Mac Os 9 System Folder Download Windows

Note: These Disk Copy 4.2 disk images* are stored inside early Stuffit (.sit) archives, which can be extracted by Stuffit Expander 3.5 (and above) in System 6 (and above). You can download Stuffit Expander at MacFixer. In Mac OS X 10.7 and above, The Unarchiver can extract them for use in Mini vMac or via Floppy Emu. If you are using Disk Copy to make floppy disks, don't expand the archives until they reach the machine you will use to make the disks. Avoid handling them on Windows, as it will strip the resource fork from the archive.

System 1.1 Finder 1.1g, released May 1984

Minimum recommended OS for the Macintosh 128K and 512K.

• System Disk [400K] [disk image]
• MacWrite (MacWrite 2.2) [400K] [disk image] (August 1984)
• MacPaint (MacPaint 1.4) [400K] [disk image] (August 1984)
• Backup Disk [400K] [disk image] (August 1984)

Download macOS Big Sur. If you're using macOS Mojave or later, get macOS Big Sur via Software Update: Choose Apple menu System Preferences, then click Software Update. Or use this link to open the macOS Big Sur page on the App Store: Get macOS Big Sur. Then click the Get button or iCloud download icon. This download contains a complete System Folder for Mac OS 9.2.2. The download is called NetBoot9.dmg. Ideally, you should download it to the Mac that will use the 9.2.2 System Folder, but you can use another Mac that runs Mac OS X (to extract the System Folder) and transfer it to the Mac that will use it. I suggest that you grab the first download 'Generic Classic Environment for Mac OS X 10.4 Tiger' because it fits most needs, but feel free to try another Mac OS 9 System Folder if you want. Download it on your Mac OS X 10.4 computer and expand the.sit archive. Then drag the resulting System Folder to the Mac's hard drive. The MacOS9 application contains a standard US-English Mac OS 9 installation, without features that can't be used in this system, such as file-sharing. It also includes a large number of standard Mac OS applications, plus some Control Panels, Extensions, Scripting Additions, and a gray desktop image that you can easily change if you prefer.

This is the first solid Mac Software release, three months after the original Macintosh shipped with what was essentially a public beta release. See Andy Hertzfeld's Real Artists Ship.

System 2.0 Finder 4.1, released April 1985

Recommended OS for the Macintosh 128K.

• System Update [400K] [disk image]

Mac Os Folder Structure

The System Update disk was sent to dealers, for distribution to Macintosh owners. MacWrite 4.5 and MacPaint 1.5 were the current versions for more than two years.

System 3.2 Finder 5.3, released June 1986

Recommended OS for the Macintosh 512K. Maximum OS for the 128K.

• Macintosh Plus System Tools (v1.1) [800K] [disk image]
• Macintosh 512Ke System Tools (v1.0) [800K] [disk image]
• HD 20 Startup [400K] [disk image]
• System Installation (v1.0) [400K] [disk image]
• Printer Installation (v1.1) [400K] [disk image] This is not a direct image of the original disk created on 'Wed, Jun 4, 1986, 3:32 PM.' This is a copy of its contents, complete and unaltered.

System 4.1 Finder 5.5, released April 1987

Recommended OS for the Macintosh 512Ke. Maximum OS for the 512K.

• Macintosh System Tools (v2.0.1) [800K] [disk image] (June 1987)
• Macintosh Utilities 1 (v2.1) [800K] [disk image] (August 1987)
• Macintosh Utilities 2 (v2.1) [800K] [disk image] (August 1987)

Troubleshooting:

On a Macintosh 512K with an external 800K floppy drive:

1. Use the HD 20 Startup disk to boot the machine.
2. Insert the System Tools disk into the external 800K floppy drive.
3. Start an application from the System Tools disk. TeachText, for example.
4. The System Tools disk is now the startup disk. You can remove the HD 20 Startup disk.

On a Macintosh 512K with a Hard Disk 20 hard drive:

• The System and Finder on the HD 20 Startup disk must be the same as the System and Finder on the Hard Disk 20, i.e., System 4.1 Finder 5.5. [This is only an issue with System 4.1 Finder 5.5. System 4.0 Finder 5.4 and below will start with any HD 20 Startup disk.]
• An external 800K floppy drive (attached to the Hard Disk 20) is required for installation, unless you have some other way of moving files from 800K disks to 400K disks.
• The minimum requirement for the HD 20 Startup disk is a System Folder with System 4.1, Finder 5.5, and Hard Disk 20 1.1 in it. See below for information about using Font/DA Mover (you can use the version on the HD 20 Startup disk) to reduce the size of the System file if need be.
• Use the 'Mac Plus, 512Ke, 512K ...' Installer Script in the Utilities Folder on the System Tools disk to update an existing System Folder on the Hard Disk 20.

