Chromium For Mac Браузер

  



Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web. This site contains design documents, architecture overviews, testing information, and more to help you learn to build and work with the Chromium source code.The Chromium projects include Chromium and Chro. The Chromium projects include Chromium and Chromium OS, the open-source projects behind the Google Chrome browser and Google Chrome OS, respectively. This site houses the documentation and code related to the Chromium projects and is intended for developers interested in learning about and contributing to the open-source projects.

Chromium is Google’s open source web browser project. It differs from Chrome in that it’s not a full-blown web browser, but a platform onto which third-party developers can build their own code and create their own browser. Unfortunately, not all of those third-party developers are interested in creating a great browser and instead want to make malware that they can use to infiltrate your computer and steal data.

Everything you need to know about Chromium virus

There is no Chromium virus, as such. So, what is Chromium? It is a legitimate Google-founded project that is used as the basis for several web browsers, including Google’s own Chrome. The difference between Chrome and Chromium is that Chrome is the finished version of Google’s web browser, whereas Chromium is the framework on which it’s built. When Google updates Chrome, it uses the latest code from the open-source Chromium project and then adds features and add-ons of its own. Other well-known browsers that rely on Chromium include Opera and Vivaldi.

You can even download Chromium yourself and run it on your Mac. If you do, you’ll find it looks and feels a lot like Chrome. However, if you do, you’ll be downloading what’s know as a “raw build” that’s likely to be unstable and crash regularly. You shouldn’t run raw builds on a computer you use for work. In addition, Chromium doesn’t update itself automatically, like Chrome does. So you’ll have to manually check for updates or risk running and out of date version. And running an out of date version of Chromium could be a significant security risk.

There is another issue with downloading Chromium: you should only download it from Chromium.org. If you download it from anywhere else, you risk downloading and installing a version that has been maliciously altered to bundle malware. While most of the developer who build Chromium-based browsers are legitimate, there are some scammers who use it to plant adware and steal data. That’s why some people think of Chromium as a virus.

To avoid being infected with this malware, only download Chromium from the official download site. Or, better still, only download reputable browsers built on Chromium, rather than the source build itself.

If you have already downloaded a malicious version of Chromium, you can remove it using the steps below.

How to uninstall Chromium on your Mac

Removing a legitimate version of Chromium is very easy. You can just find it in your Applications folder, drag it to the Trash and empty it. That, however, won’t uninstall it completely. There may be other files located in folders such as:

/Library/LaunchAgents

~/Library/Application Support

The easiest way to uninstall Chromium completely is to use the Uninstaller tool in CleanMyMac X. It deletes not just Chromium but all its parts and pieces across the entire system. This is how it looks:

  1. Download and install CleanMyMac X — get a free edition here
  2. Choose Uninstaller.
  3. Find Chromium in the list of apps or search for it in the search box.
  4. Check the box next to it.
  5. Press Uninstall.

That will remove every trace of Chromium from your Mac.

If the version of Chromium you’ve installed contains malware, the process is a bit more complicated. But you can still do it following these steps.

In addition to removing the app itself, and any app that it was bundled with, you’ll also need to do the following:

1.Remove Chromium and any app that it was bundled with

1. Go to your Applications folder and look for the app you downloaded just before you noticed Chromium on your Mac.
2. Drag it to the Trash and empty it.
You might also try removing Chromium from your Library.
1.Click on Finder, then choose Go in the top menu
2.Choose Go to Folder...
Now paste in the following locations

/Library/LaunchAgents
~/Library/Application Support
/Library/LaunchDaemons

Open these folders and look for files that have been added recently — you can use Column view in the Finder and sort by Date Added to find them. If you find any suspicious recently added files, drag them to the Trash and empty it.

Delete the app from your Login items

Now, choose System Preferences from the Apple menu and select Users & Groups. Click on your username and then on Login Items. Look for any login items that look suspicious. If you see one, check the box next to it and press the “-“ button.

2. Reset your other browsers

Some malware resets the settings in your browsers and installs extensions, so that even if you don’t use the malicious version of Chromium, it might infect your other browsers. You need to go through each browser you use and reset it by following the processes described below.

