No Network access: NSPOSIXErrorDomain:1

I can't do anything that requires internet access--I can't access any websites in Safari, check for software updates, access email using Mac Mail, nothing.

In Safari, I get an error message saying "Operaiong could not be completed. Operation not permitted" (NSPOSIXErrorDomain:1) Please choose Safari > Report Bugs to Apple, note the error number, and describe what you did before you saw this message. (As for what I did before I saw this message, I can only answer, "I turned my back while my toddler was near my laptop... 😟. )

I get a similar message in Mac Mail; in Firefox, just a message saying it can't access the webpage; in software update, nothing at all.

I've looked for answers online; nothing seems to help. It does not seem to be a networking issue; according to Network Diagnostics my connection "appears to be working normally" and the other computers in the house can connect just fine. Nor is it restricted just to Safari, unlike most of the other NSPOSIXError discussions I've found. (I tried reinstalling Safari just in case, but it didn't help.)

Any thoughts? Would reinstalling the OS fix it, do you think? And if so, what do I need to do/know before I take a drastic step like that? (Don't be afraid of talking down to me 🙂.)

MacBook, Mac OS X (10.5.8)

Norton?!

Norton Antivirus (made by Symantec) has a very long and illustrious reputation for mangling Mac OS X systems, sometimes to the point where a complete reinstall is necessary. Among other things, it installs kernel extensions which are known to cause kernel panics and system freezes; it contains known and documented bugs which can silently corrupt Adobe Photoshop and Adobe InDesign files, destroy a user's ability to authenticate as an administrator, and (on PPC systems) can cause Classic to stop functioning; and Symantec has on at least two occasions now released flawed .dat file updates which erroneously report certain critical Mac OS X files as "viruses." (Deleting these "viruses" causes damage to the system that in some cases renders it unbootable.)

Norton has also been reported as damaging iPhone backups.

A major security flaw in Norton has also been noted:

Your problem, hardware or software, may not be exactly the same as that of the original poster of this older thread, and it can be very confusing for everybody if we try to answer more than one question in each thread, which can also result in you applying the wrong advice to your particular problem.

In order for us to give your problem our proper attention to try to solve it, would you kindly start your own thread, describing the trouble you are having in the fullest detail, including completing your details to show what Mac or iDevice you are using, what operating system, and what version of the application in question. Please remember to post in the forum relevant to your hardware or version of OS X. A full list of all the support forums is here:

Try this. Go to Library/Preferences/SystemConfiguration and delete the following (suggest you make copies to the desktop first if in doubt):

com.apple.airport.preferences.plist
NetworkInterfaces.plist
preferences.plist
com.apple.nat.plist

Restart and test

Open HD/Applications/Utilities/Network Utility/Ping and type in 17.112.152.32 (Apple) and click Ping. If you don't get a response back off that try entering your router address in instead of Apple's one and ping that. Report back and we will see where we can go from there

Ok, you've got internet access. Try this, in Terminal (in your Utilities folder) enter

lookupd -flushcache

to flush the DNS cache

Hmm...the command itself runs this time, but still no luck with Safari or Mail. The same error message keeps popping up.

Just a thought but have you looked to see if you have somehow ended up with a proxy enabled?

I did check that, yes--no proxies. It's a very strange problem.

Paste the IP address you pinged earlier (17.112.152.32) into the address bar of one of your browsers and hit return and see if it will connect then.

Assuming you are currently using DHCP for your LAN network addressing test by giving your Mac a fixed IP. Remember if you use a fixed IP that you will need to put in the primary and secondary DNS server addresses of your ISP - you can sometimes cheat and put the IP address of your router in the DNS server field if you don't know them.

Have you tried creating a another user account to test if the problem is purely restricted to your user account or systemwide?

It is system-wide; there is one other account on the computer already, and I created a new one as well--both have the same problem. I'll try your suggestion wiht the DNS server addresses and see what happens.

Hi everybody (sorry to bother you too),
I'm having the same problem with Safari (others browsers work fine).

I also try to overwrite Safari application with the same version (I have a Mac mini, same MacOS), but nothing to do...

Did someone solve this problem?

Thanks
