Optimize iMac for FIOS with Apple Broadband Tuner

I am a recent Mac convert and am trying to optimize my Apple settings for an iMac 27" for Verizon FIOS, I downloaded the Apple Broadband tuner as suggested by Verizon, but do not know how to use it to optimize my settings.
Thank you.

You simply double click on broadband tuner and it sets your sysctl variables to the values shown.  I think these buffer values may be outdated at this point.

  • Apple Broadband Tuner won't install.

    I've tried three different download sites. Using Safari.

    Mac Mini, Mavericks,
    OS X 10.9.1 (13B42)
    1-yr old system
    2.6 GHz Intel Core i7
    16 GB 1600 MHz DDR3
    I did a Verizon speed test while online, in "MyVerizon".  I'm in New York City, Manhattan.  DSL service.  FiOS not available.
    Link to their speedtest: http://my.verizon.com/services/speedtest/
    Results: 8.96MB down, 0.75MB up.
    "Speed Test is complete, here are the recommendations:
    Your computer settings may be slowing you down, select Apple Broadband Tuner to reconfigure your settings and maximize your speeds."
    The link takes you to: http://support.apple.com/downloads/Broadband_Tuner_1_0
    I downloaded it, and tried to install it.  Message: "BroadbandTuner.mpkg" can't be opened because it is from an unidentified developer."
    "...unidentified developer"?
    Its from an Apple site!
    Anyway, I did a little searching and found this post.
    I would like to apply the fix "baltwo" detailed, but I'm not very Mac-terminal-programming savvy.
    I got to terminal, logged in and got to this screen:
    # Tuning network for broadband
    # START
    kern.ipc.maxsockbuf=512000
    net.inet.tcp.sendspace=131072

    So what I don't understand is where and how to ...
    "Add the following lines:

    net.inet.tcp.sendspace=400000
    net.inet.tcp.recvspace=400000
    net.inet.tcp.delayed_ack=0
    net.inet.udp.recvspace=131072
    Then type CONTROL o - it will ask to save, press return key.
    Then type CONTROL x
    Restart the computer and Shazam!"
    I'm much more comfortable working with pc's, using a command window and entering commands.  Even though my first computer was the original 1984 Mac, and still like Mac's, for my business back in the 1980's, I had to go pc, and my learning curve is stuck there.  The Mac Terminal interface and commands are totally foreign to me, so if someone could "hold my hand" and walk me through how to make the changes, I'd be much obliged! 
    And I'm really talking about telling me, keystroke-by-mouse-click, how to do this!
    Many thanks and Happy Holidays!

    How to complain to Apple about this company and how to get a formally answer for problem with Apple agent in Kuwait??

    You did not buy your iphone from an Apple store.  No Apple employee sold you anything.
    Your complaint is not with Apple.  You bought from an unauthorized seller.  Your complain is with that seller.
    As you have been told more than once, Apple has nothing to do with this.

  • Does Apple Broadband Tuner work with Leopard?

    Does anyone know if this works with Leopard? I didn't want to install it if it would screw up the OS. My speed seems bottlenecked at ~5Mbps on a 30Mbps FIOS connection. My speed patched XP box gets ~2.5MB/sec on a download while Leopard gets ~500KB/sec on the same download. Apple should have tuned Leopard's networking better than this.
    Message was edited by: ch0b1ts2600

    My speeds in my leopard have not changed and have not needed to use the broadband tuner my adsl2+ connection just flies.
    That being said the broadband tuner just changes some tcp values and is not recommended for airport connections.
    The system parameters are sysctl variables that are set as follows:
    net.inet.tcp.sendspace: 131072
    net.inet.tcp.recvspace: 358400
    kern.ipc.maxsockbuf: 512000
    The package installer works.
    Once installed you can check to see if the tcp values have changed.
    in the terminal use the command
    sysctl -a
    scroll through the list of values until you find
    net.inet.tcp.sendspace: 131072
    net.inet.tcp.recvspace: 358400
    Then you can see the pkg installer did work.

  • How can I connect HDTV to iMac to use with Apple Color?

    Hey guys,
    I use Color application a lot and the colors don't look the same outside of Color app once they come back to FCP the project is on a dvd...
    Is it possible to use an LCD HDTV with the iMac for Apple Color to see the colors would actually look on a TV?
    If yes, please let me know...
    If not, then is there a workaround?
    Thanks in Advance

    Ben...no one mentioned the MXO2. Talking about the original Matrox MXO...connects via DVI. And it has Component and SDI outputs. Works with professional broadcast monitors. On that note, the MXO2 also has those connections.
    And a GOOD HDTV will work for many non-broadcast workflows. Not everyone does broadcast work, so they don't all need broadcast monitors.
    But, I'm sorry to say that the original MXO doesn't work with the latest batch of iMacs, nor the generation before this. It is old hardware designed for older machines. An iMac just won't work for this purpose. Sorry.

  • Optimize Mac for Gaming with Bootcamp?

    Hi, I have a Mid 2012 MacBook Pro with Windows 7 installed using Bootcamp. Because I'm a student my parents aren't exactly thrilled with the idea of getting me a Gaming PC, but since I'm not a hardcore gamer I think I can make do with what I have. How would I be able to optimize my gaming experience with my Mac? In other words, whether it is with software, or upgrading some hardware, how can I make my Mac usable for gaming. And trust me, I'm not hoping for 60FPS having games on the highest setting kind of thing, something that is decent quality is all I want. I feel that my Mac's current specs and hardware is almost at where I want it, but some optimization to increase efficiency and performance would be really nice. Thanks in advance!

    you are stuck with whatever graphics it has which is usually the main resource.
    Did you buy with just base RAM? which processor? you can't change the cpu.

