Microsoft Internet Explorer 3.01 for Macintosh

Thank you for choosing Microsoft Internet Explorer for Macintosh. Although Internet Explorer 3.01 has dozens of new features, by the time you read this, there may already be a new version of Internet Explorer, so please check out periodically for updates.

Microsoft Internet Explorer is a World Wide Web (WWW) browser for the Macintosh. The WWW is the fastest growing component of the Internet today. In order to use a WWW browser, you will need a modem or network access, access to the Internet, and software that enables your computer to communicate with the Internet.

Microsoft Internet Mail and News, our small and fast e-mail client, and Microsoft Personal Web Server, which turns any Mac into a Web serving solution are not included in this installer. You can visit to download these products.

Registering Internet Explorer

We've made it even easier for you to register Internet Explorer 3.01. The first time you open Internet Explorer, you will automatically visit our online registration site. Remember that this only occurs the first time you open Internet Explorer after installation. The next time you open Internet Explorer, you will visit your default home page. For more information, see the License Agreement.

New Features

Version 3.01 of Internet Explorer represents a surprisingly large number of new features, so be sure to take a look at the following:


JavaScript is the easiest and fastest way for Web authors to add interactivity to a Web site. Unlike Java, which is based on separate software components, JavaScript is a scripting language whose programs are embedded right in the HTML. You can use the Preferences dialog box to turn scripting on and off.

Choose your Java virtual machine

Settings in the Preferences dialog box give you greater control over the use of Java:

  • You can choose which Java virtual machine you would like to use: Microsoft VM or Microsoft JIT. If Apple MRJ is already installed on your machine, you can choose it.
  • You can specify whether a warning should be displayed if there are errors in the Java applet or whether the browser should save the output text from the Java applet.

Downloading files

The Download File command in the File menu lets you download files from the Internet while you continue to browse other Web pages. Once you have typed the URL of the file you want to download, the Download Manager will open and give you information on the status, size, and download time of the file. The Download Manager is also available from the File menu and it keeps a history of the files you have downloaded. You can double-click the downloaded item in the Download Manager for more information.

Internet Explorer now supports folder downloads from FTP and Gopher sites. Drag and drop the folder to the Finder to download the contents of the folder. You can also press and hold down the mouse button over an item on the Web page, and then choose Download Link to Disk from the context menu.

Enhanced download options include automatically decoding BinHex and MacBinary files while the file is being downloaded.

Note: For information on configuring your browser to process MacBinary files, see Knowledge Base article 24629: "Microsoft Internet Explorer: Configuring For MacBinary"

Manage site passwords and user names

The Site Passwords page in the Preferences dialog box maintains a list of the user names and passwords you have used to access a site. Now, you can change access information without going to the site.

Receive updates to your favorite pages

When you mark favorite pages as subscribed pages, Internet Explorer will monitor those sites and notify you, when and if a subscribed page changes. To select how often you want Internet Explorer to look for changes, and how you want to be notified of changes, choose Subscription Options from the Favorites menu.

Note: This is a subset of the Subscription functionality that will be included in the Internet Explorer 4.0 platform preview.

Improved favorites

You can sort favorite items, rename the path, and resize the columns in the favorites list. In addition, you can turn a subscription to a favorite page on and off by clicking in the Subscriptions column (the left most column in the Favorites window). To change subscription information for a particular item, double-click the subscriptions icon located beside the favorite item.

Manage cookies

A cookie is a small piece of information that a Web site downloads on your hard disk for future reference. For example, a cookie might be used to store a customized view of a Web site or ensure that you never see the same advertisement twice. Settings in the Internet Explorer Preferences dialog box let you control the download of cookies. For example, you can choose to always accept cookies or you can choose to always display an alert when a Web site wants to download cookies.


Internet Explorer has made searching the Internet even easier with the Autosearch feature. Simply type go or ? and the topic you'd like to search for in the Address Bar, and Yahoo! ( will search its databases for matching topics and display them for you. For example, type ? cooking to find all references to cooking in the Yahoo! database.

