Touch ID not working on MacBook Pro M1 Max after Tahoe 26.6

I have seen some similar reports where Touch ID stops responding after a macOS update, although I have not seen enough confirmed cases to say that macOS Tahoe 26.6 is definitely the cause.

Based on your description, the most important detail is that the Touch ID enrollment screen does not detect any finger input at all.

When a fingerprint is not recognized because of a dirty sensor or a finger placement issue, the system usually responds and asks for another attempt. A completely unresponsive enrollment process suggests either a failure of the Touch ID service or a problem with the Touch ID sensor communication.

Since you have already restarted, tested multiple fingers, checked Recovery mode, and run Apple Diagnostics, I would try one more software step before assuming hardware failure.

Boot into macOS Recovery and reinstall macOS Tahoe over the existing installation without erasing the disk.

This can replace damaged system components while keeping your data intact:

If Touch ID still does not respond after a reinstall, I would be suspicious of the Touch ID sensor assembly itself.

The power button can continue working even if the fingerprint sensor portion has failed, so a working power button does not rule out a Touch ID hardware issue.

One additional test would be useful: after booting into Recovery, does the Mac ever ask for or accept Touch ID authentication?

If Touch ID is completely unavailable even in Recovery, that points more toward hardware. If it works in Recovery but not in the normal macOS environment, that suggests a software or security subsystem problem.

Apple also documents Touch ID troubleshooting here:

The 26.6.2 update fixed the problem for me. Touch ID is working again. Thanks Apple!

Hi everyone,

I’m having an issue with the Touch ID sensor on my MacBook Pro (M1 Max) after updating to macOS Tahoe 26.6.

Before the update, Touch ID was working normally. Since updating, the power button still works, but Touch ID no longer detects my finger at all.

The issue appears to have started only after updating to macOS Tahoe 26.6• .

Intel vs M-series... I see now (M1 Max)

On an M-series—A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

certain system caches get cleared and rebuilt

Login and test. Reboot as normal and compare your results.

This is very concerning ..i thought apple devices last decades ..but i think i might reconsider investing so much money into Mac now ..already my motherboard has been compromised within an year even after replacement i got these issues after 2 years and now i dont even have Apple care.. and

"Decades" would be a long time (though I do have an iPod Dock Connector from 2003 that still works fine, but can no longer be synced with modern Macs because FireWire is fully deprecated).

How to reach out to @Apple software Team to help please fix this?

The only way to reach out to the software team is via the Product Feedback pages, but Apple will not respond to submissions. Instead, you may want to contact Apple Support:

Same issue - touchID failure right after upgrade. Apple did this to my old Mac Pro - upgrade torched the bios. My M1 Max with 64GB is still fast enough for everything I do. I am not buying another MacBook.
