MacBook Pro(Mid 2012) Can't connect to my Dynex TV with mini display port to VGA adapter
I have a MacBook Pro(Mid 2012, running OS X 10.9.4) and I recently just bought a mini display port to VGA adapter so I could hook it up to my dynex TV but when I connect everything my TV says no signal. Do I need to do something in settings?

Can I use a mini display port to VGA adapter and then a VGA to av adapter to connect my MacBook pro to my standard definition tv?
No. You need a converter box like this to go with your MDP-VGA adapter:

I have a Samsung VGA Monitor connected to my MacBook Pro using the Mini Display Port to VGA Adapter. How do I configure the computer so that it doesn't sleep when I close the lid of the computer.
Hi alangium,

Resetting your computer's PRAM should restore your Macbook Pro's screen appearance.

This article may provide some information about your Mini DisplayPort to AVI adapter. Have you tried to connect a different VGA monitor to your Macbook to see if you get the same results?

http://support.apple.com/kb/HT3382
18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

How can I detect displays?
If the detect displays option is not available, hold down the Option key while you are in the Display pane.
How do I select additional resolutions on my display?
You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.
I hope this information helps ....

My Macbook Pro (Mid-2012) won't connect to an external display using my MiniDP to VGA Cable.
I'm on a Macbook Pro (Mid-2012) on Mac OS X 10.8.3 (currently downloading the update to 8.4). When I plug in my Mini Displayport to VGA adapter to my Mac, the screen flickers blue for a second and the Display Settings window detects the other monitor and allows me to rearrange the screen, but it does not project anything onto the other monitor. However, I tried connecting an Apple Thunderbolt Monitor to this computer today, and it worked. This wasn't a problem before, as I was able to connect this Mac to other LCD projects before. Furthermore, I don't think it's an issue with the adapter either because it's relatively new. I also tried plugging in the adapter of another Mac (which was working fine) into my Mac, but it didn't work either.
Here's what I've tried:
1. Restarting the computer with everything plugged in
2. Pressing Command + F1 when it's plugged
Any advice would be helpful!Hi lancekatigbak,
If you're having issues with the display out on your MacBook Pro, you may want to take a look at the troubleshooting steps in the following article:

I bought mini-DP to DVI frome Apple several monthes ago and it worked well in that time until yesterday the external monitor show me no signal sign. Other PCs were connected with the same cable and monitor and they are fine. I am wondering there is something wrong in the adaptor or macbook pro. Furthermore I found the external monitor can display nornally when I switched to 9400 graphic card and used mini-DP to VGA adapter. If I switch to 9600GT no signal again. If I switch 9400 using mini-DVI, it is shown on the external screening: Out of range... In a word, In the mode of 9600GT, mac can not recognise external monitor(I can not detect it in the systerm preference even I press detect display buttun) and 9400 works in VGA mode. However when I connect adapter to mac, the screen showed blue flash.
I reseted SMC, no use; I created a new account or enter mac to safe mode, no use; so far I did not reseted PRAM beacuse of something wrong of my system. I am downlaoding Mountain Lion OS and will install it. Then I will reset PRAM and try again.
I do not know whether I shoud change the adapter or the single-link DVI cable to dual-link. Someone said it is useful in their condition. I tried some methods from BBS, such as connected when devices were off and then open, and so on. I failed.
Any suggestion for this problem?
Addition: OS: 10.7.4(Lion)I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure. Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous). However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
Hope that htis helps. -
Mini Display Port to VGA adapter with Mac Pro
Just as a word of advice if you're thinking of buying a new Mac Pro and planning on hooking it up to dual VGA displays at their native resolutions - don't.
Apple claim it will support 3 VGA displays. That might be true in a very loose sense but not in the sense that you'll actually be able to work with it.
My experience (all using same adapter, cables and monitors):
*Mac Pro - Dual screen set up*
1 x LG Flatron W2242S connected via DVI > VGA adapter - offers native resolution (1680x1050)
1 x LG Flatron W2242S connected via Mini Display > VGA adapter - does not offer native resolution
*Mac Pro - Dual* screen set up*
1 x Iiyama E2472HD connected via DVI - offers native resolution (1920x1080)
1 x Iiyama E2472HD connected via Mini Display > VGA adapter - offers native resolution (1920x1080) but displays it pillar boxed (i.e. squashed)
*MacBook Pro - Dual screen set up*
1 x laptop screen - fine (obviously)
1 x LG Flatron W2242S connected via Mini Display > VGA adapter - offers native res (1680x1050)
The conclusions being that despite having the exact same configuration in terms of adapters and monitors my £3k Mac Pro is incapable of doing what my MacBook Pro can.
I have spoken to Apple about this and they have admitted it is a limitation and suggested buying DVI monitors along with the Dual Link DVI adapter (£70).
Not ideal.
Message was edited by: chr1shardcastleDVI-I provides the direct Analog signals needed to get VGA using a very simple adapter.
DsiplayPort (and its Mini variant) requires a converter to produce VGA or Dual-Link DVI, and the converter must be active/powered. There is a lot of logic in those converters. It may also have additional limitations.
In general, you should hook your highest resolution, most demanding display up with the DVI to VGA adapter.If running two Mini DisplayPort displays, ALL MiniDisplayPort converters must be active/powered. -
I tried to download a firmware update but my MBA said the update was unsupported. I'm not super tech, so I'm kind of at a loss. Ultimately, I want to mirror my iPad to the classroom projector so that I can move around while I teach.

