How to fix when Chrome won’t open

This solved a problem with two apps that would get blocked at startup (running macOS Sierra). One (AwakenHelper) was saying 'the identity of the developer cannot be confirmed.' The other was saying 'Tonido.app is damaged and can't be opened.' – Zade Mar 14 '17 at 8:03. After upgrading to macOS Catalina, some mac users feedback that some apps can’t be opened because Apple cannot check it for malicious software.A dialog box pops up, click 'OK' button and the application will close.

If you can’t open Mail on your Mac. If you try to open a version of the Mail app that can’t be used on your Mac, an alert message is displayed. Make sure the version of Mail you’re trying to open is located in the Applications folder. In the Finder, click Applications in the sidebar, then double-click Mail. Fingers cross, that’s the last of the ‘“Preview.app” is not open anymore’ messages. Check out this post if you need more help with crashing apps on your Mac. And let us know in the comments if you found these suggestions helpful! Do not get me wrong here. I don’t want to convince you to use apps from unidentified developers. However, if you ever want to do it, here are all the steps for running an application that ‘can’t be opened because it is from an unidentified developer’ on your Mac running MacOS.

1-It is possible that Chrome is already running. You may want to check if Chrome is already open. Here is how you can check this:

1. Press the Option, Command, and Esc (Escape) keys together or you can click Force Quit from the Apple menu (upper-left corner of your screen).
2. Do you see Google Chrome there in the list
3. If you do, select it and then click Force Quit, and try re-opening Chrome. if you do not see Google Chrome in the Force Quit window, then see the step below.

2-Restart your Mac. (see also: How To Use Spotlight On Your Mac)

3-If you do not see Google Chrome in the Force Quit menu (see tip#1), follow the steps below:

1. Go to the Finder of your Mac.
2. From the “Go” menu select “Go to Folder”
3. Enter this:
4. ~/Library/Application Support
5. And click Go
6. This will open a folder
7. Find the ‘Google’ named folder
8. Right click the folder and click Get Info
9. Click Sharing & Permissions to open the section
10. Click to Lock icon (bottom right corner) to unlock it. You need to be an admin and then enter your password.
11. Find the user who is having the Chrome opening problem and click its Privilege
12. Change Privilege from ‘Read Only’ to ‘Read & Write’.
13. Now click the Settings icon and select ‘Apply to enclosed items..’
14. Click Ok and try restarting the Chrome app.

4– If nothing helps you, you may want to try removing Google Chrome and then downloading and reinstalling. It is possible that your Google Chrome browser files may be corrupted and that is why it is now working. To uninstall Chrome, open Finder and click Applications. Then drag Google Chrome to the Trash. And then like the step number #3, select Finder and, from the Menu bar, click Go and then Go to Folder and enter ~/Library/Application Support/Google/Chrome and click Go. A new window will open. Select all the folders, and drag them to the Trash. This completely removes Google Chrome. Now you can go head and download and install again.

One of the most important new security features in the recently released macOS Catalina is that it’s much more difficult to run software that contains malware. Apple is now requiring that all software be submitted to them to be “notarized”, indicating that they have checked it for malicous activity.

Notarization is not foolproof, as something could slip by them, but it should significantly cut down on the recent growth of malware attacks on Mac.

Don’t worry though, this is not the same as App Store approval. Apps in the App Store often get rejected for violating a long list of Apple requirements. It’s their store so they control what goes onto it. The only thing they are checking for with notarization on Mac is that it’s not malicious.

However, suppose you need to run software that isn’t notarized. Perhaps it’s something you wrote yourself, it’s open source software that doesn’t have a large organized backing, or maybe it’s just old software that was released before Apple started this requirement.

Apple does have a way around this. They have said that on Mac they never have any intention of preventing you from running your own software. Just be extra careful before you do this. Make sure you trust the source of the software, since this feature is there to protect you.

When you start to run software like this just click the “Show in Finder” button (see above), then right-click (or hold control while you click) the app or installer in question and choose “Open”.

Now when the warning box comes back up you’ll have an option to “Open” and from now on the App will run without those extra steps.

Can't Open Apps

As developers take a little time to get on board with this new process, this will become less of an issue in the future. But right now you may run into this often.
