Hello, I have read several threads on here about this same problem and did not want to hijack them, but I also noticed maybe you needed some more information.
Here is what I have found:
I installed the latest version of boxcryptor for mac (_v1). I tried to create a boxcryptor folder in both the local storage, and on my google drive. Both times the folder was created but nothing was in it. The xml file nor the three welcome documents were not created.
I also went back and tried the beta version. This too did not work.
I then installed on a windows 7 box and located the boxcryptor.bc folder on my google drive. This worked and the XML file was generated along with the welcome documents.
I then tried to mount this on my mac, I get the prompt to enter the password (because it can find the xml file) but after entering my password nothing happens.
In console on the mac, I see the following error, when trying to mount, and when trying to create an initial box cryptor folder the error is: Boxcryptor: Launch Path not accessible
I hope this helps, as I would really like to use this program, it seems like just what I need, but I do need it to work on my mac.
I will check this post twice daily if you would like me to try anything.
