Have you bought a Mac Mini or MacBook but don't want to use the thin membrane keyboard or pay for the expensive official keyboards? 

Found a mechanical keyboard you love but noticed it doesn’t come with a dedicated Mac layout? No worries! As long as it’s a keyboard, it can generally be used with a Mac — you just need a few settings adjustments to make everything run smoothly.

How to Set Up Windows Layout Function Keys on a Mac

 | Open the Settings menu, select "Keyboard," and then click "Keyboard Shortcuts."

 | Scroll down to find "Modifier Keys" and choose the name of the keyboard you want to modify.

 | Click "Done" and test if everything works correctly.

When connecting an external keyboard to a Mac for the first time, the Command and Option keys may behave differently, so you’ll need to remap them.

The DF98 mechanical keyboards also support key customization, allowing seamless switching between Windows and Mac systems, truly delivering a one-key dual-system experience!

When manufacturers produce keyboards, the mainstream keycap production methods currently include laser engraving, dye-sublimation, and double-shot molding. So, what are the differences between them?

 Uses a laser to etch onto the surface of pre-made keycaps.

 Budget keyboards, office membrane keyboards

 Uses high heat to vaporize dye, which then penetrates the PBT keycap material.

 Mid-range keyboards, PBT keycap keyboards

 Commonly known as molded keycaps, where two types of plastic are injected together to form a single piece. The legend is a separate colored plastic, not printed or engraved.

 High-end keyboards, backlit gaming keyboards

Affordable Double-Shot Keyboards – GD Series Mechanical Keyboards

 mechanical keyboards from darkFlash offer top-tier PBT material and premium double-shot molded keycaps. Who says a budget-friendly keyboard can’t also be durable?

When manufacturers produce keyboards, the mainstream keycap production methods currently include laser engraving, dye-sublimation, and double-shot molding. So, what are the differences between them?



Production Method｜Laser Engraving

Process: Uses a laser to etch onto the surface of pre-made keycaps.

Pros of Laser Engraving:





Lower price point and shorter production time



Low technical barrier; users can pay extra to have laser engraving added after purchase

Cons of Laser Engraving:





Legends may fade after extended use



Engraved areas can feel rough to the touch



Light-colored symbols make it harder to use in low-light conditions

Typical Usage: Budget keyboards, office membrane keyboards







Production Method｜Dye-Sublimation

Process: Uses high heat to vaporize dye, which then penetrates the PBT keycap material.

Pros of Dye-Sublimation





Finer and more delicate font appearance



Mainly used with PBT keycaps, which retain their durability, resistance to wear, and oil resistance

Cons of Dye-Sublimation





Cannot be used for transparent keycaps



Less effective on dark-colored keycaps

Typical Usage: Mid-range keyboards, PBT keycap keyboards







Production Method｜Double-Shot Molding

Process: Commonly known as molded keycaps, where two types of plastic are injected together to form a single piece. The legend is a separate colored plastic, not printed or engraved.

Pros of Double-Shot Molding





Legends don’t wear off over time



Best color and backlight compatibility



Premium production method that results in precise and durable keycaps

Cons of Double-Shot Molding





Requires custom molds, which increases development cost



Higher product price

Typical Usage: High-end keyboards, backlit gaming keyboards

How to Pair the GD Series Dual-Mode Keyboard with the 2.4G Wireless Receiver

Your PC works hard—whether it’s powering through work tasks, running games, or keeping you connected. But while we rely on our computers every day, cleaning and maintaining them is often overlooked. 

One of the biggest hidden threats? Dust. It builds up over time and can seriously impact performance and even damage your hardware. Let’s break down why regular cleaning is important, how often you should do it, and the best way to safely clean your PC.

Dust might not seem like a big deal, but inside your PC, it’s a different story. Dust buildup can block airflow, causing your system to overheat. When that happens, your CPU and GPU may throttle their performance to stay safe—meaning slower speeds for you. In extreme cases, it can even damage parts permanently.

Performance Drops, Hardware Risk, and a Shorter Lifespan

When fans and vents get clogged with dust, cooling becomes much less efficient. That means higher temperatures, louder fan noise, and increased wear on components. Plus, dust on the motherboard, graphics card, or RAM can lead to static discharge, corrosion, or even short circuits.

Shut down your PC and switch off the power supply. Unplug everything before you open the case.

Most cases have dust filters on the front, top, or bottom. These are easy to remove—some slide out, others are magnetic. You can rinse them with water or wipe them with a damp cloth. Just make sure they’re completely dry before reinstalling.

Remove the side panel carefully. With your compressed air can held upright, blow short bursts of air to clear dust from top to bottom. Focus on fans, heat sinks, and vents.

Use a soft brush to get stubborn dust off fan blades and heatsinks. It helps to hold the fan blades in place while using compressed air so they don’t spin wildly.

5. Be Gentle with the Motherboard and RAM

These parts are delicate. Use short bursts of air only—don’t brush them directly.

A microfiber cloth is perfect for wiping your hard drives, SSDs, and any other visible areas. Use compressed air to clean the PSU vents too.

It depends on your environment and how heavily you use your computer, but here are some general guidelines:

Keeping your PC clean isn’t just about looks—it makes a real difference:

What You’ll Need





Compressed Air – This is your go-to tool. It blows dust out of tight spots without you needing to touch anything.



Soft Brushes – Great for gently loosening dust in fans or corners.



Microfiber Cloths – Ideal for wiping off surfaces without scratching them.







Step-by-Step: How to Clean Your PC

1. Turn Everything Off

Shut down your PC and switch off the power supply. Unplug everything before you open the case.



2. Start with the Dust Filters

Most cases have dust filters on the front, top, or bottom. These are easy to remove—some slide out, others are magnetic. You can rinse them with water or wipe them with a damp cloth. Just make sure they’re completely dry before reinstalling.

6. Wipe Down Other Parts

How Often Should You Clean Your PC?

It depends on your environment and how heavily you use your computer, but here are some general guidelines:







Every 3 to 6 Months is a good rule of thumb for most users.



If you have pets, smoke indoors, or live in a dusty area, aim for every 2 to 3 months.



If you’re a heavy gamer or use your PC for demanding tasks, clean it more often due to higher heat output.



For light users in clean environments, cleaning twice a year is usually fine.







Why It’s Worth It

Keeping your PC clean isn’t just about looks—it makes a real difference:





Better Performance – Lower temps mean your system can run faster and more efficiently.



Longer Lifespan – Less heat and dust stress mean your parts will last longer.



Quieter Operation – Clean fans don’t have to work as hard, which cuts down on noise.

A little maintenance goes a long way toward keeping your system running smoothly, quietly, and for years to come.
