terminal
My question is related to this question:
Transparent Background in Terminal?
I have successfully found the menu to change color/opacity. I used the "homebrew" profile. Then I attempted to change the opacity as shown in the answer. However, once I put the opacity at 100% and closed the window, it completely ignored my changes and went back to 90%. How do I actually ensure that my preferences are saved? There is no "OK" or "apply" button on the color menu.
You can add transparency and a blur effect to windows, and you can also set these values seperately for active windows vs inactive windows, making the inactive windows much more transparent for example.
You'll find these settings in Terminal.app Preferences - Settings - Window. Click the colour picker to define them.
In step 2 you copied the original hosts file to a backup location at ~/Documents/hosts-backup (i.e. in your documents folder).
All you should need to do is rename that file to hosts and then copy it to /private/etc/hosts (overwriting the edited file) to undo any damage that you may have done.
However if you only got to Step 3 you may not even have edited the file yet - in which case a reboot should be sufficient.

Clicking once (and only once) on the "color and effects" icon and adjusting the opacity should properly save any adjustments. Double-clicking may have caused the issue.
