A further update on my Catalina problems after sleep. Basically my native apps do not work after sleep until the Mac is rebooted..

I've had nearly 5 hrs worth of phone calls to Apple Support and submitted multiple screen shots and sys logs. There have been detailed investigations by the engineers behind the support staff.

By the way they strongly advise that anyone with problems should contact support and submit log files to them so they can eliminate the usual suspects of external influence or 3rd party software. They stated that they have very little evidence of similar problems to mine despite this and other blog files stating to the contrary. Without the full sys log info they state that they cannot identify the specific OSX problems and develop a solution...

After going through this exercise exhaustively with me they have now identified a problem in Catalina which is causing multiple errors to occur in the background eventually leading to core apps falling over. Don't know what the problem is but they are now working on a fix which will come in the next Catalina update.

Until then they advise that I should expect core Mac apps to fall over and cease to work after a period of inactivity whether the Mac actually sleeps or not. (which is the case). It is not related to the connection of external usb kit/ ext drives etc.

Until then I am advised to switch the Mac off after each use and also reboot before I do any word-processing etc to ensure native apps work ok and I do not lose work. However I have now also taken to using Libre office to get past the problems as this works and seems unaffected by the problem

I await a new Catalina update with bated breath

Hi GavinFoo,


Thanks for posting! I understand you might be having an issue with waking your MacBook Pro from sleep, and I'm glad to help.


To troubleshoot, I recommend starting with this resource: If your Mac doesn't sleep or wake when expected


"If your Mac doesn't wake when you expect

Your Mac might pause a few seconds before it wakes up. If it doesn't seem to wake at all, check for these possibilities:

  • Your screen brightness might be turned down.
  • If you're using an external display, your display might be turned off. 
  • Your Mac might be in safe sleep. To wake from safe sleep, press the power button.
  • Check for a sleep indicator light, if applicable, and make sure that your Mac isn't turned off."


If this doesn't seem to apply to what's happening, try these troubleshooting steps below. Safe mode and the test user account in particular may be helpful in narrowing down the issue:


"If the previous steps don't work

These additional steps may help identify or resolve the issue: 

  • Reset the SMC.
  • Reset NVRAM.
  • Disconnect external devices other than your Apple keyboard, mouse, and display. If that resolves the issue, gradually reconnect your devices, testing each time, until you find the device that is interfering with sleep. Then check the documentation that came with the device, or contact the device manufacturer.
  • Start up in Safe Mode to see if the issue is related to non-Apple startup items, login items, or kernel extensions. 
  • Try to isolate the issue by using another user account."


Cheers!

I have a brand new imac 27” with ssd and Catalina. Finder just stops responding after each sleep and spinning ball appears. I have tried all of the above several times and removed peripherals and start up programmes like Dashlane and it still happens. Driving me nuts £2k down with a c..p Apple update. Old mac mini with Mojave and ext ssd much better.

My late 2017 21” Mac is doing the same thing. I put it to sleep, and every time I return after an hour or so it has done an Emergency Reboot and wants to send an Error Report. I believe it may have something to do with detection of/external storage as sometimes on reboot it doesn’t detect all my external storage on Lightning 3 connections.

I just updated my late 2015 iMac to Catalina and now I'm facing this irritating problem; sometimes it freezes when I work on it and I can never wake it from sleep without having to emergency reboot it. COME ON Apple, this can't be true! You have to give us a solution now! Bad, bad work by the developers. I'm seriously considering a Windows computer as I feel like Apple are being more and more sloppy......

Note; Nothing was wrong before updating. Another irritating issue was that I couldn't use iPhoto anymore, I hate the layout and the way it's presented in Photo...

OK, This is absolutely crazy. We just as well start calling this CRASHALINA. Apple has released an OS update on the public that is bricking thousands of 2016 and older systems, and causing untold problems on newer Apple systems (like my iMac 18.2 2017 21" system). I tried the route of reseting my SMC. Needless to say that was a bust. Here's what I'm getting on the error report when I wake it up (after the emergency reboot):

It goes without saying, Catalina is a disaster - the only question now - Is Apple going to own up to it, fix or replace the equipment they break, and FIX CATALINA!!
