System 7. Compatibility With Macintosh Computers.

No system enabler needed with System 7. If so, you may have to boot from a special startup floppy with an appropriate CD-ROM extension instead.

For example, a modified Network Access Disk 7. Oct 6, 2: If necessary, a Network Access floppy can be used as a plain boot disk without the need for a system enabler. That way, you would be able to connect to a file server on a second Mac, thus allowing file transfers to the hard disk in a machine like your Color Classic. This would create a startup floppy for special purposes such as for accessing an external CD-ROM drive. Alternatively, a modified Network Access floppy with free space can be used as a mere carrier for a transfer of a small file one example would be a system enabler, placed outside the system folder on the floppy in this very context.

Use Disk Copy 4. Oct 16, 6: Try to install 7. As it seems that for any reason you cannot boot from CD this can solve the problem. Put the first install disk with Mac turned off and then turn it on to start the installation. More Less. Communities Contact Support. Sign in. Browse Search. Ask a question.

System 7 was developed for Macs that used the Motorola x0 line of processors, but was ported to the PowerPC after Apple adopted the new processor in with the introduction of the Power Macintosh.

The development of the Macintosh system software up to System 6 followed a fairly smooth progression with the addition of new features and relatively small changes and upgrades over time. Major additions were fairly limited, notably adding Color QuickDraw in System 6. Some perspective on the scope of the changes can be seen by examining the official system documentation, Inside Macintosh. This initially shipped in three volumes, adding another to describe the changes introduced with the Mac Plus , [2] and another for the Mac II and Mac SE.

These limited changes meant that the original Macintosh system remained largely as it was when initially introduced. That is, the machine was geared towards a single user and task running on a floppy disk based machine of extremely limited RAM. However, many of the assumptions of this model were no longer appropriate. Most notable among these was the single-tasking model, the replacement of which had first been examined in 's "Switcher" and then replaced outright with MultiFinder in System 5.

Running MultiFinder normally required a larger amount of RAM and a hard drive , but these became more common by the late s. While additions had been relatively limited, so had fixes to some of the underlying oddities of the system architecture. For instance, to support a limited form of multitasking, the original Mac OS supported small co-resident programs known as desk accessories which had to be installed into the system using special tools.

If the system were able to support multiple tasks, this one-off solution would no longer be needed — desk accessories could simply be small programs, placed anywhere. Yet, as MultiFinder was still optional, such a step had not been taken. Numerous examples of this sort of problem could be found throughout the system. Finally, the widespread adoption of hard drives and local area networks led to any number of new features being requested from users and developers. By the late s, the list of new upgrades and suggested changes to the existing model was considerable.

In March , [N 1] shortly before the release of System 6, technical middle managers at Apple held an offsite meeting to plan the future course of Mac OS development. As Blue was aimed at relatively "simple" upgrades, the feature list reads to some degree as a sort of "System 6, corrected". In the underlying OS, a number of formerly optional components were made mandatory:. Furthermore, a number of oddities in the original System, typically included due to limited resources, were finally changed to use basic underlying OS features:. System 7 was the first Apple operating system to be available on compact disc , although it shipped on a set of 15 floppy disks initially.

Unlike earlier systems, System 7 did not come bundled with major software packages. Since System 7 was introduced before the Internet came to popular attention, software such as MacTCP , FreePPP and Netscape were not included at first, but was later available on disk from Internet service providers and bundled with books such as Adam C.

Engst 's Internet Starter Kit for Macintosh. Power Macintosh machines also included NuCalc , a graphing calculator. System 7 also includes AppleTalk networking and file sharing software in the form of system extensions and control panels. The basic utilities installed by default with System 7 include TeachText which was replaced by SimpleText in later versions for basic text editing tasks and reading readme documents. Later versions of System 7, specifically System 7. More optional extras and utilities could be manually installed from the System CD. System 7. Fat binaries , which contained the code necessary to run natively on both PowerPC and 68k systems, became common during this time.

This process was similar to the distribution of universal binaries during Apple's transition to Intel processors in System 7 Pro, System 7. The PC could run simultaneously with the Mac, and the user could switch between the two in a fashion similar to a KVM switch. The earliest of these systems were x0 based systems running System 7.

System 7 provided the support for accessing the PC volume from the Mac through its own PC Exchange software, and actual control of the PC hardware was accomplished by way of control panels. At the time of its release, many users noticed that performance suffered as a result of upgrading from System 6 to System 7, [ citation needed ] though newer hardware soon made up for the speed difference.

Another problem was System 7's large "memory footprint": System 6 could boot the system from a single k floppy disk and took up about KB of RAM , whereas System 7 used well over a megabyte. It was some time before the average Mac shipped with enough RAM built in for System 7 to be truly comfortable. System 7 was the first system release that could no longer be usefully run on floppy-only systems. Although most Macintosh models sold at the time included a hard disk as standard equipment, owners of older models were required to upgrade by buying either a new Mac or external SCSI hard disk drive if they wished to run System 7.

In order to take advantage of System 7's virtual memory feature, a Macintosh equipped with a paged memory management unit PMMU is required. The other Macintosh model using an , the Macintosh LC , cannot use virtual memory. Despite the newer processor, the LCII retained the earlier model's bit bus and did not perform any faster than the LC it replaced. Despite these setbacks, System 7. The engineering group within Apple responsible for System 7 came to be known as the " Blue Meanies ", named after the blue index cards on which were written the features that could be implemented in a relatively short time as part of Apple's operating system strategy.

In comparison, the pink index card features were handled by the Pink group, later becoming the ill-fated Taligent project.

Although System 7 could be purchased from Apple, the cost was nominal and considered to only cover duplication and media. It was common for Macintosh dealers to allow customers to use the store's demo machines to copy System 7 install disks for the cost of a box of floppies. Apple continued charging for major operating system upgrades until the release of OS X Mavericks in Soon after the initial release of System 7, the 7.

A patch called "System 7 Tune-Up" also followed, which fixed the "disappearing files" bug in which the system would lose files [11] and added "minimum" and "preferred" memory allotments to an application's Get Info box.