Safari

  1. Launch Safari and go to the Safari menu, then choose Preferences.
  2. Click on the Extensions tab and look for any extensions that seem dubious.
  3. If you find one, click on it and choose Uninstall.
  4. Choose the Search tab next and if your default search engine has been altered, change it back to your preference.
  5. Now click on the General tab and change the homepage settings back to what they should be.

Chrome

  1. Launch Chrome and paste the following into the address bar: chrome://extensions
  2. Look for any extensions that you didn’t install or that shouldn’t be there.
  3. If you find one, select it and click Remove.
  4. Now paste this into the address bar: chrome://settings
  5. Scroll down the page until you see the Search section.
  6. Set the default search engine back to your preference.
  7. Go further down the page until you see “On startup” and set the home page to whatever you want it to be.

Firefox

  1. Launch Firefox and click on the three lines on the right of the address bar.
  2. Choose “Add-ons” and then Extensions.
  3. Look for any extensions you don’t recognize or that you didn’t deliberately install.
  4. If you find one, choose it and press Remove.
  5. Click on the three lines again and this time choose “Options.”
  6. Set your homepage back to the one you want it to be.
  7. Now, set your default search engine to your preference.

Chromium For Macbook

Once you’ve removed Chromium itself, along with the app it was bundled with and taken care of any rogue browser extensions and changes it’s made to your browser settings, you’re nearly there.

However, there is one further thing you should do. It’s likely that the malware placed cookies and cache files on your Mac. To get rid of the malware you need do a scan with an antivirus. And guess what? You can do it with the same app we've just used — CleanMyMac X. It has a Malware Removal tool that blocks hidden apps and 'backdoor viruses' operating on your Mac.

Download the app for free and see if it removes the virus.
When you install the tool, navigate to Malware Removal tab in the sidebar.

Chromium is not a virus. It’s not even malware. However, some scammers have used the source code to distribute malware by pretending to be a legitimate Chromium build. To avoid installing a malware version, you should only download Chromium from the official website. If you do install a malware version of Chromium, you can get rid of it by using the steps above. Although there are several steps, it’s not difficult, and even easier if you use CleanMyMac X for some of the steps.

Chromium (web Browser) For Mac

There are instructions for other platforms linked from the get the code page.

Instructions for Google Employees

Are you a Google employee? See go/building-chrome instead.

System requirements

  • A 64-bit Mac running 10.14+.

  • Xcode 11.2+

  • The OS X 10.15.1 SDK. Run

    to check whether you have it. Building with a newer SDK works too, but the releases currently use Xcode 11.2.1.

Install depot_tools

Clone the depot_tools repository:

Add depot_tools to the end of your PATH (you will probably want to put this in your ~/.bash_profile or ~/.zshrc). Assuming you cloned depot_tools to /path/to/depot_tools (note: you must use the absolute path or Python will not be able to find infra tools):

Get the code

Ensure that unicode filenames aren't mangled by HFS:

Create a chromium directory for the checkout and change to it (you can call this whatever you like and put it wherever you like, as long as the full path has no spaces):

Chromium For Mac

Run the fetch tool from depot_tools to check out the code and its dependencies.

If you don't need the full repo history, you can save time by using fetch --no-history chromium. You can call git fetch --unshallow to retrieve the full history later.

Expect the command to take 30 minutes on even a fast connection, and many hours on slower ones.

When fetch completes, it will have created a hidden .gclient file and a directory called src in the working directory. The remaining instructions assume you have switched to the src directory:

Optional: You can also install API keys if you want your build to talk to some Google services, but this is not necessary for most development and testing purposes.

Setting up the build

Chromium uses Ninja as its main build tool along with a tool called GN to generate .ninja files. You can create any number of build directories with different configurations. To create a build directory:

  • You only have to run this once for each new build directory, Ninja will update the build files as needed.
  • You can replace Default with another name, but it should be a subdirectory of out.
  • For other build arguments, including release settings, see GN build configuration. The default will be a debug component build matching the current host operating system and CPU.
  • For more info on GN, run gn help on the command line or read the quick start guide.

Faster builds

Full rebuilds are about the same speed in Debug and Release, but linking is a lot faster in Release builds.

