Macbook Pro (Retina, 13-inch, Mid 2014)
Processor 2.6 GHz Intel Core i5
Memory 8 GB 1600 MHz DDR3
Graphics Intel Iris 1536 MB
OSX Mojave Version 10.14.3
My screen broke, so I bought this replacement screen and fixed it myself.
Everything seems to work fine except that my brightness stays at max and won't adjust, unless I put my laptop into "sleep" mode after a reboot.
This problem has persisted since
OSX High Sierra, so I don't think Mojave has anything to do with it. It has also persisted across multiple OS re-installations.
Also note that the problem doesn't exist when using windows 10 BOOTCAMP, and seems to only happen when using OSX.
What is the cause for this bug and what can I do to troubleshoot this? Is this a known issue?
Any advice and/or links to related topics would be appreciated!
I am able to press the brightness keys (F1 and F2) and the small popup window shows up (shown below). Unless I put my computer in "sleep" mode first, changing the brightness has no effect on the brightness of the computer, despite it indicating that the brightness level is changing.
