> Or, the MacBook and MacBook Air can run newer macOS using OpenCore Legacy:

This project is amazing. I just installed Ventura on an Apple Mac mini "Core i7" 2.7 (Mid-2011, “Macmini5,2”). The process went smoothly once I figured out that I needed another old Intel Mac to create the USB boot volume for an even older Intel Mac.

I'm using it to write short stories where my 3 year old kid is the hero (a custom GPT sets the proper context (name, age, location, interest) so the prompts can be short like "a story about learning to read with a new dragon friend")... and doing so bilingually, with each paragraph available in both languages

Maybe 5 years ago, I was in a similar place. I had a particularly embarrassing moment at work when it clicked that I just... didn't know the basics. I was, to use an overused term, "mathematically immature".

So I made a commitment: I decided I would work through Khan Academy math for 1-hour a day for 1 year. I started with pre-K [1] (specifically counting) and watched every video and did every single exercise in order. I focused on mastery. I didn't rush myself, and I did not continue until I felt completely confident in the material. I just did this for a year. I think I go through roughly algebra 2. In my mind, it is critical to combine explicit knowledge (watch videos) with tactic knowledge [2] (do exercises). For example, you need to understand what a logarithm is conceptually but you also just need to do problems to get a feel for it. So this is fundamentally different than learning-by-grazing or just reading a book.

I could go on and on, but let me just say that it changed my relationship to math in a deep way.
