Connecting a MacBook to an external TV source wirelessly

Im not familiar with and would be great if somebody can help me sort out a way to connect to my Samsung Plasma with my MacBook through a wireless type of network. Im currently using a cable, HDMI / DVI to mini DVI to MacBook and it works great for displaying and mirroring the contents on my desktop etc. The biggest problem is I would like some freedom to move about and not be tied to a 6ft. of cable and sit under the TV. I have read a little about the AppleTV, and it sounds like its on the track to doing to what I'm trying but doesn't exactly say that. Is Apple TV my closest option for this, or can I use some type of Airport network to do this?
Help is greatly appreciated..

Hi there and welcome to the forum.
I too tried to do this. I couldn't find a way to connect it wirelessly, but I did come up with another solution that works.
I simply plug my laptop into the tv using the cables you describe, so in effect the tv screen becomes the laptop's monitor. I then simply use a wireless mouse and keyboard to control the machine.
Apple TV is just really a wireless hard drive that can play media through your tv set. So if you just want to view movies and music through the tv then it works fine. If you want to do more though, e.g. use other softwear/use the tv as a larger monitor or play DVDs etc then the Apple TV on its own is not enough. It will not play all types of video either without some conversion work etc.
Hope this helps.

  • Connecting a Macbook to an external display

    My imac broke.
    I have a white macbook 2.16ghz intel core 2 duo with 2 gb of memory.
    While I assume I can connect my macbook to an external monitor, I'm wondering if I can connect it and improve the resolution. I do a lot of work on photoshop and need a resolution of at least 1600 x 1200. My macbook is only 1280x800.
    Is there a special connector I can get to upscale the resolution, or do I need to buy an aluminum macbook.
    Thanks

    Hi emalen: The web link below is for the adapter required to connect a DVI type monitor. It may not be the exact one you need but it will give you the idea of what you are looking for.

  • Connecting a MacBook to an external display or projector

    I have tried to connect my MacBook to a projector and to a TV using the mini-DVI to Video adapter, both with the same poor results. Here's the steps I took:
    - Turned on the TV
    - Connected the video cable to the TV "video in"
    - Connected the video cable to the MacBook with the mini-DVI to vieo adapter
    - Opened the MacBook
    - Turned it on
    The MacBook boots up, the MacBook resolution changes and the video on the TV is distorted, showing essentially three images of the MacBook display. Any attempt to adjust the resolution using system preferences just makes it worse.
    Has anyone had success using a MacBook for presentations using either a TV or a projector and, if so, what procedure do you use to connect?

    Greetings from Hong Kong-
    I have a major presentation to give in a couple of days and have NOT been successful connecting to an external display. I am starting to freak out. Any instructions would be helpful!

  • How to connect a macbook to an external projector?

    I would like to connect my macbook to my school's projector for presentation and it seems the projector cable at school doesn't fit into any slot in my macbook.
    What kind of cable do I need? I remember the cable at school is able to plug into any PC, and the slot looks like a trapezium with a lot of little holes. Is that the VGA?
    I am using a white macbook, 2.4, bought in september 2008.
    thank you very much

    It took a while for me to figure that out too when I switched to a mac xP
    Here's what you need:
    1) MiniDVI-VGA Cable : which can be found at the apple store (http://store.apple.com/us/product/M9320G/A?mco=MTIxODk3Mw)
    It plugs into the port to the left of the FireWire port and allows you to use a PC (VGA) video cable with your macbook.
    2) The VGA (trapezium) cable if you don't already have one dangling off your projector
    3) You'll have to adjust some settings in System Preferences > Displays to get the projector to display your screen correctly.
    happy presenting :]

  • Connecting a Macbook to an External Monitor

    Can anyone tell me what cord I need to purchase to connect my 13 inch Macbook to this LCD monitor that I'm thinking of purchasing?  http://www.bestbuy.com/site/Samsung+-+20%26%2334%3B+Widescreen+Flat-Panel+LCD+HD+Monitor+-+Rose+Blac...
    Thanks!

    If your macbook has a mini displayport (pictured below) plug on it you'd need a mini displayport to VGA or DVI adapter
    That Samsung monitor says it has both VGA and DVI-D inputs. So either this or this should work.

  • How do you connect 2010 Macbook to multiple external displays?

    Has anyone done this? Would love to get get this working. I'm also not using Apple displays. I also want to know what cables and such I would need.

