Internet Explorer for Mac (also referred to as Internet Explorer for Macintosh, Internet Explorer Macintosh Edition, Internet Explorer:mac or IE:mac) was a proprietary web browser developed by Microsoft for the Macintosh platform to browse web pages. Initial versions were developed from the same code base as Internet Explorer for Windows. Later versions diverged, particularly with the release of version 5, which included the cutting-edge, fault-tolerant and highly standards-compliant Tasman layout engine.
As a result of the five-year agreement between Apple and Microsoft in 1997, it was the default browser on the classic Mac OS and Mac OS X from 1998 until it was superseded by Apple's own Safari web browser in 2003 with the release of Mac OS X 10.3 "Panther".
On June 13, 2003, Microsoft announced that it was ceasing further development of Internet Explorer for Mac and the final update was released on July 11, 2003. The browser was not included in the default installation of Mac OS X 10.4 "Tiger" which was released on April 29, 2005. Microsoft stopped releases for the product on December 31, 2005, and they removed the application from their Macintosh downloads site on January 31, 2006. Microsoft recommended "that users migrate to more recent web browsing technologies such as Apple's Safari." An archived version of the download is available on Softonic.com, but only works on Mac OS X 10.6 and earlier versions, because of the discontinuation of Rosetta. A Microsoft browser would not return to the macOS platform until Microsoft Edge in 2019.
Versions of Internet Explorer for Macintosh were released starting with version 2 in 1996, to version 5 which received its last patch in 2003. IE versions for Mac typically lagged several months to a year behind Windows versions, but included some unique developments, including its own layout engine, called Tasman.
Internet Explorer 2.0 for Macintosh
The first version of Internet Explorer for the Macintosh operating system was a beta version of Internet Explorer 2.0 for Macintosh, released on January 23, 1996, as a free download from Microsoft's website. This first version was based on the Spyglass Mosaic web browser licensed from Spyglass. Available for both 68k and PPC based Macs running System 7.0.1 or later, it supported the embedding of a number of multimedia formats into web pages, including AVI and QuickTime formatted video and AIFF and WAV formatted audio. The final version was released three months later on April 23. Version 2.1 released in August of the same year, was mostly aimed at fixed bugs and improving stability, but also added a few features such as support for the NPAPI (the first version of Internet Explorer on any platform to do so) and support for QuickTime VR. AOL 3.0 for Macintosh used the IE 2.1 rendering engine in its built-in web browser.
Internet Explorer 3.0 for Macintosh
Internet Explorer 4.0 for Macintosh
At the 1997 Macworld Expo in Boston, on August 6, Steve Jobs and Bill Gates announced a partnership between Microsoft and Apple. Amongst other things, Apple agreed to make Internet Explorer the default browser instead of Netscape Navigator.
Five months later on January 6, 1998, at the Macworld Expo in San Francisco, Microsoft announced the release of the final version of Internet Explorer version 4.0 for Macintosh. Version 4 included support for offline browsing, Dynamic HTML, a new faster Java virtual machine and Security Zones that allow users or administrators to limit access to certain types of web content depending on which zone (for example Intranet or Internet) the content was coming from. The most publicized feature of Internet Explorer 4.0 was support for Microsoft's Active Channel technology, which was intended to deliver regularly updated content that users could personally tailor to their interests. However Active Channel failed to reach a wide audience.
At the same event, Apple announced the release of Mac OS 8.1. This was the first version of the Macintosh operating system to bundle Internet Explorer as its default browser per the agreement with Microsoft; however, version 4.0 was not ready in time to be included so version 3.01 was bundled on the CDs.
At the following year's San Francisco Macworld Expo on January 9, 1999, Microsoft announced the release of Internet Explorer 4.5 Macintosh Edition. This new version, which dropped 68K processor support, introduced Form AutoFill, Print Preview, the Page Holder pane which let a user hold a page of links on one side of the screen that opened pages in the right hand and support for Mac OS technology like Sherlock.
