    Hello!

    I just noticed under About This Mac > System Report > USB > iBridge Bus that there seem to be new components showing up for the 2019 MacBook Pros that weren't there on the 2018 MacBook Pro. Could anyone with a 2018 MacBook Pro confirm that they do not see them?
    I don't remember seeing under the iBridge Bus "Touch Bar Backlight & Display, Ambient Light Sensor and Apple T2 Controller".

    I have highlighted them in the attached screenshot! Screenshot 2019-06-08 at 01.46.50.png

    Very possible. There is the same number of items, and "iBridge ALS" could stand for "iBridge Ambient Light Sensor".

    Can you please check something else on your 2018? I remember that it used to say "20V 3A" underneath my MacBook where the regulatory markings are. Is that correct?

    On the 2019 it says "20.3V 3A".

    EDIT: I looked at the 2018 iFixit teardown and it was indeed 20V at 3A.

    It looks like Apple has made a few changes to the 2019 model besides the keyboard and a small bump in CPU speed. I wonder what else...

    If you look at your MacBook Pro Power Supply/Charger (I understand that you have the 13") there is written the working Voltage and Amps spec in the label, the same is written in the back panel of your MBP. Infact in my power supply there is written "20.2V 4.3A" and the same is written in the back panel of my MBP 15.

    Apple sells 87W charger for 15" and 61W for 13":
    20.2V x 4.3A = 86.86W
    20.3V x 3A = 60.9W

    What is written in the label of the 2018 MBP 13" charger?

    My 2018 13" has 20.3V 3A on the charger & the base. The Touch Bar stuff is indeed named differently though.

    I have both chargers that came with the 2018 and 2019 13" MacBook Pro, and they're both 20.3V 3A.
    But interestingly, under the 2018 it said 20V at 3A, not 20.3V.

    That weird! I wonder if maybe it was an error when they wrote "20V 3A" instead of "20.3V 3A", and they fixed it later on the 2018.
