Users Facing System Crashes on macOS 10.15.4

After a major software update, devices are bound to see some bugs and performance drops. However, even after a relatively minor operating system that was rolled out a few days ago, some Macs running macOS Catalina 10.15.4 are facing system crashes.

Some users have started complaining about system crashes ever since the macOS 10.15.4 update was released a few weeks ago. The issue seems to be most noticeable when users are trying to transfer large files. Users have been talking about this issue on several forums and on social media.

SoftRAID, a tool that helps users in monitoring and testing disks, said in a forum post that system crashes during large-sized file transfers is due to a bug. The forum post mentioned that the issue extends to Apple-formatted disks. The company said that it is working with Apple engineers to find a workaround and a permanent fix for the software bug.

It is being reported that systems are crashing when a lot of IO threads are being used. SoftRAID volumes appear to have taken the highest hit and it is now apparently impossible to copy more than 30GB of data in one go. Users have been noticing system crashes while waking up Macs from sleep after kernel panic and subsequent reboots.

There’s no solution to the problem as of now, but Apple could issue a minor software update to fix the problem. Some users are claiming that their Macs running macOS 10.15.4 are crashing when connected to external displays. Macs running Windows via Bootcamp appear to be running better than Macs running macOS 10.15.4 as of now.

My MacBook Pro 16” has been experiencing random restarts due to a kernel panic since I updated macOS to 10.15.4. Is anyone else having similar issues?! 😩 @AppleSupport

My MBP upgraded to 10.15.4 and has been crashing with kernel panic every time it goes sleep since then. Insane.
