I have tested Alice 2 And Alice 3 and Catalina and this is what I found.<br class="">
<br class="">
Alice 3 seems to run without any problems.<br class="">
<br class="">
The first time I ran Alice 2 it hung up. But after I restarted the machine, Alice 2 was able to run. But I found on my machine that the File Open directory no longer allowed me to navigate through my computer’s file system to locate and open Alice projects. <br class="">
<br class="">
I believe that this has to do with Catalina’s increased security measures, and that there is a preference setting that will eventually correct this. We are still tracking down exactly what that setting will be.<br class="">
<br class="">
I found double-clicking on any Alice 2 project file from the Finder of the computer will open the project in Alice 2. If this does not work the first time, you may have to right-click (Control-click) the project and select the Open With option. After you identify Alice 2 as the app associated with the file, the system should remember that .a2w files are opened with Alice 2.<br class="">
<br class="">
We will be interested in hearing what anyone else havs found, or of any other issues you have identified.<br class="">
<br class="">
We will keep you posted.<br class="">
<br class="">
Thank you, and all the best,<br class="">
