I have an Early 2015 Macbook Pro 13-inch Model that has 6 operating systems manually installed on it (High Sierra, Yosemite, Android x86, Windows, Ubuntu and Kali Linux). As I said, I installed Windows manually, without using the BootCamp assistant.
About 2 weeks ago, I upgraded Windows 8.1 to Windows 10. After that, I reinstalled BootCamp helper, since it was broken after the upgrade. It reinstalled successfully. It was all normal from that point.
However, yesterday I noticed that the Taptic Engine (trackpad) stayed on every time I shut down my computer when it was booted up from Windows 10 (this doesn’t happen when shut down from other OSes). Is this normal behaviour? If not, how can I fix it?
EDIT 1: I have just discovered something strange. If I shutdown Windows using Classic Shell’s shutdown button, the problem happens. But when I shut down using
shutdown -s -t 0, it shuts down the computer and turns off the taptic engine too. I will disable Classic Shell and try to shutdown and tell the results.
