How do I enable TDM?
Make sure both computers are turned on and awake.
Connect a male-to-male Mini DisplayPort or ThunderBolt cable to each computer.
Press Command-F2 on the keyboard of the iMac being used as a display to enable TDM.
Note: In Keyboard System Preferences, if the checkbox is enabled for "Use all F1, F2, etc. keys as standard functions keys," the key combination changes to Command-Fn-F2.

Using tv as external display for MacBook Air?

Does anyone know how to use a 21.5" Samsung LED TV with 1920x1080 resolution as the external display for a MacBook Air A1369 running OS X 10.6.8 (broken screen)?

I guess you have to buy a Belkin HDMI routing cable. From Thunderbolt/Display port to HDMI.
Then plug it in to your macbook and into your tv. Then press CMD+F1 and voila.
If you still have any problems, i like to hear from you.

Factory resetting a macbook pro 13" 2012 model with 10.9.4 OS running

Hi. I have a macbook pro 13" 2012 model with 10.9.4 OS running. I want to restore it back to factory settings. I tried the command R at the boot but after downloading the os through internet, it does not allow me to install it. The error is shown that i have a newer os and cannot install it to the older one. So is there any other way to do this?
Also when i use the option key at boot up it shows Recovery 10.9 and when i click on that the mac shuts down, every time.
Thanks.

Boot into Internet Recovery mode, ⌘⌥+R, select Disk Utility, and erase and reformat the HD, quit Disk Utility, and restore the OS. That should put the OS the machine shipped with on the HD.

Mini displayPort -- VGA Doesn't work (MacBook Pro 13" 2012)

Hi All,
I just bought a Macbook Pro 13" (cheapest one) and a Mini Displayport adapter to VGA, I want to use it with my Dell Screen but it doesnt work.

Bring it to an Apple store or AASP.

The article you cited refers to The Mac Pro, a 50lb silver tower -- not a notebook computer.
Everymac.com says:
2nd Display Support:
Dual/Mirroring*
2nd Max. Resolution:
2560x1600 (x2*)
Details:
*This model supports a simultaneous maximum resolution up to 2560x1600 on two external displays via Thunderbolt. Alternately, it can support a single display up to 2560x1600 via Thunderbolt and a single display up to 1920x1200 via HDMI. Although it can theoretically power all three external displays, as confirmed by a helpful reader, it runs too hot with three displays connected.
Also see: How many external displays can the Retina Display MacBook Pro models support? What is the maximum supported resolution of each? Are adapters required?
When using other than ThunderBolt displays, the ThunderBolt port is directly compatible with Mini DisplayPort, and can be forced into compatibility (with Single-Link DVI or HDMI up to 1920 wide) with a simple adapter.
To adapt to wider displays, an ACTIVE Dual-Link adapter is needed, about US$100.

Connecting 4k monitor to Macbook Pro retina 2012 mid

I tried to connect to Macbook Pro retina 2012 mid 15 inch 2.7GHZ model. Initially I connected using HDMI to 3840x2160 at 30 hz. I casually changed the resolution to 1080 p from scaled option. Now I no more get the option of scaling to 4k. I am unsure what is the issue over it. When I log into my windows. I am able to log in with my original 4k resolution in 30 HZ. Any guidance would be really great.
2) I read a few forums regarding 4k with 60hz external monitor connection for macbook pro retina 2012 mid. But I couldn't get a clear solution whether it is possible or not. Would be great if someone can show lights on this too.

1- does Apple ever do exchanges for newly released products? I bought my MacBook in jan they came out with new in mar.
If you purchased the product from Apple, not a third party, you have 14 days from the date of purchase to return it for a refund or exchange. You are well past that.
2- if and when Apple comes out with a 4k or 5k thunderbolt display, will it be backwards compatible with my MacBook sich that I can't get the resolutions and 60mhz?
I do not have an answer to that and the Terms of Use for these forums discourages from speculating what Apple may or may not do in the future. Having said that, from a practical business standpoint, backwards compatibility would be a sensible approach. It has been done so in many areas in the past.

I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

It's almost impossible. The new iMacs have a Target Display Mode, but it's built to do that. Without ripping your screen out, finding an acceptable power supply, frame, and whatever electronics to convert a Thunderbolt signal to the screen, the cost will be much larger than buying a cheaper HiDef monitor that runs with an HDMI to Thunderbolt cable to your MacBook 15. In fact, you can sell your 17" MBP for a lot of money, unless it's broken or something, buying you a really sweet monitor.
By the way, I found your answer by searching this forum. I would suggest using the search function here in the futuere.

Hello chrispyw,
If your content is still being displayed incorrectly, I would check the resolution setting for the built in display with this article:
OS X Yosemite: Adjust your display’s resolution
If it keeps happening whenever you use AirPlay then I would use this section of the following article to reset the display system:
Apple computers: Troubleshooting issues with video on internal or external displays
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.

Sterling

Macbook Pro, bought 2012, takes a very long time to start up/restart (5 mins). How do I fix this?

My Macbook Pro, bought 2012, takes a very long time to start up/restart (5 mins) every single time I have shut it down. I try not to shut it down at all now because once or twice, I have got a grey screen, and then nothing. I've held down the power button to shut down again and restart How do I fix all this?

Start up with your built-in Recovery disk by holding down the Command and R keys when starting. Open Disk Utility from there and use it to REPAIR your disk (you've already verified it and it came up with errors).
With any luck, your problems will be solved. While I was there, I would also repair permissions.
Good luck,
Clinton

Can anyone recommend a portable USB 3.0 drive with hardware encryption, compatible with OSX Mountain Lion and Windows 7. I need it for my MacBook Pro 13”, 2012, running Mountain Lion & Windows 7 Ultimate - BootCamp. I’ve heard that the Buffalo MiniStation Encryption does not work with OSX, is that true..? I'd like it to work with both operating systems, using the built in hardware encryption. Thanks

You should be able to copy all the files from your old computer, although it might not work if the old machine didn't have an intel processor. When I got a new Mac a few months ago, I used the migration assistant to copy everything from my old computer's time machine backup disk. All my old pro apps, such as Final Cut Pro 6, work fine on the new machine under Lion.
Later, I wanted to install Soundtrack pro and couldn't do it from the original disks. So I installed it on my old machine and copied the files. It worked perfectly.

HT5037 All of a sudden I can't open my iPhoto library. I get a message that says "To open your library with this version of iPhoto, it first needs to be prepared. It takes me to this page. Bought MacBook Pro 11/2012. Don't have a clue as to version of

All of a sudden I can't open my iPhoto library. I get a message that says "To open your library with this version of iPhoto, it first needs to be prepared. It takes me to this page. Bought MacBook Pro 11/2012. Don't have a clue as to version of IPhoto

Is this library one that you've been using since you bought the MBP? If so and you're running iPhoto 9 then apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with
Option #3, followed by #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
