That’s an old issue (also had it with a 2012 Mac mini). It’s interference from your USB 3.0 device/cable on the 2.4 GHz ISM band. Potential ways to fix the issue: • use a short USB 2.0 extension cable (like this¹ 6″/15cm one) to force the USB connection down to USB 2.0 (not ideal, but guaranteed to solve the problem) • move the USB 3.0 HDD further away from the Mac mini and mouse • try swapping out the USB 3.0 cable for one with better shielding For more information about the issue, see Intel’s white paper titled USB 3.0 Radio Frequency Interference Impact on 2.4GHz Wireless Devices here². ―――――― ¹ — https://www.amazon.com/gp/product/B000E5CYW8/ https://www.amazon.com/gp/product/B000E5CYW8/ ² — https://www.intel.com/content/www/us/en/products/docs/io/universal-serial-bus/usb3-frequency-interference-paper.html https://www.intel.com/content/www/us/en/products/docs/io/uni...
