I have justed received my boxed Guru from retail store.
After installation (latest OSX), Logic pro 8 didn't recognize Guru. I installed the latest version 1.5.12 and now it does BUT it can't find any sample, kit, pattern or groove.
The folder names are all there but Guru doesn't see any .wav or other extension. The map is set to /library/gurudata/
When I look into the map, the sounds etc are all there, so the installation went fine.
The only thing Guru found were loops, when I clicked one one of them, a window popped up trying to find the file. But I could not click it. When I closed that window I got a message Guru was trying to find the folder and I should direct it. When I clicked "no" (because assigning didn't work) Guru and Logic crashed.