Internet Explorer 5 Macintosh Edition
Another year later, on January 5, 2000, Microsoft announced a new version of Internet Explorer at the San Francisco Macworld Expo, Internet Explorer 5 Macintosh Edition which was released two months later on March 27, 2000. The Windows version of Internet Explorer 5 had been released a year earlier, but used the Trident layout engine. The Macintosh Edition introduced a new rendering engine called Tasman that was designed to be more compliant with emerging W3C standards such as HTML 4.0, CSS Level 1, DOM Level 1, and ECMAScript. It also introduced a number of features that were later added to other browsers such as complete support for the PNG image standard (which previous versions did not support at all), DOCTYPE switching, Text Zoom and XML source view. It also included an Auction Manager for tracking auctions in sites like eBay and an Internet Scrapbook to allow users to quickly and easily store and organize web content (for example an image or a piece of selected text). Preview releases of the browser included a feature called the MediaBar which integrated MP3 and internet radio playback, but this feature was dropped from the final version. The initial release was just for Mac OS 8 and Mac OS 9, however two months after that release on May 15 a Mac OS X version was released, bundled with the Mac OS X DP4 release handed out to developers at the 2000 Worldwide Developers Conference. The Mac OS X Public Beta included another preview of the Mac OS X version of IE. The release of Mac OS X 10.0 on March 24, 2001, included yet another preview of the Mac OS X version of IE 5. This was updated later, and the release of Mac OS X v10.1 on September 25, 2001, included the final version of Internet Explorer 5.1 for Mac OS X. IE 5.1 for Mac OS 8 and 9 was released on December 18, 2001.
According to Jorg Brown, one of the IE for Mac developers at Microsoft, after version 5 most of the team that produced IE for Mac were moved to another project. IE for Mac was relegated to something they were expected to work on in their "spare time".
On June 17, 2002, Microsoft announced the release of version 5.2 (the first Mac OS X-only release) which included a few performance and security fixes and support for Mac OS X features, like Quartz text smoothing.
In 2002, Microsoft reassigned developers to develop version 6 of Internet Explorer for Mac, intended to be used as the base for a new product. MSN for Mac OS X would be a subscription-only browser that worked with the online MSN service, incorporate features like an address book, junk mail filters and an MSN Messenger client. However, after hearing that Apple had started development of their own browser, they canceled the standalone browser development and concentrated on the MSN browser, which was released on May 15, 2003.
On June 13, 2003, PC Pro reported that Macintosh Business Unit general manager Roz Ho had confirmed that aside from updates to fix security problems, there would be no new versions of Internet Explorer from Microsoft. Three days later on June 16, 2003, Microsoft released the final version for Mac OS X (PPC), version 5.2.3 and a month later on July 11, 2003, they released the final version for Mac OS 8 and 9, version 5.1.7. The last versions of Internet Explorer for Mac OS X (PPC) had a distinguishing blue logo that was the base for the logo used in Internet Explorer 6 for Windows (the Windows one just had a lighter blue, and it was less three-dimensional).
These are features found in Internet Explorer for Mac, which were not found in common contemporary browsers (with the possible exception of Internet Explorer for Windows). Some are still not features in many browsers.
- Support for annotative glosses to Japanese kanji and Chinese characters (see furigana).
- Scrapbook feature lets the user archive any page in its current state.
- Auction Manager feature automatically tracks eBay auctions.
- Although Internet Explorer for Mac did not have any PNG support at all until version 5.0 (a year or two after other major browsers), the PNG support added in that version was unusually robust, including transparency and color correction.
- Support for matching web page colors using ColorSync.
- An option to change the browser color, to match the colors of the iMac G3. The first builds had a choice of 9 colors, but later builds had 15.
- The URL auto-complete window in the pre-Carbon versions was translucent and blurred the content behind to maintain readability of the suggested completions. This is the first time an app had a blurred translucent window and an effect similar to the look of iOS 7 years later. The later Carbon versions just used Mac OS X built-in window translucency without blurring.
- Print Preview functionality allowing for adjustment of the font-size from within the preview pane.
- Page Holder sidebar functionality allowing users to hold a rendered page in the sidebar (a links-only view was available too) and load clicked links in the main browser window. Much of this functionality was replaced with tabbed browsing in later browsers, but not the links-only view.
- As with previous IE Mac versions, and in common with many other Macintosh internet software, the URL from which content was downloaded is added to the Finder's Comment field (visible through Get Info).
- Support for the Internet Config system. Macintosh versions of Internet Explorer were characterized by strong support for Macintosh-only technologies, generally to a greater degree than Netscape Navigator.
These are features found in Internet Explorer for Mac and some other of its contemporaries.
- Auto-complete in the address bar responds to typing partial URLs or page titles, searches favorites and history
- Go menu allows access to the persistent global browser history
- Tasman rendering engine offers superior CSS support compared to Trident in other Internet Explorer 5 versions, and was not affected by the Internet Explorer box model bug (not fixed in Trident until IE 6)
- Text zoom allows the user to resize text on any page, regardless of how text size is specified
