From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Apple very likely applies specially tweaked DSP. They're very very good at that.
You'd have to replicate that using something like Easy Effects. Play around with the EQ and see what you can do.
It could also be a bad driver in which case you probably can't do anything about that.
Hello, I don't think its a driver issue but its more of tweaking issue.
Is there anyway I take make an EQ based on the audio output on macos? I don't think my ears are good enough to remember the sound output on macOS for me to then replicate in Linux when I switch over
That's an interesting thought and you could potentially even do that using commodity hardware.
You could create a sound file which first plays a few short beeps for synchronisation and then does a sweep of the full frequency range. You'd then play that file back in macOS and in Linux at the same volume and record it with a mic in a fixed position.
Then you'd take the two recordings, line them up using the synchronisation beeps and compare the amplitudes of any given frequency. From that difference you could infer the EQ you'd have to add on Linux to get the same frequency response as macOS.
I don't know how exactly you'd do the last step but it should at least be possible.
Mic quality (beyond a very basic point) or colouring should be an issue since you'd have the same mic frequency response in both tests and only care about the difference.
