If you do, and you use a MIDI product that uses PACE copy protection, here's the latest information from Apple, Pace, and some of the software houses that use PACE. In essence, you CAN upgrade to MacOS 8 and continue to use CuBase or SoundDesigner, just read below to see what you may need to do to

>PACE Key Disk Copy Protection with OS 8:
>
>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.

Most newer 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 currently 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/deauthorize 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 deauthorize the PACE protected application, do a clean install of Mac OS 8 and then reauthorize 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 it's 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 beautifully 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 stuble accross.
