Saberon2014, who got such a Mac mini with M2 Pro, reports a problem with the Ethernet port on a forum operated by Apple-related media MacRumors .
Mr. Saberon2014, who got the M2 Pro-equipped Mac mini that was released in the United States earlier than Japan, said on January 26, 2023, 'Today, I got the M2 Pro-equipped Mac mini, but it's messed up. So when I do a Ping command to any site like google, I see 50-60% packet loss , wifi is fine, even though I have another pc connected to the same lan cable I tried it at my friend's house and it was fine, but I saw the same problem,' and reported that when the Mac mini was connected to the internet using a wired connection using a LAN cable, there was a communication problem. bottom.
Saberon2014 seems to have reinstalled macOS, but it seems that the problem has not been solved. Also, multiple Mac mini users with M2 Pro have reported similar problems, but some people have reported that 'the packet loss in my environment was about 15%', and the packet loss percentage seems to be quite mixed. Also, Mac mini users with M2 Pro in Italy report no packet loss issues.
When Mr. Saberon2014 contacted Apple, it seems that he was offered 'I will exchange it because it is a defective product', and even among users who share opinions on the forum, what is the problem and a large amount of packet loss is occurring after all? remained unclear.
However, a user changed the Ethernet setting from 'settings' → 'network' → 'ethernet interface' → 'details' → 'hardware' to 'manual' and changed the setting 'Configure' to 'manual'. After turning off the 'ABV/EAP' mode in the settings, they report that the packet loss has stopped. Therefore, it has been pointed out that the packet loss problem of Mac mini with M2 Pro is a software problem, not a hardware problem.
Also, some users who were already using Macs reported that they were able to avoid packet loss issues by restoring from a backup.
In addition, it was reported that the Mac mini with M2 Pro that had the packet loss problem had macOS Ventura 13.0 to 13.2 installed, and when macOS Ventura 13.2.1 was delivered on February 13, 2023, ' The packet loss problem has been resolved.'

However, a user on another forum said, ``After installing macOS 13.2.1, the symptoms were improved, although the problem was not completely fixed. I was able to improve it by about 10% with the OS update,' and some pointed out that the OS update did not completely eliminate packet loss.
