The main features of Panther included a refined Aqua theme, Exposé, Fast user switching, and a new Finder. Panther also included Safari as its default browser, as a change from Internet Explorer in Jaguar.

System requirements

Panther's system requirements are:^[4]

• PowerPC G3, G4, or G5 processor (at least 233 MHz)
• Built-in USB
• At least 128 MB of RAM (256 MB recommended, minimum of 96 MB supported unofficially)
• At least 1.5 GB of available hard disk space
• CD drive
• Internet access requires a compatible service provider; iDisk requires a .Mac account

Video conferencing requires:

• 333 MHz or faster PowerPC G3, G4, or G5 processor
• Broadband internet access (100 kbit/s or faster)
• Compatible FireWire DV camera or web camera

Because a New World ROM was required for Mac OS X Panther, certain older computers (such as beige Power Mac G3s and 'Wall Street' PowerBook G3s) were unable to run Panther by default. Third-party software (such as XPostFacto) can, however, override checks made during the install process; otherwise, installation or upgrades from Jaguar fails on these older machines.

Panther still fully supported the Classic environment for running older Mac OS 9 applications, but made Classic application windows double-buffered, interfering with some applications written to draw directly to screen.

New and changed features

Apple advertised that Mac OS X Panther had over 150 new features, including:

• Finder was updated with a brushed-metal interface, and given a new live search engine, a customizable Sidebar, secure deletion, colored labels (resurrected from classic Mac OS^[5]) in the filesystem and Zip support built in. The Finder icon was also changed.
• Fast user switching was introduced; it allows a user to remain logged in while another user logs in, and supports quickly switching among several sessions.
• Exposé is a new feature that helps the user manage windows by showing them all as thumbnails.
• TextEdit is now compatible with Microsoft Word (.doc) documents.
• Xcode developer tools have faster compile times with gcc 3.3.
• Preview has increased speed of PDF rendering.^[6]
• QuickTime now supports the Pixlet high-definition video codec.^[6]
• Font Book is a font manager which simplifies viewing character maps, and adding new fonts that can be used systemwide.^[6] The app also allows the user to organize fonts into collections.
• FileVault is a new app that has on-the-fly encryption and decryption of a user's home folder.^[6]
• iChat AV now has built-in audio- and video conferencing.^[6]
• X11: Compatibility^[6] for applications based on the X Window System, commonly used for UNIX applications, is available through an optional install, found in the install disk. Mac OS X Panther is the first macOS version to officially support X11. It utilizes Quartz to provide hardware accelerated graphics^[7] and is based on the XFree86 implementation^[8] of X Window System.
• Safari is a new web browser that was developed to replace Internet Explorer for Mac when the contract between Apple and Microsoft ended, although Internet Explorer for Mac was still available. Safari 1.0 was included in an update in Jaguar but was used as the default browser^[3] in Panther.
• Microsoft Windows interoperability improvements were made, including out-of-the-box support for Active Directory and SecurID-based VPNs.
• Built-in fax support.^[9]: 1 Sending a fax can be done using the native Print dialog.^[9]: 2 To receive faxes, users must pre-configure in System Preferences on how the system should handle an incoming fax, with options^[9]: 4 including selecting a folder to save the incoming faxes, to automatically email to an address or to print via a selected printer, upon receiving of the fax.
• Secure Empty Trash is a feature added in Mac OS X Panther^[10] to ensure, through the use of data erasure techniques, that deleted files cannot be recovered.^[11]
• Panther added support for WPA and WPA2 level security on wireless networks (with the AirPort 4.2 software update).
