The 1.0.3 installer does not install the RTAS plugin properly on Mac. We'll fix that in the next version, but as a workaround :
- Install the original Jupiter-8V version
- Backup the RTAS plugins located in /Library/Application Support/Digidesign/Plug-Ins/Jupiter-8V.dpm (put it on the desktop for example)
- Install the 1.0.3 update
- Put back the Jupiter-8V.dpm plugin in its original folder.
Then, the 1.0.3 plugin should work fine in ProTools.
Best,
Nicolas
