Sonar Producer is Windows only.
The only version of Sonar that can run on a Mac is a severely cut-down and basic version that is really at best an alpha or early beta version of a product that was advertised but never developed beyond that. If you can even find it to download.
Forget Sonar on a Mac, unless you install Windows on the Mac using Boot Camp. The various virtual systems like Parallels aren’t fast enough to run SOnar or any other Windows DAW without a great deal of latency (at best).
My advice is on a Mac, try Logic Pro. It’s inexpensive as DAWs go and pretty powerful.