System 6 disk images from Apple

For information about Macintosh hardware compatibility with System 6.0.x, see Apple Knowledge Base article TA33972: System Software: Version Matrix, System 6.0.x to 7.0.1. While it is possible to run up to System 6.0.8 on a Macintosh 512Ke, some applications may not function on a machine with only 512K of memory, or even 1 Mb.

There are three System 6 releases available for download on the old Apple Support Area server. As of May 2018, the index is not accessible, but the files are still there, just click on the direct links below. Another source for these same files is MacFixer.

• Macintosh System Software 6.0.3, released December 1988 [Read Me] [Disk 1 of 4] [Disk 2 of 4] [Disk 3 of 4] [Disk 4 of 4]
• The System Tools disk contains a complete System Folder.
• The size of the System file with the minimum system font set (see below) and Control Panel installed is 232K.
• Recommended for machines with 1 Mb or less of memory, with a single floppy drive and no hard drive.
• Macintosh System Software 6.0.5, released March 1990 [Read Me] [Disk 1 of 4] [Disk 2 of 4] [Disk 3 of 4] [Disk 4 of 4]
• The System Tools disk contains a bare-bones System Folder. Use the Installer to create a complete System Folder. To install on a Macintosh 512Ke, do a custom installation of 'System software for Macintosh Plus' or 'Minimal software for Macintosh Plus.'
• The size of the System file with the minimum system font set (see below) and Control Panel installed is 281K.
• Recommended for machines 1 Mb or more of memory, with two floppy drives, or a hard drive.
• Macintosh System Software 6.0.8, released April 1991 [Read Me] [Disk 1 of 4] [Disk 2 of 4] [Disk 3 of 4] [Disk 4 of 4]
• The System Tools disk contains a bare-bones System Folder. Use the Installer to create a complete System Folder. To install on a Macintosh 512Ke, do a custom installation of 'System software for Macintosh Plus' or 'Minimal software for Macintosh Plus.'
• The size of the System file with the minimum system font set (see below) and Control Panel installed is 372K.

Troubleshooting:

You can use Font/DA Mover (on the Utilities 2 disk) to reduce the size of the System file and free up space on a floppy disk:

• Desk Accessories: There must be at least one DA installed. Control Panel is a good choice. Include Chooser if your printer or modem ports are in use.
• Fonts: The minimum system font set is Monaco 9, Chicago 12, Geneva 9, Geneva 12. Note that all System 6 releases come with the same Fonts suitcase (on the Utilities 2 disk).

You can also reduce the size of the System Folder. The System Folder on the System 6.0.3 System Tools disk is shown here:

• System documents: The minimum set is System and Finder. It's also a good idea to include Clipboard File.
• MultiFinder, DA Handler, Backgrounder, and PrintMonitor (on the Printing Tools disk) work together. Not recommended for the 512Ke.
• Easy Access is small. Includes Mouse Keys (requires numeric keypad) and Sticky Keys.
• Remove Scrapbook File only if you remove the Scrapbook DA.
• Remove Key Layout only if you remove the Key Caps DA.
• Control Panel documents: These store changes to the default settings. You don't need them if you don't want to make changes. But it's a good idea to include the basics: General, Keyboard, Mouse, and Sound.
• Color, Monitors, and Startup Device are for Macintosh SE and II machines.

Working with older disk images

You can format 800K (2DD: double-sided, double-density) disks as 400K (1DD: single-sided, double-density) disks with no problems. Note that you should use Double Density (DD) media. One reliable source for new disks is OldSoftware.com. You should not use High Density (HD) media. HD disks are not entirely stable when formatted as DD. If you must use HD media, then it should be a disk that has never been formatted. See here (p. 14) for details.

For System 6, you should use Disk Copy 4.2 [Read Me] [Download from Apple] to work with 400K/800K disks and images. This is ideal, since System 6 can read/write 400K disks, which normally use the Macintosh File System (MFS) format. 800K disks use a different format: the Hierarchical File System (HFS). System 6 is fluent in both formats. [It is possible to format 400K disks using HFS, but they can't be used as startup disks. See here.]

System 7 is not ideal, since it does not handle the MFS format properly. This is discussed in Apple Knowledge Base article TA47951: System 7.x: Limitations on Use of 400k Disks. Nevertheless, you can use Disk Copy 4.2 to work with 400K/800K disks and images with no problems. Disk Copy 6.3.3 [Download from Apple] works perfectly with 800K disks and images. It allows you to make compressed images and mount images on the Desktop.

With Mac OS 7.6, Apple dropped support for writing to the MFS format. Mac OS 8 dropped MFS support altogether. However, any Macintosh with a built-in floppy drive can use Disk Copy 4.2 to make 400K/800K disks from images and Disk Copy 6.3.3 to make 800K disks from images, even in Mac OS 9. For more on this, see Sonic Purity.
