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?

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.

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 :: 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?

Aug 20, 2009

My primary concern is whether or not uMBP users will ever be able to switch the graphics cards without logging out every time? I remember hearing that it was a software issue, does that mean that it might be supported in Snow Leopard?

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 :: Freezing - Now Restarting?

Jun 21, 2010

My MBP has been freezing over the past few weeks. When the computer freezes, the mouse gets hypersensitive, then it will be unresponsive to everything. The screen then goes black. One of three things then happen. One, I manually shut the computer down by holding the power button. Two, same as one except I get a Kernel Panic text file on my desktop when it loads back up (this only has happened once), or three, the computer restarts itself. It once from while I was playing Call of Duty 4, and once right after I had quit it. However, I had SMC fan set high whenever I play it, my computer is on a cooling stand and there's an desktop fan right next to it blowing over and under it. Could overheating still be a problem?

My MBP is late 2008 refurb, 2.53ghz, 9600 w/ 512 vram, 5400 rmp hard drive, 4gb Apple ram. Freezing has happened under both 9600 and 9400 cards.

The 9600 and hard drive have both been replaced by Apple in the past few months due to other freezing issues (the 9600 was defective, but when it froze I would get screen artifacts and the mouse would still move neither of those things happen now).

MacBook Pro :: New 17'' MBP Makes Odd Sounds When Restarting

Sep 13, 2009

I bought a new 17 inch MBP tonight. When it started up, it made a very odd sound that was similar to a CD/DVD being processed or ejected.I thought maybe it was a one time thing, but since restarting it a few times, it's made the same sound each time.Is this normal? I've never heard it before. It's like there's a CD or DVD in there, but of course there isn't.

MacBook Pro :: It Has Been Running Slow And Not Restarting

Feb 16, 2012

A few days ago I had to shut down my macbook because it froze. When I tried to restart it, it would sit on the grey apple screen and then after a few minutes it would restart again, and again, never getting past that screen. I called apple support and they tried to help me do a few things, non of which would work. Then they said I needed to reinstall OS Leopard but I did not have the discs, so I am waiting on them to be shipped. However, the next day I turned my mac on, and it worked. Since then I have turned it off and it has not worked again, but after doing a pram reset it works. However, it is very slow, only the safari browser will work, I cannot empty the trash (among other things) and just now when I tried to download an article off the internet, it said my disc was full and I had to delete things in order to clear space. if just reinstalling OS Leopard or upgrading to Lion will help?

MacBook Pro :: It Won't Turn On And Disk Keeps Restarting

Mar 27, 2012

My MacBook Pro 15" (2010 i think) ran out of battery, switched off really abruptly. Now when I go to charge it, the light at the front flashes on but then turns straight off before repeating. It tries to boot, I can hear the disk begin to whirr but then it turns off abruptly and it keeps trying. I don't understand why it won't boot and why it cuts out during the boot-up! It literally stops booting after 1 second. I think it might be my harddisk being full? It only has 900mb free?

MacBook Pro :: Keeps Restarting Randomly In Middle Of Use

Apr 21, 2012

In the last week or so, my computer has been randomly acting up:It has restarted over a dozen times when I pressed the "esc" button to exit from full-screen viewing while I watch video.It has gone to the sign in [initial purpley wave] screen when I was in the middle of simply typing a document.It has rebooted on it's own when I tried to use any application I use regularly- such as Photobooth, etc.And just now, I had to manually press the on-off button to get the computer started because my mouse was frozen.Sounds like there is a ghost in the ol' machine.

MacBook :: It Keeps Shutting Down, Then Restarting, Endlessly?

Apr 21, 2012

For no apparent reason, my Mac shuts down and attempts to restart. This happens whether any programs are running or not, and regardless of whether I am even touching the computer. It has happened when I have been working, or in the other room. When it attempts to restart and fails, I have to hold down the power button, wait, then turn it ok again.  The restarts were only every few days but frequency had increased now to every few minutes! What can I do, and what could be the problem? I am out of warranty. 

Context is relevant: two months ago my old battery died, and the fan was ticking loudly and always on. Brought her to the Apple geniuses at the local store. They were to take my laptop for an hour to replace the fan and battery. When I came back in an hour, my hard drive, which I had installed myself a year ago but had had no problems till then, had inexplicably failed. They could not restart. I went home to pick up my backup drive. They restored my computer there in the store, and put in a new hard drive, gratis, along with the new fan, which I paid for. Something about their anxious behavior and how long all this took suggested something else went wrong, but I could not ascertain what, exactly. 

When I got home, everything seemed ok till my computer randomly shut down and restarted twice. This picked up in frequency over the past two months, and you know the rest of the story, except this: 

When I opened up my Mac, under the battery, my warranty sticker had been partially peeled off presumably by a Genius, and was sticking up. This was a month ago.  Yesterday I took out the hard drive and held a flashlight to the inside. There were little bits of glue-balls rolling around, which I picked out, and a random orange wire sticking up. One of the little rubber tracks that support the drive is missing, but this has been the case for a year, with no problem. The glue-balls and the wire, however, were new additions.
