"Cloned" en0 (hardwired Ethernet) in MacBook Pro Routing table -- how to remedy ?

I have noticed a "cloned" en0 (hardwired Ethernet) in my MacBook Pro's routing-table under Mavericks .
Instead of listing the IPv4-address, in the Terminal's "netstat -nr" command, the cloned-en0 lists "<Link#4>" .
I'm in the U.S., but currently the link translates to a U.K. IP-address .
What is going-on ?

My "netstat -nr" readout -- the MAC-address has been edited :

    Well then when you erased your hard drive, your erased the Recovery partition, also.
    Use Internet Recovery to either restore from your Time Machine backup or reinstall the OS if you don't have a TM Backup.
    It will install the OS that shipped on that Mac. You can then upgrade via the App Store.

  • Save webpage pdf. Using Macbook Pro, 10.7.5. Remedy?

    I'm unable to open a saved webpage pdf. When I click on it to open, the message is: "The file '...' could not be opened because it is empty."  Using Safari, Macbook Pro, 10.7.5. Remedy?

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Macbook Pro Caps Lock. how to relieve? i cant small caps letter use?

    Macbook Pro Caps Lock. how to relieve? i cant small caps letter use?

    I think I have a different problem, but it shares some similar features.
    I just got my MBP back from repair for a dead trackpad/keyboard.
    Things work mostly peachy now, but I noticed that the caps lock feature doesn't work. The caps lock light does come on on both my built-in and external keyboards, but neither produces CAPS when used.
    Searching for this topic on the 'net is difficult nowadays due to a different issue on the new MBP swamping most older discussions.
    In any case, the feature itself is gone-the hardware seems to be working properly. It even gives me the little caps lock warning if I press the caps lock key on the login screen. However, no capital letters are ever produced with them.
    Strange.

  • Laserjet 2100 TN via ethernet to MacBook Pro 2009 (Snow Leopard)

    I've been given an HP Laserjet 2100 TN. It was previously suceessfully used with a MacBook pro via an ethernet cable.
    I'm trying to set it up at home but failing to get it to connect with my MacBook. I'm using Snow Leopard.
    I've read lots of connection tips in discussion forums but not found a solution that works for me.
    I've managed to print a configuration sheet which tells me in printers HP JetSend Address.
    I've tried using this to add the printer through System Preferences but the computer is not connecting with it.
    Do I need a parallel cable or is the ethernet cable enough?
    I think I'm missing something obvious!
    Sarah

    Sorry to post in the wrong place! And thanks for your input. SCSI is a good call - the parallel cable didn't look quite right and that may explain why. Can I add a few more experiences to help explain where I'm at:
    - Snow Leopard seems to think the drivers should be included in the OS, but I don't know how to access them.
    - I found and installed a driver but couldn't find how to access it when adding the printer.
    - When I'm in ADD PRINTER
        - I guess I need an IP address - is this the one I find on printer info?
        - I saw a forum that recommended LPD as best choice for old priters so I'm using that
         - It defaults 'Print using' to Generic Postscript Printer'. I've tried changing it to Generic PCL Laser Printer as it is a laser prointer, but neither help make it work
         - Once I've setup the printer, when I run a test page the printer fails to connect and goes on hold
    I don't think I'm explaining myself very well - mainly because I'm quite out of my depth trying to did this! I can't find anything in the printer handbook which helps. Do you have any advice for a novice trying to add a printer it would be much appreciated.

  • Macbook Pro route probelm after installing 10.4.6

    My wife just unpacked her new Macbook pro -- my first impressed is how fast it was. Amazing machine.
    With the machine set up to 10.4.5 the wirless works flalessly, however after upgrading to 10.4.6 DHCP no longer appears to negotiate an address (the IP address using the network tool is 169.254.189.105) - and yes, I have associated with the same router used with 10.4.5
    I have attempted to manually assign an IP address, gateway, and DNS server to no avail. At that point, I have flushed the routing table and (route flush as root) but I can not ping my gateway...
    10.4.6 on my Powerbook, and her old iBook both work fine It looks like I have a problem unique to the macbookpro.
    I have installed no software on the system except for software on the apple restore DVD's, and the 10.4.6 patch. No other software has been added.

