macOS High Sierra 10.13.5 - CPU overload
 

Unfortunately I missed the warning about upgrading. Running Pro Tools Version 2018.7.0 is causing so much CPU overload mishaps. I have to restart Pro Tools every time I get the error message because MIDI tracks are rendered inaudible. And I've been getting the message every few minutes with only one track recorded on a new session. Is there a solution on the horizon?

Impossible to know without system info. Help Us Help You

I would try a clean install of 10.13.3, which is the only recent qualified/supported version of macOS. I have an installer if you want to try it.

Hi Chris,
Here is my system info:

MacBook Pro (Retina, 15-inch, Mid 2015)
Processor: 2.8 GHz Intel Core i7
macOS High Sierra 10.13.5
Pro Tools 2018.7.0
Memory: 16 GB 1600 MHz DDR3
digidesign 003
Glyph GPT50 hard drive
Rocketfish FW800-FW400 adapter with 6-ft cable between hard drive and 003
Apple Thunderbolt to FireWire Adapter - connecting computer to 003

I have trouble shooted till I have no time left to record. It started to happen over time. I actually completed a full demo with 20+ tracks. Near the end of that process I was getting more and more CPU error messages. Now I can't even get through recording a piano track with nothing else in the session. Losing creativity and gaining frustration with each restart.

midi tracks inaudible cause the lost midi connection bug is worse than EVER in 2018.7 and 2018.10. It's embarrassing, to be perfectly honest.

Or do you mean that your cpu overloads and the program can never get back to a state of not being overloaded? That's a weird one, and something i've never experiences.. PT always recovered when playback is stopped and i can juggle tracks around, freeze etc, as needed.

If you see my system info in my sig, i have an identical macbook pro, processor, etc.

If i set my buffer to 128, i absolutely never get cpu spiking, and i have over 500 aax plugins installed.

If i work at 88k or higher, i need to set the buffer to 256. That's my recommendation and what I tell everyone. SO much in PT is fixed if people use the 128 and 256 buffer rule (depending on sample rate).

Yes, when I try to correct the CPU overload, the midi tracks are no longer audible, and I have to restart Pro Tools every time.
