Brightness slider issue

[chrismblack21]

My MacBook Pro M3 Pro 14 inch has an issue with this app enabled. It has its brightest setting in the middle of the slider on the 7th setting, almost like it is in half. After that, it goes back down to half brightness and then goes up slightly.

@chrismblack21 Does the newest version of BrightIntosh v5.4.8 (or higher) solve the issue for you?

[chrismblack21]

It did not unfortunately. I can send a video of the issue if it does help.

@chrismblack21 That would be great

Are you talking about the native macOS brightness slider or the one from BrightIntosh?

Same exact issue here, for me its the native slider that doest work.
Interesting thing i just found out, with the BrightIntosh slider at 99% the native slider works perfectly fine but with the BrightIntosh slider at 100% native slider breaks, maxes out at arround 50% and is overall not smooth at all.
@chrismblack21 try setting the BrightIntosh slider to 99% until the issue is fixed u guess :)
@niklasr22 lmk if you need any more info :)
