As I mentioned in my Setting up your vintage (classic) 68k Macintosh not every Macintosh System can run every OS, for example System 7.5.5 was the last version to support the original Macintosh Systems with their Motorola 68000 (68k) processors, 7.6 required Systems with a 68030 and 32bit clean ROMs, with support for 68k processors ending with System 8.1. I also include some information about PPC systems, but my main focus for this page is 68k systems.
To help myself in the future I created some Macintosh System Compatibility Tables so I know which systems support which versions (with links to any required the System Enablers for OS 7.x). The tables were created from information found in Apple’s Technical Information Library / Knowledge Base articles:
- System Software Version History (TIL15582 / TA31885),
- System Software: Version Matrix, System 6.0.x to 7.0.1 (TIL18046 / TA33972),
- System 7.1 through Mac OS 7.6: Compatibility With Macintosh Computers (TIL08970 / TA47341)
Note: The Macintosh XL uses a custom OS called MacWorks so is not included in the tables below.
Systems covered by this page
- Releases 1.0, 1.1, 2.0, 2.1, 3.0, 3.1, 3.2, 3.3, 3.4, 4.0, 4.1, 5.0, 5.1
- Releases 6.0, 6.0.1, 6.0.2, 6.0.3, 6.0.4, 6.0.5, 6.0.6, 6.0.7, 6.0.8, 6.0.8L, 6.0.8P, 7.0, 7.0.1
- Releases 7.1, 7.1.1 (Pro), 7.1.2, 7.1.3, 7.5, 7.5.2, 7.5.3, 7.5.5, for 68k Systems, and PPC Systems
- Releases 7.6, 7.6.1, 8.0, 8.1
! | – Not supported |
OK | – Works with this version of system software |
# | – Works with this version of system software, but requires a Macintosh System Enabler, where ### = the ID code of the enabler (e.g. the enabler for the Color Classic to run 7.1 or 7 Pro is 401, and the last released version is 1.0.5) |
??? | – Works with this version of system software, but requires a Macintosh System Enabler, but I could not find information for which enabler. |
1. System Software Release 1 to 5 Compatibility:
Note, prior to System 6.x the System number/naming for the Macintosh OS was…. different, below I try to provide the set of information that you need to identify each release of new system software.
- 1.0: 1984/01, System 1.0 / Finder 1.0 / System Software 0.97, Introduced with the Macintosh 128k
- 1.1: 1984/05, System 1.1 / Finder 1.1g and 1.1h / System Software
- 2.0: 1985/04, System 2.0 / Finder 1.1g / System Software 0.1
- 2.1: 1985/04, System 2.0 / Finder 4.1 / System Software 0.3
- 2.1 HD20: 1986/01, System 2.0 / Finder 5.0, introduced support for the Hierarchical File System (HFS) for use the Macintosh Hard Disk 20 (emulated by the FloppyEMU) that was specifically released for the Macintosh 512.
- 3.0: 1986/01, System 3.0 / Finder 5.1 System Software 0.7, introduced support 800k floppy disks (Double Sided), and for SCSI, with a maximum partition size of 32MB. SCSI would become a standard feature starting with the Macintosh Plus.
- For the Macintosh 128: the driver was loaded from RAM when booting from a floppy drive, and took too much RAM to be used with the Macintosh 128k.
- For the Macintosh 512: required a special boot diskette that begins the boot up process, and on detecting the Macintosh Hard Disk 20, ejects the disk and then continues loading from the Hard Disk.
- For the Macintosh 512Ke: native support for HFS was added to the ROM allowing for this system (and the Plus) to boot directly form the Macintosh Hard Disk 20 without using a floppy disk.
- HFS has a limit of 65,535 files per logical disk (e.g. partition/volume).
- A way around the file limit is to use a tool like ShrinkWrap to create mountable disk images.
- 3.1: 1986/02, System 3.1 / Finder 5.2 (buggy, do not use) / System Software 1.0
- 3.1.1: 1986/02, System 3.1.1 / Finder 5.4
- 3.2: 1986/06, System 3.2 / Finder 5.3 / System Software 1.1
- 3.3: 1987/01, System 3.3 / Finder 5.4 / System Software 2.0
- 4.0: 1987/03, System 4.0 / System Software 2.0.1 *
- 4.1: 1987/04, System 4.1 / Finder 5.5 / System Software 2.0.1 *, Introduced support for 2GB partitions (See Apple TIL/KB Article 8647)
- 5.0: System 4.2 / Finder 6.0 / System Software 5.0: disk contents: TIL13431 / TA30217)
- 5.1: System 4.3 / Finder 6.0 / System Software 5.1: disk contents: TIL13432 / TA30218), last supported system for unmodified the 128K, 512K, and 512Ke systems.
* Note: I’ve found that the information provided in the System Software Version History (TIL15582/TA31885) does not match up with the information found in some of the knowledge base articles, TIL133447 / TA30234 states that the System Software 2.0 disks have System 4.1, Finder 5.5 and LaserWriter 4.0, with TIL13430 / TA30216 states that System 2.0.1 disks have System 4.1, Finder 5.5 and Laser writer 4.0.

