MacBook Pro :: Not Switching To Discrete (AMD) Graphics

Jun 25, 2014

MPBr, 15", Early 2013 with dual graphics (Intel HD Graphics and AMD Radeon)

Running Maverics 10.9.3 

What is happening:

1. Machine doesn't switch to AMD graphics no matter whatever app is running. In activity monitor even if some apps say "Requires High Perf GPU", the graphics card being used is still "Integrated".

2. Connecting to an external display via thunderbolt or HDMI doesn't work (external display doesn't turn on) either as it required discrete graphics too.

3. After a reboot (at what time I believe machine tries to use discrete graphics card), the display is always blank. Even the Apple logo on back of lid is turned off. Only way to get the display back is to close the lid and open it after 10 ~ 15 seconds at which time it probably switch back to integrated and comes alive. 

What I have tried:

1. Reset PRAM.
2. Reset SMC.
3. Tried gfxCardStatus [URL] to no avail. If I manually switch to discrete card, gfxCardStatus checkmark say it has switched, but it doesn't.
4. Tried booting into hardware diagnosis (pressing D while booting) but was unable to get the screen turned on to proceed.

MacBook Pro :: Way To Force Discrete Graphics On Or Off?

May 9, 2010

Apparently there's a utility called gfxCardStatus that shows you if your 2010 i5/i7 MBP is using integrated graphics or discrete graphics and now allows you to switch between them at will.The feature is experimental, as the site stresses, but it seems stable enough if you only wish to use it once in a while as I did. (I tested a game that didn't trigger the discrete graphics with the discrete graphics forced on) If you can't wait for Apple to get their game on I suggest using it.

MacBook Pro :: Stop Use Of Discrete Graphics?

Jun 26, 2012

I researched on the internet on how to stop the discrete graphics from unnecessarily being switched into use.

From this site [url]... i found that if i typed in the key in the info.plist in the package contents of the application, the application would stop switching the discrete graphics on.

MacBook Pro :: 13" MBP Update With Discrete Graphics?

Sep 19, 2009

What's the likelihood that Apple could update the 13" Pro with a more powerful discrete graphics card like the 9800 GT or 260M GTX? That would enough for me to buy the 13" MBP!

Mac Mini :: Discrete Graphics Cards - How To Know About It

Apr 16, 2007

why can't we have discrete graphics inside the mac mini? Two reasons. There isn't any space, and there's no way to connect it. To the first we could always mount the card outside the enclosure - I'm sure many of us here are able and willing to sacrifice the time needed to make that look pretty (or even the good looks) in order to get some better frame rates.

NVIDIA GeForce 8800 GS
Late 2008 I think?

BTW, the reason I am asking is because I am interested in this new Steam software that Valve is putting out and I want to know how well my Mac will do with the games.

Why Does MacBook Pro Have Graphics Switching

Apr 10, 2012

I was looking through tech specs of the 15 and 17 inch macbook pros and comparing them to iMacs, so i was wondering why they did that? Is the graphics better on the macbook pro?

MacBook Pro :: Graphics Switching In Windows?

Sep 7, 2010

The title is pretty simple, and self explanatory. Will the HD Graphics/330M combo, or the 9400M/9600M GT ever be able to switch back and forth in Windows? And regardless of if it's possible, what is the limitation, drivers, other software, or a physical hardware limitation? It would be a nice way to get more battery life out of Bootcamp.

MacBook Pro :: Graphics Card Not Switching?

Feb 5, 2012

I have a MacBook Pro 15" 2.66 GHz Intel Core i7 (Mid-2010). I have auto graphics  switching turned on in the Energy Saver prefs. But it never switches. It stays on the nVidia card all the time. 

I have tried switching to Text Edit, Mail, BBEdit, and other non-graphics intensive apps. It stays on nVidia. It stays on nVidia even when I unplug and use battery power. 

I can manually change it to Intel, and it works fine. When I change it back to auto switching, it stays on nVidia continuously.

Applications :: Does Turning On The Discrete Graphics Card Make Applications Faster?

May 27, 2010

Sorry for the incredibly stupid question, but I just got the gfxCardStatus application for my i5, and was wondering whether turning on the NVIDIA video card will make applications like Mail, Firefox, etc. faster?

I read something about OpenCL, but am not really sure whether it works for all applications.

I find that turning on the NVIDIA card, instead of using the integrated Intel one, makes my laptop hotter.

MacBook Pro :: Auto Graphics Switching - Delay?

Nov 4, 2010

Does anybody experience any delays with the auto graphics switching on the late 2010 MBPs? I mean serious delays? Mine seems to be very slow at making the switch. Say if I open a PDF that has a load of images in and start to scroll at high speed to scan the document, everything becomes very stuttery. Then, after a while (very random in how long it takes) everything starts to get smoother, when I assume the NVIDIA kicks in. I thought this was meant to be more-or-less instantaneous?

MacBook Pro :: Switching Graphics Cards Without Logout Possible?

MacBook Pro :: Graphics Switching Without Restarting Windowserver?

Apr 14, 2010

Obviously the new Macbook Pros do not require a reboot to switch between graphics cards while the previous generation, the one which had two graphics cards made by the same company, requires a login/logout. The case made for the necessity of this login/logout has been the need for the WindowServer process to be relaunched, and to overcome this, WindowServer would need to be rewritten. Obviously that didn't happen. Further, if random Nvidia insiders are to be believed, this wasn't done using Optimus technology by Nvidia, but rather by Apple... so. How do you suppose they pulled that off?

