Touch ID Stopped working on MacBook

You need to reset your secure token.

sysadminctl -secureTokenStatus mlr
sysadminctl -secureTokenOff mlr -password - -adminUser Manamana -adminPassword -
sysadminctl -secureTokenStatus mlr
sysadminctl -secureTokenOn mlr -password - -adminUser Manamana -adminPassword -
sysadminctl -secureTokenStatus mlr

On a Mac, a Secure Token is a crucial account attribute that enables users to perform specific, system-level operations, particularly those related to FileVault encryption and system security. It's essentially a permission that allows a user to manage and decrypt encrypted data on the Mac.
Here's a more detailed explanation:

Purpose:

Secure Tokens are used to authorize users to manage FileVault, which is Apple's built-in encryption feature. This includes enabling and disabling encryption, as well as decrypting the system drive.

MacBook Keyboard Shortcuts to Position Window to Left or Right side of Screen

Refer: https://www.paulsahner.com/posts/window-movement

  • Apple Logo, Upper left hand corner
  • System Settings
  • Keyboard, Keyboard Shortcuts...
  • App Shortcuts
  • Choose "All Applications"

You are going to add two settings by clicking the plus key. I'm using [Ctrl]+[Windows]+[Alt]+[Right Arrow] and [Ctrl]+[Windows]+[Alt]+[Left Arrow] for my settings.

You will use the following menu titles, you need to type these EXACTLY, and copy and paste does NOT work, since it assumes you are setting your keyboard combination.

Move Window to Left Side of Screen
Move Window to Right Side of Screen

Save each setting and click "Done" to complete.

Disable IPv6 from the command line on a Macbook

Run a command through the Terminal app:

  • Open Launchpad.
  • Search for Terminal.
  • Click on the Terminal.app.
  • If your active network is WiFi enter the following command:
networksetup -setv6off Wi-Fi
  • If you are on Ethernet:
networksetup -setv6off Ethernet

To re-enable IPv6, you need to replace setv6off to setv6automatic for Wi-Fi or Ethernet:

networksetup -setv6automatic Wi-Fi 
networksetup -setv6automatic Ethernet
