i really want someone to do this on the new i9 macbook.
my macbook can pull off 29 tracks stable, 30 it doesnt chew through the cycle.
CPU is not maxed out... and one core is not even used at all.

Are you sure you are at 44.1 khz?
I will tell you, in istat, i have 8 threads, and Logic is using 650% here.. (max possible is 800%).
With you and the i9, the theoretical max is 1200%. I presumed logic would get close to 1000%
30 tracks is way too low.. No way that makes sense..
Ok, here are the questions to get to the bottom of it
1) Have you applied Apple's thermal patch for the new macbooks?
2) Running at 44k?
3) what is your buffer and process buffer set at?
4) In Logic preferences, are all 12 threads enabled? Does logic performance meter show 12 bars?
There really is a problem with overheating and the new macbooks, unfortunately the macbook chassis can not even come close to dealing with the heat of the i9.. that's why after all the reviews, it's pretty much unanimous advice to just get the base cpu with top ram and graphics.
The i9 will dip under base clock with full load, even with the thermal patch.
My last advice is to try turbo boost switcher which is FREEhttps://www.rugarciap.com/turbo-boost-s ... -for-os-x/
This will keep your i9 at 2.9ghz
It is very likely it will stop ALL overheating.. Considering when my turbo boost is disabled i get 37 tracks, I presume you will get 50 with 6 cores at 2.9ghz.
Please give it a go..
as i showed above, because of heat and fluctuating clock speed, having turbo enabled for multi core tasks that use all cores in a macbook is a pointless waste of heat and shorter processor lifespan.
My cpu has not gone above 80 degrees ever since i disabled turbo no matter what I am doing.
I also now undervolt it 0.80 mv, and it never goes above 75.
Interestingly, if i don't undervolt it, and turbo is enabled, mhx gets throttled at about 94 degrees.
with undervolting, it allows the temp to go to 98 and maintain a higher turbo.. that is way too hot for comfort for me, so I have more or less permanently disabled turbo.
Volta doesn't work on all macbooks but the watts power limiting feature should work as well as turbo enable/disable (yes, volta also allows control over turbo BUT it requires turning off a portion of SIPS and is only a one week trial. Cheap app though).
By the way the one core not being used at all is normal for Logic X.. i have never seen the last core used unless I arm a track to be "live".. It reserves it for that and various tasks.
You will notice if you click on a sculpture track and start playback again, suddenly the last core is used
I think this is all to do with Logic's new "multi thread for record arm and playback tracks" option.
Ok, so i changed Logic's setting to just multi thread for playback tracks.
My test results are identical.. however, now all the "live" tracks are stacked onto one core..
I pressed the R button on three of the sculpture tracks and started playback.. as soon as i hit a midi key you see all three tracks go into live mode, and logic's final core almost full. So.. there you go:)
