Problems in Logic Pro X

Hello! My OS X is 10.8.5. My Logic Pro X 10.0.7. I downloaded MG2 for Snow Leopard from the link. When I run the program offline, everything works fine according to instruction number 2. Only the delay upsets. When I use instruction number 1 and turn on Audio Units on the audio track, Logic sees the midi input signal. But the second Software instrument track is silent. He does not see MG2. Tell me what to do, please!

macOS 10.8.5 is not Snow Leopard (10.6)
You need “MIDI-Guitar-2-for-MacOS-10.14-and-older.dmg”

Thank you very much! I will try again.