    1.  Your network admins need to provide you with the Nortel Mac VPN client software
    2.  Your network admins need to provide you with the correct settings to enter into the client settings.
    Hence why I said to ask your network admins

  • How do I connect My Macbook Pro screen to my TV wirelessly through Apple TV

    Hi George. AirPlay Mirroring only works with iPads and iPhones. See:
    http://support.apple.com/kb/TS4085
    Now, if you just want to push video content playing in iTunes on your Mac, then go down to the lower right corner of the iTunes window and click the AirPlay icon and select your AppleTV in the list. The content will appear on your AppleTV.
    You must have Home Sharing setup on both iTunes on the Mac and the settings on the AppleTV.

  • Is there a MagSafe 2 compatible portable external power source for the retina display MacBook Pro?

    I’m using a retina display MacBook Pro with the MagSafe 2 connection.   I would like to have a portable external power source to extend the use of my laptop on long field trips where I am away from power sources. Swapping batteries is not an option for this generation of MacBook Pros.  There seem to be many options for PC’s and even iPhones/iPads/iPods but the MagSafe 2 connection seems to be the issue.  I saw one link that suggested buying an Apple MagSafe 2 power adapter and performing surgery on the power cord (using components provided by the vendor) so that the adapter would run on their back up battery.  I was hoping for a more esthetically pleasing solution. Any suggestions?  Does this product exist and I just missed it? Clearly, if a MagSafe(1) compatible external battery existed I could adapt that using the MagSafe to MagSafe 2 converter.

    Sparon,
    I wouldn’t recommend using an underpowered AC adapter with your MacBook Pro. It sounds as though the best solution would be to get a different laptop bag with a sufficiently large side pocket.

  • I have new hard drive in macbook pro(08) and have SATA cable with external power source to old hard drive (10.5.8)via. USB port and newer drive(10.6.8) will not recognize older drive..Do I need to partition newer drive with older disk to recover data?

    I have new HD 750GB Hybrid in 2008 Macbook Pro 17" w/ Snow Leopard 10.6.8  connected to old Hard drive(250GB that had 10.5.8 on it at time of failure) via SATA cable to USB port with external power source.. Computer not acknowledging old HD at all in Disk Utility or otherwise (that I'm aware of)..Do I need to partition New HD and load old(10.5.8) onto partition to recognize older drive for data recovery? Thanks Wayno08

    You do not need to load 10.5.8 onto your new drive in order for a 10.6.8 system to see the contents of a 10.5.8 system.
    You might want to check out the hard drive troubleshooting bootk in the downloads section of this web site:
    http://scsc-online.com
    They also sell a product named Phoenix that can do OS extraction  and volume copying/cloning, but to be honest I don't know if it's appropriate in this case.
    I would suggest the following:
    Open up Terminal.app (under utilities) and type "diskutil list" without the quotes. This is the command line version of Disk Utility. If the external drive doesn't show up at all, then it's likely not connected properly, not getting power, or just plain dead. If it shows up with only a devce name like disk0s16 but no volume it means the drive is seen, the OS just can't make sense of it.
    Assuming the drive shows up, I would try to boot off the original installl disks for the system and run Disk Utility from that. I'm assuming the drive will show up. You'll want to select the option to repair the drive and then perform the option to repair the permissions.
    If the unit isn't showing up, as per step 1, try a different USB port. More importantly with your unit, try it on another side of the unit if possible. If you read the book I referenced above, some of those units have I/O boards that are separated from the logic board. If the cable from the logic board to the I/O card goes bad or has problems, which isn't all that uncommon, some or all of the ports on the I/O card may appear to be bad as well. If you use a USB port on another side, it would be routing out of a completely different I/O path, so that's a potential problem.
    If the drive is only seen with a device name such as disk0s16, it's likely either the index files are corrupt beyond Disk Utility's ability to see them. The  only thing that I think would help would be a product named DIsk Warrior, but I can't guarantee that.
    Disk Warrior can be found at:
    http://www.alsoft.com/diskwarrior/
    The company that I linked in the first link above also makes a product named Scannerz that does HD and system testing. The Scannerz/Disk Warrior combination make a good pair because the complement each other....Scannerz does what Disk Warriror can't and Disk Warrior does what Scannerz can't. However, at this point I'm not too sure getting a tool like Scannerz would be of much use because it sounds like the  damage has already been done.
    Let us know what happens.

