System 6#Reception

The MacroMaker utility was introduced in System 6.{{Cite magazine |last=Forbes |first=Jim |date=April 12, 1988 |title=Apple to enhance system software, desktop database. |magazine=PC Week |pages=11}} It records mouse and keyboard input as macros, and has a unique user interface intended to look and act like a tape recorder.{{Cite magazine |last=Beaver |first=David |date=July 19, 1988 |title=Some simpler solutions to making macros (MacroMaker and AutoMac III macro recorders for the Macintosh) |magazine=MacWEEK |pages=44}} MacroMaker was criticized for its lack of features when compared to Microsoft's AutoMac III, which was already available commercially. As MacroMaker records only the locations of mouse-clicks inside windows and not what is being clicked on or exactly when, it can not be used to automate actions in more sophisticated programs. The pre-recorded clicks miss buttons if the buttons had moved since the recording, or if they failed to appear upon playback. It records the start and end locations of mouse movements, but does not track the precise path of a movement or support pauses.{{Cite book |last=Heid |first=Jim |url=https://archive.org/details/mac_Inside_the_Apple_Macintosh_-_Held_Norton_1989 |title=Inside the Apple Macintosh |last2=Norton |first2=Peter |publisher=Simon & Schuster, Inc. |year=1989 |isbn=0-13-467622-X |series=The Peter Norton Foundation series |pages=[https://archive.org/details/mac_Inside_the_Apple_Macintosh_-_Held_Norton_1989/page/n340 333]–334 |author-link2=Peter Norton}} MacroMaker is not compatible with System 7, in which it is succeeded by AppleScript.{{Citation needed|date=March 2022}}

Macintosh gained cooperative multitasking in March 1985 with Andy Hertzfeld's Switcher, which can switch between multiple full-screen applications.{{Cite book |last=Hertzfeld |first=Andy |title=Revolution in the Valley |publisher=O'Reilly |year=2005 |isbn=0-596-00719-1 |pages=243–251}} It was not integrated, and was only sold separately by Apple. Not many programs and features function correctly with Switcher, and it does not share the screen between applications simultaneously. Systems 5 and 6 have MultiFinder instead,{{Cite magazine |last=Wiggins |first=Robert R. |date=March 1988 |title=All systems go (System Tools 5.0 with MultiFinder) |magazine=MacUser |pages=126}} which is much more mature and widely used in System 6. With MultiFinder, the Finder does not quit to free resources, and the system behaves as in the still-familiar multitasking fashion, with the desktop and other applications' windows in the background.{{Cite web |date=September 1, 1987 |title=Apple Talks About Multifinder |url=https://www.savetz.com/ku/ku/applelink_apple_talks_about_multifinder_september_1987.html |access-date=December 2, 2024 |website=Known Users}}

System 6 includes support for the Apple ImageWriter LQ and PostScript laser printers. New software drivers allow the ImageWriter LQ to be used on AppleTalk local area networks and supports the use of tabloid or B-size paper ({{convert|11|x|17|in|mm|abbr=on|disp=or}}). System 6 includes QuickerGraf (originally QuickerDraw), system software used to accelerate the drawing of color images on the Macintosh II. It was licensed to Apple and Radius Inc. by its programmer, Andy Hertzfeld.

In comparison to the NeXTSTEP operating system of the time, System 6 does not make much use of sound, and its user interface is limited in file management and window displays. System 6's Apple menu cannot be used to launch applications. The icon in the upper right-hand corner of the menu bar simply shows the open application and is not a menu.{{Cite magazine |last=LeVitus |first=Bob |date=July 1991 |title=System 7.0: 10 reasons why you'll love it |magazine=Computer Shopper |pages=202}} System 6 supports 24 bits of addressable RAM (random-access memory), which allows for a maximum of 8 megabytes of RAM, with no provision for virtual memory.{{Cite magazine |date=August 1991 |title=Settling down with System 7 (Apple Macintosh operating system's compatibility with network operating systems and upgrading benefits) |magazine=The Local Area Network Magazine |pages=18}} These limitations were removed in System 7. System 6's version of the HFS file system also has a volume size limit; it supports up to 2 gigabytes (GB) and 65,536 files on any one volume. System 7.5 increased this limit to 4 GB, and 7.5.2 increased it further to 2 TB on certain machines, specifically PCI-based Macintosh models.{{Cite web |date=January 17, 2007 |title=Macintosh: File System Specifications and Terms |url=http://docs.info.apple.com/article.html?artnum=8647 |archive-url=https://web.archive.org/web/20080508023713/http://docs.info.apple.com/article.html?artnum=8647 |archive-date=May 8, 2008 |access-date=March 9, 2019 |publisher=Apple Inc}}

The Trash (known as the "Wastebasket" in the British-English version) empties when the Finder terminates.{{cite web |last=Panic |first=Major General |date=August 1, 2006 |title=trash can |url=https://everything2.com/title/trash+can |access-date=December 2, 2024 |website=Everything2.com}} Icons on the Desktop in System 6 are not organized into a single folder, as in later operating systems. Instead, the system records if a file is on the Desktop.{{Cite magazine |last=LeVitus |first=Bob |date=March 1992 |title=Top ten secrets of System 7 (Beating the System) |magazine=MacUser |pages=213}} This is inefficient and confusing, as the user cannot browse to the Desktop in applications besides the Finder, even within the standard Open and Save As dialog boxes. Furthermore, these dialogs are primitive, and were mostly unchanged since 1984. The lack of aliases, shortcuts to files, is another limitation of file management on System 6,{{Cite magazine |last=Michel |first=Steve |date=May 14, 1991 |title=Aliasing: a file by any other name. (making duplicate files with minimal disk space) (System 7.0 Survival Guide) |magazine=MacWEEK |pages=S13}} and custom file and folder icons are not supported. These issues were all remedied in System 7.{{Cite web |last=Knight |first=Daniel |date=February 19, 2001 |title=Not the End of the Mac as We Know It |url=https://lowendmac.com/musings/end.html |access-date=December 2, 2024 |website=Low End Mac}}

