macOS 10.14 Mojave: Remove Transparency Effect, Encrypt USB, Change Accent Color

macOS 10.14 Mojave is probably one of the most controversial macOS versions to date. It’s left a lot of NVIDIA GPU users with little to no support, users have had to reinstall it because of update issues, and a plethora of other bugs and problems have made it one of the most frustrating macOS updates ever. But if you’re already on macOS Mojave and have successfully skirted major issues, you may be looking for more advanced pointers. In this article, we’ll discuss how to remove the transparency effect, encrypt a USB flash drive and change the accent color in macOS 10.14.3 Mojave.

How to Remove the Transparency Effect

The transparency effect – or, more appropriately, the translucency effect – in macOS Mojave can be a little disconcerting, especially for graphic designers and others working with visual media. If you don’t like it, here’s how to disable it:

From the System Preferences window, go to Accessibility >> Vision >> Display and then check the box next to where it says “Reduce Transparency.” That’s it.

Another way to increase legibility of text and color clarity of visual media, you can try changing the accent color. Continue to the next section, below.

How to Change Accent Color

Until now, we’ve had to be satisfied with Blue or Granite for our accent color on Macs. With the Mojave update, Apple now lets you choose from a range of options. Ideally, if you’re removing the transparency effect, it’s also a good idea to change your accent color to grayscale. Here’s how to do it:

Go to System Preferences >> General >> Accent Color and set it to grayscale or another color of your choice. You should be able to see the changes instantly in the menu buttons, tick boxes and so on. Grayscale gives you better contrast, and it is much less distracting than, say, pink! But if pink is your thing, who are we to stop you?!

Next up is encrypting pen drives.

How to Encrypt a USB Flash Drive in macOS 10.14 Mojave

Insert the USB stick into a port and wait for it to mount. You should be able to see it mounted as a drive in your Finder window, on the left panel. Right-click and select “Encrype [USB Drive Name]” in the contextual menu that appears. In the new window, set a new password for the USB stick and click on Encrypt Disk. You can save the password in your Keychain once the encryption is complete. How long it takes depends on how much data you have in there.


This process only works on Macs, meaning you can’t read the USB drive on a Windows machine. To do that, you’ll need to encrypt it using Disk Utility. Finder uses a different type of encryption that is not compatible with Windows without additional third-party tools, but we won’t get into that.
