If preserving your apps/data is not a concern and you are doing a reinstall do a fresh/clean install. Use the apple boot options/tools to wipe your boot disk and do the install. That's going to be pretty much the minimum unless you want to spend a lot of time figuring out which Apple processes are not necessary for your workflow and are safe to be stopped/removed. That's a challenging task even for experts and is highly not recommended.
Then add programs as you need them.
Run just after the install and save the report. Now you have a baseline as you add additional software.
I ran the Macbook Air using Command (⌘)-R
I did a complete wipe using the disk utility and then fresh install.
Even after a fresh install my Mac is not working as smooth as it should.
The CPU load is high in the skies when I use it.
No unnecessary apps at start up and no softwares to start with except Traktor DJ.
When I was doing with (a fresh install) I had audio drop outs.
Activity monitor showed all bar FULL in overload.
Google search shows that I am not the only one with the issue but no one seems to know the issue cause and solution.
Here's the checkup after quitting Traktor. Oh by the way, my fans are always running on max I realised. AND all of that so sudden, no change to my usual routine.

Run Etrecheck once and it will create a report showing all launch and startup items, then you look over the list and decide what you don't need.
A lot of things showing in Activity Monitor are part of the OS though, and you won't be able to stop them running.
Thanks. Trying to figure out if all the things are necessary. In general I would love to keep the apps to as minimum as it can get and delete all stuff I don't need. 98% of the apps I do not even use that are on my Mac...