Thanks for visiting Apple Support Communities.
If your MacBook Air and projector are not communicating, I recommend the troubleshooting tips found in this article:

Start with these steps:
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:

After the upgrade to iOS 8.1.2 in iPhone 5s and OS X 10.1.1 Yosemite (MacBook Pro Mid 2012) can not connect my iPhone 5s to the MacBook, the iPhone tells me: "The MacBook is incompatible" or the message "Connection Error, Make sure the Mac is turned on and is within range" even the iPhone being close to the Mac. Otherwise with the updated iPad 2 (iOS 8.1.2) is connected via bluetooth to the MacBook without any problems, Even the iPad 2 does not detect the iPhone bluetooth.

If you are attempting to use Handoff/Continuity, that does involve Bluetooth but the devices are NOT paired; Bluetooth just needs to be on and the devices in range of each other. The following may help with Handoff/Continuity issues: http://support.apple.com/kb/TS5458 -
My Macbook pro Mid 2012 Model Seems to be using too much RAM
Hello everybody, I recenlty bought a Macbook pro Mid 2012 Model and I absolutely fell in love with it! I use it everyday for school, work, and for my musical hobby.
I haven't had a single problem with it until recently, and it seems like the RAM memory is being all used up without me even running programs. This problem barely started rougly 2-3 weeks ago and it's becoming annoying. I do plan to upgrade the ram soon seeing as the extra RAM will help run my engineering software I'm going to be using.
Anywho I'm just looking for tips, suggestions or answers as to why this problem is occuring. Also heard from a fellow employee that Google Chrome can cause this problem with RAM and battery life as well.Stop using Chrome for any number of reasons and stick to Safari. An aspect of OS X memory management is to take over as much memory as possible in order to better manage the memory, however, this does not mean you are running out of memory. You only run out of memory when you try to run too many applications concurrently given the amount of RAM you have. You will know when that happens because the computer will slow down, you will see the beachball a lot, everything you do takes forever, and the hard drive will be grinding away.
About OS X Memory Management and Usage
Using Activity Monitor to read System Memory & determine how much RAM is used
OS X Mavericks- About Activity Monitor
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs. -

Can I use my macbook pro mid 2012 as an external display using thunderbolt port
Hi,
I want to use my macbook pro (mid 2012) screen as an external display for a raspberry pi using a HDMI to Thunderbolt cable, via the thunderbolt port on the macbook pro. Would this be possible? Can the macbook pro's thunder bolt port act as an input and is any additional software required?
I look forward to hearing from you.
Thanks in advance!Welcome to Apple Support Communities
You are referring to Target Display mode. Target Display mode can only be used in 27-inch iMacs and iMacs with Thunderbolt, not MacBooks Pro > http://support.apple.com/kb/PH11302
Unfortunately, you can't use the MacBook Pro as a display. It doesn't support the monitor mode -
Migration Assistant can't find External HD on MacBook Pro Mid-2012
Hi, I have a MacBook Pro Mid-2012 running OS X Mountain Lion 10.8.2 and I am trying to use Migration Assistant to transfer Time Machine backups that are on my external hard drive, that I backed up from my old MacBook Mid-2010. The problem I am having is that Migration Assistant can't find my external hard drive. My MacBook Pro can find it when I plug it in (I see it in Finder), but Migration Assistant can't. Can anyone help or should I go to the Apple Store? I need help with this problem as soon as possible.
Thanks in advance,
- Daniel Since no one replied I figured out how to do it myself.
1.) First I plugged in my external hard drive with my Time Machine backups on them, then I opened Finder and click on my external hard drive under devices.
2.) Next I clicked on and opened the folder named "Backups.backupdb"
3.) Once inside that folder I could see folders with the backups from Time Machine and all of the folders names were the date I backed up that backup. I clicked and opended the lastest backup folder.
4.) Inside that folder, I clicked and opened the folder named "Macintosh HD"
5.) Inside that folder, I clicked and opended the folder named "Users"
6.) Inside that folder, I clicked and opended the folder named "Daniel" which was my Username on my previous Mac.
7.) Finally I could see and access all my folders from my Time Machine backups from my previous Mac.
Keep in mind this is only helpful if you are trying to access old backups (backed up from another Mac) on a new or different Mac. (Sorry for the blurry images)
Hope this somehow helps someone else,

Hi there,
I have a macbook pro mid 2012 non retina display and i tried using an external display for it. I hooked it up and the screen blacked out and turned back on like normal and the computer itself was reading that the display was there. The only problem is that on the display itself there is no image of the macbook being displayed. im using a thunderbolt to vga connector and all the connection check out the only problem is the display. the display works on my other macbook that i have just fine i dont understand why it wouldnt work on this new one. Keep in mind i have had this computer for only 5 days.

Can Apple replace my macbook pro (mid 2012) retina's battery if I think that the battery health has gone bad/in need of and renewal???
I've had my Macbook for about 11 months now and i use it every day; its gone though about 420 cycles of charging and using the power, and i noticed the battrey preformance has decreased (as expected). The problem isn't sevear yet but it would comfort me knowing that i could replace the battery in the near future
Please contact me or answer the question if you know anything about this!Exitio\'s Apple wrote:

No only if they think under warranty/AppleCare, but your likely able to pay for a new battery if they have them, which they might not yet since it's such a new machine still.
BTW, I have a Early 2011 17" MBP, 27 months old, charges to 97% and has only 14 cycles.