A maximum of 15 desk accessories may be installed at one time, including the Chooser, Scrapbook, and Control Panel.{{Cite magazine |date=March 1, 1988 |title=Font/DA Juggler Plus |magazine=MacUser |pages=27 |quote=Now you can break the Macintosh barrier of 15 DAs, 200 fonts, and 8 FKeys.}}{{Cite magazine |last=Aker |first=Sharon Zardetto |date=May 1, 1988 |title=DAs of Our Lives |pages=203 |magazine=MacUser |quote=Then came hard disks and megaRAMs, and a System update that included scrolling menus. That basically solved the font problem, but there was still a System limitation of 15 "slots" in the Apple menu for accessories.}} System 6 uses the Control Panel desk accessory to access all the installed control panels, which imposes severe user-interface limitations. In System 7, Control Panels are contained in separately openable panels, and are held in a central folder for better organization.{{Cite book |last=Everson |first=Sharon |url=https://archive.org/details/insidemacintoshm00appl/ |title=Inside Macintosh: More Macintosh Toolbox (Apple Technical Library) |date=October 1992 |publisher=Addison-Wesley |isbn=0-201-63243-8 |pages=7-41 |format=PDF |url-access=registration}} Desk Accessories cannot be installed or removed within the Finder; this requires the Font/DA Mover utility. System 7 also fixed this.{{Cite book |last=Everson |first=Sharon |url=https://archive.org/details/insidemacintoshm00appl/ |title=Inside Macintosh: More Macintosh Toolbox (Apple Technical Library) |date=October 1992 |publisher=Addison-Wesley |isbn=0-201-63243-8 |pages=7-37 |format=PDF |url-access=registration}}

The interface is not very customizable. The Finder allows each icon to be assigned a color, but the desktop background is limited to an 8x8-pixel color tiled pattern (color patterns were introduced in System 5),{{Cite magazine |last=Wiggins |first=Robert R. |date=March 1, 1988 |title=All systems go. (Software Review) (System Tools 5.0 with MultiFinder.) |magazine=MacUser |quote=Many of the cdev modules that come with System Tools 5.0 are for the Macintosh II, including a new one called "Color" that allows you to change the highlight color, the color used as a background when text or an icon is selected. The General cdev also adds the ability to set the desktop pattern color on a Macintosh II.}} and standard window frames are black-and-white. However, many "INIT" extension files exist to add color and customization.{{Cite magazine |date=March 1990 |title=Color Icons |url=https://www.wap.org/journal/showcase/washingtonapplepijournal1990v12no3mar90.pdf |url-status=live |magazine=Washington Apple Pi |volume=12 |issue=3 |page=86 |archive-url=https://web.archive.org/web/20210919083909/https://wap.org/journal/showcase/washingtonapplepijournal1990v12no3mar90.pdf |archive-date=2021-09-19 |access-date=2022-05-13}} System 7 allows the user to change the color of window frames and various other aspects of the user interface.{{Cite magazine |last=Crabb |first=Don |date=June 1989 |title=The Mac Interface: Showing Its Age |magazine=Byte |pages=235–237}} By 1989, the System 6 user interface was in need of a change.

Initial releases of System 6 are unstable; Don Crabb of BYTE described 6.0 as "buggy and unreliable".{{Cite magazine |last=Crabb |first=Don |date=February 1989 |title=Hey Apple, I Need a Laptop |url=https://archive.org/details/eu_BYTE-1989-02_OCR/page/n205/mode/2up?view=theater |access-date=2024-10-08 |magazine=BYTE |pages=151-154}} Many third-party developers did not receive advance copies, resulting in widespread compatibility issues. The contemporary versions of many common programs such as Microsoft Excel, Microsoft Works and 4th Dimension were not fully compatible with System 6. There were also software bugs in the Color Manager, Script Manager, and Sound Manager extension files. Apple announced that 66 bugs were fixed with version 6.0.1 update, in September 1988.{{Cite magazine |date=September 13, 1988 |title=System 6.0.1 set for distribution |magazine=MacWEEK}}{{Cite magazine |last=Perrow |first=Jonathan |date=September 20, 1988 |title=System 6.0 saga not over yet |magazine=MacWEEK |pages=2}} However, a major bug involving the text-spacing of screen fonts was found, and was fixed in version 6.0.2, which Crabb described as "a huge improvement" over 6.0.{{r|crabb198902}} Some customers waited longer until moving to System 6 because of its poor reputation.{{Cite magazine |date=October 25, 1988 |title=Managers go slow with System 6.0.2 |magazine=MacWEEK |pages=2}}

System 6 was officially supported by Apple for many different machines, some of which shipped with it. Some unsupported Macintosh computers can run it with limitations.{{Cite web |date=November 30, 1994 |title=PowerBook & Macintosh Classic II: No Support for System 6 |url=http://docs.info.apple.com/article.html?artnum=9140 |url-status=dead |archive-url=https://web.archive.org/web/20120426172351/http://docs.info.apple.com/article.html?artnum=9140 |archive-date=April 26, 2012 |access-date=May 3, 2008 |publisher=Apple Inc}}