3. System Software Release 7.1 to 7.5.5 Compatibility (introduced System Enablers)
These tables are based on the the tables from Apple knowledge base (TA47341), I created these with the assumption that the source article may be removed in the future (like many other articles that dealt with the vintage systems). I’ve also included links to any System Enablers needed for an OS to work properly on a system. Because Apple has removed these files from their site I’m linking to the cached copies on the Internet Archive. I’m also hosting these files on my site and will link to my copy if they ever disappear off the Internet Archive. For anyone that wants to have a copy of all the System Enablers they can also be found on the Macintosh Garden.
3.1. About System Enablers:
In the past when Apple released new computers the system software was revised. To get around this problem system enablers were written which contained information necessary for newer computers to start up. All Apple computers released since system software 7.1 (September 1992) require a system enabler to start up. For more information see my post on Current Version and Change History for these enablers.
System 7.5 contains a universal enabler that supports all computers released before System 7.5.
3.2. 68k Systems:
- Before installing System 7 confirm that you have at least 2 Megabytes of RAM, preferably at least 4.
- The Macintosh Plus, SE, SE/30, Classic, Classic II, LC, LC II, LC 580, Mac II, IIx, IIcx, IIsi, IIci, IIfx, Portable, PowerBook 100, 140, 145, 145B, 170, Quadra 700, 900, and 950, and Performa 200, 400, 405, 410, 430, 580, 640 and 6110-series all do NOT need a System Enabler. System 7 and System 7.1: System Requirements, System 7: INITs or System Extensions in System 7
- System 7.0, 7.0.1, 7.0.1P, 7.1, 7.1P, 7.1P1, 7.1P2, 7.1P3, 7.1P5, 7.1P6, and System 7.5 comparison
- System 7.1: 1.4MB disk contents, 800k disk contents, installing from 800k disks
- System 7.1.1 = System 7 Pro readme, installation, disk contents
- System 7.1.2P = System 7 release that introduced support for Power Macintosh
- System 7.1.3 = System 7.1, 7.1.1 or 7.1.2 with System Update 3.0 revision 2
- System 7.5 introduced support for 4GB partitions, but kept the HFS limit of 65,535 files per logical disk (e.g. partition) (See Apple KBase Article 8647), upgrade kit contents, color picker issue, new features
- System 7.5.2 introduced support for 2TB partitions on some systems. (Systems released with 7.5.2 installed and systems that support PCI, from what I can see no 68k system meets those requirements, see Apple KBase Article 8647)
- System 7.5.5 was the last to support 68k macs with less than a 68030 CPU
- System 7.6 only supports 68k macs with a 68030 CPU or better, and Macs with 32-bit-clean ROMS (the Mac II, Mac IIx, Mac IIcx, and Mac SE/30 do NOT have 32 bit clean ROMS)
- (1) The system was initially released with only 1 Megabyte of RAM but can be expanded to 4 or more Megabytes. (minimum for OS 7.1.x is 2 Megabytes of RAM)
- (2) The system was initially released with only 2 Megabytes of RAM but can be expanded to 4 or more Megabytes. (minimum for OS 7.5.x is 4 Megabytes of RAM)
- (#) The Apple Workgroup Server 95 uses the A/UX operating system.
- + Also requires: System 7.5.5 SCSI Server Update, and PPC Interrupt Extension.
- (A) System Enabler 131 replaces System Enabler 111 and System Enabler 121
- (B) Express Modem users should also install the Duo Battery Patch extension)
- (D) These computers shipped with 7.5.5 and require the enabler that shipped with it. These computers do not support Mac OS 7.6 but support Mac OS 7.6.1.

4. System Software Release 7.6 to 8.1 Compatibility
With the release of System 7.6 apple ended support for the majority of it’s earlier systems. System 7.6 requires a 68030 CPU, 8MB of RAM and a 32-bit clean ROM (all computers with 68030 microprocessors are 32-bit clean except the Macintosh SE/30, Macintosh IIx, and the Macintosh IIcx). There are also a small number of PPC systems that are NOT supported: PowerMacs 7300, 8600, 9600.
With System 8.0 the requirement increased to 68040 and 12MB of RAM (20MB recommended), but there is a hack that will let you run System 8.0 and 8.1 on systems with 68030 CPUs.
- System 7.6: system requirements, clean install, base vs. all, no GeoPort software, blinking question mark after install
- System 7.6.1: CD-ROM driver issue, Hacking Mac OS 7.6.1 to Work with Many OS 8 Apps
- Mac OS 8.0: what’s new, installation, boot from CD issue, proDOS partitions will not mount, no GeoPort software, Backporting HFS+ to Mac OS 8.0 and earlier
- Mac OS 8.1: what’s new, hfs+ startup disk, hfs+, how to install, pc setup sound issue, using non-apple CD-ROM drives
Hi!
I have a Powerbook 170 from 1991.
I need floppy discs to reeboot the system.
Can I use any floppy disc inkl. system 7.0.1 to 7.6.1
Even if it belongs to a plus or SE or other Mac from that erea
Thanx
Since the PowerBook 170 requires no enablers, you can use any of the installers that are compatible. At this time in Macintosh history you could drop in an installer disk and select if you’d like to have the custom Mac OS for your specific model or a system folder with software compatible with EVERY Mac.
