macOS Catalina is rendering some computers unusable

Whenever a new operating system arrives, such as macOS Catalina, on our Macs, it generates a bit of confusion and sometimes fear. We can say that although the new versions are very stableIt depends a bit on how it is installed, the time and use of our computers and a pinch of luck factor.

Some users are reporting various issues with macOS Catalina. Most arise due to compatibility problems with the programs already installed, as for example with Photoshop. But also there are cases in which the new Operating System is leaving some Macs, as if they were paper treads.

macOS Catalina has had a good acceptance except for a few cases

In general, the installation of macOS Catalina is not causing installation problems on those computers that are eligible for the update. Nevertheless, there is the exception that proves the rule. Most of the problems that have arisen concern compatibility problems with third-party programs.

Recently new information has emerged, about some, few, users who after installing macOS Catalina, their Mac has stopped responding and is idle, without really knowing what to do.

Very few users have suffered this setback, but we believe that it is good to be known. It is said that the problem may lie in an EFI firmware update that was not installed successfully. Affected users state that all of them they see nothing but a folder icon when trying to start up their Mac.

Let's hope it's not you, one of those unfortunate users who have suffered this "disaster", which honestly looks bad. Not knowing at the moment what the real problem is, the solution cannot be determined. In case you are going through this bad drink, there is an open thread in the official Apple support, where you can share your impressions.

    I would like to know what the future would have of a program like Picasa that does not work with Catalina or what program is assimilated.
    I am very lay in these subjects and I have all my work in Picasa and if it disables it, it hurts me.
