Touchbar Issue on MacBook Pro 2026-09-06 02:26:53.851 system_profiler[8050:71452] hw.cpufamily: 0xda33d83d

i’m unclear which developers you are referring to here. This is a user-to-user forum. Apple may or may or read postings around here, and only seldom replies.

TouchBar issues might be a third-party app, but more commonly mean the TouchBar hardware or bridgeOS is malfunctioning; bad hardware.

Try starting your Mac in Safe Mode, but this case seems rather like failing hardware. Starting in Safe Mode shuts off most third-party apps, in the off chance that some add-on app is getting tangled. But this is likely headed for a discussion with Apple Support, and potentially a repair.

Touchbar Issue on MacBook Pro...

I have a bug from System Tahoe: that touchbarServer is not appearing after turning on my MacBook Pro M2 and there is no option for touchbar settings from keyboard settings. But I must restart my MacBook to show up again with my touchbar on the keyboard settings. Please fix that issue in the next upgrade of System Tahoe 26.6.2 to 26.6.3.

I look forward to your answer and feedback.

Thank you

re: Touchbar

You do not say if this is Intel mac or M-series mac...? As you can imagine they are not the same.

For Intel try both—

resetting the System Management Controller Reset the SMC of your Mac - Apple Support

resetting NVRAM/PRAM Reset NVRAM on your Mac - Apple Support

for the SoC M-series —

A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

no resolve might suggest a hardware as mentioned above.

In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment

Make an appointment for a "hardware issue"

Genius Bar Reservation and Apple Support Options - Apple

Outside the USA

Contact Apple Support - Apple Support

There have been NO pervasive reports of issues like that reported here.

That suggests you likely have a unique problem.

Your problem could be caused by a defect in your specific sample of the product, or it could be caused by your exact MacOS plus installed modifications, or a previously unseen interaction between the two.
