Dual booting an old MacBook Air?

[VirtuallyInsane]

I have an old MacBook Air 11” (Early 2014) with 4GB Ram and 120GB storage.

I partitioned 20GB of that off for a gaming disk, which I never got around to using but I am wondering if it’s possible to turn it into a dual boot system and run something like Mojave onto that 20GB or would it just not run well, because it’s such a small around of storage?

Just curious to know, that’s all. If it’s not worth it, then that’s also alright.

The MBA can run that partition with 12GB to spare, including safari cache
Mojave is a tad sluggish with 4GB in 2023, Sierra night be the lastest and fastest with 4GB