    I would suggest you try downloading the 10.4.6 Combo Updater (Intel) and re-applying the update. Oftentimes using the combo updater can fix problems such as these.
    Be sure to configure Network preferences to use DHCP. It also can't hurt to shutdown everything for about one minute, then restart the cable/DSL modem first and wait for the status light to indicate communication with the ISP, then start the router and wait for the status light to indicate communication with the modem, and last start the Mac.

  • MacBook Pro to TV-- how well does it work?

    The recent announcement of tv.com CBS's streaming of old TV shows (90210, Star Trek, MacGiver, etc.) for the iPhone got me thinking about how to connect the MBP to a TV.
    I've found out that there's a $19 adapter (hmm... should look again at how long the cable is), which is peanuts for trying this, but I'm wondering how well it work.
    Any comments? We have an old 20" JVC tube TV and a 20" Zenith LCD TV, neither high-def, neither digital, both take RCA composite cables, so I assume that's how I'll hook up the video/sound.
    But, am I going to get audio/video glitches, poor streaming (ISP dependent no doubt), restarts, etc.? Or does it generally work OK?
    Note: this is a duplicate post. It was pointed out that this was the better place to post this message!

    There are two factors here. The speed of the computer, and the speed of the Internet. You already acknowledged that Internet speed is ISP dependent, and that's true.
    I have no problem watching standard definition even off of a slow DSL. However, frame rates are rather stuttery if I use my old G4 PowerBook. If I'm using my MacBook Pro, the experience is good enough that you forget you're watching the Internet (don't forget to click the Full Screen button).
    Things change if I click the HD button on the site. This seems to be bandwidth dependent. My home DSL can't keep up, and it stutters. If you want to watch in HD you should have a nice fast cable or fiber connection. The MacBook Pro should have no problem playing back HD streaming if the Internet can feed it fast enough.
    The TV connection part is not a problem. Even the old G4 can do it. Video is routed via DVI>HDMI to the TV, while audio is routed from the laptop into my stereo for nice sound.
    TV sites are very dependent on Flash and JavaScript, and are very aggressive about making sure you see the ads embedded in the shows. The more you use ad blockers etc. like Firefox's NoScript or AdBlock, the more chance a TV site will not work right.

  • Why does my MacBook pro freeze and how do i stop it?

    Hello
    I have recently bought a new MacBook Pro, late 2011 13'' 2.4 GHz. It has started freezing alot. I don't know if it needs more RAM, a problem with the hard drive or faulty application. So I was just wondering if anyone could give me advise on how to stop it and why its happening.
    Thanks

    Is this very recent? Did you install the new Thunderbolt/Ethernet update?

  • Macbook Pro 1.1 how to improve read/write speed

    Hello,
    I am looking to improve the read/write performance of a 2006 2.16 Intel Core Duo Macbook Pro with 2gb RAM (the max), that I use on a specific job in a specific workflow.
    In the workflow there are three retouchers using three different MBPs and transferring files via Ethernet network to a fourth MBP (the one in question) which is used as a dropbox, if you like.
    So the MBP in question has no applications running. Files are saved to it and opened from it and saved back to it.
    How can I improve read/write speed on this MBP under these conditions?
    Would installing an SSD be the answer? Or is it really a processor issue and there's nothing to be done? I figure RAM doesn't really come into it, but in any case 2GB is the max this model can accept.
    Many thanks in advance.

    An SSD would definitely improve read/write speed. However, depending on capacity needed, are you sure you want to sink the money into this machine? Start here:

  • I have 1 GB RAM on an '07 MacBook Pro. 1) How do I check remaining memory? 2) I have Microsoft office 2004 - do I need to buy more RAM to upgrade to '11? 3) I need a new battery ... Is it worth the $$ to buy a new battery, RAM and Microsoft office 2011?

    I have a MacBook Pro from '07 with 1 GB of memory. The battery is shot and my AppleCare has run out. I just upgraded the OS to 10.6.8. But a few questions:
    1 - How do I even check how much memory I have left on this computer?
    2 - How do I check how many battery cycles are left?
    3 - I want to upgrade to Microsoft Office '11 because I don't have Adobe Acrobat to creat pdf's and I need to be able to do this for school... Instead of buying acrobat, I figured I would just upgrade to Office '11 because I can generate pdf's from Word. Roughly how much RAM does Office '11 take up?
    4 - Does Apple still make batteries for this computer (from '07)? How much do they cost?
    5 - How much does 1 more GB of memory cost?
    AND lastly -- is it even worth it to spend the $ on more RAM, a new battery and Office '11?
    Or does it make more sense to just get a new computer entirely? (trying to avoid this).
    ANY help would be sooo appreciated! Thanks.

