Just installed macOS Catalina 10.15.7 Supplemental Update and now any app that is not native like safari, calendar and etc is taking a lot of time to open.

Cannot open new apps Recently upgraded from 10.13 to 10.15 (Catalina). However it will not let me open any newly installed apps. All they do is crash. Older apps that ported over when I upgraded do open, it's the apps that are freshly installed that do not open. The installation of these newly installed apps seems to all be OK, other than they do not open. I did install TechTool Pro 12 to diagnose the issue, but ironically since it's newly installed it also will not open. How do I troubleshoot what is causing these newly installed apps not to work?

App Store not opening after the latest Catalina update on MacBook pro Hi, I just updated my 2012 MacBook Pro to the latest version of Catalina and the App Store won’t open. It just gives the loading beach ball and won’t open when I look at the app in the task bar it shows application not responding. .it was working fine before the update. I have tried everything and nothing works. I have tried to change the date, restart the app and restart the computer. Does anyone know how I can get the App Store working again?

Hi b0telh0,

It seems you're having trouble since updating macOS and we can help.

Try starting to safe mode to see if the behavior continues:
