Windowing Problem

[...] you may [...] be stuck with data containing two-digit year fields. You have tried to get it expanded to four digits at the source, but it simply cannot be done.

In this case, you need to adopt a technique called "windowing". Windowing means taking the two-digit year and applying common sense to determine the century that it belongs in.

Obviously, windowing cannot be used for data that might span a period greater than 100 years. For instance, the birth years of people in the general population. There have always been a number of people living beyond the age of 100, and as health care improves that number can only increase. If you code a birth year as "96", that could be either 1996, which would indicate a two-year-old, or 1896, which could indicate a 102-year-old. For a short time after the year 2000, there will be people alive who were born in three different centuries!

My Hackintosh Configuration Guide/Snippet

Important

These are the steps I followed in order to get Mac OS High Sierra 10.13.6 running in my PC. These may not work (and probably won't) on your machine if your build contains different components (like a different motherboard). This is not a proper guide or tutorial, just a reference for me or for anyone facing issues with a build like mine. You will need to read a bit about Hackintosh in order to get the most out of these notes.

My Build

• CPU: Ryzen 5 3600 (Stock)
• Motherboard: ASUS Crosshair VI Hero - BIOS v7601
