CNC a hole in the lid, would it improve bluetooth connectivity?

The Mac mini has been plagued with bluetooth issues for a number of years. With many people suggesting that the thick alloy case being part of the issue.

If one was to CNC a large opening at the top of the case, and replace the removed alloy with a perspex cover. Do you think that could improve bluetooth connectivity and its related issues? Or is it just a case of poor quality control when it comes to Apple Bluetooth controllers?

Sometimes Apple makes a mistake, here on iFixit we've called them out a few times! This is not one of those cases. The design is sound, the placement of the system and/or what you have around it is your issue.

So NO! Altering the case won't help you here and all you'll do is make a nice case a pile of junk!

So let's refocus on its placement, do you have a metal desk or shelving which you have the system sitting on? Do you have metal surrounding the system in any way?

Here's the location of the Bluetooth Antenna

As you can see its what you have the system sitting on that needs to be looked at!

Modifying the Mac mini by CNC machining a large opening at the top of the case and replacing it with a perspex cover could potentially improve Bluetooth connectivity, but it's not a guaranteed solution, and there are several factors to consider.

The thick alloy case of the Mac mini can indeed interfere with Bluetooth signals to some extent, as metal can block or reflect wireless signals. Creating an opening and replacing it with a transparent material like perspex (acrylic) can allow Bluetooth signals to pass more freely, potentially enhancing connectivity.

However, it's important to keep in mind the following:

  1. Warranty and Risk: Modifying your Mac mini in this way may void your warranty. Apple typically doesn't support or endorse such modifications, and you risk damaging the device if not done correctly.
  2. Skill and Precision: CNC machining requires skill and precision. If not done accurately, it could damage the Mac mini or compromise its structural integrity.
  3. Other Interference: Bluetooth issues can also be caused by other electronic devices, interference from Wi-Fi networks, or even software-related problems. Modifying the case won't address these potential issues.
  4. Software Updates: Apple occasionally releases software updates that can improve Bluetooth performance. Before attempting hardware modifications, ensure your Mac mini's software is up to date.
  5. Third-Party Solutions: Consider exploring third-party solutions like USB Bluetooth adapters or external Bluetooth antennas that can be attached to the Mac mini to potentially improve connectivity without physically modifying the case.

In summary, while modifying the Mac mini's case to improve Bluetooth connectivity is theoretically possible, it comes with risks and uncertainties. Before attempting any hardware modifications, it's advisable to explore other solutions, ensure your software is up to date, and, if necessary, consult with professionals who have experience in modifying computer hardware.
