation media has to be booted from a hard drive media and not from the CD-ROM drive.
