Installing gfxCardStatus will help you manually set the graphics card in use, so you don't have to deal with automated switching. In fact, I think it helps solve the issue because freezing is caused by problems with the automated switching. On the other hand if you want maximum performance all the time, then discrete only will make sure the most powerful GPU is fired up.įor most situations OS X does a decent job of managing power considerations, but if you want a little more control, gfxCardStatus will let you set up GPU power schemes to define which chip is used depending on power source. karohan said: I don't think the freezing is caused by gfxCardStatus. If you want to save as much battery power as possible, leaving it on integrated only will ensure that the power hungry discrete GPU doesn't fire up. A drop down menu provides you with three options: Integrated Only Discrete Only and Dynamic Switching, which is the system default that lets OS X decide which graphics card is required. Sitting up in your menu bar, gfxCardStatus shows you at a glance which card is currently active, but more than that, it actually allows you to manually switch between the GPUs. gfxCardStatus is an open-source menu bar application that keeps track of which graphics card your 2010 MacBook Pro is using at any given time, and allows you to switch between them manually. That's where gfxCardStatus comes to the rescue. It's often tricky to know which card is currently in use as the switch between the two is seamless. The dual-GPU can be managed automatically by the operating system, but gfxCardStatus enables you to force the switch and preserve battery life in particular situations.Some newer MacBook Pros have been packing dual graphics cards for a while now, with the ability to dynamically switch between them - integrated for battery life and discrete for performance. Unfortunately your mac is designed such that in order to use an external display, it has to use the discrete graphics card. Since being tipped in the comments section on one of our MacBook Pro articles, we've been keeping our eyes on a particular utility developed by independent OS X developer Cody Krieger called. To sum up, gfxCardStatus offers manual control over the GPU switching modes for MacBook Pro users. This useful utility displays a bar showing the status of your graphics cards, allowing you to quickly identify which card is not working, and enables you to quickly switch to. Also, you cannot switch to the Integrated Only mode if there are apps in the Dependencies list. GFXCard Status is an open-source utility for OS X that displays which graphics card is currently being used on MacBook Pro (and the older iMac) by monitoring a console. There are a couple of workarounds on the program's website's forum. Worth mentioning is that gfxCardStatus needs to be on the Dynamic Switching mode if you want to use an external display. due to a change in the OS, gfxcardstatus itself is now seen as requiring the discrete graphics card. The menu’s icon reveals, at a glance, which GPU is in use: i for integrated or d for discrete. Identify the applications that activate the more power hungry GPU The solution is gfxCardStatus, which runs as a systemwide menu. This way, you get to see if the Discrete Only mode is turned on and taking up resources without a good reason. Just navigate to the status bar menu and open the Dependencies lists. GfxCardStatus can also help you distinguish the applications that activate the more power hungry graphics card. Consequently, the Discrete Only preset enables the graphic card that needs more power. It is an open source application that works on Mac 10.6 and higher. If you opt to activate the Integrated Only mode, your MacBook Pro will go on and use the more battery-friendly graphics card. gfxCardStatus is a must-have app for MacBook Pro users, as it not only brings convenience in switching between installed GPU but also prevents quick battery drain by automatically switching to specified graphic card. In addition, you can also choose to activate the Dynamic Switching mode, which means that the built-in macOS controller takes over. If you force integrated graphics in GfxCardStatus, Mac OS X (up to Yosemite at least) doesn't allow you to use multiple monitors (even though the built in Iris Pro can do it). Note that the gfxCardStatus status bar icon changes depending on the currently active switching mode: i is for Integrated Only, and d represents the Discrete Only mode. Check which graphics card is active on your MacBook Pro If the system switches to one or another, you will receive alerts via the Notifications Center. GfxCardStatus resides in your status bar and provides details about the currently used GPU, together with the current power source: battery or AC. gfxCardStatus is a simple status bar menulet that enables you to manually control switching between the graphic cards. MacBook Pro models come with dual GPUs, and macOS a switching system that activates one or the other, depending on your needs.
