Hi Lupine,
Yes. I had a MBP 15 2018, i7 8th Gen, 32GB RAM. Lovely machine. But...I sometimes got clicks and pops too, with using around 25 - 35 Special Editions instruments (not the Synchron player new Special Editions) and some other libraries together, such as LASS Lite. So not too heavy for it. But still, some issues. I had to up the buffer as 128/256 weren't always stable and still gave me good low latency times.
I would have thought it would have been able to handle all that without any issues at all. To be fair, it did most of the time. But I never felt I got my value for what I paid for it. I since learnt from others here and in general, that laptops aren't great at managing heavier orchestral workloads, even high spec ones. After 3 years of Apple, I realised that I'm paying over the top for an equivalent PC/Windows system and have always been more comfortable with Windows (conversly to most I'd expect).
Anyway, laptops just don't seem powerful enough in comparison to desktop builds unfortunately. So I've just finished building my first PC from using a i9 CPU pre-installed gaming motherbord, adding my own RAM and SSD parts. It works much better. I may get a laptop to use away from the desk or to share the load as I have 2 VEP 7 licenses or even within a master/slave setup. The next laptop it will be one where I can install more RAM and SSD storage in myself later on. Not a MacBook basically.
I did hear about the T2 chip causing issues. I can't remember what it was though. Are there specific T2 chip issues going on with music software?
