Keyboard and touchpad lost after sleep

The only question is, if something as fundamental as the Wi-Fi code in MacOS is corrupted, I think we shall see a significantly larger case number than what we have now. Even if this is an idiosyncratic issue to the 16", we should hear more people talking about this outside this forum. This really gets into my hair.

But another thing worth pointing is that this problem doesn’t happen with all WiFi networks. At least in my case. I guess there is some bug that in some cases, with some networks makes the keyboard not responding. I don’t know if it’s related to router or internet provider. I have changed my ASUS router lately to DECO mesh and still have this problem. I didn’t have it with some WiFis in one supermarket.

I think its one of the Catalina bugs. Because i didn't experienced this when I was using the previous OS. It started immediately I upgraded to Catalina. I think apple needs to fix this or we need a better OS version

my mbp Touch Bar 2019 model is facing the same issue after updating to macOS catalina 10.15.4. I found that this issue appears only when wifi is on and when I turn wifi off it wakes up without any issue i.e., Touch Bar/keyboard works fine. I contacted apple support customer care but they didn't solved my issue and seem unaware about this frustrating issue their customers face. Totally, unacceptable from this reputed company and such an expensive product. Even I told them that catalina is causing this issue as many customers are facing this and mentioning on apple communities discussion forum. Apple doesn't simply bother. in my opinion its a software bug, hardware seems ok. Hope apple is reading this and fix this asap.

Agree. The h/w builds are exceptional. For my family members, I usually have to get new ones only because they get so old that you can't get OS updates for them anymore and new apps won't run on the old OS. But that's typically 7-8 years, and they're still going strong. All the more reason this ongoing issue in new laptops is maddening. If it's still in the official .5 release I'm going to open a new case and just to stay on top of it. The squeaky wheel! Anyone who is under warranty or has AppleCare might want to do the same.

No, it is not something we are doing. I got a brand new MacBook Air last month and had the problem immediately. I had other issues and needed the bigger system, so I exchanged for a Pro 16". Also had the issue. I ran Catalina on my previous MacBook Pro 13" (2016) and did NOT have this problem. So, it seems to be a problem with Catalina and newer Macs; possibly the ones with the T2 security chip. But this is speculation from the user community. Apple has not officially acknowledged the issue though I did get a first-level tech to say they were aware of it - no details, though..

Yes, it happens with and without a VPN. I have (so far) noticed that I don't have the problem when keeping my Mac in clamshell mode with bluetooth keyboard, mouse and external monitors attached. So far, whether I use Wifi or my Thunderbolt Display's ethernet, I have no delay waking from sleep. Only when I'm opening the clamshell and trying to use the built-in keyboard and Trackpad.

ok - this is not happening now that I am back at work. However, it is happening often when I am at home. What setting on my modem and wifi is it?

This is definitely happening to me only at home. And only recently in the last 4 weeks.

I have two networks at home - both China unicom. One is a xiaomi and the other is a TP-Link thing... Happy to get rid of one of them if it means that this disappears.

Are other people using a specific brand of router? are they Chinese ones?

Interesting. It never happens at work, and you're always on Wifi (never ethernet?) What kinda of security settings are being used at home vs work? In each location, are you using 2.4 or 5GHz? To see the exact parameters of each, hold down Option key while clicking the Wifi icon in your menu bar - many of them will be shown there.

I just noticed that when I'm in my office, I'm only getting the 2.4GHz band because I'm a little too far for 5GHz. I don't have the problem here, but I'm also always in clamshell with external devices connected. I'll have to experiment and see if the difference is between signal bands or being in clamshell vs using the built in trackpad and keyboard.

when turn off wifi before send to sleep and wakes up it works most of the times, not always....other think that i found is bluetooth stop working, i got a message "bluetooth not available", need to restart...

i love my iphone, love my ipad, my watch, even my apple tv and mac mini... but hates this kind of things on my mbp...all problems related with energy managment, it seems pmset will help, but is useless, mpb not obbey pmset, like disable auto on when you open lid it....

Also having this issue. Started in the last few weeks. Running 10.15.4.

I'm using xcode and the ios simulator. Someone else said they were using VM ware, may have something to do with virtual sims.

Anyway, defintiley a bug. Hopefuly a fix is in soon.

Same issue. No keyboard or mouse detected after wake up. Has been happening for a few months even after updating. Reconnects on it’s own after an average of 2min 20sec. Please help Apple.

MacBook Pro (13-inch, 2018)

macOS Catalina 10.15.4

It doesn't seem to be a hardware issue, because we all have the same problem. When wifi is off, the bug is completely gone. Also, this didn't happen before Catalina. Yeah, I sometimes too get the "no keyboard or mouse detected" and it starts looking for a bluetooth device.

There's something very interesting I've noticed while trying to isolate the problem. Do any of you guys have bought something from the iTunes store? I bought one song a few years ago, and the other day I realized it is not available anymore. I couldn’t download it or listen it. I decided to erase it and reboot de Mac. The last 5 days this problem has improved a lot. I still get it, but it only freezes for about 2 seconds, almost unnoticeable. I wonder if this has something to do with login problems on iTunes or something related. You may want to try this too and see if anything gets better.

Through Feedback Assistant. I don't know if the recent update fixes this issue, as the workaround I posted earlier has been working perfectly for me in many days now, haven't seen any freezing at all.
