MacBook Pro :: 2011 Overheats When Anything Is Plugged Into DisplayPort/Thunderbolt

Mar 22, 2012

I have an early 2011 MacBookPro 17" running Lion (OSX 10.7.3) 

Anytime I plug *anything* into the Thunderbolt port, the temperature jumps up by 15C-20C. 

To be specific, if I plug a "DisplayPort->HDMI adpater" in even if it's not connected to an actual display the temparature increases. 

SMC reset and EFI updates don't seem to help resolve the problem.  some users have reported that "InsomniaT" is sometimes the cause of the problem, however I don't have this sofware installed.

MacBook Air :: Using DisplayPort (for Monitor) And Thunderbolt At Same Time?

Jun 21, 2012

I have a mid 2011 MacBook Air 13 inch with a single Thunderbolt port.I have the Apple Mini DisplayPort to Dual-Link DVI Adapter cable which I am able to use to run a Dell 24 inch monitor - this cable connects to both the DisplayPort/Thunderbolt port and also a USB port on the Air.I want to be able to run this Dell monitor, and also run a Thunderbolt hard drive - one with 2 Thunderbolt ports.Is this possible?Can I connect the DisplayPort part of the cable to the pass-through Thunderbolt port on the hard drive, and then connect the hard drive to the Thunderbolt port on the Air?I would like to buy the Apple Thunderbolt display (which would solve this issue), but I suspect it will may refreshed soon. So I don't intend to get one until then.

MacBook Pro :: Mini DisplayPort To VGA Adapter Won't Work On Thunderbolt Port

Jul 3, 2012

I bought 2 new Macbook Pro 13' , 2.9 Ghz Intel Core i7, with 8 Go 1600Mhz DDR3,  Intel HD Graphics 4000 512 MB, Mac OS X Lion 10.7.4 (11E2617). 

I have connected a Mini DisplayPort to VGA Adapter in order to show presentations on different LCD projectors but  no image appear. 

The external monitor is detected but no image is shown. I have tried to change the frequencies: parts of the screen appears but no a correct image. I have the same symptoms with the 2 Macbook Pro. Using old Macbook Pro with the same Mini DisplayPort to VGA Adapter, the slides are showns normally. 

I make a test with a Mini DisplayPort to DVI Adapter and with a Mini DisplayPort to HDMI Adapter and everythings works correctly with both adapters.

OS X V10.7 Lion :: Why Can't Mid-2011 Macbook Air Detect Thunderbolt 1.2.1 Update

Jun 21, 2012

I'm using a 13 inches mid-2011 macbook air with OS X 10.7.4 on 12 June, I found the update of Thunderbolt 1.2 in the system update center and I patched it. Luckliy, this patch didn't kill my kernel as it did to many other machines. But I'm still a bit worried when I learned that this updates messed up a lot of users' machines. Now applle announces the newer version of thunderbolt 1.2.1 to correct what was wrong. But no matter how hard I try to check system updates, I don't have it. I know I could try to download it on the website, but is there any valid reason that I don't get this patch? Will install in creating new problems?

MacBook Pro :: Thunderbolt 2 Doesn't Work With Early 2011?

Dec 1, 2014

I've recently bought an external hard drive that works on Thunderbolt 2 (LaCie d2 3TB). When I connect the new drive to my Macbook Pro through the thunderbolt port, the drive isn't recognized. However, the drive works fine through a USB connection. I thought that Thunderbolt and Thunderbolt 2 are compatible, however this doesn't seem to be the case. Maybe it's because the OS X / driver / firmware version that I'm working on that is not updated? I work on an early 2011 Macbook Pro, OS X Snow Leopard.

MacBook Pro :: Late 2011 Lion Connected To Apple's Thunderbolt Display: Performance Very Low?

May 4, 2012

I have a MacBook Pro late 2011 with Lion installed. The Performance is less than I expected if compare with my old Macbook with Snow Leopard installed. Connect to Apple's Thunderbolt Display Performance goes doen to very, very, very, very slow.For Example to load a JPG in Preview it takes more than 30 seconds until 1 min to load. Same to start iWork like Pages or Keynote.Sometimes Safari freeze, loading images or loading plugins like flash animations. Generally Lion works with low performance and I wish Snow Leopard back. But my Mybook Pro late 2011 is not compatible to install Snow Leopard on it.

OS X Mavericks :: 10.9.4 - Thunderbolt Display For 6630M (Mac Mini Mid-2011) Broken

Jul 1, 2014

10.9.4 has failed to fix what was fine in 10.9.2 and broken starting with 10.9.3 -- a display (Dell U3011) connected to a Mac Mini mid-2011 via either a DisplayPort cable or dual-DVI adapter suffers from frequent loss of signal. The elsewhere-prescribed-juju of changing spaces, unplugging and replugging cables, ... works randomly and for short duration. 

HDMI connection works (producing non-native resolution on the U3011). 

This was filed as bug 17083693 and closed as a duplicate of 16197028.

Late 2011 MBP 15 Will Not Sleep When Plugged In / Display Goes Black When Opening Lid

Apr 11, 2012

This is an odd, intermittent problem that started about a month or two after purchasing my fall 2011 MBP 15 (i7 2.5, 16GB RAM). This problem started, went away on its own, and now it's back after about two months of being trouble free.When I close my computer, it doesn't go to sleep.The slit light on the right front of the computer does not go into its slow flash mode; however, it does light up solid, and theng it stays lit.When I open the lid, the computer wakes up immediately (it was never "sleeping" to begin with), but then after a second or two the screen fades to black.The screen can be brought back to life by pressing either of the brightness buttons on the keyboard.I took it to the Genius Bar, and of course I couldn't replicate the problem for them.When I got back home, I decided to test the computer plugged in, and that's when the problem came back.I don't know why it went away previously.So, in summary: The issue only occurs when the computer is plugged in.The sleep problem existed before I installed 3rd party RAM and Parallels 7, and they exist now after I have installed the RAM and new software.I use a wireless mouse, and the little dongle has no effect on the sleep issue - the computer will not sleep (when plugged in) either with or without the dongle in a USB port.The battery charges just fine.All of my software is up-to-date, and I'm running OS X 10.7.3I have checked for the Flashfake malware, and I do not have it.I am running Sophos Anti-virus; I have done a scan, and have found no threats.They flashed my PRAM and ran some tests at the Apple Store and everything passed.

