This is an unusual problem.
It had been two weeks since I had been on Catalina when something strange started happening. I will get to the strange bit at the end but the main problem is as follows.
Main Issue
My wifi would automatically disconnect, then periodically reattempt reconnection. As it would keep trying to reconnect the UI would begin lagging. Eventually the computer becomes unusable. The UI literally freezes, barely responding at all. How can wifi affect the system.
Lagging symptoms
- Massive Delay when moving the mouse pointer, feels like I'm dragging a heavy object.
- Force Touch trackpad clicks are out of sync, and there is delay in the haptic feedback.
- General Slowlness and beachballs galore when trying to do anything, even shutdown.
Other issues
- The more you try to reconnect the more the UI lags
- The wifi pane in Network settings stops responding and the text on the buttons turns into this:
What Have I tried to do so far?
- I have turned off ipv6 via
- Have tried deleting the configuration files in
- Repeatedly zapping SMC NVRAM
- Resetting to Factory OS (Yosemite). Although this stage is difficult as the recovery keeps giving me the error -2002F. But after repeated attempts I can get it to download and do the reformat.
- Downgrading to Mojave (I'm Currently on Mojave) but the issue is still present.
- Changing WiFi Bands etc
OTHER INFO
- Strangely this lag also happens sometimes within recovery. Like recovery has a wifi connection and once in a while the recovery would also struggle to get the connection and cause the mouse pointer/UI to lag.
- Preceding this problem I had tried to change the mac's preferred DNS service to Cloudflare or some other other I don't remember but the problem started right after that. Could be related I don't know.
STRANGE PART
The strangest part in all this is that this problem somewhat reduces in frequency if I move to another room in the house, my office in my house is right next to a big building with lots of homes and routers. This building also has a mobile tower on top of it.
How can moving to another location cause my laptop to not freeze so much. Current I am sitting in the corner of my living room and so far so good. Will try and connect peripherals like my DP monitor and midi controllers and see if the issue returns. It isn't gone completely but the WIFI seizures are greatly reduced in frequency
FINAL QUESTION
- Is it possible that Catalina's firmware update is literally screwing over older Macs?
- If it isn't a firmware issue did my card go bad, is there a way to test it before I swap.
- Lastly am I under some sort of Kernel Level attack or some sort of wireless interference or radio hacking or aliens or whatever? As I type this I am sitting in a corner of my house, the issue is definitely less severe here.

This summer, I gave a talk at the Mac Admins Conference at Penn State, focused on Notarization, called The Loyal Order of Notaries. It was a lot of work to put together the talk, and I spent more time on it than I have any talk I’ve ever given. I am proud of the work, but there’s a problem.
I Got Something Very Wrong
46 minutes into the talk I said: “this is good news: whitelisting the Team ID affects the notarization restriction.”

This is not correct.
Whitelisting the Team ID in a Kernel Extensions payload from a User-Accepted MDM does not affect the notarization requirements in the Catalina betas at this time. What I said in the talk was based on my conversations with colleagues and friends, and an conversation I’d had with a member of Apple’s staff, and on my initial results with the first beta of Catalina.
My conclusions were based on the question I asked in that inteview: Will there be a way to whitelist Developer IDs for notarization the same way there is for Kernel Extension loading? The answer was an unequivocal yes.
I assumed that the method for this was the same payload. That has turned out not to be the case in my testing thus far.

So What Now?
I don’t know.
That’s not a very satisfying answer, I recognize. I wish I had a better one.
Here’s what I do know: merely providing a kernel extensions whitelisting of the Team ID of a Developer is insufficient to prevent warnings for packages and disk images signed with that Developer Certificate.
I feel like I blew it.
I had tested this with my Catalina machine, but I realized that the package I was testing with was signed, and with a Developer ID I’d whitelisted, but it wasn’t a unique path or package. I had already installed that package once before, before I’d whitelisted the Developer ID.The LaunchServices Database had a record of the package and the path from where it had come from. It had already exited quarantine, and thus wasn’t passing through the Gatekeeper checks that the talk described, despite having been uninstalled.
How Do I Deal With Non-Notarized Materials?
Catalina’s requirements for notarization on signed packages, signed disk images and unsigned zip files are enforced by Gatekeeper processes, which depend on file quarantine flags. If a package, disk image or zip file arrives via browser download, USB file transfer, or AirDrop transaction, it comes with a quarantine flag. Escaping quarantine means passing a notarization check (online or offline), and a code-signing check, and a check for malicious code as defined by MRT and XProtect.
Or, you can deliver the payload through a non-quarantine method, like curl, or the jamf binary.
These methods are not quarantine aware, and while they do carry some additional ACLs, they do not appear to prevent the installation of packages by Apple-signed Installer, or mount of the image by Apple-signed Disk Utility. That means that tools like Munki or Jamf can continue to deploy software that is not notarized to enterprise machines.
One other consequence of these changes is that it’s not just packages software programs that are affected. During testing, I found a package that is properly signed that delivers Motion and Final Cut Pro templates that also triggered the quarantine warning. They were signed for distribution, but not notarized. They still flagged the quarantine check because they were distributing files. I packaged a sent of fonts for delivery to /Library/Fonts, signed the package, uploaded it to Slack for a colleague to test, and sure enough, quarantined:

If you’re planning for your co-workers to be able to open packages, zip files or disk images that aren’t notarized, you’re going to need to prepare them to right-click on the file, click Open, and then accept the warning that follows.
This isn’t ideal.
Netspot Catalina Beach
This will mean that anything you intend to deliver to Catalina computers will need to either arrive without a Quarantine flag, or be installed by a tool that can receive updates without a Quarantine flag and install them directly.

I apologize to the folks in the room at Penn State, to the organizers of the Mac Admins conference, and to anybody who will see the video. I got it wrong. But I’ll own what’s mine, and we’ll learn more together in the future.
