Fix macOS / OSX White-Washed Display

As part of the display brightness feature of the new OSX Catalina, I’ve noticed my display will sometimes get a bit white-washed in order to provide maximum brightness in settings with lots of light (such as outside).

This feature can come in handy for some, but it also seems to be a bit buggy and can become ‘stuck’ leading to an apparently white-washed, un-saturated display where the colors are all flat and the blacks are clearly not black.

The steps to resolve this issue if your display seems to be stuck in this mode:

  1. Open System Preferences
  2. Navigate to Displays
  3. Click the “Color” tab
  4. Change the “Display Profile” to any other profile.
  5. Change it back to your preferred display profile (Color LCD is default)

Upon changing the display profile, the saturation/contrast issue should be resolved.

Better Key Rates – OSX

Set better keyboard repeat rates with the following commands in terminal. Before running the commands set your Key Repeat and Delay Until Repeat to the fastest options (System Preferences->Keyboard).


#disable special characters when holding keys
defaults write NSGlobalDomain ApplePressAndHoldEnabled -bool false

# normal minimum is 15 (225 ms)
defaults write -g InitialKeyRepeat -float 10.0
defaults write NSGlobalDomain InitialKeyRepeat -float 10.0

# normal minimum is 2 (30 ms)
defaults write NSGlobalDomain KeyRepeat -float 1.0
defaults write -g KeyRepeat -float 1.0

Log out and back in and your keys will be blazing fast. Don’t set them too low or you will have trouble using your keyboard to type in your password (trust me, I tried super low values and almost got locked out). If you re-open or adjust your keyboard settings from the system preferences menu, you may have to re-run these commands (so keep this post handy!)

Dual WiFi Networks on Mac OSX (Speedify with 2 WiFi Connections on a Mac)

Things You’ll Need:

Step 1. Get a USB WiFi adapter from Amazon compatible with OSX. There are many options, but I can be for certain the linked adapter works with the linked drivers (and Speedify)

Step 2. Install the drivers. This will enable a USB-WiFi pane in your navigation bar:

The drivers will also enable the USB Network Adapter in your Wireless Settings Pane:

Step 3. Get Speedify Running
There are many ways to tunnel a connection over multiple networks, but Speedify has made this a super simple task. You can even tether your phone for 3 total tunnels to the internet (Built adapter, USB Adapter, Phone Tether).

I’ll be doing a write-up soon on how this setup performs by connecting to two Coffee shops simultaneously.