  • MacBook Air USB external drive power source

    I have a LaCie 250GB USB external drive on my MacBook Air and the computer is not being able to power the drive without me connecting the hard drive to an external power source. when the drive was had about 80GB of data it would do it, now that the drive has about 180GB of data, it does not work. Can anybody recommend a solution or an external drive that can hold at least 250GB that can be powered by the MacBook Air without need for external power source?

    I have the same time of problem. Although, it's mentioned a using a self powered hub. However, I find this did not work. Apple states that the single usb port on the MBA is high powered to give the ext. super drive they sell the power it needs to connect to the MBA. What I have noticed is no matter which USB self powered hub I use I get the same results. The MBA reports that one or more devices is drawing too much power. Although, the powered hub is supposed to provide power to those devices that require power over USB. I should also mention, all I am connecting are two USB devices. 1 ext. Verbatim 500 Gig Drive. and my iPhone. Since the MBA has only 120 gig drive I had to move all of my movies etc. to the Ext. 500 now if I want to sync my phone or move a movie to the phone I get the errors.

  • Excel SSAS Tabular error: An error occurred during an attempt to establish a connection to the external data source

    Hello there,
    I have an Excel report I created which works perfectly fine on my dev environment, but fails on my test environment when I try to do a data refresh.
    The key difference between both dev and test environments is that in dev, everything is installed in one server:
    SharePoint 2013
    SQL 2012: Database Instance, SSAS Instance, SSRS for SharePoint, SSAS POWERPIVOT instance (Powerpivot for SharePoint).
    In my test and production environments, the architecture is different:
    SQL DB Servers in High Availability (irrelevant for this report since it is connecting to the tabular model, just FYI)
    SQL SSAS Tabular server (contains a tabular model that processes data from the SQL DBs).
    2x SharePoint Application Servers (we installed both SSRS and PowerPivot for SharePoint on these servers)
    2x SharePoint FrontEnd Servers (contain the SSRS and PowerPivot add-ins).
    Now in dev, test and production, I can run PowerPivot reports that have been created in SharePoint without any issues. Those reports can access the SSAS Tabular model without any issues, and perform data refresh and OLAP functions (slicing, dicing, etc).
    The problem is with Excel reports (i.e. .xlsx files) uploaded to SharePoint. While I can open them, I am having a hard time performing a data refresh. The error I get is:
    "An error occurred during an attempt to establish a connection to the external data source [...]"
    I ran SQL Profiler on my SSAS Server where the Tabular instance is and I noticed that every time I try to perform a data refresh, I get the following entries:
    Every time I try to perform a data refresh, two entries under the user name ANONYMOUS LOGON.
    Since things work without any issues on my single-server dev environment, I tried running SQL Server Profiler there as well to see what I get.
    As you can see from the above, in the dev environment the query runs without any issues and the user name logged is in fact my username from the dev environment domain. I also have a separated user for the test domain, and another for the production domain.
    Now upon some preliminary investigation I believe this has something to do with the data connection settings in Excel and the usage (or no usage) of secure store. This is what I can vouch for so far:
    Library containing reports is configured as trusted in SharePoint Central Admin.
    Library containing data connections is configured as trusted in SharePoint Central Admin.
    The Data Provider referenced in the Excel report (MSOLAP.5) is configured as trusted in SharePoint Central Admin.
    In the Excel report, the Excel Services authentication settings is set as "use authenticated user's account". This wortks fine in the DEV environment.
    Concerning SecureStore, PowerPivot Configurator has configured it the PowerPivotUnnattendedAccount application ID in all the environments. There is
    NO configuration of an Application ID for Excel Services in any of the environments (Dev, test or production). Altough I reckon this is where the solution lies, I am not 100% sure as to why it fails in test and prod. But as I read what I am
    writing, I reckon this is because of the authentication "hops" through servers. Am I right in my assumption?
    Could someone please advise what am I doing wrong in this case? If it is the fact that I am missing an Secure Store entry for Excel Services, I am wondering if someone could advise me on how to set ip up? My confusion is around the "Target Application
    Type" setting.
    Thank you for your time.
    Regards,
    P.

