My other systems had enough inputs and old ports with older slower hardware to connect, but the new iMac simply requires new toys to achieve the simple thing of having a mic for input and headphones for monitoring, and an input for the electric (and semi acoustic) guitar(s). My budget is basically 0, so I am trying to not spend more than I need to, but surely want something that works on usb-c or usb-3, has low latency, and works with macOS Sierra / High Sierra and Logic Pro / Garageband. I've found quite a few things, but i have too many questions, and emailing those companies gave zero results. Whatever I found to seem to work great for audio input that works in the software, is all 350 euro and higher. I am really looking for a simple solution for around 100 to 150 .. Hopefully the macrumors community can assist with some suggestions or 'i use this and it works great'
