Some Users Experiencing System Crashes on macOS 10.15.4, Especially During Large File Transfers

I am also seeing Safari 13.1 (in High Sierra on one of my Macs) no longer trusting web sites and constantly reloading them. It has rendered Safari almost useless
 
So that’s what it was?! I thought my Mac mini had a problem. I was wondering why my Mac mini kept crashing especially when I was doing large file transfers! Even my Mac crashed at extensive tasks, cuz I was booting off an external SSD.

It's been said one way , many times for the last 40 years : for production ready Systems , keep to the last shipping Build version of the previous OS version .

Using a state of the art OS for serious work is always risky .

Agreed. But how can anyone anticipate that an operation as fundamental as "copying" a file will be broken? It's not like some new cutting-edge experimental feature.

Honest question, I’m on macOS 10.15.3 and I was about to update to macOS 10.15.4 along with iOS 13.4

Should I wait on macOS 10.15.3 until 10.15.5 is released? Thank you

Not the only problem I've been personally having after updating to 10.15.4. My external monitor stopped connecting right after the installation, and had to do an SMC reset to fix it. It still doesn't always connect.

I've also been having this issue that my cursor/keyboard sometimes remain unresponsive for several seconds after waking up from sleep.

Edit: all of these sporting the supposedly latest and greatest 16” MBP

Yes, I'm having clamshell mode issues now, and the beast is rebooting at night.

I've been somewhat forced to deal with Catalina because I upgraded to the 16" Pro and so far I am just sad. macOS is an incredible piece of software and it's upsetting to see Apple's B team handling it. This article is not a surprise to me at all. The entire OS is death by a 1000 cuts and for what many rely on for their livelihood I hope Craig and the team consider a Snow Leopard type release this year. We're on .4 and so much stuff is still broken it's depressing.

I had this problems also on my MBP15 2018 - deactivating power nab helped to get rid of the crashes during sleep ☺️

Still on Mojave. Longest I've ever waited to upgrade the OS. Will probably just skip Catalina altogether.

I've waited a full annual upgrade cycle for the past 2 releases (Catalina will be the 3rd). It used to be (service pack) "3 is the magic number" but I've noticed that what they do now is add new features (and bugs) through the .4 release. Then they stop adding new features to the subsequent .5 and .6 updates which are dedicated to squashing as many remaining bugs as possible before abandoning that release for the next.

This has served me well. All things being relative, I'm still on an annual upgrade cycle; just perpetually one year behind but the trade/payoff is the least amount of bugs, crashes, issues, data loss...

Yawwwn. So this finally gets coverage. It's been happening since 10.15.0: https://discussions.apple.com/thread/250717203

Apple has been in touch with a number of reporters (myself included) and it seems they haven't been able to find the root cause behind these kernel panics. TL;DR: Happening to those with external displays; sleeping causes mac to crash. Also those with external USB drives / devices most likely to panic. The only way is to prevent the mac from sleeping (there are tools out there that do this). I've had this going on since 10.15.0. My new MBP Pro 16" crashes all the same (with external monitors) but ever since I installed an app that prevents the Mac from going idle, it hasn't crashed once.

I've had a similar issue with an external monitor. Maybe 1 in 20 times the Mac KPs, but other times it will not connect to an external monitor until it's rebooted.

I just received the new MacBook Air which comes with Catalina and transferred all my data from my previous one that was running Mojave. What a nightmare - it took four tries, and I lost countless hours to clean out 32bit software. Worst of all is Mail though, where it was dumbed down so that it is no longer possible to resize or rearrange columns. I was right to hold off 10.15 for as long as I could...

One has to be a glouton for punishment to voluntarily upgrade to Catalina OS.

NOTE:
Mojave is not faultless, either.​
On a lower scale of nuisance (if you are not hearing impaired), Safari ignores Closed Captioning on all embedded video (it does not ignore automated Closed Captioning from youtube video). It has forced me to use Firefox, which displays all Closed Captioning that Safari simply ignores, but triggers, consistently, Diagnostic Reports caused by WebKit Resource Wakeups.​

So during this Quarantine time I decided to to try and access an external hard drive that had 150GB of Photos and 200GB of music on iTunes. But sadly the hard drive kept reporting errors and was gonna fail soon. So having updated to the newest Catalina OS, I tried to transfer and every single time my MBP would show the spinning beach ball and then would crash horribly. This update has been freakin awful with the process!

This is what's killing me. We're already on .4 around the time when things typically have started to stabilize with these releases, but .4 has been the worst yet for me. I'm planning on creating a new Partition for Mojave to use when I actually need to get work done or want Logic Pro X to not constantly beachball which has also been happening since the new update, though I assume it's somewhat related to working with larger file sizes.

Sooner or later, hopefully sooner, Apple may see a drop in sales due to this Catalina mess getting publicity, and do something about it.
I've been watching these forums long enough to never having a thought about touching Catalina.
Lots of naysayers will say why not upgrade, and move along with progress.
Well, have fun you guys, sweating with your fixes.
Mojave does all I really need smoothly and safely, and I don't have to waste time and effort coping with Apple's failed QC, and the neat Catalina "new things".
My huge iTunes and Photo libraries are safe and everything works just fine.
The forums will tell me when it might be safe to upgrade.
36 years with Apple have taught patience and skepticism since Jobs' ideas and quality went away.
