Misled by Diagnostic help from Mac OS when having an ethernet-problem

I just solved a nasty problem that took me almost a day and that was caused by a wrong message from OS (10.4.5).
What happened:
Along with the move of my mac mini to another room in the house, I had to redirect the ethernet-cable for my adsl.
After doing this I connected my computer and adsl worked fine. The next day however, my adsl-connection had gone! I assumed it were the cables or the connectors that had not been properly fixed and might have been set loose due to some moving of furniture after the initial fixing. I checked the fixings, replaced the R-45 connector and took off a piece of cable that looked (just a tiny bit) damaged. But after all this, the connection still wasn't there.
Now, there is a diagnostic help that appears in the Safari-browser when you don't have a connection. This diagnostic help issued the message that the 'ethernet-cable is not connected'. It stunned me, because all connections seemed well by now.
Then, I took my computer and hooked it onto another cable in the house that I knew was working well: same thing! No connection. After that I realised my OS had fooled me. It was not the cable, nor the connectors, it was a wrong message from diagnostic help! I ran network configuration assistant and the thing worked in 2 minutes. So I wasted hours on messing with cables and 13 euros on a connector, because of a faulty message.
Is there a moderator that can explain why this has happened as it did? maybe something to fix in an upgrade?

Sounds like a bad preference file. Move the com.apple.installer.plist file out of /username/Library/Preferences/ to your Desktop. Now, mount the image. If that works, problem solved. If not, create a new admin user account, log into it, and try to mount the image. If it works, then you'll have to resolve the conflict within the original account. Report back with the results.

  • Getting Help from Mac?

    How does anyone get help from Mac? I've listed four questions with not a single suggestion or opinion. I'm not able to find a way to contact tech-help or any email address to discuss any problem with apple software. Reading the threat, if apple doesn't like my comments or question I'm out of here doesn't instill a warm feeling. I've doubled the cost of my MAC with the software I've added. But if I don't talk nice you will drop me? How about you provide some help to fix your software problems and I will compliment you on how great you are. My home is in Atlanta but I am stationed overseas hence I can not make phone calls.

    Hi Jerry,
    If I have questions about using my computer I first check the Mac Help items, as you have done. I then do a web search as probably somebody has encountered the problem before. Even these discussions get included in the searched sites, and I have seen my own posts appear in a matter of minutes. There are other sites where Mac users post questions so there is a pretty large set of answers out there. Finally, if I don't see an answer anywhere I post a question here on the appropriate forum.
    You should realize that the forums are populated almost exclusively by other Mac uers and not Apple employees, but you still get pretty good answers by people who have been using Macs for years and years. Sometimes you'll stump us, but if you provide complete background information in your question I will usually see somebody take a stab at it.
    One thing you should note is that the Discussions, and even this Forum, is not an effective way for direct feedback to Apple about customer service, etc. (this feedback forum is for feedback about the Discussions). I almost never see an Apple employee respond on the Discussions since it is intended as a consumer to consumer interface. There are better ways to contact Apple itself listed on the [site map|http://www.apple.com/sitemap>.

  • I have a mac, would like to upgrade to mountain lion from mac os x, anybody experienced any problems after this upgrade, thanks

    i have a mac, would like to upgrade to mountain lion from mac os x, anybody experienced any problems after this upgrade, thanks

    Check that your computer is compatible with Mountain Lion.
    To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
    iMac (Mid 2007 or newer) model number 7,1 or higher
    MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
    MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
    MacBook Air (Late 2008 or newer) model number 2,1 or higher
    Mac mini (Early 2009 or newer) model number 3,1 or higher
    Mac Pro (Early 2008 or newer) model number 3,1 or higher
    Xserve (Early 2009) model number 3,1 or higher
    Your Mac needs:
    OS X v10.6.8 or OS X Lion already installed
    2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
    8 GB or more of available space
    If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again.  You can make a bootable DVD/USB stick to install using this free program.
    Bootable Drive DVD or USB Flash Drive – Lion Diskmaker
    Our 2 computers haven't experienced any significant problems, even though others have. I find it much better than 10.7 Lion, which I used for a week before reverting to 10.6.8
    Mavericks is supposed to be released this fall, so you may want to wait.

  • Switching iTunes from mac to pc - having problems - help, please!!!!

