Catalina constantly crashing when Sleep

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.

Just to add another data point to this. I also experience nightly crashes on my 2017 27" iMac with Catalina (10.15.1).

I have sent a lot of crash logs to Apple. Hopefully it gets fixed in the coming OS update.

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...

I'm experiencing the exact same thing on my iMac Pro 2017. This is really ridiculous and infuriating. I swear, every since Steve Jobs passed the quality of Apple products has been in steady decline. I've been using Macs since 1988, and I can't ever remember a time when I regretted an update and really wished I could revert.

Ok, I have both an OWC 4-drive external Thunderbolt 2 and a 2-drive Thunderbolt 2 enclosure. Both are full with 2 Tb 7200 rpm hard drives. I have never had a problem with them until I installed Catalina. But my big question is - how can they be drawing to much power when they both have their own power chords with in-line bricks? They are not drawing any power from the system, just data.

YES! This is a wonderful question you ask. It makes no sense this is why I looked it up today. Something is not quite right. I'm going to call tomorrow and see what they have to say. I will report back!

Sure, but it’s stopped my iMac crashing while I’m trying to work remotely so it’s definitely better than nothing.

I’d still appreciate if Apple could release usable software that doesn’t require workarounds but that’s not the situation right now...

Experiencing a similar issue. 2015 Macbook Pro. Upgraded to Catalina.

Anytime I try to click the "File" menu in iMovie, it crashes the entire machine. Tried first aid on the drive, tried updating. Also getting random reboots when I try to select the little apple icon in the upper-left of the operating system.

What a mess...

My only suggestion for those posting here is to send Apple lots of crash reports.

An update on my problems. The iMac is a brand new 2019 one and this is a fresh Catalina install with files and settings migrated over from a Mac mini running Mojave.

After the iMac is awoken after an overnight sleep the embedded apps (Preview, Pages, Numbers etc) will not open stored files. The native apps appear to work if you start a new file but you cannot save them. Other non Apple apps work ok with the same files

I have spent over 3 hours on the phone with different Apple Agents. The problem has been isolated as only happening with my profile. Safe mode and a vanilla test environment are ok. We're still battling through the various processes though to see if we can flush out the issue. No luck so far though. An engineer's review is now booked and hope they can find a way forward. I will post the solution if it is obvious in due course

Is there any fix in sight for this? Almost every single day since I installed Catalina (about a month ago), when I switch on my new 27 iMac, I find out that it has crashed with error reports much like those mentioned above. Can this seriously be going on since Oct 11, when this was posted, and there is still no fix?! Needless to say that none of the recommended solutions mentioned as a response to the initial post by GavinFoo work.

This is really a shame...

Bought a 16 inch mac book pro, spent lot of money and a so basic function is not working properly.

I mean, Apple is on of the richest companies in the world but cannot test their products properly?????

I hope this is going to be fixed soon, it ruins completely the good old feeling of using a mac...

This happens every time my MACBook Pro goes to sleep with no attached storage or anything else on my MACBook PRO, just the motherboard and SSD which are built in.

I got into apple because Microsoft was so bad with new releases. Now Apple seems to have swapped places, perhaps it's time to move back to Microsoft which seems to be better than Apple at its releases.

Is there ever going to be a fix?

I've also isolated mine to an OWC Thunderbat external RAID drive. I unmounted the drive and the sleeping waking problem went away, but the drive will not auto mount now. I've contacted OWC technical support to see if they have any update RAID software, but I'm a bit confused by Tony's post. Does my computer need those components to run RAID, or is it some Apple stuff that I don't really need that interferes with my RAID software for the OWC hardware? I other words, if I remove the files he describes, will my OWC RAID device start working again AND the waking up problem will go away?

Thanks a bunch!

an update on my own post:

I am sorry, the new cable did not solve the problem, but gave me another error message:

"BAD MAGIC! (flag set in iBoot panic header), no macOS panic log available"

I agree.. this is BAD...

the difference was, my macbook did not crashed while getting into sleep and even 20 minutes of after that.

That was last night. This morning I found out that my macbook was shut down and had to be boot up with power button, giving me above BAD massage.

I tried new profile, safe mode as well as NVRAM and SMC reset.

All didn't work.

Talking to apple support makes me more frustrating....!!!!

Sorry for the "!" s...
