Hi,while analysing some error messges on MacOS via Console app, (about errors from the Messages.app), I found that Messages.app is trying to look for PersonaUI.framework at some system directory, but it does not reside anymore where Messages is looking for it, because it has been moved to other system directory.Target: MacOS Messages.appLogged on Console: [type: FAULT] (red bullet)_______/System/Applications/Messages.app/Contents/MacOS/Messages (/System/Library/PrivateFrameworks/ContactsUICore.framework/Versions/A/ContactsUICore) Messages (ContactUICore) Subsystem: -- Category: -- Activity ID: 0 Thread ID: 0x2e1d6 PID: 25361 Failed to Soft Link: /System/Library/Frameworks/PersonaUI.framework/PersonaUI (2)_______So I decided to check if the respective framework does exist or not.But it does not exist under:/System/Library/Frameworks/ContactsUICore.framework (according to the error, it is where Messages is expecting it to be)Instead, it does exists on the operating system, at another place:/System/Library/PrivateFrameworks/ContactsUICore.framework----I could softlink it from PrivateFrameworks, to Frameworks, but the new system is read-only..so there is no solution, unless Apple fix it.This is just a eport about this situation, which happens on Catalina 10.15.4 Beta (19E224g)
