I still have this problem when I am using Ableton. I already changed the bitrate to 48000 to all devices and also tried multiple latencies. It seems a problem with the audio driver:  HALS_OverloadMessage.cpp:644  index: 15, start: 0xaa780f998d, duration: 0x2b, fault address: 0x10ba8c000, fault pc: 0x1895cfe6c, faulting TID: 0xc20f, fault type: 0x1, PID: 0x1a8    CAReportingClient.mm:537  Sending message { message="{   "HAL_client_IO_duration" = 11961041;   HostApplicationDisplayID = "com.ableton.live";   cause = "PageFaultsOffIOThread,ClientHALIODurationExceededBudget";   deadline = 87596004;   "input_device_source_list" = Unknown;   "input_device_transport_list" = Virtual;   "input_device_uid_list" = "GDAudioDevice_UID";   "io_buffer_size" = 512;   "io_cycle" = 4;   "io_cycle_budget" = 11354166;   "io_page_faults" = 0;   "is_prewarming" = 0;   "is_recovering" = 0;   "issue_type" = overload;   lateness = 33;   "other_active_clients" = "[ { HostApplicationDisplayID_other_client: com.globaldelight.Boom3D, sample_rate_other_client: 48000.000000, io_buffer_size_other_client: 512 }, { HostApplicationDisplayID_other_client: com.globaldelight.Boom3D, sample_rate_other_client: 48000.036378, io_buffer_size_other_client: 512 }, { HostApplicationDisplayID_other_client: com.ableton.live, sample_rate_other_client: 48006.012834, io_buffer_size_other_client: 51", reporters="<decode: missing data>" }

What about Intel macs ? Macbook Pro 2016?

Here I was able to get the exact moment in the logs of when that POPPING appears. I use Ableton Live, i just load a few tracks (nothing too exhaustive actually). But after some seconds pops start to appear and these are the moments in the log !! default 14:01:54.418427+0800 Live HALC_ProxyIOContext::IOWorkLoop: skipping cycle due to overload default 14:01:54.436033+0800 coreaudiod Audio IO Overload thread: 68c1 inputs: '<private>' outputs: '<private>' cause: 'Unknown' prewarming: no recovering: no default 14:01:54.437464+0800 coreaudiod CAReportingClient.mm:508 message { "HAL_client_IO_duration" = 3115172;

What is the location of that app? I dont have it

I have the same problem !!! I couldnt fix it with anything !!