    A PC with i7-4790 and 16GB + SSD (case, psu, copy of Windows) and X89 motherboard would of course give you freedom and not have to dual boot, plus you get to choose the GPU you need. Windows on Mac often run hot, hotter than they do already. And later you can upgrade just the parts you need to.

  • Which iMac for use with Photoshop CS5 and Lightroom

    Any opinions on which iMac is best for use with Photoshop CS5 and Lightroom. Not sure if the 2.7 i5 with 512 graphics card is Plenty of power or if upgrading to the 3.1 i5 or 3.4 i7 is a wiser choice given the price differences. Appreciate the help

    So I was reading over your post, and even though this is older and has to do with CS5, I have some information for CS6 that will be relevant to your question now that it is time to upgade the software. In general Photoshop has always been more about RAM than Processing power, though that is important too. Until CS5 it could never quite take advantage of what multi-core processors really had to offer, and even the graphics card didn't really effect much of it outside of certain features and the 3D optio
    Now that is no longer true and Adobe can effeciently use all aspects of the computer to give you much better performance.

  • Best router combination for FIOS and Apple TV

    I have a Power PC Mac with Verizon FIOS wired router. I would like to add Apple TV, and I am wondering if I replace my wired router with a wireless one, would that allow me to use Apple TV? If so, what router would anyone recommend as working well with theFIOS connection. I am excited about Apple TV, esp now with YouTube coming aboard. Any feedback is greatly appreciated.
    -- Dave

    Den,
    In my case the ONT and UPS are in the basement. The fiber DOES enter the house to the ONT. The tech when installing the ONT said he was going to put it in the basement regardless of what Verizon wanted (he said easier to service in the basement in bad weather like snow storms or rain) In my case the ONT then goes out over my existing coax to the coax WAN port on the router. If I had cat 5 they would have used that and gone into the ethernet Wan port.
    Installations around my neighborhood vary (I've checked)..it depends on the tech you get the day of installation. If it's in the basement you can examine the fiber wire itself. It appears to be extremely durable.
    I went with Airport Extreme and turned off the wireless in the ActionTech Verizon Modem/Router becuase I'm using Verizon for my own private network in this house which is N exclusively at 2.4 GHZ (my cordless phones are 5 GHZ and don't want interference). My wife still wants Comcast because she doesn't want to change her email address for her business, so to keep the peace I'm paying for 2 internet services. I will however lose the Comcast video in December when Verizon video is available in my town, because the picture is that much better.

  • My Deskjet 3050 J610 will not connect to my Virgin WiFi router for use with Apple Mac laptop.

    I live in the UK and have Broadband access via a Virgin connection and WiFi router. My Apple MacBook laptop connects to the WiFi with no difficulties. However I have an HP Deskjet 3050 J610 printer which will not connect to the router. When I try to connect, the blue light just keeps on flashing but a connection is not found. Consequently my MacBook cannot "see" the printer on the network. Any suggestions? Thanks!

    See if this helps.
    Printer does not maintain wireless connection.

  • A book for parents with Apple TV

    I don't have Blue-ray, HD, or even Apple TV. I do however have an iMac which I created a children's book that I posted to my web gallery in iPhoto. Could you all please read this to your children (it's really funny..I promise) on your Apple TV and let me know how it looks, and if the children liked it. I am also curious to know how you would navigate the pages without a mouse.

    thanks

    I am also curious to know how you would navigate the pages without a mouse.
    The simplest method would be to create some sort a slideshow with a fixed slide delay for viewing. For some, this solution would not be satisfactory
    Could you all please read this to your children (it's really funny..I promise) on your Apple TV and let me know how it looks, and if the children liked it.
    Your main problem is that the slides are much too large. Anything larger than 1280x720 would be scaled to fit within this area. Thus you are just wasting file space. Therefore, I scaled your content to 926x720 and converted it to an image sequence movie playing at the arbitrary rate of 1 frame/10 sec of elapsed time. I then place the content in an MP4 file so I could associate some cover art with the movie and viewed it on my TV. The video plays well, the file is very small, but, as anticipated, the "one size fits all" approach to the time delay is probably not the best answer here. Unfortunately, no grandchildren were visiting today so I did not have a chance to "Kid Test" the results. Not wishing to spend futher time on this project I have posted am upload of the modified file with your content. (Also, you may wish to check slide #18. Did you really want "prodein" instead of "protien" here?)

  • IMac and frustration with apple

    Right so, my iMac started having a hissy fit with the fans being extremely loud. After a few days, I got the boot with the question mark and flashing folder. I took my imac into the apple store, and told the apple genius my problems. He told me the hard drive was dead. So I asked him if the hard drive would cause these problems and he told me yes. I asked if he could check to make sure. He just told me it was the hard drive again. I went out and got it fixed by a certified apple technician, because he told me it would be cheaper. I got a new hard drive, tried to install the OS and it froze and fans went loud half way through. My second attempt was a success, but it froze and loud fans again. Now that I have paid for something that obviously made no difference, and I'm assuming they will now say I need to spend more. Would apple be entitled to repair it for free?

    Welcome to the Apple Discussions!
    The last G5s were built in JAN 2006. Long out of warranty. Apple has no obligation to this machine. If someone other than the Apple Store repaired this Mac, they had an obligation to verify what was wrong with the Mac and actually repair what was wrong. If replacing the HDD did not fix the problem take that up with the repair shop.
