This has been happening. One of my apfs external drives got messed up. It wouldn't mount but could see it in Disk Utility but would fail getting First Aid. I had to buy a new drive & recovery software to save my data. Could this bug have caused the APFS object map error & make the drive not mount or be usable?
You weren't backing up this important data because...?
 
That’s a really good idea. You get a nice feature feeeze and only security updates. So nothing should go nutty.

Catalina ok for me. 2 kernel panics over 3 months which isn’t the worst thing in the world but it way up from my previous 0.

I might just downgrade to Mojave so I can be same boat as you!



I’ve gone from immediately installing all updates in the 10.0 to 10.2 era, to waiting for the first point release, then the second or third point release, to waiting a few months, and finally with Mojave not installing it until after Catalina was released. (Later than my comfort level was fine with it but I’d gotten lazy and apathetic. A month or two before Catalina would’ve been Ok.)

Decisions based on feedback from everyone here, thank you very much. Consequently I’ve had very little post upgrade regret.
 
Got my MacBook Pro on Friday and immediately had this issue waking from sleep with lid closed. Just got off a call where I was offered to escalate it to engineering or swap my machine. I’m afraid any swap would have the same issue and it’s such a great machine in every other aspect I went the engineering route. Still 10 days or so to decide if I am going to keep it...

I had the exact same experience with a 16” MBP that arrived last Wednesday. Every time I opened the lid, it had crashed and needed to restart. Apple said they had not heard of the problem before and recommended that I send it in for service. I decided to swap for a new machine since I was still in the return window. Now that I’m seeing these reports of it being due to Catalina, I wish I had just kept it while (impatiently) waiting for a software fix...
 
I had this issue, on a corporate MBP 2019 13" which has enforced sleep settings (10 mins), so if I was away from my desk longer it would sleep and not resume - also seeing sporadic panics during use.

However, in my case, disconnecting my Lacie TB external disc seems to have resolved it.

With it connected, sleep/resume will fail 100% of times, disconnected it seems fine and have been working for 4 hours with no random panics (had 4 in the first 3hrs today).
 
Makes you wonder about Apple's QA processes -- something like this is so blatantly obvious, are they incompetent or just lazy -- or obsessed with turning out volume (quantity vs. quality). With these and the other bugs (iOS), Jobs is likely rolling in his grave (RIP), he would tear them all a new one (and rightfully so).

I have been to many places where Agile is used and the stuff is not properly tested. Agile may not be the problem directly, but it is definitely the problem if you know what I mean. Just like you said. And every single business is now using Agile which is pretty irritating as I have been with several that are not testing their stuff properly because they have to get it out in 2 weeks!
I have been to many places where non-Agile methodologies are used (in some industries Agile is not the main methodology... yet) and the stuff is not properly tested either: especially when the methodology assumes e.g. a dedicated testing period, development (invariably...) overshoots the estimates and the testing period gets sacrificed instead of delaying the whole project.

Getting stuff out in 2 weeks... in a truly Agile setting if you need more quality you release more frequently, not less. This is actually how I gauge whether a team is really Agile or just going through the motions: if they want to release more frequently when things get hard they are Agile, if they want to release less frequently, they are not. In the most Agile team I worked we had weekly release cycles and when things got hard we'd switch to daily releases. We had hundred thousands of automated regression tests though.

This is the underlying reason why many teams who want to do Agile don't actually reap the full benefits from it: Agile is often taken as some holy grail which automatically solves problems but the key of the methodology is being able to split complex problems in very small pieces and it's actually very hard to do without the correct mentality, experience, discipline and working conditions.
 
soon apple will release a statement

this is why apple still includes 5400 rpm hard drives with their imacs in 2020 to avoid this kind of problem, is your fault for using ssd and m2 drives

😂

When is your new machine expected to arrive? I'm really interested in seeing if you have the same issue... B&H is having a sale, I could get a new machine for about $20 more than I paid for my refurb.. but other than this issue (which is livable as long as it doesn't get worse) I really love this thing and don't want to be without it while I send it back... lol. I have until the 16th to decide on mine.
 