Mac Pro :: Using Mini Displayport To DVI, HDMI Or Displayport?

Oct 28, 2009

I have an ATI Radeon 4870HD graphics card which has a Mini Displayport and a Dual-Link DVI port.

I'm connecting this to two Dell U2410 which each have a Displayport, HDMI ,DVI and VGA ports.

I can connect one of the monitors straight to the DVI port, but what should I do with the other? I can't find a Mini Displayport to Displayport adapter for sale in the UK. But there are Mini Displayport to HDMI adapters and Mini Displayport to DVI adapters available.

Also, would it be best to have both monitors on the same connection? If i go the HDMI route should I buy a DVI to HDMI adapter for the other port? Or have both on DVI? Will there be a visible difference between the monitors if they're not on the same type of connection?

MacBook Pro :: Won't Find Battery Life Info / Plugged Or Not Plugged

Oct 17, 2009

I use my MBP 15" (the new one), as my primary machine in my office. I sit by my best usually 10-12hrs a day working on it.

I am trying to figure out what is best to do, keep the AC plugged in or have it un-plugged and only plug it in when the battery is drained (or less then 50%)? I have tried different experiments, plugged in, not-plugged and time is about the same for life of the battery. The true question is, how is is best to do it for the health of the battery.

OS X :: MacBook Overheats In Sleep Mode?

Feb 16, 2007

This is the second time this has happened. I shut my macbook expecting it to go to sleep. I then put it in its booq sleeve and put it in my back pack. About 40 minutes late I pull it out of the case and it is WAY hot and the fan is going like crazy. I open it up and I cant do anything, I think because it is over heated. What is the deal?

MacBook Pro :: Overheats While Playing Game?

Dec 22, 2009

I just bought my computer 3 weeks ago. I installed windows in bootcamp and a few games on it.

When I play a game on it.within about 15mins.. my macbook pro (2.8GHz model) gets extremely hot. It's about 65 deg C (145 F).. I can hardly touch it just above the keyboard region. I'm guessing this is where the processor is.. The fans also kick in at full speed.

I do understand that the computer will get hot under heavy load.I'm just wondering if it is normal for the computer to get SO hot? Will it damage my computer in the long run? Should I go get it checked out at the apple store?

MacBook Pro :: Overheats When Playing Games?

Jan 5, 2010

My top-of-the-line Macbook Pro 15" locks up after about an hour (or less) of use when playing what is usually a Source Engine based game running in Windows on Bootcamp (booting into Windows). The screen goes black and the audio gets stuck in a loop and the game crashes. My only option is to hold down the power button.It seems of course to be caused by the GPU overheating.I can play a little longer when I have the laptop sitting on a packet of frozen spinach, sometimes peas or even chicken fillets.. but I don't need to say that this is unacceptable, especially when you're 3/4 a way through a L4D2 campaign.

MacBook Pro :: Overheats System - No Performance Or Visual Difference?

Jul 3, 2010

I got a program called "gfxCardStatus" that allows me to see which graphics card is being used and allows me to manually switch between them. I don't do anything graphically intensive in OS X (I only play games in bootcamp) but the nvidia card is being used most of the time and it makes my mbp hot and kills the time i can use the battery. I switched my MBP to only use the intel card in os x and have seen no performance or visual difference, but I was wondering if this is a bad idea?

MacBook Pro :: Fan Very Loud / Overheats When Playing Full Screen Video Or Games

Aug 22, 2014

Just purchased a MacBook Pro Retina, refurbished (because why not - the same product for a cheaper price) around a month ago. It's the 13 inch and is the model before the most recent one came out (4GB of RAM instead of 8GB - late 2013). From the very first day, playing a full-screen video on any site (be it YouTube, Facebook, etc) just makes the fan much louder than usual (so loud that you can almost hear it more over the video itself). Thought it may have been just a thing with Flash Player being buggy, but the problem has persisted for a while now. I'm not even pushing the CPU to any limits - literally playing a full-screen video on Facebook (not even in HD) makes the fan go crazy. 

Just last night I tried installing Borderlands 2 and it was the same thing - FPS rate was fine, no lag, just the fan was so loud that I actually got scared for my computer and turned it off. After closing the app and checking out the fan temperature, it was at 91c. 

Never happens when browsing/surfing or doing my usual work. 

Should I go give it back to Apple? The thing is I start university in less than a week (and hence will be traveling), so not sure if I can afford to give my laptop in to them for a long period of time (I know it should be free though since mine is a refurb item). May it just be an issue that is quickly repairable or is this worse?

MacBook Pro :: Get Mini DisplayPort To VGA?

Apr 17, 2010

I need to get a Mini DisplayPort to VGA adapter for my new MacBook Pro, but I know there are much cheaper ones about than the ones Apple sells.

Ideally, I'd like a single cable (rather than an adapter to plug a seperate VGA cable into) for a little less clutter on my desk, but if there's no decent solution I'll go with the adapter. I know most people recommend (URL), but I'm in the UK.
