TouchBar not responding to touch after screen replacement

Dear Community,

I replaced the screen of my MBP with this LCD Assembly for Macbook Pro Retina 13" A1706/A1708

The screen works just fine, but the TouchBar does not react to touch anymore. It still reacts and shows the corresponding buttons to the programme I am using at a given moment.

Also notable is, that I cannot find the TouchBar agent in the activity monitor. I tried already to restart the agent in the terminal and reset the SMC. I fear that I ordered a wrong screen or damaged it during the repair.

Would appreciate any tips!

Sadly that leaves the only thing left is when you damaged the display the Touch Bar also got damaged too.

The Touch Bar display is independent of the main screen from a connection perspective to the main logic board. The driver & touch logic is part of it: MacBook Pro 13" Retina (Late 2016-2017) Touch Bar Assembly.

Thank you for the quick answer. Is there a guide (on a similiar device) which shows how to install it?

Sorry we just don't have a guide that walks you through it. I'll warn you this is not as easy as the display changeout as you'll need to remove the display and logic board from the upper case and using a heat gun carefully heat the touch bar as well us solvent to unglue it from the upper case. You can see how difficult this is looking at the Desmontaje de MacBook Pro 13 "Touch Bar. Jump down to Step 15. You'll need to shield the keyboard from the heat as well.

@pestarzt Did you ever figure out what happened and how did you fix? I just replaced the display assembly on my mid-2017 MBP 13 w/Touch Bar and after reassembling the screen worked fine but, the Touch Bar would not respond to touch. It did however, display the commands, options etc. as expected.

@kenlrich - Did you try resetting the Touch Bar? Unlike the display aspect resetting often fixes the touch function. If not time for the same repair.

@danj Thanks for the response... I tried all of the resetting commands with different variations for the process names I found doing a google search. I have 2 of the exact same laptops so I can compare and contrast settings. Interesting that on the one not working the "TouchBarServer" process is not present. the "Control Strip" process is present on both. I also ran diagnostics (option+d on startup).. no issues. Also reset NVRAM and SMC.

Are they running the exact same OS versions and maintenance levels?

- de

@danj - Yes, 10.5.4 Catalina

@kenlrich - OK, Brute force time! Create an external bootable drive with Catalina from the system which has the 'TouchBarServer' process working. Remember you need to have the external setup with GUID - APFS. Using this drive boot up this system using it. Is 'TouchBarServer' process still present? If it is jump to the other system and boot up under it. What happened? You may need to restart the processes.

Hey @roy678, no I could not fix it to this day. Even though I did not try yet what Dan suggested to kenlrich. So far I am using "TouchBarServer.app" which I found somewhere on Github to simulate the touchbar.
