This is the most bizzare problem. My Macbook slows to a crawl when WiFi is enabled. I'm not talking about internet speed, that is fine. But simply launching or using apps becomes extremely slow. Apps will bounce on the dock for 10 minutes before they load.

As soon as I turn off Wifi, everything goes back to normal.


OSX 10.15.7, 16 inch MBP.


EDIT: here is cause and workaround:

I'm having the same problem! Looking the activity monitor it seems to have something to do with creative cloud. But my attempts to disable it have been unsuccessful so far.

Also, referencing another thread, I have not updated to 10.15.7

OMG i thought i was the only one!!!?? What in the world is going on? How do we fix this? i thought some application on my computer was causing it and tried all sorts of things, i noticed that "Softwareupdated" is using a large amount of cpu power in the background in activity monitor

Is it possible Apples severs are so overloaded from everyone upgrading and downloading Big Sur that some Apple background process is overloading the CPU of our Macs? I’m personally staying on Catalina and have no intention of updating but how in the world would this be causing such an issue on our Macs?! I’m clueless as to what is actually going on right now, the MacBook is nearly unusable if I’m connected to Wifi it’s slowed down to a crawl

im wondering if this is related to the release of big sur. some bug in connectivity that apple needs with their servers?

in the past ive noticed that if you wake up without working internet (but working wifi), it does the same thing.

yeah but this is really disturbing that apple having connectivity issues would disrupt normal system usage that is not apple related.

I agree, this is EXTREMELY disturbing that Apple has some sort of a connection to our personal Macs that can affect our entire Mac with their servers which means they have some hidden background processes communicating with their servers at all times.. How long do you guys think this is going to last?

This is a complete sh*t show from Apple.

I can’t use my computer because Apple had decided that it had to monitor every app I start.

And I need to join Zoom metings

This is happening on all of my Macs as well. Guessing it has to do with Gatekeeper, since macOS phones home every time you open a third-party app to make sure it's not malware. How has Apple screwed up this bad...

Yes, it's happening on our Macs, too. All are running Mojave. Apple apps open fairly normally, while third party apps are taking much longer than usual to launch, often timing out.

That seems to be consistent with suggestions that the problem is with trustd, Gatekeeper and other Apple "security" systems. Lots of trustd messages in the Console.app. Also noticing very high MRT activity.

My business' Macs are basically unusable right now. At least our Windows systems are working.

For me it affected much more than just app launches. Computer usage in general was very sluggish!

I tried disabling Gatekeeper from the command line, but that didn't help. Editing /etc/hosts as suggested in a prior post fixed it for me.

thank you for this! I just spent over an hour trying to get my Adobe apps to launch to no avail. Disconnected my ethernet and all went back to normal. So strange.

Hello, i have had multiple reports of this issue in the last 2 hours by clients running original macs. My hacks, wich have these services disabled by default, are safe.

I want to get something straight, Why does the entire system get slowed down to a crawl with wifi enabled? Does it mean that Apple literally has full access to our Macs and can view and control every single thing we do on our Macs at all times? i'm seriously trying to wrap my head around this situation as i think this exposed some serious privacy issue.. I never experienced such a thing happen on a Mac. I'm not updating to Big Sur nor do i plan on updating to Big Sur anytime soon, I am using Catalina on my 2017 MacbookPro 13 inch Model.

Oh man, I'm so glad this wsn't just affecting me. I booted up my MBP this evening and booting up Firefox was taking ages. Just clicking on the icon in the dock, it wouldn't even start bouncing for about 10 second, and then bounced for ages. I rebooted twice but still had the same problem. I then contacted live chat support and the support guy was telling me to install Big Sur, which I wasn't keen on doing. I politely declined and did one more reboot. All seems okay now, so perhaps Apple sorted it. I just don't understand though, why apps need some sort of online connection before opening. Even Microsoft Excel didn't work for me.

When apps launch they call Apple to see if they are safe / properly signed. So it’s hanging on that. Disabling WiFi means it doesn’t try.

does it do it still do it with gatekeeper disabled? what is that hosts file addressed that was mentioned in this thread earlier today? is it better to block that address or disabled gatekeeper via terminal altogether?
