1. I have my personal calendar and work calendar. When I'm in school I also have a class calendar and a homework calendar (all day events that start and end corresponding to when assignments are given and due). I also have access to my sister's personal and work calendars because we live together and share a car. she has the same permissions for my calendars with view settings so she doesn't see my work meeting names and vice versa.

2. I use Google Calendar so tasks are their own thing. I do use them for specific tasks that seed to be performed at a certain time or day, but don't require a full event such as taking out the trash or submitting an invoice.

3. It depends. I'm fine with the default public holidays calendar, but you may have different needs.

All good things to think about. Thank you!

My friends are going to get a kick out of this. Thank you!

You're right on both counts, I think. I'll have to double check my pair order.

This is a hackintosh so it's a bit of a mess. The pairs are mismatched in speed, but if I turn on XMP to get it up to the speed of the lower pair (which is supported by the higher) then I get occasional kernel panics in macOS.
