MacBook Pro :: Automatic Or Manual Switching Between Video Cards?

Jul 19, 2009

If I launch an app to do some video editing, does the MBP automatically switch to the higher-end graphics card? Or do I have to manually switch from "better battery life" to "higher performance"?

OS X :: Switching Video Cards In 10.6?

Aug 21, 2009

Is this any better? I know in 10.5 to switch between video cards (on the laptops that come with two) you had to log out and log back in. I've heard Windows can do it on the fly.

OS X :: Mac Mini - Automatic Vs Manual Sleep

Sep 29, 2010

I'm having a strange problem with sleeping my Mac Mini. If i let the computer automatically sleep then the 2 external drives spin up and down continuously. If i sleep manually ( > Sleep) then no such problems occur. The drives spin down, and stay down. Any ideas as to why this happens and how to make automatic sleep replicate manual sleep? why are they not identical?

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 :: 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 :: 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 :: 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.

OS X V10.7 Lion :: Disable Automatic App Switching?

Jun 1, 2012

This problem happens when I'm working between several applications at a time.  I'm actively working in the current app when OSX automatically pulls me out and shows me something in a background app that suddenly requires attention, like a dialog box.  Quite often I open or save files while working on something else, ususally in fullscreen mode.  Moments later, I'm disruptively switched to a file that just opened in another application, or I'm told that something was saved, updated, installed, etc.  This automatic switch interrupts my typing or commands in the app I was currently engaging, and has become a major problem. 

Is there a way to keep OSX from pulling me out of my current application?

Safari :: Switching Tabs Causes An Automatic Tab Reload In It

May 12, 2012

I generally keep 20 or so tabs open in my safari window. A month or so back, suddenly, each time I click over to a diffent tab the tab reloads. How do I stop this? And is this problem making my computer (fan or hard drive?) wind up for long periods of time? Sounds like a little jet engine about to overload.

OS X :: MBP Screen - No Automatic Shutdown When Switching External Monitor?

Apr 13, 2010

here we are with SnowLeopard 10.6.x and it still has no automatic shutting off laptop screen (Macbook Pro) when hooking up external monitor????Why do i have to close the lid, let my laptop go to sleep, wake it up, re-enter password, have my internet shut down and re-activate and all other processes just to shut down my MBP screen when hooked up to my cinema display???Hell even Windows Vista/ 7 does it automatically when i tested it via Bootcamp, requiring no closing of the lid or halting any processes or the internet.

OS X V10.7 Lion :: Mission Control Automatic Desktop Switching?

Apr 29, 2012

I'm currently studying for the GRE, and here's my current setup. 

Desktop #1: general computing

Desktop #2: vocabulary

Desktop #3: verbal

Desktop #4: math  


1) I'll have a Chrome window open on #2 at a website to help me study vocabulary.  However, when I'm at #1 and I click the Chrome icon in the dock to open a new browser to check email, it automatically takes me to desktop #2.  While I can just check my email at #2, I want to keep that desktop exclusively for studying vocabulary.  Is there any way to make MC treat each desktop as a separate desktop and NOT jump between desktops? 

2) This seems to be a MS Office specific annoyance.  I'll have a excel document open on #1 and #2.  When I close the excel document on #1, MC automatically takes me to the document in #2, when I just wanted to close the #1 document and stay in #1.   

3) A different scenario of the previous annoyance.  There's an excel document open in #2 and I'm currently in #1.  When I open an excel document MC...

- takes me to the ALREADY opened document in #2

- opens the document I wanted, but places it in #1

so that I'm in the wrong space AND not even looking at the document I just opened.

As stated, specifically I want to run Sim City 4 on my Mac Book Pro

The game will run but its glitchy, and slow, and occasionally freezes. So I know there are for PC but I cant any for the mac.

Hardware :: Video Cards In MacBook Pro - Integrated Graphics?

Feb 14, 2010

I may have sold a PC user on buying a mac and she's interested in the MBP. I noticed that some models of the MPB have a "NVIDIA GeForce 9400M + 9600M GT with 512MB" while others have the "NVIDIA GeForce 9400M." Are either of these integrated graphics? And what is the advantage of the models with "NVIDIA GeForce 9400M + 9600M GT with 512MB?" That sounds to me like it has two video boards. Why would Apple do this? And is there a big difference in video processing power between the models with one video board and two?

MacBook Pro :: Video Card Not Switching?

MacBook Pro :: Switching Video From 9600 To 9400

Sep 2, 2009

I purchased a 15" Mac Book pro a little less than 1 year ago. Right after getting it I changed the video to the 9600 and haven't changed it since. I tried switching it back to the 9400 last night and only got a black screen. If I do a hard shutdown and restart the system comes back up on the 9600 and runs fine. If I try switching back to the 9400 the same thing happens again (black screen). Obviously the 9400 worked fine when the system was purchased but hasn't been used since then so I don't know at what point the problem initially started. From what I've read, there are problems with some of the NVIDIA chips but it normally affects the higher GPU because of heat, not the lower one.

