Macbook Pro Late 2012 Lagging when connected to external display (1GB Graphics Card)

I have a brand new Macbook Pro 15'' running 10.8.3 with 1GB NVIDIA GeForce GT 650M Graphics Card. I've been using the laptop conected to my Panasonic 720p TV for a while now and suddenly everything started lagging, the dock lagged, the lauchpad also. I have erased programs, music and everything left in my computer. Im running normally on 27% of the RAM memory (8gb) and have a capacity of 500+ GB left in the HDD. Please Advise...

Hi there Chiefinho,
You may find the troubleshooting steps toward the bottom of the article below helpful. Please keep in mind, diagnosing a recurring kernel panic can be difficult. If you would like to avoid this process, or do not know how to perform any of the following steps, consider bringing the Mac to a Genius at an Apple Store or an Apple Authorized Service Provider for assistance. Be sure to ask that, if the drive needs reformatting or replacing, they contact you about escalating your case to a special data recovery service. If you plan to visit an Apple Retail store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).

Switching MacBook Pro on without opening lid connected to external display

Hi all,
Simple question: I have external monitor, keyboard and mouse connected to my MacBook Pro and I wish to turn it on without having to open up my laptop.
I did find a resource over at Mac OS X Hints, but unlike other articles it is very lame. http://www.macosxhints.com/article.php?story=20080908013535674&query=keyboard. I do want a proper legit way of doing it!
For example, on PCs you can go in to your boot ram setup and make it so any key press can switch the PC on. Is this possible with my Mac Book Pro? I haven't been able to find a clean solution yet.
Any help would be appreciated!

Sorry, but it's not been possible to power up any Mac from turned-off state from an external device for a number of years (with the sole exception of the current Xserve). So you will have to open the screen on your MacBook, power it up, close the screen which will put the unit to sleep, then wake it from the external keyboard/mouse. Or attempt the trick on the site you posted for remotely pressing the power switch.
For this reason, most people who use their MacBook like you do just put it to sleep rather than powering it off.

HT4279 I have a Macbook Pro (late 2012) and I would like to connect it to 2 screens simultaneously (1 screen is a TV and can only take HDMI, the other is a larger computer screen and has both VGA and HDMI connections). How can I do this?

I have a Macbook Pro (late 2012) and I would like to connect it to 2 screens simultaneously (1 screen is a TV and can only take HDMI, the other is a larger computer screen and has both VGA and HDMI connections). How can I do this?

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.

I recently attempted to re-install Mountain Lion on my MacBook Pro late 2012 model and the internet recovery is failing.

I recently attempted to re-install Mountain Lion on my MacBook Pro late 2012 model and the internet recovery is failing. I have absolutely no clue what to do here. Any help is greatly appreciated. Thank you.
- Currently if I boot it up there is a flashing folder icon with a question mark in it. I am assuming this means there is no OS because I wiped the SSD and tried to reinstall Mountain Lion
- When I hold Command+R, it prompts me to Choose Network... the problem with this is the wifi constantly is disconnecting. The Retina 2012 does not have an ethernet port so i have considered buying the attachment then returning when done.
Once again Thank you in advance.
Best.

There is nothing to do if you don't have a reliable Internet connection unless you have a copy of the Mountain Lion installer application from when you first installed it.
Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

Using a macbook pro (late 2012) as primary desktop recommended?

I own a macbook pro Late 2012 edition and I am thinking about connecting it to an external monitor and using it as my primary desktop. Is this recommended? I am afraid that it will harm my macbook..especially the battery. Any insight would be appreciated.

If you use an external keyboard, USB or BT (as a desktop computer, you could use USB
and use a powered USB hub for printer, mouse, keyboard, etc and to import from devices
such as cameras, etc) and either get a stand to keep the MacBook Pro on edge out of
the way with the lid closed, or use it on a different stand to keep it up off the desk so air
can flow around it, with display lid open, for maximum cooling & extended/mirror desktop
use of the integrated display along with an external.
The battery should be used on occasion and not overly 'cycled' since it likely is one good
for up to 1,000 cycles of discharge & recharge; but never let it go completely flat or that
would damage its ability to carry a full charge. If I'm not mistaken that model is one with
an integrated or hidden battery behind the bottom plate, so it can't be removed and run;
but then if you did remove a laptop battery, it likely would cause the processor to reduce
speed and be less than optimal specification when you needed it for higher function tasks.
There are articles in Apple Support database on how to care for a portable Mac battery
and also some may be dated in that older models are suggested to be Calibrated on
occasion and the newest batteries (such as those in Retina models) are different. If you
have a MacBook/Pro with non-Retina display, check the support articles to see if that
model, with a built-in SuperDrive, could benefit form Calibration of the battery.

