Hello,
I just installed Max7 and have tried some patches.
Since my installation, all the Max patch files with .maxpat suffix are associated with Max7, whether previously or newly created.
As I am not planning to change my developing environment to Max7 but will stay with Max6.1 for the next while, I tried to restore the file association doing:
OSX (10.9.5) Finder - Get Info - Open With - Selecting Max 6.1.9 - Change All
This process does not restore my original association but it remains Max7.
If anyone knows a workaround, please let me know.
Thanks!
