Good evening everyone, I write in this forum for an error message that the compiler from terminal MacOS returns me after sending the command: language gcc program.c Specifically, the terminal returns me this message: language objc[4135]: Class AMSupportURLConnectionDelegate is implemented in both ?? (0x1fb10c188) and ?? (0x118aac2b8). One of the two will be used. Which one is undefined. objc[4135]: Class AMSupportURLSession is implemented in both ?? (0x1fb10c1d8) and ?? (0x118aac308). One of the two will be used. Which one is undefined. I don't understand what it means or how to solve this message that appears every time I compile a program for the first time after turning on the Mac. I should point out that this problem has occurred on a Mac mini with an M1 processor. My MacBook Pro 13" with Intel processor does not have this problem. The compiler compiles the program perfectly but the error always appears. Is there any way to make it disappear?

Good morning everyone. I am writing to figure out how to solve a problem I am having with my Mac mini M1. I own a new Mac mini with M1 processor and a 13" MacBook Pro with Intel processor. I wanted to configure both so that at any time I can connect remotely via VNC. I configured the two Macs this way in the system preferences: When I connect from my Mac mini M1 to my MacBook Pro Intel there are no problems in fact everything works perfectly. However, when I connect from my MacBook Pro to my Mac mini I get this error: I can't really understand what the problem is also because looking in the Firewall settings I see that the remote control is enabled for incoming connections. These are the configuration screens of the integrated Firewall of the Mac mini (identical settings in the MacBook Pro): If I completely disable the Firewall on my Mac mini then the problem is solved but I would like to keep it active so as to add an extra layer of protection. How can I solve the problem? In the Firewall settings everything seems to be ok and they are perfectly equal to those of the MacBook Pro. It should give me the problem there too if it was a configuration problem but instead it doesn't. Could someone help me solve this problem? Thank you in advance.

Hi there! I am asking for help with an issue I am experiencing on my Apple calendar. I used to see all the annual Italian holidays but unfortunately from 2022 I don't see any event that I could see in 2021 instead. I attach a screenshot. The calendar is perfectly configured and enabled but I don't understand what the problem is. The problem is also present on other Apple IDs of my family members all with the same problem. Is it possible to solve it in any way?
