A sizeable number of Mac users are experiencing occasional system crashes after updating to macOS Catalina version 10.15.4, released a few weeks ago.

The crashing issue appears to be most prominent when users attempt to make large file transfers. In a forum post, SoftRAID described the issue as a bug and said that it is working with Apple engineers on a fix for macOS 10.15.5, or a workaround.

SoftRAID said the issue extends to Apple-formatted disks:Other users on macOS 10.15.4 have experienced crashes after waking their Mac from sleep, with affected systems suffering a kernel panic and rebooting to the Apple logo, according to comments shared on the Apple Support Communities, MacRumors Forums, Reddit, and Twitter.

After updating to macOS 10.15.4, users may also experience continuous spinning up and spinning down of connected hard drives when a Mac is supposed to be asleep, which could result in damage to the drive, according to Jeremy Horwitz.

We've reached out to Apple for comment and we will provide an update if we hear back.

I've had issues with the browser taking a while to respond. Not a huge deal. Just annoying.

It’s happened to me once or twice.

Usually I wake to find the computer running very slowly with kernel_task taking up something like 300-800% CPU. The computer says it’s at 1% battery and will not charge when plugged in. Restarting does not help, you need to to truly shut down and then reboot and luckily that’s all that has been needed thus far to solve these panics.
Used to happen to me from time to time, it resolves if you unplug the power cable until the process terminates by itself. Then plug it again. But to be honest its been a while since the last time.
 
Its this stuff that makes me wish they would go back to the 1.5+ year OS cycle. I know they are stuck because they like to do them all at once - but the pressure to put features into each build causes issues. Imagine 1.5-2 years of rock solid Majave development and fixes, then come out with Catalina, and have time to perfect it.

Agree. I think users expect an annual update out of sheer habit but what they want is a well polished OS that doesn’t need five .x updates over the next year to “just work”.
 
Yesterday I did something I haven't done in 15 years of using macOS, having used every major release and patch release. I've downgraded my MBA '13 to Mojave. It became unusable with Catalina. The process sucks, I'm still reinstalling and configuring stuff but I guess it's worth it. Since 10.15.4 it couldn't even wakeup without crashing, last week I got a full system freeze when I was just editing a document and this weekend I had a kernel panic. SSD is fine, I've ran memtest for hours, there nothing wrong with this Macbook. I've been running 10.15 since it came out and it's by far the worst macOS release ever. Lion and Yosemite were heaven compared to Catalina.

After the lackluster iOS 13 experience, I believed the numerous reports on Catalina and didn't bother trying it. It doesnt have anything I care about anyway
 
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.
 
I’ve been having tons of Finder issues since the latest update. Anything with larger files seems to trip it up. It’s become so bad that last night I was running through diagnostics to be sure it wasn’t a hardware issue, but everything is coming up fine, and it seems to have been particularly bad since the latest update. And that’s just one more bullet to use when explaining that Catalina without a doubt has been the worst experience I’ve had with any Apple software.
 
We need a 2020 version of this.

Snow Leopard wasn't always perfect, though. It had a lot of issues during its .0-.4 (or even .5) version eras. Even 10.6.8 v1.1 had its own quirks.

It's easy to look back on SL as the coveted macOS that was flawless and just worked...but even beloved SL had its own issues, and in some ways, Mountain Lion was better than SL. More stable, faster, and had iCloud support to boot.

Lion, Mavericks, High Sierra, and Catalina would be the worst macOS versions for me.
 
I assumed waking from sleep at the Apple logo was a result of the VPN client or FileVault...good to know!

Happened to me this morning on MacBook Air 2019, in the middle of my shift at work. Also, I had pixelated screen when waking the computer up after being in stand by the whole night and had to hard reset the machine and then it just crashed at one point. Two restarts within an hour, abysmal.
 
Oh, so basically like any time you try to do a file transfer between drives on the iPad Pro? I've still never had that be stable. It's so bad that it has completely corrupted SD cards full of photos and I've had to reformat them on a Mac to get them to show up again. Fortunately I was using test data that I already had backups.

Glad to see that they're bringing the same great stability of iPadOS to macOS! /s
