I have been on Catalina for almost a week and the experience has been nothing short of a disaster. I am using a Macbook Pro 2012 with 8GB RAM and a 2.9 i7 chip. It was running smoothly with Catalina’s predecessor: Mojave.
However, since I upgraded to Catalina, not only is my computer running more slowly, but I also have issues with a variety of apps. Even though I paid for my CleanMyMac, here is it asking me to upgrade because of Catalina

I am supposed to work remotely today and it requires using a VPN, which in my case is Citrix. Here is what my colleague in IT department told me this morning

My Snagit keeps freezing and crashing, prompting me to download another screenshot application.
Here is what my friend sent me this morning as well

I can’t remember the last time I was this upset with a Mac OS update. I hope that Apple will pull it together and release a new version that fixes all the issues
