New Apple machine with 8th Gen i7 (Mac mini) running badly

Post by gunark » Sun Dec 30, 2018 4:31 pm

Hi all,

I upgraded my 2012 rMBP i7 to a nice new 2018 six core i7 Mac mini, in the hope that those sessions that would put it to the limit will gain some headroom, and the I can run heavier plugins, such as the Acustica ones.

So my setup is: Mac mini 2018 8th gen i7 (3.2>4.6ghz), 512gb inbuilt SSD, 8GB RAM, external USB3 library drive, Focusrite Clarett 2pre connected via Thunderbolt. OS is Mojave, no choice in that, and is freshly installed (i.e. no migration).

Live 10, frankly, runs poorly. I have to set my interface at 512 samples (12.4ms, 23.9 round trip), sometimes 1024 / 2048 samples to stop the pops. Even then it still has pops and crackles on occasion. That's pretty lame for a new machine with a fast interface. I don't know what part is at fault here, the hardware or the software.

In terms of running plugins, I had Massive playing chords followed by Molekular and a big wash reverb effect, and that needed to go from 512 to 1024 to stop glitches. The only other thing loaded was Xenoverb on a send. This seems unusually poor performance. Weirdly though my system's CPU meter (iStat) shows most cores at under 50% CPU at any given time.

I know Live isn't Mojave qualified yet, and I know some people are having issues with T2 based Macs and audio. However I can run plenty in Reaper - even Acustica stuff - and it doesn't crap out nearly as quick.

Anyone else using either the new Mac mini or the 2018 MBPs doing better than me?

…that doesn‘t sound normal…when have you set it up?…maybe the ssd is still indexing?…

Hi gunark,

Any update on your issue?

I'm having issues on the same machine (well, I have 32GB ram and 1tb ssd)....
I drop in one instance of Soundtoys decapitator for example and suddenly my cpu is at 3%. (Decapitator is supposed to be fully supported on Mojave)
Very disappointing as I'd really like to get to work but now it seems there's a whole heap of troubleshooting to do. I'm almost wishing I went for the iMac...
I'm gonna try the Beta version of Ableton and see what happens....

...if you have these kind of problems while using an usb audio interface: there's a problem with apple's t2 chip (on all computers that have it) that makes usb audio drop out or crackle...(there's a long thread about it on the rme website)...solution is to connect your usb interface via a thunderbolt3 hub...

Hi - sorry for the slow update, grabbed a Clarett2pre as I wanted to avoid USB and I know TB should have a ton of bandwidth.

Short answer - no, it's not really better. Even previously fine synths such as Omnisphere are killing it with a the kind of patch I could work with before. I'm running at a buffer of 1024 around 28ms and I'm having to freeze after 2-3 tracks. I don't know if it's Live or the Mac, though Reaper seems better, as does Maschine standalone.

My current track has:
Maschine 2 running a sampled kit
Moog Minitaur (external) - frozen
Omnisphere (frozen)
Ominsphere (not frozen, couple of granular oscillators)
Eventide SP2016 short reverb (return)
Eventide Blackhole long reverb (return)
Ableton Echo (return)
Valhalla Vintage Verb (master bus)
Sonarworks Reference (lightest setting)
I've a Neutron 2 on each main channel but they are switched off.

This lot sits at 35% or so, Omni puts it to 70% and then the glitches come. My activity monitor is as shown:

I'm baffled and worried frankly, I've spent loads on this machine and this software - somewhere, something isn't right.

Hi, did you try to turn off auto setup for date and hour ?

Ah is this to effect the possible glitch issue with the timing in Mac OS that when it updates it may cause the T2 to glitch the audio? I must try it actually, see if it helps. Thanks.