MacBook Pro :: GfxCardStatus And Video Card Switching?

Jun 29, 2010

I was using the nvidia card, which is the higher performance. I had parallels running and it was "dependant" on the nVidia card. So even when I went to battery power, it stayed in nvidia.

I closed parallels (while on battery power) and it switched to Intel video, so that works. Then I plugged the power back in, and have been plugged in for hours, I even unplugged the power and plugged it back in (switch from A/C power to battery, and back to A/C power) but it just stays on Intel.

MacBook :: Way To Connect The Video And Sound Cards Of Macbook & Samsung?

Mar 9, 2009

I have a macbook and a Samsung 1080p flat screen I would like to connect both Video/Sound too.I purchased Apples VGA cable along with a HDMI cable. The video output works great, no complaints with the video. The issue that I have ran into is sound, I would like to watch videos or listen to music on my Samsung. So here's where I am at currently. I purchased a Griffin Auxiliary cable w/male connectors. I plugged the cable into the both macbook auxiliary ports (1 at a time) and the Samsung auxiliary port. I was never able to get any sound out of the TV.
Can this be done with the hardware I currently have? If not, what would I need to fix or purchase that would fix the sound issue?

Mac Pro :: Effect Of Two Video Cards

Mar 8, 2009

I have a Mac Pro and two video cards, and am upping the setup to a new Nehalem Mac Pro with the ATI 4780 card + NVidia GT120 card. For illustration purposes, I will use those two cards to frame my question, as we seem to be pretty familiar with their specs by now. My question is somewhat conceptual, and is difficult to explain, but I am counting on the MR collective intelligence to sort it out! I'll use a few scenarios to illustrate my point: Scenario 1: Heavy use of the 4870 card, using both outputs (two screens). Naturally, performance is better than using the GT120 card.

Scenario 2: Same heavy use, but this time one port from the 4870 is used, and one port from the GT120.

Scenario 3: Same heavy use, but both ports on the 4870 are used, and one port on the GT120 (three screens total)

Scenario 3: Same heavy use, but both ports on the GT120 are used, and one port on the 4870 (three screens total)

How do software applications deal with two video cards? Would running Aperture, FCP, gaming etc., degrade just one screen? Wouldn't the whole application have to slow down to accommodate the lesser card? Is there a "primary" card and a "secondary" card designation? I'm thinking of multiple monitor setups (three, for example) where a lesser card is necessary to drive the extra screen, but the application is using all three.

Mac Pro :: Multiple High End Video Cards?

Aug 24, 2010

Does anyone with a Mac Pro '08 and up run it with 2 high end cards? ATI 4870, 5870 and/or GTX 285 are the ones I'm thinking of.On my MP '09, I currently run a 20" off the GT 120 and the GTX 285 on a 24". I have another 24" coming in (the Apple LED), so it requires me to use the GT 120. For gaming purposes, I'm considering getting a 2nd high end card for the new 24" instead of letting the old 20" act as a slave on the GTX 285 (trying to minimize load on the gtx285, again for gaming).

Mac Pro :: Two Separate Video Cards Work?

Jun 24, 2008

I just got a third monitor and need another video card for my 08 MP. I really want to get the 3870 but here's the questions. How do two separate video cards work? Will the two monitors hooked up to the 3870 look good while the lone display on the 2600 look like crap? My background is mainly final cut pro, with a sprinkle of Color (with MXO and yes i know only one card will work) and motion. So should I just save my pennies and get the 2600? Will a 1080p panel and a 1680*1050 be too taxing on it

So what are the top AGP video cards? Either being a Mac or PC that I could flash with a Mac Rom. What are the better choices that I have? I used to use flashed PC cards of 9800 Pro for my G4s but figured there are better cards for the G5. I do prefer to get PC cards since they are cheaper and I can flash them.

Mac Pro :: Install Additional PCI Video Cards

Mar 5, 2010

I understand that the PCI-X slots are backwards compatible with PCI, correct? If so, can we install 2 additional PCI video cards? Or, can we use PCI-X video cards for Windows and somehow flash them with Mac drivers? Of course, there is the matter of budget: we have very little to work with. Would any of you have a spare video card that would work in this machine and be willing to donate it? I can email you an in-kind donation form you can use for tax purposes.

PowerPC :: Can Run Multiple Video Cards In A System

Oct 27, 2006

Right now I've got a dual-DVI PCI-X card that runs two LCD screens on my PowerMac (the 256MB variant that shipped with the 2.0 DC). However, I just recently purchased a 37" LG LCD to replace my aging tube TV and I'd like to output my Mac to the LG to watch movies, etc. And at the moment, I have to unplug one of my smaller LCD's and run a cable to the LG.
