Any tips to improve Mac Mini Performance?

I have a 2018 Mac Mini, 6 core i7. I bought this after my 2013 iMac died. Despite this being a band new, more powerful machine it does not perform anywhere near as well as my iMac used to. I have to crank my buffer size right up to 1024 to the point where I can’t actually play anything in time and I have to make my resolution so low. I have done all the things that people suggest like turning off date and time sync, reducing transparency etc but I am still struggling with this machine. I have constant errors with sync where it says logic has detected conflicting sample rates and I am confused why I am getting all these problems from a brand new machine.

A more conventional check for the machine health, just to be sure there are no problem with software or hardware other than DAW ? Like a check of all the parameters of the Activity Monitor to see if anything is strange, run the hardware diagnostic, and so on. You never know, it may helps ...

For me, the shared-memory design of the built-in graphics controller seemed to have a surprisingly large effect on DAW performance - but I've also got two 4K screens, which probably ramps up the pressure on how much main memory gets hammered even by things that don't use that much in the way of graphics processing.

I've got an eGPU on mine (Blackmagic Radeon) and that has helped with buffer settings etc. I'm hesitant to recommend that off the bat but there may be ways to test whether it's a GPU-memory conflict that's giving you problems.

How are thermals? You might experience a lot of throttling if it's cooking. Using external ssds is the only thing I can think of without destroying it lol.

My six-core Mini is silent, except when running geekbench and the Logic benchmark tests (at Gearslutz)

My average sessions are 30-50 tracks.

An eGPU can help performance when you have multiple displays.

I installed 64GB of OWC Computing Ram in my new Mac Mini. I don't think it's running entirely smoothly i.e. when I quit logic I get the beach ball for a couple of seconds. I'm also not sure that the fan is triggering when it should, so I've installled Macs Fan Control, so at least it's not overheating. Has anyone had similar issues and any suggestions for fixes. I ran the mac system checker and it doesn't say there is anything wrong, but I'm not so sure ? Thanks very much

I had exactly the same issues with my Mac Mini 2018 (same specs) for almost a year. Then I found the solution: Because this machine has no dedicated graphics card, the cpu performance changes massively depending on the resolution settings in the display preferences. If you choose "Default for display", you get full cpu performance. But when you choose a scaled resolution, then you run into all that problems as described above.

Same here. Problem is the integrated graphics. For me though, using an external GPU didn’t improve anything, so I returned it.

And, as mentioned above, HiDPI scaling massively adds to the problem.

I find it unbearable to work at the default resolution, can’t see everything I need to see and it’s all way too big. But will have to do this when recording or printing.

I’m using Macs Fan Control to increase the fans as it’s stupid that it defaults to barely using the fan at all

Default resolution depends on your monitor. I found the default kinda big on my 27 monitor so I now use 3008 x 1692 (Non Retina). I use full 4K on my 55 inch TV Monitor.
