Effortlessly Manage Your MacBook’s Power Settings with a Simple Bash Script

I was just looking for a way to quickly switch my power settings on my MacBook, especially when working on battery and needing to keep my computer awake for extended periods. As many MacBook users know, constantly toggling between power management modes can be a bit of a hassle, particularly if you’re someone who frequently switches from being plugged into relying solely on battery power. This is where I found a need for a more streamlined approach.

In search of a solution, I crafted a Bash script that provides a hassle-free method for switching between two power management schemes: “Normal” and “Never.” The “Normal” setting aligns with my everyday usage, allowing the computer to sleep after a certain period of inactivity, whereas the “Never” option keeps my MacBook awake indefinitely, which is perfect for those long stretches of work where you can’t afford the computer to sleep or start the screen saver.

The script utilizes the pmset command, a powerful tool in macOS for managing power settings. By running this script, you can easily toggle between these two modes with just a simple command, saving you the time and effort of manually adjusting settings in the System Preferences every time your work situation changes.

However, it’s important to note that this script requires administrative privileges to execute. This is because changing power management settings affects the entire system, so running the script with sudo is necessary to ensure it has the needed permissions.

Despite this need for elevated privileges, the script provides a straightforward and convenient way to manage your MacBook’s power settings. Whether you’re in a meeting, working on a long train journey, or just don’t want your MacBook to sleep while downloading large files, this script is an invaluable tool.

To conclude, this Bash script has been a game-changer in managing my MacBook’s power settings. It’s a simple yet effective solution for anyone looking for more flexibility in how their MacBook uses power, especially when switching between different working environments. I encourage you to try it out and see how much simpler it can make your workflow. And as always, I’m open to feedback and suggestions for further improvements!

Elevate Your Flight Sim Experience

Quick Access to Real-World Airport Data with AppleScript

Welcome, flight sim enthusiasts! If you’re a fan of immersive flying experiences in games like Microsoft Flight Simulator 2020 or X-Plane, you know how crucial accurate airport information can be to enhance your virtual flights. Today, I’m thrilled to share a simple yet effective AppleScript that can elevate your flight simulation experience. This script enables you to quickly pull up detailed airport information from FlightAware just by entering an ICAO airport code. Ideal for virtual pilots who want to plan realistic routes or explore new airports in their simulator, this easy-to-use tool seamlessly integrates real-world aviation data into your flight sim setup. Join me as we dive into how you can create this handy script on your Mac, blending the lines between simulation and reality for a more enriched flying experience.

-- Start of the script
tell application "System Events"
    -- Prompt the user to enter the airport code in ICAO format
    display dialog "Enter the Airport code in ICAO format (e.g., KLAX, KJFK):" default answer "" buttons {"Cancel", "OK"} default button "OK" with icon note
    -- Store the user input in a variable
    set airportCode to text returned of result
    -- Check if the user entered a code
    if airportCode is equal to "" then
        display dialog "No airport code was entered. Please try again." buttons {"OK"} default button "OK" with icon stop
    end if
end tell

-- Construct the URL using the provided airport code
set baseURL to "https://www.flightaware.com/resources/airport/"
set fullURL to baseURL & airportCode & "/IAP/all/pdf"

-- Open the URL in Google Chrome
tell application "Google Chrome"
    -- Check if Chrome is running, and start it if not
    if not (exists window 1) then reopen
    -- Open a new tab with the URL
    open location fullURL
end tell
-- End of the script

After copying the AppleScript above, open the Script Editor on your Mac, which you can find in the /Applications/Utilities folder. Paste the script into a new document. You can run the script directly from the Script Editor to test its functionality. Once you’re satisfied with how it works, you can easily convert it into a standalone application. To do this, go to the File menu in Script Editor and select ‘Save.’ In the dialog box that appears, choose a name for your application, and importantly, set the File Format to ‘Application.’ Save it to your desired location. Now, you have a fully functional app that you can launch with a click! This app will prompt you for an ICAO airport code and automatically open the corresponding FlightAware page in your browser. It’s a handy tool for flight sim enthusiasts, pilots, or anyone interested in aviation, and a great example of the practical uses of AppleScript on your Mac.

In conclusion, this simple yet powerful AppleScript is more than just a quick way to access airport codes and charts; it’s a bridge between the real world of aviation and the virtual skies of flight simulation games. By seamlessly integrating real-world airport data into your flight sim experience, you’re not only enhancing the realism of your virtual flights but also gaining valuable insights into the intricacies of airport layouts and operations. Whether you’re meticulously planning a virtual flight in Microsoft Flight Simulator 2020, exploring new destinations in X-Plane, or just curious about aviation, this tool brings a wealth of real-time information to your fingertips. It exemplifies how a small script can significantly enrich your gaming experience, making every takeoff and landing more authentic and informed.
