I'm seeing 5 processes with network activity ( sending/receiving bytes ). I'm not sure whether these are normal occurrences?
List of processes
- apsd
- ntpd
- mDNSResponder
- trustd
- netbiosd
I researched a few of those and some were associated to file sharing via windows or bonjour, however I don't have any other PCs on my network to even begin sharing files with.
Best Answer
apsd
- Used for FaceTime push notificationsntpd
- Used to synchronize clockmDNSResponder
- Part of the Bonjour protocol, used to scan your network for other Bonjour-enabled devices (printers, computers, etc...)trustd
- Used for validating SSL certificatesnetbiosd
- Used when interacting with Microsoft shared drivesThis is all normal activity. However, if you are worried about security, you can disable the services you don't plan on using.
Edit: You might not want to disable
ntpd
andtrustd
as they are necessary for basic functionality such as browsing websites.