    I have an iPod and a Shuffle and all my music is in iTunes on my mac.
    I want to now have my iTunes on my pc instead. I understand my iPod is not compatible, so I plan to re-format it once I get iTunes all squared away.
    I downloaded iTunes onto my pc and...
    Issue #1: When I open i Tunes I receive an error (no code) that says: "The registry settings used by the iTunes drivers for importing and burning CDs and DVDs are missing. This can happen as a result of installing other CD burning software. Please reinstall iTunes." I can hit "ok" on the message and iTunes opens up.
    I uninstalled and reinstalled. Same message. True, I have other CD burning software on the computer but don't want to delete it. Don't know if this is really an issue except for having to bypass that error message every time I open iTunes....
    Issue #2: I Exported my iTunes library from the mac onto an external hard drive formated in fat32 thinking I could either import the music into iTunes on my pc, or, even better, use the external drive to store the music for use with iTunes on my pc.
    Ideally, I'd store the music on the external hard drive and use iTunes on my PC with my iPod and Shuffle.
    BUT, after searching the support site and discussions and trying the suggestions I found, I stil have no music showing up in iTunes on the pc.
    Can anyone help me? I've spent quite a bit of time on this already and I really can't keep wasting the time. Thank you!!!!!!!!!

    First you will want to look for updates to your other CD burning programs that will possiably fix this issue or try uninstalling reinstalling both iTUnes and quicktime.
    Im not that mac savy, but on the windows side of things, iTUnes is very picky on what is where.you can recreat the Library on your PC if the file you saved from the mac is a "iTUnes Music Library.xml" file but that would be a hard thing and a mess cuz iTUnes for windows doesn't "Watch" folders. So if that Nickelback song you have was on C:/Mac/Music or however a mac does folders, then it would have to be in the EXACT location in windows. If not your going to have a very sloppy library full of ! marks.
    But if you want you can recreate the library following these instructions http://docs.info.apple.com/article.html?artnum=93313

  • Officejet A909a prints from mac but when from windows "out of paper" message appears.

    I have an older 8500 which has been very loyal to me and I have looking after it well, which is now pushing 4000 pages.  However i went to print a file from my Windows 7 PC yesterday which is connected via usb, and it wouldnt print saying it was out of paper (which it wasn't) about half full . So i tried again no luck. UN-installed then reinstalled the printer still noting. went to my work laptop (windows 7) which is connected wirelessly through the network, same again "no paper" message appears. i thought this is strange turned it off back on still nothing even after disconnecting it from the mains for a few minutes, nothing the same message still appears. 
    However, my son has a mac book pro and he just printed his coursework off the printer effortlessly through my network. so i know the printer is fine especially as i have now printed self test pages off through the printer itself.
    I have no idea what to do now, as i have tried uninstalling then installing, printing via usb and network. and when i say "out of paper" i mean the printer receives the print command from my computer as it tries to feed paper a few times but cant pick it up also i have tried with various paper levels in the printer (full, half, about 20 pages, 1 single page)
    Please help.

    Hello @Dangerous97,
    I understand that when printing from your 2 Windows 7 computers you receive an 'out of paper' message after your HP Officejet Pro 8500 All-in-One Printer struggles and fails to pick up paper. However, you are able to print from a Mac computer. This is very unusual behaviour!  I would like to assist you today with resolving this issue. Also, thank you for including that you are able to print self-test pages from the printer with no issues as well.
    Generally, 'out of paper' messages are caused by a hardware issue with the printer itself. Because you are able to print standalone to your printer and from a Mac, there may be an issue with the documents that you're trying to print from your Windows 7 computer or a programming issue with your printer.
    With that being said, to start I would like you to click here to download and install the latest programming Firmware Update on your printer. Once the website opens select the Download button on the top left. Once the download is complete, please follow any onscreen instructions to send the update to your printer.
    Once the Firmware has been successfully updated, please test printing again.
    Please respond to this post with the result of the Firmware Update. Good luck!

  • Emails vanish from .mac account when deleting them from iphone!

    The problem we are having is that on my wifes minimac when she deletes emails on her iphone they vanish from her desktop .mac mail programme.. not good!
    But.... my email on my G5 .mac mail programme account is set to .Mac IMAP and my emails that come into my iphone dont get deleted from my desktop .mac mail programme.
    How can i set up her account to not delete the mails from her minimac mail account?
    Her email is an additional account - whereas my account is the master account!
    can anyone help?

    If you are accessing the account as an IMAP account with the email client on your computer as well as with the iPhone's email client, all server stored mailboxes are kept synchronized automatically between the email clients used to access the account. This cannot be changed. If you delete a message from the account's Inbox mailbox with the iPhone's email client, the message will no longer be available in the account's Inbox mailbox when checking the account with your computer's email client and vice-versa.
    This is the nature of an IMAP account which cannot be changed.
    If this is not the same for your account, this indicates you are accessing the account as a POP account with one or both email clients used to access the account.

