The best damn AutoLayout guide I've ever seen

Edit Feb 4 5:16 PM: Skip to the bottom if you just want the article

It has been brought to my attention that rehosting someone else's content without asking them — even if you link to the original content — is not exactly polite. I did not ask the author before I rehosted his article, and while I feel I should have known better than to that, it just didn't occurr to me. It's not exactly plagarism, but it's still wrong on some level. I have reached out to him now about hosting it here publically, and if he says it's alright, I'll put it back.

You can find the original article here, on his site, and on his Medium page.

lsof -i :19433 #if you are running Chinese version of Zoom (Zhumu) check this port out
kill -9 PID #kill the server - insert PID number you will find
rm -rf ~/.zoomus/ #remove zoom server from your Mac

Automatic negotiation of a captive portal: connect to icomera wifi in CD trains without having to jump through hoops.

How to Bootcamp / Dual Boot Windows 10 on a mid-2011 iMac using USB

How to Install / Bootcamp Windows 10 on a mid-2011 iMac using USB

Apple has released support for bootcamping Windows 10, but only on 2012 Macs and later. Despite not being supported. it is possible to install Windows 10 on earlier iMacs and it seems to run quite well.

IMPORTANT: Unplug all external and physical hard drives (where possible) that you won't be installing to to avoid accidentally erasing them. Also make note of which drives and partitions remain (e.g. System and Storage hard drives), and be super careful to not erase the wrong one.

RECOVERY: If you nuke your machine, restore your time machine backup. Instructions here.
