If you use Google Chrome on your Mac, and chances are that you do, you must have noticed that it automatically updates itself. While this is definitely a good thing, partly because it saves you the trouble of updating yet another app, and partly (and this is important) because this means that you always have the latest security updates pushed to your browser. However, the problem is that if you want to disable automatic updates in Chrome, you simply can’t do it. There is absolutely no option in Google Chrome that will allow you to disable automatic updates for the browser. This is probably there so that users don’t disable updates, and end up making themselves vulnerable. But, if you really want to disable automatic updates for Google Chrome, you can follow the steps given below. Check Chrome’s Update Check Interval Google Chrome has a set interval at which it checks for any available updates.
Check Chrome’s Update Check Interval. Google Chrome has a set interval at which it checks for any available updates. If it finds one, the update is automatically downloaded, and installed.
If it finds one, the update is automatically downloaded, and installed. While checking the current value of the update check interval is not really necessary, it is a good idea to do this, so you can set it back to default if you want to. To check the current check interval, simply follow the steps below: 1.
Launch Terminal, and type “ defaults read com.google.Keystone.Agent checkInterval“. You will see a number in the next line.
This is the amount of time (in seconds) that Google waits before checking for an update. Usually, this value is set at 18000 seconds, or 5 hours. Disable Chrome Auto Updates Note: It is not recommended to disable automatic updates for Google Chrome, as this will leave you susceptible to potential security threats, that Google might patch in a later version. Only do this if you know what you’re doing. Also, it is recommended to manually update Google Chrome every now and then, just to be on the safer side. I will tell you how you can manually check for updates at the end of this article. All it takes is one command on the Terminal, and Chrome automatic updates will get disabled on a Mac.

If you’re sure that you want to disable automatic updates for Google Chrome on your Mac, just launch Terminal, and type the command “ defaults write com.google.Keystone.Agent checkInterval 0“. Setting the checkInterval to 0 basically makes Google Chrome not check for updates at all. This means that unless you check manually, Google Chrome will not update.
Manually Update Google Chrome If you have disabled automatic updates for Google Chrome, I would definitely suggest that you still manually run the updater in order to keep the version updated. To manually run the updater, simply follow the steps below: 1. Launch Finder, and press “ command + shift + G“. Or, you can click on “ Go - Go to Folder“. Here, type “ /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/” and hit Enter. Note: If that location doesn’t have anything, go to “/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/”, instead. Here, double click on “ CheckForUpdatesNow.command“.
This will launch the Terminal, and will check for updates. Once the process is done, you will see a message saying “ Process Completed“. You have successfully checked for any available updates. If any updates are available, they get installed on their own, and all you need to do is run the “CheckForUpdatesNow.command” program. Re-Enable Automatic Updates If you decide that automatic updates were probably better for you, you can always set them up again. All you need to do, is launch the Terminal, and type “ defaults write com.google.Keystone.Agent checkInterval 18000“. This will set the update interval back to the default value that Google Chrome comes with.
You will need to restart Chrome for the changes to take effect. SEE ALSO: Enable or Disable Chrome Auto Updates So, now you know how you can enable, and disable Chrome automatic updates.
Feel free to play around with the settings, and change the update interval to any value you like (the maximum is 24 hours), to control the frequency at which Google Chrome checks for updates automatically. As always, if you have any issues with these methods, do let us know in the comments section below.

These features include:. Limitations Think of Device Mode as a of how your page looks and feels on a mobile device. With Device Mode you don't actually run your code on a mobile device.
You simulate the mobile user experience from your laptop or desktop. There are some aspects of mobile devices that DevTools will never be able to simulate. For example, the architecture of mobile CPUs is very different than the architecture of laptop or desktop CPUs. When in doubt, your best bet is to actually run your page on a mobile device.
Use to view, change, debug, and profile a page's code from your laptop or desktop while it actually runs on a mobile device. Simulate a mobile viewport Click Toggle Device Toolbar to open the UI that enables you to simulate a mobile viewport. The Device Toolbar By default the Device Toolbar opens in Responsive Viewport Mode. Responsive Viewport Mode Drag the handles to resize the viewport to whatever dimensions you need. Or, enter specific values in the width and height boxes. In Figure 2, the width is set to 628 and the height is set to 662.

Show media queries Click a breakpoint to change the viewport's width so that the breakpoint gets triggered. Click a breakpoint to change the viewport's width Set the device type Use the Device Type list to simulate a mobile device or desktop device.
The Device Type list The table below describes the differences between the options. Rendering method refers to whether Chrome renders the page as a mobile or desktop viewport.
Cursor icon refers to what type of cursor you see when you hover over the page. Events fired refers to whether the page fires touch or click events when you interact with the page. Option Rendering method Cursor icon Events fired Mobile Mobile Circle touch Mobile (no touch) Mobile Normal click Desktop Desktop Normal click Desktop (touch) Desktop Circle touch Mobile Device Viewport Mode To simulate the dimensions of a specific mobile device, select the device from the Device list.

Landscape orientation Note that the Rotate button disappears if your Device Toolbar is narrow.

Show device frame When simulating the dimensions of a specific mobile device like an iPhone 6, open More options and then select Show device frame to show the physical device frame around the viewport. Note: If you don't see a device frame for a particular device, it probably means that DevTools just doesn't have art for that specific option. Show device frame Figure 10.

The Throttle list Mid-tier mobile simulates fast 3G and throttles your CPU so that it is 4 times slower than normal. Low-end mobile simulates slow 3G and throttles your CPU 6 times slower than normal. Keep in mind that the throttling is relative to the normal capability of your laptop or desktop. Note that the Throttle list will be hidden if your Device Toolbar is narrow. The Device Toolbar Throttle the CPU only To throttle the CPU only and not the network, go to the Performance panel, click Capture Settings, and then select 4x slowdown or 6x slowdown from the CPU list.
