I thought so too, but another one didn't fix it for me unfortunately.Might be your PSU. I've been through a similar power issue and it took me quite some time to nail it down to a faulty PSU. If you have a spare one try that. Hope it helps.
Hello @coman05,Hi Casey, all,
Long time lurker, infrequent poster. Huge fan of this thread and community!
Since upgrading to Big Sur and adopting OpenCore I’ve been having a heck of time with Bluetooth connectivity. Bluetooth always “shows up” in my system report and the OS. I can connect devices. But the devices always lose connection after a random period of time. After losing their connection, are totally unable to reconnect. My Hackintosh, built to nearly the exact specs Casey recommends, is housed in a Fractal Design Define R6 USB-C. I’ve found that if I leave a USB device plugged in to one of the front USB 3.0 ports, Bluetooth works much more reliably and only infrequently fails, a minor win of sorts.
After much reading and head banging, I think my issue may be a new weirdness introduced in Big Sur (I didn’t have any issues in Catalina!) and believe it may relate to USB mapping and/or power management. I like to think of myself as relatively tech savvy, but Casey’s guides are much easier for a noob like me to follow than, say, the USB mapping guide on the dortania Github. I’m generally not super clear on how exactly kexts “work” or how to alter boot-related things beyond adding new files to the relevant EFI folder and/or opening my config.plist file in OpenCore Configurator and saving changes. But I’m good at reading! Most of the time.
Any thoughts on what’s causing my Bluetooth issue? Agree it seems related to USB mapping and/or power management? Could you point me to the best guide for someone like me to work through the issue?
Appreciate any help! In case it’s helpful attached please find a screenshot of the “Bluetooth” section of my system report. Very happy to provide additional detail or context.
Which Bluetooth devices are you using?
Do they disconnect randomly?
Could it be a signal attenuation issue? Have you considered using an outboard antenna instead of the directly connected antennas?
Do you have other Bluetooth HIDs (HID = human interface devices)? Apple Magic Mouse and Magic Keyboard, unfortunately, lose most of their magic on Hackintosh. We recommend Logitech wireless mice and keyboards that use the Logitech Unifying receiver. These devices work in BIOS, in OpenCore Picker, and of course in MacOS, Linux, Windows, everything under the sun.Hey Casey,
Thank you so much for the response! Answers below. Appreciate any other guidance or recommendations you may have.
Only two: a Magic Keyboard and Magic Mouse.
It does feel random, but the disconnection seems correlated to having devices plugged into one of the front USB 3.0 ports. I nearly wrote my bluetooth works "flawlessly" whenever I have something like a USB mouse plugged into one of them, devices working for days on end and even to sleep/wake the machine, but it does still randomly drop from time to time even when I have a USB device attached, though I'm sometimes able to reconnect bluetooth devices after that happens. If I have no USB devices attached, which is my usual and preferred setup, bluetooth devices typically connect and work on startup, but then randomly lose connection after a short period of time ranging from 1-4 minutes, and like I said originally, are totally unable to reconnect after that happens.
Pressing Shift-Option while clicking the Bluetooth icon in menu bar will reveal an extended window as shown below.Maybe? I don't have an outboard antenna to troubleshoot this with, but I would note that I didn't have this issue in Catalina with Clover, so it feels unlikely to be the cause. If it's helpful context, my bluetooth mouse and keyboard are a mere ~6 feet from the antennas on the back of my machine. That said, there's a few other bluetooth devices nearby -- namely a PS4 Pro and Sonos. But the location of all these devices hasn't changed since I made the Big Sur leap, and I had no problems back in my Catalina/Clover days. If you think this could be the issue and I should troubleshoot it, I appreciate any specific recommendations you have for an outboard antenna.
|-30 dBm||Excellent||Max achievable signal strength. The client can only be a few feet from the AP to achieve this. Not typical or desirable in the real world.|
|-67 dBm||Very Good||Minimum signal strength for applications that require very reliable, timely delivery of data packets.|
|-70 dBm||Okay||Minimum signal strength for reliable packet delivery.|
|-80 dBm||Not Good||Minimum signal strength for basic connectivity. Packet delivery may be unreliable.|
|-90 dBm||Unusable||Approaching or drowning in the noise floor. Any functionality is highly unlikely.|
