MacBook Pro Mouse and Keyboard freeze after opening the Lid

Question

So recently my MacBook Pro 2018 Touchbar (4 USB-C and Intel I5 Quadcore) has been having a really weird problem after waking up from Sleep. Every time I open the Lid and log in, the screen wakes up like normal and sometimes I can see new notifications from Firefox.

However, my Mouse and Keyboard stay completely unresponsive.

I see the mouse cursor, but it just won't move. CTRL + Arrow key also won't change screens. It's exactly as in this post here from 7 years ago and sadly no fix.

• It occurs from only for a few seconds to up to 30 seconds sometimes.
• It also happens always for at least a few seconds, no matter where I am or what state I closed the lid in.

What could remove or resolve these post sleep freezes?

Answer 1

UPDATE: The NVRAM reset ended up being only a temporary fix. The answer here was the real solution. The problem seems to either be with VM software or closing the lid with a VPN running (the latter was the problem for me). Disconnecting from the VPN before closing the lid fixed the problem.

Original post:

This is a bit late, but resetting the NVRAM seemed to work for me:

1. Restart your laptop
2. When the Apple logo comes on screen, press and hold option + command + P + R
3. The logo should go away and come back after a few seconds, and hopefully that should be it!

Answer 2

In my case this was happening even without a VPN or VM in use, so the link above might not be relevant for everyone. After seeing some claims that this issue was related to the SMC, I found this page:

https://support.apple.com/en-us/HT201295

Following just the first hard-reset steps in that link worked for me:

1. Shut down your Mac.
2. Press and hold the power button for 10 seconds, then release the button.
3. Wait a few seconds, then press the power button to turn on your Mac.

And I haven't had any issues since then (a couple months), with or without VPN.
