Re: Apple Catalina Appears to Introduce Massive Jitter - SOLVED! - Update!

FWIW, in this really interesting read about the latest vulnerability released by Project Zero, they talk about AWDL and how if this is in use (AirDrop enabled?) then you're going to get tons of jitter/packet

You can supposedly still use 4.5 4.6 on Big Sur if you do the following but I have not tested it on Little Snotch, works fine for personal software and others ... codesign -dvvv littlesnitch.package name Save the team identifier Boot into recovery mode Open terminal and type the following...

Re: Apple Catalina Appears to Introduce Massive Jitter - SOLVED! - Update!

So after installing Little Snitch and basically denying "trustd" any kind of Internet access, I have been seeing reasonably normal jitter with Bluetooth enabled. It's not that Bluetooth stops scanning, but it's not scanning as aggressively. So after a few minutes, there will be very high

I'm not generally into conspiracy, but as I keep trying to work out the issue I described in this thread, I came across this:     https://sneak.berlin/20201112/your-computer-isnt-yours/ Might explain quite a lot, actually, (particularly at the FAQ section under "When did this start?") and why

Re: Apple Catalina Appears to Introduce Massive Jitter - SOLVED!

Thanks, J. So I did test this a few times as well. The only thing I had enabled (during the first test) in "System Services" was "Find My Mac". Everything else was turned off, and the issue remained. Just to confirm that this was a clean install of Catalina, so the only wi-fi AP in my

Re: Apple Catalina Appears to Introduce Massive Jitter - SOLVED!

Hey Mark, Went through a bunch of tests here. Seems I’ve cleared up the matter on this macOS[1] Big Sur at least by disabling Wi-Fi Networking under “Location Services -> System Services -> Wi-Fi Networking [2]”. It seems at least from perspective that something changed there and causes the

Re: Apple Catalina Appears to Introduce Massive Jitter - SOLVED!

Just an update on this re: the Bluetooth. I had my AirPods paired previously for single use. I don't use them on the laptop (there is some latency), so I prefer the wired earphones. But it seems like Bluetooth was aggressively scanning for them. After removing them from the system, the

Re: Apple Catalina Appears to Introduce Massive Jitter - SOLVED!

Let me jump in and add a bit more information. I am not an RF guy - I stopped playing with radios [and TV] in the days when they used vacuum tubes (yes, really.) Many laptops share radio and antenna resources between WiFi and bluetooth. Bluetooth lives on the 2.4ghz band.  Wifi presently

Thanks for the input, Karl. Hopefully someone from Apple is around here and can get some ideas on how to fix this particular problem set. Mark. On 10/31/20 11:37, Karl Auerbach wrote: Let me jump in and add a bit more information. I am not an RF guy - I stopped playing with radios [and

Hi Mark, I'm running a MacBook Pro (Retina, 15-inch, Mid 2015) with Mojave 10.14.6 (latest). I've always had location services off (including all system services within). I haven't seen any jitter issues on my end. Along with, no matter if I have bluetooth turned on with my wireless mouse and

Re: Apple Catalina Appears to Introduce Massive Jitter - SOLVED!

Heya ! Doug! Yeah I wouldn’t put this on BT either. On the other hand it seems that whether the scheduler is newreno or cubic that this situation persists pasts my previous suggestions. Seems tho that when you put strain on an upload that the jitter gets considerably worse... 90m out of a 100m

Hi all. So I may have fixed this for my end, and hopefully others may be able to use the same fix. After a tip from Karl Auerbach and this link:     https://developer.apple.com/forums/thread/97805 ... I was able to fix the problem by disabling Bluetooth. However, disabling Bluetooth was