Fetch bookmarks

Do you have Fetch bookmarks? Now, you can import them into Internet Explorer. Drag and drop your Fetch bookmarks into the Favorites window of Internet Explorer.

Type ahead in the Address bar

Type an address into the Address bar and Internet Explorer can attempt to complete the address using the contents of your favorites and history lists. First, Internet Explorer will review the names and addresses in your favorites list, and then, if it doesn't find a match, it will review the names and addresses in your history list. For example, if you recently visited the Microsoft site at, you might need to type only the letters Mic or

before Internet Explorer displays the complete address for you.

You can turn off this option by choosing Preferences from the Edit menu, clicking the Browser Display under Web Browser, and then clearing the Auto-Complete Addresses check box.

Refreshing a Web page from the context menu

You can reload a Web page quickly by using the Refresh command from the context menu. This feature is especially useful when you want to refresh the contents of a file contained in a frame. Simplyclick inside the frame, hold down the mouse button, and choose Refresh from the context menu.

Preferences and Internet Config

Internet Explorer is now more closely integrated with Internet Config and works with the preferences file for Internet Config directly. You no longer have to select whether or not you want to use Internet Config. Any settings you change in the Internet Explorer Preferences dialog box automatically go to the Internet Config Preferences file. If you currently use the Internet Config application, you can continue to do so and the changes you make will automatically appear in Internet Explorer.

More preferences are now available from the Preferences dialog box to better customize your browsing experience. You can control animated GIFs, file downloads, Java VMs, proxies and other features.

ActiveX update

We now have a new version of the ActiveX SDK that supports ActiveX scripting. For more information on this feature, please go to the ActiveX SDK site at .

Known Issues

Installing from the CD

Internet Explorer Installer requires that the startup disk of your computer is a hard disk. You will get an error during installation if your startup disk is a CD ROM drive. If this occurs, restart your computer and then run the Internet Explorer installer.


You may not be able to view large Java applets on 8 MB machines when there is not enough system memory free. This occurs because the Java virtual machine is loaded and unloaded dynamically in the system memory. Memory is used only when you view pages with Java applications.

A 68K JIT is not available at this time. If you are a 68K user make sure that you choose the MSIE/MW VM or the Apple VM (if installed). Please visit for updates.


Microsoft Internet Explorer 3.01 for Macintosh has native ActiveX support, and does not require the use of a plug-in. The Microsoft ActiveX Plug-in included with this installer is for use with older versions of Internet Explorer or other browsers that use plug-ins and do not have native support for ActiveX.

Some Web pages may have ActiveX controls that do not support Mac OS. If this happens and you are unable to view the page, you can turn off viewing of ActiveX content. To do so, choose Preferences from the Edit menu, click Web Content under Web Browser, and then clear the Enable ActiveX check box.

Note: Please be aware that in this release, Internet Explorer cannot verify the integrity of ActiveX controls. Download and use ActiveX controls from trusted servers only.

Protocol helpers

You can use the Preferences dialog box to assign protocol helpers. When you do so, please note that the Use Current Application If Possible check box is turned on by default so that if Internet Explorer can handle the protocol, it will be used instead of the assigned helper. For example, if you have assigned Fetch as your current FTP (File Transfer Protocol) helper and have not cleared the Use Current Application If Possible check box, when you click an FTP link in Internet Explorer, Internet Explorer will be used to download the file, not Fetch.

If you do not want Internet Explorer to handle a protocol, be sure to clear the Use Current Application If Possible check box.

Real Player 4.0b1

The current beta version of the Real Player 4.0b1 installer may corrupt the Internet Preferences file, in which Internet Explorer stores its preferences. If this occurs, delete the Internet Preferences file (located in your Preferences folder inside your System folder). The next time you open Internet Explorer, a new Internet Preferences file will be created.