    1 - How do I even check how much memory I have left on this computer?
    If you're asking how to check to see if you need more RAM, open Activity Monitor and go to the System Memory tab, then compare page outs and page ins.  If page outs is 10% or more of page ins, you probably need more RAM.
    2 - How do I check how many battery cycles are left?
    There's no limit on the number of battery cycles, it's just that the more cycles you've used the more "worn out" your battery gets.  You've got a 4-year-old machine, and if it's still got the original battery, it's probably about time for a replacement battery.  You can check battery health using System Profiler...  look at the Power section under Hardware.
    3 - I want to upgrade to Microsoft Office '11 because I don't have Adobe Acrobat to creat pdf's and I need to be able to do this for school... Instead of buying acrobat, I figured I would just upgrade to Office '11
    You don't need Office 2011 to create PDFs.  Any application capable of printing can create PDFs on a Mac.  Just choose File -> Print, but instead of clicking the Print button in the print dialog, click the PDF button and choose Save As PDF in the menu that appears.
    4 - Does Apple still make batteries for this computer (from '07)? How much do they cost?
    5 - How much does 1 more GB of memory cost?
    I'll "ditto" sig's answers to these.
    AND lastly -- is it even worth it to spend the $ on more RAM, a new battery and Office '11?
    Or does it make more sense to just get a new computer entirely? (trying to avoid this).
    If Office 2004 is still working fine for you, stick with that and don't incur the costs of Office 2011.  As to the RAM, only add more if the test I mentioned above indicates that you need it.  If you buy more RAM when you don't really need it, you won't see much (if any) performance improvement.  That just leaves the battery...  and if the machine is still doing what you need it to do and you don't really need a new machine for anything, you could definitely buy a new battery and get a few more years out of it. 

  • Get the Dell EVDO Express Card working on a Macbook Pro - here's how

    I found this here:
    http://svenontech.com/2006/06/11/get-ev-do-access-on-your-macbook-pro-now-from-v erizon-via-your-xv6700/
    On the Mac side, you’ll first need to pair your XV6700 and Mac to each other. You should be able to do this easily, but if you need some help, check out Apple’s site for direct documentation on how to do this. When pairing, select “Other” device from the list, not “Phone”.
    Once paired, the last screen will ask if you wish to use the device as a modem and headset. Uncheck headset (unless you wish to use your phone to communicate with others on applications such as Skype.) Now follow these instructions for setting up the modem:
    Username: (Your full phone number) [email protected]
    Password: vzw
    Phone Number: #777
    Mode Script: au cdmaOne Bluetooth Adapter
    Leave all check boxes checked
    Click CONTINUE
    Click QUIT
    You’re now all set on the Mac side. You’ll now see a phone with a dot slash icon on your menu bar. Select it and choose “Connect”. Remember to have your XV6700 on, Bluetooth enabled, and the WMmodem application running Bluetooth mode with the START button activated. If all this is the case, you’ll be connected in seconds and your modem icon will display a counter next to it once connected. Enjoy the EV-DO!
    Can someone verify that this works? I have a Dell Card on order.
    MacBook Pro   Mac OS X (10.4.7)  

    David,
    Thanks for the response.
    Before I read this I went to the apple store and tried some BT file transfers to another Mac and experienced the same results. I then went to the Sony store and tested it on a XP laptop and experienced the same speeds. I am able to achieve twice that rate when doing mac to mac BT transfere. I know my MBP has BT 2.0, but I didn't think my first generation Mini was 2.0.
    I am able to sync via USB with Mark/Space's Missingsync, but it doesn't appear that they support DUN. I will email them, to see if they will consider it.
    I just bought my 6700, so I still have the choice to return it. I am not sure if I should get another device that currently supports EVDO DUN via USB or suck it up and hope someone makes a usb dun driver for the 6700.
    Thanks again.
