    This article describes PACE copy protection, and its interaction with Mac OS 8 and Mac OS 9.

DISCUSSION

    There are some applications (primarily high-end digital audio and MIDI applications) which rely on a Key Disk authorization scheme known as PACE. Essentially, PACE writes a code number to the hard drive which is then verified each time the application is launched.

    Newer PACE-protected applications use the current PACE protocol referred to as "interlok" which installs flawlessly with Apple's Mac OS 8 release. Some applications (Steinberg's Cubase VST 3.5 and earlier, other older Steinberg PACE protected applications and Digidesign's SoundDesigner 2.82 and earlier) use the older, pre-interlok PACE authorization protocol called PACE III. During the install of one of these specific applications, pre-interlok PACE III will perform an expansion of the application. This expansion conflicts with Mac OS 8, preventing the proper installation of pre-interlok PACE III applications over Mac OS 8.

    The good news is that it's an expansion issue, not an authorize/de-authorize problem. If the user does a dirty install of Mac OS 8 where the PACE III protected application has already been installed, the upgrade will work fine and the user will gain all the benefits of Mac OS 8. A user could even de-authorize the PACE protected application, do a clean install of Mac OS 8 and then re-authorize the application and all would still be fine (assuming all appropriate extensions are manually moved from the previous system to the new Mac OS 8 system).

    Simply put, everything should work fine as long as the PACE III protected application is installed (expanded from its tome) before the Mac OS 8 install. Most applications that use the PACE key disk authorization protocol have upgraded to the new "interlok" version which works with fresh installs over Mac OS 8. We encourage you to contact the developer of your software to confirm that you have latest version. They will be able steer you through any small issues you might stumble across.
