MacOS Catalina 10.15.4 fails with big data transfer, according to some users

MacOS 10.15.4 is the latest active version of Apple computers. Some stories we find in this version the ability to share iCloud Drive folders from Finder, new Playtime feature restrictions, music videos synced to Apple Music, or Netflix playback HDR content on compatible devices.

This version of Apple's computer operating system is already available for a few days, so most users install it on their computers. Several people are reporting an annoying failure of this old update for devices to disappear, forcing them to restart to continue using.

There are also problems after hibernation

Users who have experienced the problem say that the failure occurred while trying to transfer large amounts of data, but it seems to be the case others are also affected by taking over their computers without restraint, sparking panic and causing the computer to restart, according to Reddit testimonials and Apple support forums.

There is a major problem with macOS 10.15.4

It happens with a variety of settings, including Apple discs, though it is most possible when there are multiple IO cables. We think it's a thread problem. Although SoftRAID volumes are the most affected (it's hard to copy more than 30 GB of data at the moment), all systems are affected.

In our bug report we sent to Apple, we used a method that reproduces the problem with just ASED Apple discs. It takes a long time to reproduce, but there is plenty of opportunity for the production of a user solution. – SoftRAID forums

Another problem that may arise after the update is that the connectors connected to the hard drive work when the mac has to sleep, which can damage discs, according to Jeremy Horwitz.

Users who have not updated to the latest version of the MacOS Catalina 10.15.4 program are recommended. don't do it until Apple releases the pool which solves the problem.
