macOS Sierra keeps freezing

I've noticed an on-going issue around external USB devices. Keystrokes will get lost (and I don't type that fast). Some drives don't get "seen" by the system so they have to be power cycled or unplugged from the USB chain and then plugged back in.

Not exclusive to Sierra since it was in the previous version too.

It's as if polling of the USB/USB Cache isn't properly implemented.

same here ... you should uncheck this as answered ... mine happens on RMBP 2012 . I loose all functionality (seems like a kernel panic) The majority of the time it happens with safari opened .

Exact same issue here on a 2015 13" MBP and 2012 15" MBP. It's working fine without displays connected. Connecting external displays, including an Apple Thunderbolt Display, cause the whole system to freeze exactly as described.

This behaviour is both on stable as well as PB versions of MacOS.

My rMBP 13" 2012 has been hanging and freezing since upgrading to MacOS Sierra, too! It does seem like a kernel panic - similar to when I upgraded to Mavericks few years back. I had to hard-restart it for god knows how many times in a span of 2 weeks.

How can I downgrade to El Capitan? EC was a lot more stable for me, I never had to deal with this problem with EC.

Thanks!

Same here. MacBook Pro (Retina, 15-inch, Mid 2015). Connected to an external monitor and a USB Hub.

Has been working fine with El Capitan with this setup since purchase.

Since Sierra install, I get about 1-2 freezes per day, exactly like described above.

Yup exact same freeze happening here, external USB keyboard and wireless mouse stops working, then a few seconds afterward, the laptop keyboard and trackpad also stops. There is still activity on the screen (as indicated by Little Snitch Apple Menu widget) but the keypads and mouse do not respond.

Hard restart is the only fix so far but happens intermittently throughout the day.

• MacBook Pro (Retina, 15-inch, Mid 2014)
• 2x external monitors (thunderbolt and HDMI connected)
• USB Apple extended keyboard
• USB Logitech VX Nano Mouse

It happened again - Yesterday and Today. I keep hard-resetting my rMBP, because the video would freeze and the audio would leave a 'bzzzz' sound. I'd really like to downgrade to El Capitan. This is getting frustrating.

I have followed advise on one of the forums and ran EtreCheck... would love it if some of you who are more techncial talented could provide feedback and guidance for me please... the spinning ball and response times are driving me around the bend

Thanks...

Same here, this is where I'm at with support :

Safe Mode:

1. Shut down your Mac and wait 10 seconds.

2. Press the power button.

3. Immediately after you hear the startup tone, hold down the Shift key.

You should press the Shift key as soon as possible after you hear the startup tone, but not before.

4. Release the Shift key when you see the gray Apple logo

To leave safe mode, restart your Mac normally without holding down any keys during startup.

SMS Reset”

1 Shut down the Mac.

2 Plug in the MagSafe or USB-C power adapter to a power source and to your Mac.

3 Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time.

4 Release all keys, then press the power button again to turn on your Mac

To start your computer from Recovery, restart your Mac and hold down the Command and R keys at startup.

Hold these keys until the Apple logo appears. After your computer finishes starting up, you should see a desktop with an OS X menu bar and an OS X Utilities window with the options listed above. If you see a login window or your own desktop instead of the Utilities window, it's possible that you didn't press Command-R early enough. Restart your computer and try again.

Would this hold true for Logitech Gaming Software? I don't have the LCC software but do have the LGS for controlling features in my G303 mouse. I deny it access to controlling the OS though.

Just did a search and they don't have anything newer than v8.83.55 for macOS v10.8.x through v10.11.x (August 3/2016 release).

I went ahead and updated it since mine was 8.58.40. Odd that, out of all the other stuff, they don't have an auto check for updates.

As I said before I have both a MBP 13" and as well as a MBP 15". The latter is with LCC 9.3.5 (latest release), the first without. Both had the exact same problem on several external displays. Removing LCC did not change that for me unfortunately. However, I did have some success with macOS 10.12.1 PB3. Since installing it on the 15" I haven't had a single freeze. The 13" MBP without LCC and macOS 10.12 just froze on me again a couple of hours ago, so I decided to also update it to 10.12.1.

Please be advised that beta's should not be used on production machines. I am not in any way suggesting you should update to the public beta to get rid of the problem, just indicating that 10.12.1 might actually solve the problem.

I updated LCC and haven't had a crash in a few days. Looks like that's the solution. Thanks

I had the same problem on my late 2009 iMac. I tried everything. EVERYTHING.

• Reset SMC
• Run Etrecheck and clean up all the old "junk"
• Reinstall Sierra three times
• Boot in safe mode
• Delete Finder plist files

It came to the point that Finder was crashing every time my Mac woke up after sleep. The only thing that solved the problem was to do a full system restore from Time Machine back to El Capitan.
