Hello guys..by when I went to the Mac I'm having many problems, I downloaded more than one version of ableton 10, and unlike the version I used with win, I noticed that there are many things missing, for example in the drum rack, for example the "kidfield, magick drum rack, and other things ... why ??

 

Try creating a new live set, I had a similar problem with Windows (Echo, Pedal, Drum bus missing) and that solved the problem

 

I tried doing as you say .. but nothing! and actually I noticed that there are also audio effects "echo" pedal

 

I do not really understand ... I miss several drum kits

 

because on your old pc you had installed previous versions, and ableton live comes every time with different content. so live 8 had other things, so install old versions to get those kits back , and by the way often you will have installed packs that you are not aware of anymore

 

But if I copy the packs that I had on the windows pc in my mac, can you recover everything?

 

yes you can , as long as it are pure Ableton alp files or ADG or so you can
