safari opens but then becomes unresponsive

I just got a new iMac and have been getting to know it. Just today Safari has stopped working. It opens, and a dialog box flashes too quickly to see anything, and then it just becomes unresponsive. I cannot quit using the menus - only via force quit. I can click on the menu, but most options are greyed out. The browser window is completely unresponsive.


I have no idea what is going on. I am running BitDefender Shield, but I have never had any issue using it before.

iMac 27", macOS 10.14

You may  have adware/malware installed. Try downloading this program which was written by Thomas R, a long time poster. The program will search for malware/adware. The program will do the work for you which makes it easy. It may be necessary to run more than one scan. After running the scans, restart the computer.

Malwarebytes uninstall


I would uninstall Bitdefender. It tends to interfere with the computer's operation while providing minimal to no benefit unless you work with Windows files. Most long time posters recommend not using antivirus software or cleaning software such as CleanMyMac. They can adversely affect normal computer operation.


Bitdefender uninstall

Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply.

I had the same issue with Safari only on one of the accounts on the iMac. It was getting unresponsive and most of the items in the top menu for Safari get grayed out!

The Reason was the same as you mentioned, Safari was asking if it should keep the Data from other browser (in my case Google Chrome) and that pop-up message got disappeared so fast that before seeing this post I didn't even notice it!


To solve it I took these steps:


> I changed the default browser to Safari and restarted but this alone did not solve the problem for me.

> Then I opened a Finder Window and selected "Application" from left side. it opens a Finder page with all the applications.

> By dragging that Finder window I aligned the window in a way that when I double click on Safari's icon in that window and when the Safari gets open I can catch that "Don't Keep" Button without moving the cursor.

> Clicking on the "Don't Keep" Button, did the trick and it's working now!

You might need to try it several time to get the right position for the cursor. Also every time if you miss it, you need to Force Quit Safari and try again.

There should be a better way to do that but until figuring that out, this might help others.


P.S. There is a screenshot from a part of that pop-up message.

Did you try Malwarebytes? It may not help, but try running/posting the Etrecheck report in your normal account. If the log won’t post, try posting it in Pastebin and provide a link in a reply. After pasting the report in a PasteBin page, go to the top of the page, and copy the address in the URL bar. Paste that in a new reply.        Pastebin