Yeah, what I’ve found is, if I step away from the desk long enough for the MBP16 to sleep, when I come back, the cursor & performance will be laggy, fans will be cranking like mad, drives won’t eject, and it’ll eventually hang & crash when you inevitably reboot. When it does reboot, I notice some graphical sputtering and gagging getting back to the desktop. This is still an unstable boot, and the same problems will be present. So I reboot again right away, and then it works like it should.

I turned off power-nap yesterday afternoon and thought that might have fixed it, but it’s hard to tell since Keyshot crashed it twice on its own since then. I joke that all my reboots since buying this computer are actually hangs and crashes, while the old 2009 MBP17 acts like a server and CNC machine control 24/7 and hasn’t been rebooted once since Sierra went on it.

I looked into people’s attempts to put Mojave on the MBP16, and of course the sticking point is the missing graphics driver. Apple could cure a lot of woes by doing something unusual for everyone who spent a fortune on these MBP’s and needs a stable release, by issuing a late update to Mojave with the graphics drivers we need so we can upgrade to (or past) Catalina when it’s mature instead. But obviously that’s as unlikely as it is.

This is an additional issue that has plagued the OS since the introduction of power nap, it seems to kill the discrete graphics card when a message or email come in, and the machine wakes briefly to display the alert. When you then take it out of sleep the graphics will be messed up real bad.
 
Audio cutting out for me when I quit Spotify and open Music and vice versa. Have to restart to fix it.

And that is the problem. Every business I apply for is Agile on paper, but they sometimes do not release every two weeks. I have been to a place where they release something in 2 weeks regardless if it is properly tested or not. This is where the issue lies. Wait until its properly tested. Not all code is equal. Some stuff requires more than 2 weeks of development time and others don't. However, some places make you rush it out the door.
 
My external drive that has my data and time machine backups was corrupted post .4 upgrade.

Lesson for me to disconnect all accessories when I do an os upgrade.
 
I’m waiting for the return/refund to be processed before I order the new one. Hopefully I’ll have it early next week

Turning off the power nap features in the energy saver settings has worked for me so far... had about 3 instances in the past 24 hours that previously would have caused a restart and did not this time. Have to see if it lasts..
 
We need a 2020 version of this.

Man, I remember when Leopard came out, and all the rich features they packed into it, it was so good. Then they bring out Snow Leopard, and work on solid optimization of the OS - couldn't believe it.

I have to say, Snow Leopard, and Mojave are my top picks to date. Mojave wasn't perfect, but it definitely stood out in the last few years as being the best OSX experiences I've had in 15 years of Mac usage.

I did my customary Combo Updater (instead of the Delta Updater) to X.15.4 and it crashes all the time trying to come out of Sleep on my 2019 16" MacBook Pro 32GB / 2TB. Usually it is fine as long as the 'Screen Saver' is still sliding my 'Dad's Favorites' photos around the screen...but if the screen goes dark...then it's done for, for sure. It actually might be crashing more than what I've observed...as it has almost always when when I come back from doing something (sometimes not long).

I am in the exact same boat! They escalated to Engineering and everything. My rep was Loren, I’m not sure about you, but she’s been great and it’s been a mess though. She told me not to return it yet. She said I should wait until after it’s fixed with a software update and then just return it then. She said that the return policy is super chill right now with them having no stores open.
 
I've been having issues while copying large directories from my old laptop to the 16" I just received. I wanted to started fresh, so no time machine backup but I decided to copy only some directories. I'm not done yet, I have to do it in small chunks. Both laptops are running 10.15.4

If they fixed it why would you return it? I’d also be very weary of the return policy. I was told I had 14 days, adding time due to the stores closing was for purchases between a certain window (I think like Feb 20-March 14). My purchase is a straight 14 day policy I’m told...

You are both talking about the 16" model? I'm assuming so, just curious.
 
10.15.4 supplemental update 1 didn't seem to fix the kernel panic while sleeping issue on the 16" MacBook Pro - it's unreal that my $3000 laptop can't even go to sleep and wake up reliably 👍

Do you have power nap setting on? Turning that off fixed this issue for me.
