This fall is certainly not a walk in the park for Apple. The new operating systems still don't seem to be running completely stably. While iOS 13 has disabled some functions, macOS Catalina has rendered entire Mac devices unusable.

This autumn, the worm seems to be stuck deep in the apple. Of course, there can be bugs - but what users have to put up with under iOS 13 and Co. is no walk in the park. But let's come to the likeable and currently aggressive Catalina. The new Mac operating system seems to be in a bad mood at the moment. In various forums, including Apple's own, voices are being raised that macOS 10.15 Catalina has paralyzed entire Mac devices. These are unusable after installation. Affected devices remain completely frozen in the reboot process after installing Catalina. Even after several restarts, the affected device cannot be rescued from its predicament. The result is two scenarios. Either users see a folder with a question mark or they see nothing at all. The rescue attempt to access other drives using certain key combinations - during the boot process - is also completely ignored by the system. In other words, Catalina causes a technical KO on various Mac devices.

But why does Catalina react so dismissively?

There is currently speculation as to what triggers this serious bug. The answer could be corrupted EFI firmware. The Extensible Firmware Interface (EFI) was developed by Intel to replace the Open Firmware used on Power Macs. Apple itself has not yet commented on the problem. It is currently unclear how many users are affected by the bug. The fact is that reports of Macs being paralyzed are increasing and no pattern has yet been identified.