MacBook Pro :: Using External Displays And Graphics Switching?

Jun 7, 2010

I just plugged in my Cinema Display to my MBP for the first time, and for a while couldn't figure out why the heck the computer wasn't recognizing it (though maybe I'd gotten a bad MDP/DVI adaptor).

Then I'd noticed I'd set it via gfxCardStatus to use Intel graphics only. I released it to Dynamic -- and voila! Display recognized. Interestingly, it now also will not accept being set back to Intel only with the monitor connected.

MacBook Pro :: Why Does The Automatic Graphics Switching Turn Itself Back On

Jun 21, 2012

I have a late-2010 Macbook Pro 15" and have been having issues with gaming.  Specifically, the games will freeze the system requiring a reboot.  After reading further, I learned about the "Automatic Graphics Switching" mode under "Energy Saver" in the System Preferences screen.  Upon disabling this setting, and locking the preferences, the games are still freezing.   

I have not re-enabled this setting but when I check the settings again it is enabled.  Seemingly, the OS is changing the "Automatic Graphics Switching" on its own.

MacBook Pro :: How To Avoid Switching To Integrated Graphics Card

Jun 27, 2012

See the new Macbook Pro that I recently got has two graphics cards. One, the integrated, standard issue Intel HD4000 and the other one, a Nvidea GT650M. Personally, I was thrilled to learn this. However, my Macbook Pro seems to switch in between these two and I really don't want it to do that. I would rather just make the GT 650M the main graphics card and avoid using the integrated graphics.

MacBook Pro :: Automatic Graphics Chips Switching - Extended Battery Life

Apr 13, 2010

the new machines will switch between graphics chips. all very nice (at last), but my 15" MBP 2.8 doesn't and it's a real pain for me as I often go between apps than need the extra speed and then back to e.g. Word, and could really do with the extended battery life (I have the old style battery pack) any news if the older graphics systems can be worked to switch on the fly...i.e. without having to logout and shut down all the open apps, and work?

MacBook Pro :: Screen Flickers Black For Short Moment On Switching Graphics

May 9, 2010

I just got a new MBP i7, and whenever the graphics switch from the Nvidia 330m chip to the Intel chip, the screen "flickers" black for a short moment before reappearing. Can anyone with a new MBP comment on this behavior? It doesn't happen on the switch from Intel->Nvidia, just the other way around.

MacBook Pro :: Stop Automatic Graphics Switching Setting Automatically Reverting

Jun 25, 2012

Macbook Pro 15" Mid 2010

OS X 10.7.4 

I have a recurring problem where my screen (built in or external monitor/projector) will just go blank at random times. It is an unrecoverable situation and I have to do a hard power reset to get working again.

After testing several theories without success I struck upon one that showed promise. The blanking tended to occur when I was in Lion Fullscreen mode, or using a gesture to start expose - so I figured maybe it was a graphics switching issue.

So I went into System Preferences and disabled 'Automatic graphics switching'. I then ran trouble free for several days (I was typically crashing 1-2 times a day)

Then several days later it happened again and I thought I was back to square one. However, a colleague suggested I check the graphic switching setting to see if something had changed it back, and sure enough it was re-enabled.

Now I find myself in a constant battle with the system to keep disabling the 'Automatic graphics switrhing' in System Preferences.

I have tried setting it and locking it, but sooner or later it reverts. I need to know if it is possible to force it to stay disabled.

MacBook Pro :: Is 13" Going To Get Matte Screen/discrete Video?

Oct 3, 2009

The usual dilemma: to buy or to wait? Currently have a MacBook Alu and the LCD on this machine is simply horrible + I the glossy screen turned out to be pretty annoying (although I did like it initially).

I am thinking of getting a 15" with discrete graphics & matte screen (compared it side-by-side with a glossy @ AppleStore - the difference is HUGE)... but I could wait for a couple of months only if I knew that there was a 13" with a good screen/discrete graphics in development since I don't like the size of the 15" (weight is not an issue, it is mostly the ability to use it everywhere). I also compared the 13" MBP screen with a 15" (both glossy) and the 13" just sucks! Why can't they make the 13" a bit more expensive but give it a decent LCD? Even as an option? I have a Sony VAIO Z with a great matte 13" display, wish I could just transplant it into the the Mac

An ideal configuration for me would be a 13" with a decent matte screen and powerful graphics. But then, I'm a bit reluctant to wait as Apple may actually make matters worse by having worse graphics on new-gen MBP and perhaps no matte option whatsoever. I really don't care about the Arrandale vs Penryn, dual-core vs triple-core... whatever. The only part of the computer that I look @ all day long is the display, so it has to be a good one.

Lucidlogix have a real time GPU balancing solution that can render scenes in real time using BOTH the integrated sandybridge GPU and an ATI or NVidia GPU. If used in the next gen macbook pro it could make the macbook pro a real gaming machine. One little chip on the motherboard could change everything. Everyone email Steve Jobs.

Windows On Mac :: Force Windows To Use Embedded Video Instead Of Discrete?

Sep 15, 2009

Hopefully someone has run across how to do this. I have a newer unibody 17, looking to have windows use the embedded video card instead of the discrete for power reasons. I'm running windows 7 x64, everything runs great but the battery life is an hour or two less than OSX, and at least an hour of that is due to it not utilizing the embedded video.