    Hi Rameshwar,
    PowerPivot workbooks contain embedded data connections. To support workbook interaction through slicers and filters, Excel Services must be configured to allow external data access through embedded connection information. External data access is required
    for retrieving PowerPivot data that is loaded on PowerPivot servers in the farm. Please refer to the steps below to solve this issue:
    In Central Administration, in Application Management, click Manage service applications.
    Click Excel Services Application.
    Click Trusted File Location.
    Click http:// or the location you want to configure.
    In External Data, in Allow External Data, click Trusted data connection libraries and embedded.
    Click OK.
    For more information, please see:
    Create a trusted location for PowerPivot sites in Central Administration:
    http://msdn.microsoft.com/en-us/library/ee637428.aspx
    Another reason is Excel Services returns this error when you query PowerPivot data in an Excel workbook that is published to SharePoint, and the SharePoint environment does not have a PowerPivot for SharePoint server, or the SQL Server Analysis
    Services (PowerPivot) service is stopped. Please check this document:
    http://technet.microsoft.com/en-us/library/ff487858(v=sql.110).aspx
    Finally, here is a good article regarding how to troubleshoot PowerPivot data refresh for your reference. Please see:

  • EXACTLY what cable(s) do I need to connect my MacBook Pro (early 2011) to an external display with a 2560x1440 resolution?

    I am trying to connect my MacBook Pro (early 2011 w/ Intel HD 3000/ 384Mb) to an external display with a 2560x1440 resolution. Specifically, what cable/connections do I need to display at this resolution? I cannot get the display to work using a "Thunderbolt to HDMI" or a "Thunderbolt to DVI" connector.  Note:  I used both older and newer (uni-directional) HDMI cables on the first config, and a Dual-link DVI cable on the second config.   Apple specs state this is possible ( support.apple.com/kb/SP619 ), but I am at a loss as to how this can be done.  Thanks in advance for the help!

    You use a Mini DisplayPort to either HDMI or dual-link DVI adapter. If that component doesn't work, something's wrong with either the cable or something else in the connection.

  • Problems connecting my MacBook Pro to an external monitor

    For the past 2 years, I have regularly connected my MacBook Pro to an external monitor (Dell SR2320L) using a VGA cable. When I do so, the picture  automatically comes up in the maximum resolution of the external monitor (1920 x 1080). However, just in the past few weeks, the picture on my external monitor automatically comes up in 1600 x 1200 instead.  When I click on the display menu in the upper right corner of my screen, there isn't even an option for 1920 x 1080 anymore.  I've tried restarting my computer and even unplugging and replugging in the cable, but nothing seems to fix the problem. However, on at least some occasions, the problem seems to fix itself after about a day or so of use, and the picture reverts back to 1920 x 1080. I should note a couple of things: when I connect another MacBook to my monitor, the display automatically comes up in 1920 x 1080. And when I connect my Macbook to a different display, I have the same problem as I have with my display. So I think the issue is definitely with my computer, not my monitor. Does anyone have a suggestion about how to solve this problem? Or, when the problem arises, is there anything I can do to reset the display to 1920 x 1080 other than waiting for the problem to fix itself? Any suggestions woudl be greatly appreciated!

    Hi bonfig,
    If you are having issues with the external display settings on your MacBook Pro, it may be worth going throught the following article, in particular the portion about resetting the SMC and PRAM:

  • How can I restore files from a time machine back-up of my iMac to an EXTERNAL hard drive connected to MacBook Pro. Using Migrat

    I would like to restore files from a time machine back-up of my iMac to an EXTERNAL hard drive connected to MacBook Pro. When I tried using Migration Assistant it only gives me my internal hard drive as an option to restore to. The internal hard drive on my macbook isnt large enough to store the files.

    Welcome to Apple Support Communities
    OS X can only restore data to the drive where Time Machine backed up files from.
    If you want to restore files from the Time Machine backup onto an external drive, your only option is to access to the Time Machine drive manually (open a Finder window and choose your Time Machine drive in the Finder sidebar), navigate through its folders and copy the files you want to the external drive

  • How do I configure my timecapsule to back up an external drive connected to macbook?

    How do I configure my timecapsule to back up an external drive connected to macbook?

    First, insure that the external drive has been formatted in Mac OS Extended Journaled
    If it's not, and you already have data on the drive, you will need to move that data to another temporary storage location....as the format to Mac OS Extended (Journaled) will erase everything on the drive. Once the drive has been formatted, move the data from the temporary storage location back to the external drive
    Click the Time Machine clock icon at the top of the screen
    Click Time Machine Preferences
    Click Options
    Click the name of the external drive to highlight it, and then click the - (minus) button at the bottom of the list to remove the drive from the list of "excluded" items for backup
    The drive will now be backed up by Time Machine on the next and all subsequent backups
