And on April 6, 2020, an additional update for macOS Catalina 10.15.4 was released. However, even after adding an additional update, `` The 13-inch MacBook of 2018 model is broken and metamorphosed '' `` Mac system crashed after update, booted in recovery mode and restored from backup with Time Machine Yes 'was posted on the Apple official forum . In addition, many similar reports have been raised in the forum of MacRumors, a site mainly dealing with Apple-related information.
This additional update fixes FaceTime bugs, Office 365 bugs, and USB Type-C bugs, but it doesn't seem to fix system crashes that Apple hasn't announced as bugs. However, it has been found that a system crash is likely to occur when trying to transfer a large file, and that the drive may be damaged by the rotation speed of the HDD when recovering from sleep, SoftRAID , a RAID utility, says, 'We aim to share information with Apple engineers and fix it in macOS Catalina 10.15.5.'
