Safari freezes on startup Yosemite

Hi ..

A Safe Mode boot deletes some system caches that can help after an OS X upgrade.

Top left corner of your screen click the Apple  > Shut Down

After your Mac shuts down, wait 10 seconds, then press the power button.

Immediately after you hear the startup tone, hold down the Shift key. You should press the Shift key as soon as possible after you hear the startup tone, but not before.

Release the Shift key when you see the gray Apple logo and progress indicator.

Then click the Apple  top left in your screen. From the drop down menu click: Restart

Then try Safari.

If that doesn't help, it could be a third party plug-in that's causing Safari to crash.

Follow the instructions here.

Hi Carolyn,

Thanks for the response but that does not seem to help. The problem started immediately upon the Yosemite upgrade and I am not running any 3rd party plugins on my Safari. Any other ideas?

Thanks

Same story as mcoluccio88.

However, I did have a few plugins running. When I deactivated them Safari worked for 40 seconds instead of 10, but now it's back to where it was. Spinning after ten secs.

So I just tried this and it worked for me: (typing this on Safari now!!!)

Open a Finder window. From the Finder menu bar click Go > Go to Folder

Type or copy paste the following

~/Library/Caches/com.apple.Safari/Cache.db

Click Go then move the Cache.db file to the Trash.

Quit and relaunch Safari to test.

Please check for plugins regardless.

Open the Finder. From the Finder menu bar click Go > Go to Folder

Type or copy paste the following:

/Library/Internet Plug-Ins

Click Go.

What plug-ins do you see in the Internet Plug-Ins folder?

🙂

These are the plugins I see. I had to disable all plugins to get Safari to work. Any thoughts as to which is causing the issue?

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar at the top of the screen. Click the Clear Display icon in the toolbar. Then take one of the actions that you're having trouble with. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name, may appear in the log. Anonymize before posting.

Try running Disk Utility and choose repair disk permissions.

I think the OP may had his problem solved, but for me Safari still does not work after trying Carolyn Samit's suggestions.

A bit of the log that must have coincided with Safari going down is:

I was facing problems with apple+F for a while and since Yosemite update safari was crashing or wasn't able to show the windows/tabs.

I was able to use safari normally after a restart without extensions (shift pressed during start) → and finally found that the old Glims extension was installed on my machine. I removed glims and everything is now working well.

I have tried all these options but i still cannot run Safari. I get the spinning wheel of death. Any ideas would be appreciated, really annoying me now. Thank you

Sorry for my ugly english, i'm italian. In my case, the problem was iCloud Drive. Try to deselect Safari options in iCloud Drive preference panel.

In my case, the method described frantsessochap helped on my Macbook Air mid 2012. But on my Mac mini late 2012 Safari 8 in Yosemite works perfect without deselecting Safari in iCloud Drive preference after a restart without extensions (shift pressed during start). Maybe problem with freezing Safari in Yosemite is problem only for Macbook Air?