  • Windows authentication fails from Mac browser when LB is in between

    (1)     A new instance of Windows server 2008 R2 is taken and IIS server is installed.
    On IIS server, ‘Windows Authentication’ is enabled and all the other authentication (anonymous, basic) is disabled.
    (2)     From Safari browser on Mac, a IIS resource (protected by Windows Authentication) is accessed by directly accessing IIS server. The resource access is successful.
    (3)     Now a Load Balancer is configured in front of IIS server.
    (4)     From Safari browser on Mac, a IIS resource (protected by Windows Authentication) is accessed by accessing load balancer. Here IIS server prompts for username and password.
    Seems that authentication negotiation is failing between Mac browser and IIS when LB is in between. Can somebody pls know the reason / resolution for this issue ?
    Thanks

    I was just helping someone with this same issue, and found this post searching for answers. I think it's a problem with your web hosting provider. It looks like whois is saying you both use readyhosting.net, is that right?
    If you go into the developer options and override the User Agent string, you can make the issue start and stop. When the user agent string starts with "Mozilla/5.0 (Windows NT 6.1", then the page with show the error message. If it starts with anything else, then it works fine.
    This, and the fact that you did not make any changes to your site makes it sound like your hosting provider changed something. You probably need to have them fix it somehow.

  • Hi need help from Mac Guru

    Firefox doesn't know how to open this address, because the protocol (rtmp) isn't associated with any program.
    i need to open this address from safari or firefox or any other Software
    "rtmp://127.0.0.1/videowhisper"
    but it doesn't get loaded.
    i got this message from fire fox
    Firefox doesn't know how to open this address, because the protocol (rtmp) isn't associated with any program.
    safari error message
    Safari can’t open the specified address.
    Safari can’t open “rtmp://127.0.0.1/videowhisper” because Mac OS X doesn’t recognize Internet addresses starting with “rtmp:”.
    any one can help m e........?

    rtmp by itself isn't understood by a browser. See this page:
    http://en.wikipedia.org/wiki/RealTime_MessagingProtocol
    127.0.0.1 is a 'loopback' address:
    This page: http://en.wikipedia.org/wiki/Localhost
    says
    'Localhost always translates to the loopback IP address 127.0.0.1 in IPv4, or ::1 in IPv6.[3]. Localhost is specified where one would otherwise use the hostname of a computer. For example, directing a web browser installed on a system running an HTTP server to http://localhost will display the home page of the local web site, provided the server is configured to service the loopback interface.'

  • Problem printing from Mac to Officejet J3680 on Ethernet

    I have three computers (two PC's and one Mac) and the Officejet set up on an ATT U-Wire network. The Officejet is connected to one of the PC's.
    I was able to print from all three until recently. I physically switched the places of the Mac and one of the PC's (not the one with the printer connected). That's all I did. Now, when I try to print from the Mac, the job just sits there in the queue. I can still print form both PC's. I tried restarting everything, reinstalled the drivers on the Mac, but nothing works.
    When I send a page from the Mac, the printer sounds like it is going to print but nothing happens. It was printing fine before I moved it. The Mac is now in another room that is farther away from the printer (about 50 feet) but I don't see how that matters. I tried different documents from different programs (including the test page) but nothing prints. Like I said, the printer sounds like it is going to print but just runs out of gas or something. No paper jams etc. It prints fine from both PC's.
    Anyone have any ideas? Thanks in advance.

    I forgot to mention that I cleared all the print queues prior to sending a new job. **bleep**?

  • Unable to stream movies from mac

    This problem is making my AppleTV almost unusable.
    Never had a problem playing movies stored on my iTunes on my MacBook Pro on the AppleTV until the last update.  Now when I attempt to select a movie, it takes upwards of 10 minutes for the movie to start playing.
    I've done all the basic troubleshooting I've seen online.  I have an Airport Extreme on the network running 802.11n, the signal strength on the AppleTV is excellent, the MacBook Pro has excellent signal strength (all wireless), I've checked for updates, verified network settings.  Not sure what else to do.  I used to have no problems at all watching movies on the AppleTV, now it's painful.
    I have crappy Satellite Internet, but have had that for years, although I can stream a video from youtube over my Satellite Internet better than watching a video stored on my Mac.

    I'm having a similar problem with my rented movies.  I rented a movie from my iMac, and am trying to view it on my Apple TV, and I'm getting the error message that the content could not be loaded.  I get the flower petal circle indicator, then the screen switches to what looks like the movie starting (the movie time indicator is now at the bottom of the screen), and then I get the error message. 

  • Going from MAC to PC, How to keep songs on my iPOD?

    I have recently switched from Mac to PC.
    I have problem in keeping my songs on iPOD when connecting to my new PC?
    How do I keep my music? and start sync with my new PC instead?

    "I have recently switched from Mac to PC."
    Oh dear.
    "I have problem in keeping my songs on iPOD when connecting to my new PC?"
    Well a Mac formatted iPod cannot be read by a pc without the use of 3rd party software (such as XPlay2), and of course if you reformat the iPod for pc use, you'll lose the songs.
    Do you still have access to the Mac, or are your songs on the iPod only?

    OK. If you believe that.
    When the disk is starting to die it can be bad for a moment and then be good for a while. If there was no problem while you were checking it of course it shows up good.
    I tell you those are the signs of a disk that is about to die.
