Thanks @Izabela and hi @Mihael!
This is a great question. The short answer is that, yes, the lower spec Mac will work fine with Adobe Audition and my presets. There are a few things to take into account if you want more power of course
Firstly, when I purchased my last iMac I upgraded the CPU to the highest end one possible. I think it was an Intel i7 at the time. This is a decision I regreted as the iMac cooling system simply couldn’t seem to handle the heat of that CPU with the fans whiring up to full almost instantly at any remotely busy task (even multitple tabs open in Chrome). The temperatures ran super hot and it wasn’t a great experience.
After reading around it seems othere (2015 iMac here) experienced the same and it wasn’t a hardware fault. Hopefully Apple have sorted this out by now as I’ve had previous iMac machines that were whisper quiet. Apple also just made an announcement that they’re ditching Intel and developing their own CPUs in house so it may be worth to hold off for more on that.
Watching this video from Linus Tech Tips there is a suggestion Apple may deliberately throttle their current Intel chips so that when the Apple chips come out everyone will go WOW
I’ve gone fully PC now and am super happy however your mileage may vary.
Here’s everything I placed into my new PC (video below). Rembemer, CPU is good for processing all those effects (especially reverb) but you can’t beat NVMe drives for smooth playback and editing!