Put

in your args.gn to do a release build.

Put

in your args.gn to build many small dylibs instead of a single large executable. This makes incremental builds much faster, at the cost of producing a binary that opens less quickly. Component builds work in both debug and release.

Put

in your args.gn to disable debug symbols altogether. This makes both full rebuilds and linking faster (at the cost of not getting symbolized backtraces in gdb).

CCache

You might also want to install ccache to speed up the build.

Build Chromium

Build Chromium (the “chrome” target) with Ninja using the command:

(autoninja is a wrapper that automatically provides optimal values for the arguments passed to ninja.)

You can get a list of all of the other build targets from GN by running gn ls out/Default from the command line. To compile one, pass the GN label to Ninja with no preceding “//” (so, for //chrome/test:unit_tests use autoninja -C out/Default chrome/test:unit_tests).

Run Chromium

Once it is built, you can simply run the browser:

Avoiding the “incoming network connections” dialog

Every time you start a new developer build of Chrome you get a system dialog asking “Do you want the application Chromium.app to accept incoming network connections?” - to avoid this, run with this command-line flag:

--disable-features=“MediaRouter”

Running test targets

You can run the tests in the same way. You can also limit which tests are run using the --gtest_filter arg, e.g.:

You can find out more about GoogleTest at its GitHub page.

Debugging

Good debugging tips can be found here. If you would like to debug in a graphical environment, rather than using lldb at the command line, that is possible without building in Xcode (see Debugging in Xcode).

Tips for printing variables from lldb prompt (both in Xcode or in terminal):

  • If uptr is a std::unique_ptr, the address it wraps is accessible as uptr.__ptr_.__value_.
  • To pretty-print base::string16, ensure you have a ~/.lldbinit file and add the following line into it (substitute {SRC} for your actual path to the root of Chromium's sources):

Update your checkout

To update an existing checkout, you can run

The first command updates the primary Chromium source repository and rebases any of your local branches on top of tip-of-tree (aka the Git branch origin/master). If you don't want to use this script, you can also just use git pull or other common Git commands to update the repo.

The second command syncs dependencies to the appropriate versions and re-runs hooks as needed.

Tips, tricks, and troubleshooting

Using Xcode-Ninja Hybrid

While using Xcode is unsupported, GN supports a hybrid approach of using Ninja for building, but Xcode for editing and driving compilation. Xcode is still slow, but it runs fairly well even with indexing enabled. Most people build in the Terminal and write code with a text editor, though.

With hybrid builds, compilation is still handled by Ninja, and can be run from the command line (e.g. autoninja -C out/gn chrome) or by choosing the chrome target in the hybrid project and choosing Build.

To use Xcode-Ninja Hybrid pass --ide=xcode to gn gen:

Open it:

You may run into a problem where http://YES is opened as a new tab every time you launch Chrome. To fix this, open the scheme editor for the Run scheme, choose the Options tab, and uncheck “Allow debugging when using document Versions Browser”. When this option is checked, Xcode adds --NSDocumentRevisionsDebugMode YES to the launch arguments, and the YES gets interpreted as a URL to open.

If you have problems building, join us in #chromium on irc.freenode.net and ask there. Be sure that the waterfall is green and the tree is open before checking out. This will increase your chances of success.

Improving performance of git status

Increase the vnode cache size

git status is used frequently to determine the status of your checkout. Due to the large number of files in Chromium‘s checkout, git status performance can be quite variable. Increasing the system’s vnode cache appears to help. By default, this command:

Outputs kern.maxvnodes: 263168 (263168 is 257 * 1024). To increase this setting:

Higher values may be appropriate if you routinely move between different Chromium checkouts. This setting will reset on reboot, the startup setting can be set in /etc/sysctl.conf:

Or edit the file directly.

Configure git to use an untracked cache

If git --version reports 2.8 or higher, try running

If the output ends with OK, then the following may also improve performance of git status:

If git --version reports 2.6 or higher, but below 2.8, you can instead run

Xcode license agreement

If you're getting the error

Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.

the Xcode license hasn't been accepted yet which (contrary to the message) any user can do by running:
