Possible SOLUTION to known issue: TR-572 Blurry Waveform Bug (April 2026 Update)

Happy to update that since Jan 2026, I have not had a single crash during a live set.

Equipment:

Hardware:

2021 MacBook Pro M1 Max 14inch (32GB Ram, 1 TB HDD)- no external HDD plugged in
2x CDJ 3000, CDJ 2000NXS2, CDJ 2000NSX, CDJ 900NXS2, in HID mode plugged in via 2x USB C ports
DJM A9, DJM DJM 900 NXS2 (MacBook plugged into DJM via USB C and using DJM sound card)

Software:

What I did:

1. Turned off Multi-Core Processing in Traktor Pro (to optimize GPU usage)

2. Turned off parallel waveforms view to essential view in Traktor Pro (to optimize GPU usage)

3. Set sample rate to 48000 HZ in Traktor Pro (optimal rate for Pioneer DJM)

4. Set buffer size set to 512 MB in Traktor Pro (to optimize CPU/ core audio usage)

5. Turned off Wi-Fi, Bluetooth in Mac OS (to optimize CPU usage)

6. Turned off Pro Motion and made display 60HZ in Mac OS (to lower GPU usage)

7. Set USB "suspend setting" to Disabled in Mac OS

Apple Menu > System Settings
and click
Battery
(or
Energy Saver
on some desktops) in the sidebar.
Click the Options button.
Toggle off "Put hard disks to sleep when possible"
Go to System Settings > Battery (or Energy Saver).
Toggle on "Prevent automatic sleeping on power adapter when the display is off".
System Settings > Privacy & Security
Scroll down to "Allow accessories to connect".
Change the setting to Always or Automatically When Unlocked to prevent them from being "suspended" until you log in.

8. Placed USB Allow accessories to connect to Always in Mac OS

9. Analyze Track Collection for Consistency

10. Restarted MacBook before every set to clear any "Ghost processes."

Will continue to monitor and report findings here.

Very useful report. Thanks.

Is it really necessary to do so many things to a silicon mac?

I thought they just purred with Traktor?

is the blurrywaveform bug/crash related to jogwheels? CDJ and S4?

I use timecode records DVS, 64 samples, and use parallel waveforms and never had this bug happen.

I only have caffeine app to prevent sleep mode when closing the macbook

@leesinthemix yes supposed to be, but this is what it has come down to unfortunately.

@pARty_bOy not necessarily. It has also been reported in internal mode as well: https://www.reddit.com/r/traktorpro/s/qIAlvfkzaw

Also updating no crash on NI S2 MK3, which has also crashed with the blurry waveform bug in the past.
