Apple 12/600PS manual System requirements, Installing the printer software

System requirements

To use the printer software, you need a Macintosh with a 68020 or higher central processing unit (any Macintosh except a Macintosh Plus, SE, Classic, Portable, or PowerBook 100). Your Macintosh must have system software version 7.1 or later and at least 4 megabytes (MB) of memory. If your system software is an earlier version, you need to obtain a system software upgrade from your computer or software dealer.

Installing all the printer software and fonts for the Macintosh requires approximately 7.5 MB of free space on your hard disk.

Installing the printer software

To install the printer software on a Macintosh computer, follow these steps:

IMPORTANT Do not “drag install” the printer software. If you do, the files won’t be properly decompressed and won’t work.

1Turn off any automatic virus-detection programs you have on your Macintosh computer.

If you don’t, problems may occur during the installation. After installation is complete, you can turn the virus-detection programs back on. (For instructions on turning off each virus-detection program, see the manual that came with the program, or telephone the manufacturer of the program.)

2Press and hold down the Shift key, then choose Restart from the Special menu.

When a message on the screen tells you that the extensions are off, you can release the Shift key. Your extensions have been turned off. When you restart the Macintosh after a successful installation, the extensions will turn on again.

3Make sure the printer software disks are locked.

4Insert Printer Disk 1 for Macintosh into a disk drive.

If necessary, open the disk icon.
