Catalina Breaks all apps

Catalina beware! After upgrading to Catalina, almost all of the apps that I was using daily no longer work. Over 50% of my purchased apps are NOT COMPATIBLE with Catalina. What a horror show. DO NOT install unless you are willing to lose all of your apps! Apple should have issued a BOLD warning to not install unless you understand that none of your apps will work. Additionally, you can' even find replacement apps to buy, as nothing is compatible with Catalina. How do I downgrade myOS?

Once you upgrade, you can't downgrade the OS. Insane that even programs like Adobe Acrobat don't work anymore. Nice upgrade Apple!

Why is it Apple's fault if third party app developers abandoned their old apps and refuse to upgrade them to 64 bit? Apple users were provided repeated warnings about upgrading if they were using 32 bit apps and yet you still upgraded to a 64 bit only operating system.


You can restore to your previous operating system from your backup.

From your reply, one might think that you know what you are talking about. However, have you ever downgraded from Catalina from a backup? I went to the Genius Bar and found that it can't be done that way. If you have done this, share your great wisdom.

Apple seems to think it's possible:

Same thing happened to me and when I went to Apple for help the person ERASED ALL MY QUICKEN DATA!!!

If you didn't have a backup in some manner of such important data,

it was an accident waiting to happen as anything can go wrong OS

update or not. Trusting your digital life to a single device is dangerous

especially as cheap as backup options are these days.