It is a good idea to get a spare power adapter of the correct model for your Mac.
I see there are some that are exact replacement on occasion at OWC macsales.
While in use as a desktop replacement, the computer may work better if you use
USB peripherals as the BlueTooth and other accessories would see less wear;
however that may be subject to a bias against using the built-in items so they
would not have a chance to wear out. Like the internal keyboard, for example.
A USB keyboard works in situations where the BlueTooth may not, and also
is easy to replace, where the built-in one is not easy, nor inexpensive.
Expect to replace the battery before the approximate cycle life is reached,
though it may be possible to exceed 1,000 cycles as noted by some who
have said they did; however you can't be sure how they arrived there. A
matter of use-patterns and careful consideration on what the portable does
in the course of a few years time could make a difference in battery life.
Yet some batteries can go bad without timely cycling and use. But do not
let the batteries go flat, recharge before they get too low so they don't see
any damaging discharge.
With the extended AppleCare plan, an option, the battery is covered for the
total duration of the extended plan. With a built-in battery, that is a fair deal
since the replacement, when covered, includes labor. Some models were
made in such a way as to allow a careful out-of-warranty battery replacement.
Check the online sources such as iFixit to see if after AppleCare, you would
even want to try to replace the internal battery. The AppleStore Genius could
do it for a slight fee over the cost of a replacement battery at that time.
With my (now older) Apple portable computers, I use a laptop stand, USB mouse
and keyboard, powered USB hub, wireless base station with Ethernet option,
both wired and wireless printing, & do not use an external display though I could.
That said, I use a Mini (Late 2005) G4 1.5GHz most of the time. My computers
stay on most of the time, and are allowed to sleep. They have some degree of
protection from power grid ill-effects through use of a power conditioning UPS
that can automatically switch when power goes up or down, and provides some
degree of run-time when the power goes Out. Not a whole bunch, though.
With an external display, and other accessories needed to use the Mac and to
shut it down when the power goes completely out, you may need to use more
than one UPS or uninterruptible power supply, but in some cases it has been
suggested in prior manufacturer publication, to not attach the UPS (whatever
brand) so they use the same wall socket; the excess power is expected to
surge or bypass the UPS and go to the Grounding wire. Be sure there is one.
Anyway, I have a few ideas and due to a few losses from trees hitting lines,
and outages lasting more than a week, with use of 'soft-power' generators,
my experience may vary as could my advice. Plan for the worst and hope...
Good luck & happy computing!

Best monitor for MacBook Pro (Late 2012)

After searching Apple's knowledge base (reference: Using 4K displays and Ultra HD TVs with Mac computers - Apple Support), it appears that MacBook Pro (Late 2012 model) does not support 4K monitors, correct?
If this is the case, what's the best monitor (resolution and pricepoint) I can get for this model? Should I just try to find an old refurbished 27" Thunderbolt Display?
My MBPr runs a 2.9Ghz Intel Core i7 w/8GB RAM and OS X v10.9.5.
Thanks,
Nicholas

A Dell ultra Sharp would be a good buy. Depending on what size you want:
http://www.amazon.com/Dell-UltraSharp-27-Inch-LED-Lit-Monitor/dp/B00P0EQD1Q
Otherwise, if you don't mind spending the money, and not worried about not using the monitor to its fullest this BENQ is an excellent monitor

I have a problem with using MacBook Pro as wifi router when connected to ethernet

I have a problem with using MacBook Pro as wifi router when connected to ethernet. The Airport icon changes to show a laptop inside, my iPad shows connected (I think) but Safari will not operate. I tried pinging my iPad, it seems to see the iPad, but no connection to Safari or to other apps such as Good on the iPad. I have read many posting and tried repeatedly via Sharing in Systems Preferences, but no luck. Suggestions to fix, or is this a Lion problem?

Usually this is a problem related to the domain name server address. If you open Network preferences, select your Ethernet port then click on the Advanced button then on the DNS tab. You will likely see an entry like 10.0.1.1 already listed. Click on the Add [-] button and enter 208.67.222.222 then click on the OK button and then on the Apply button. See if this helps.
if it does not help then repeat the above but with the Airport port.

Cannot change display resolution when connected to external display

On my 2.0GHz 13" MacBook, I have no problem with the display resolution when connecting to external display/projector when I am running in Mac OS, everything work perfectly! But things start to get messy when I am running in Windows VISTA 32 (installed within the Boot Camp 2.1). Whenever I connect to any external display/projector via a MiniDisplay-to-VGA cable, the resolutions on both my MacBook LCD and external display/projector drop to 640x480. And i am not able increase the resolution in the Display Settings. Does this mean that I have not installed the latest version of display drivers? Or is it that Apple did not provide the VISTA 32 drivers (in Boot Camp 2.1) that is compatible with the Mini Display port.

Cool!
I'm glad you have it fixed.

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!

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?

Right side of my LCD flickers, but not when connected to external display

The right side of my display flickers lines and inverted colors, but when it is connected to a display (with mirroring) there is no flicker. I have reset PRAM and SMC. Macbook Pro Mid 2012 2.3 GHz A1398.

I should note that when connected to an external display there is no flickering on either display.

No WIFI when connected to External Display

When I connect MBA to a Dell 2405FPW monitor, wifi gets a "connection timeout".
When I disconnect external display, wifi works - all this with the same wifi point.
I took MBA to the apple store, they connected the MBA to their displays and it works. This is very stressful since I cannot take the dell monitor to the apple store - Its where I work.
I also tested the MBA on a newer 24" dell monitor(At work) with same output. My only result was turninng to a less dimension monitor - works fine(again, all with the same wifi point). Is there a limitation when connecting MBA to external monitors - MBA? Again, very frustrating dealing with this issue. My previous MBP had no issues with this dell monitor. Any recommendations will be appreciated.

Alexander - I have a MBA 1.6 HDD and have been experiencing the same problem as you have. I connect via micro DVI to a 23" Apple Cinema Display and have been losing transmission speed or connection altogether with my Airport Extreme.
I have been reading the posts regarding this issue and found a link to this article on maximizing wireless connectivity with an external display and MBA: http://docs.info.apple.com/article.html?artnum=307295.
After reading the article and trying different settings, I found that my Airport was set to channel 11 and if I set it to 6 I stopped having connectivity issues and was able to work without incident. Give it a try - I hope it works for you.

Loss 3D graphics and can't connect to external display with NVIDIA card

I note this morning that the graphics in 3D mode of iWork (version 4.1 with system 10.6.8) no longer appears in all software suite. The 2D graphics are displayed perfectly. I also notice I can't connect an external display when I am on NVIDIA card but work well with Intel card.
The 3D graphics are printed but not displayed on the screen (it also appear inthe thumbnail). It seems to be a worry to display.
I posted two screen images showing the problem of 3D in Pages.
