Hi Daisy, I'm not a tech, but I would offer this. I've tried everything on the Digidesign site (uninstalling, etc.) and, now, I'm at a complete loss. Then, it usually says the code is wrong, twice, but, then, allows me to use the program anyway but telling me I should contact the office. Also, each time I have to re-open the program, it asks me for my code. O.K., I tried the Workspace Browser switch - didn't work - and my drive is greyed out in the Disk Utility.

Tiger made some significant changes in audio processing and disk usage. I waited for Tiger until I saw updates for my Quickbooks Pro, Final Cut Pro, Macjanitor, Audio Hijack Pro, Fetch and others before buying the upgrade. I enjoy watching the early adopters slugging through their compatibility problems. There are many good resources on the web to read before you upgrade.

perhaps you have learned a valuable lesson. And to those who upgraded before checking if PT was compatible. Sorry to those who bought a new Mac without checking to see first if the software they wanted to run was compatible. But for one commercial client, I upgraded their 001 to a 002 and this week upgraded their PT to 6.9.2. I don't have to pay Digi one more red cent. I have a personal 001 system that is still on OS 9.2.2 and it is stable and does all I need for playing around. I am not aware, for instance, on any Mac OS update that made Pro Tools LE run a lot better. I don't understand why users want to rush to the next point oh whatever if their systems had been working fine. One of my clients had that card in a dual G4 and I always had to wait for Pinnicle them to prepare new drivers before I upgraded the OS. The Cinewave video card from Pinnicle, for example, was never ready for an OS update. Before updating any software, especially an operating system, you MUST check to see if your current applications are compatible. Version 18 supports macOS Catalina 10.15, Mojave 10.14, High Sierra 10.13, Sierra 10.12, El Capitan 10.11.I don't understand the anger that some users are exhibiting. Toast 18 has been redesigned as a 64-bit application and is fully compatible with macOS Catalina.
