Safari 5.0 Crashes: Fixes

A number of users have reported that Safari 5.0 crashes (unexpectedly quits) randomly during regular use. The crashes may occur during page loading, when Safari starts up, when the Mac wakes up from sleep, or when a new page or tab is opened.

There are a number of potential fixes for this issue, including:

Delete cache folder Navigate to ~/Library/Caches (this is the Library folder inside your user folder), and drag the folder to the trash. Quit then relaunch Safari.

Reset Safari Although you’ll lose some potentially valuable stored data, this very simple procedure can resolve the crashing issue in some cases. Simply go to Safari > Reset Safari (in the Safari menu bar) and check all items.

Delete add-ons. Some plug-ins and add-ons may be incompatible with the new release of Safari, causing crashes.

In Safari, go to Safari > Preferences in the menu bar. Click the “Security” tab, then deselect “Enable plug-ins.” Restart Safari. If the slowness is gone, a plug-in may be to blame. Look in the folders ~/Library/Internet Plug-Ins and /Library/Internet Plug-Ins and remove the items. You can then re-enable plug-ins, and add the items back one by one, restarting Safari after each, to identify the problem plug-in.
Perform the same process for any items in the following folders:

  • /Library/Input Methods/
  • /Library/InputManagers/
  • ~/Library/Input Methods/
  • ~/Library/InputManagers/

CT Loader has also been known to cause crashes. Delete all of the following files, then restart your Mac and launch Safari.

  • /Library/Application Support/Conduit
  • /Library/InputManagers/CTLoader
  • /Library/Receipts/ctloader.pkg
  • /Library/Receipts/.pkg
  • /Library/Application Support/SIMBL/Plugins/CT2285220.bundle
  • ~/Library/Application Support/Conduit

Downgrade to Safari 4.0.5 As a last resort, you can downgrade to Safari 4.0.5 as described here.

    What is APE, where do I find it? I can’t get Safari 5 to open at all, it comes up in the menu bar but no page opens and if I choose new page, it immediately crashes. Help.

  2. says

    If you are reading this, please – do NOT waste your time with fixes. None worked for me, including the downgrade to Safari 4 which is doing the same thing now. I am using Firefox 3.6.4 with no issues. I can’t even access this page with Safari! How sad is that?

  3. says

    Tried the solutions listed above, still crashing.
    What happened to Apple? God damn Safari is just keep crashing over and over again. Gotta change back to Firefox.

  4. says

    I was able to reinstall 4.0.5 using time machine. Safari 5 was fine for a few week then started hanging and had to be forced quit every few minutes nothing worked to fit it.

    I find Safari 5 o.k. for most uses, but it refuses to display PDF documents. I find FF fine for most uses, but it’s buggy. Chrome has become my browser of choice. It’s fast, efficient, nonbuggy, and loaded with efficient google add-ons. Even my friends at the local Apple store have told me that they like it!

    Moment I took that CT loader off, every thing came back to normal. I stayed almost a year without safari launching. The instructions here are the best so far. Thanks you guyz save my life
