Macbook is using macOS High Sierra but it’s the iMac compatible version

My boss has this MacBook Air (11 inch, Mid 2011) and apparently last year he’s given it to someone to upgrade its os manually since apple doesn’t support this mac anymore and now it’s on macOS High Sierra v. 10.13.6 and everything seems to be running smoothly except there’s one little problem: the OS is the one developed for iMacs and now it doesn’t recognize the trackpad and therefore we can’t change the settings for its trackpad.

There’s no backups of what it used to be before the manual upgrade available and tbh, I don’t really wanna make any big changes to the preferences since it belongs to my boss and I don’t really need more work drama.

Now the question is, how can I find a way to change the trackpad settings without making any big changes to the preferences?