QuickTime and PowerPlug

If you have QuickTime installed, Internet Explorer requires that the QuickTime PowerPlug be installed in the Extensions folder in your System folder. QuickTime extensions are available for download from .

QuickTime and QuickDraw 3D

If you use the Extensions Manager to disable QuickTime and QuickDraw 3D, you need to remove the appropriate QuickTime and QuickDraw 3D libraries.


If you are using Internet Explorer to view VRML pages, you must have QuickDraw 3D version 1.5 or later installed. QuickDraw 3D is available for download from .

Internet Config File Mappings table

Internet Explorer maintains an internal list of viewers that tells it how to handle different types of documents. In this release, this list is exported and merged with the Internet Config File Mappings table. As a result, please consider the following:

  • Internet Explorer's list of viewers is indexed by the MIME types (Multimedia Internet Mail Extensions) of incoming documents. Since Internet Explorer cannot use a viewer without a MIME type, it will ignore them, but not delete or alter file mappings in Internet Config that do not contain a MIME type.
  • Internet Explorer maintains only one table entry per MIME type. If you have multiple file mappings in Internet Config with the same MIME type, Internet Explorer will use only the last setting in the table.
  • Internet Explorer adds a small amount of information to each file mapping in Internet Config to store its How to Handle setting. When you choose Use Explorer as a Viewer, Internet Explorer always attempts to handle the document type, regardless of the settings in Internet Config. Most file formats use the viewer specified in Internet Config, however, certain file formats like GIF and JPEG are handled by Internet Explorer regardless of your Internet Config setting.

Using Help

Internet Explorer Help is available from the Help (?) menu and will give you the information you need to use the powerful features of Internet Explorer.

    1. Click a topic area on the left to see a list of related procedures. To open the procedures in a separate window, press and hold on the topic area link and then choose Open Link from the context sensitive menu.

    2. Click Index to see the Index. Use the Index just as you would an index in a book.

Java Virtual Machine components for Internet Explorer 3.01

Microsoft Internet Explorer 3.01 Java support is based on the JManager interface as defined by Apple Computer, Inc. Internet Explorer has an open architecture that supports multiple Java Virtual Machines such as the Apple Java Virtual Machine, MSIE/MW VM, and MSIE/MW PPC_JIT VM.

To enable Java in Internet Explorer:

1. Choose Preferences from the Edit menu.

2. Click Java under Web Browser, and make sure the Enable Java check box is selected.

3. To change your VM, choose it from the Java Virtual Machine menu.

Java VM pop-up menu will be grayed out, if a Java VM is not installed on your machine. To install Java VM see the instructions in The Apple VM below.

The Apple VM

Internet Explorer uses the Apple Java Virtual Machine that comes with your system software. If not installed please install it from the Mac OS System Software CD or download and install it from .

The Microsoft Java VM

The Microsoft Java VM was jointly developed by Microsoft and Metrowerks and is available in two flavors: MSIE/MW VM and MSIE/MW PPC_JIT VM. You may use either the MSIE/MW VM or MSIE/MW PPC_JIT VM with Internet Explorer, but one may be better suited to your needs.

The Microsoft Java VM in not included in this version of the Internet Explorer Installer. The MSIE/MW VM can be downloaded from .Follow the instructions to install, and change Internet Explorer Preferences as noted above to choose from the different Java Virtual Machines.

The MSIE/MW VM is installed with Internet Explorer requires less memory and lets you debug Java applets. The MSIE/MW PPC_JIT VM includes technology known as a Just In Time (JIT) compiler. The JIT takes standard Java byte codes and compiles them into native PowerPC instructions. For computational applets, you will see a dramatic increase in speed. Graphics speed, however, will remain largely unaffected. The JIT VM does not support debugging and it requires more RAM because PowerPC code is larger than Java byte-code.

Note: A 68K JIT is not available at this time. If you are a 68K user make sure that you choose the MSIE/MW VM or the Apple VM (if installed).
