Bounce doesn't get my mixes right

So i have actually been going around with this problem for quite some time, cause i thought that the only problem was my iTunes that had some minor server disabilities and couldn't play my bounces the way they were made. Until i recently tried to strictly study the deferences from one of my Logic-projects to the same project's bounced wav-file on other MacBook's media players, and in other DAW's etc.

To sum it up - the problem is that no matter which project, Logic doesn't get my mixes and masterings right, the way i mixed and listen to them through the master channel, when i bounce the project. It doesn't matter if i bounce it in mp3, wav, aiff etc., and what the bounce settings is, because I have already tried everything on that area.

Everything should be the same sample rate as well - 44.100kHz

I use a MacBook Pro 13", 2017, but I had the same problem on my old Macbook Pro 13" Mid 2014.

My Logic Pro X should be up to date. V10.4.2

Ask me for more information if it is. 🙂

/Thx in advance
