Safari 5.0.1 Crashes at Launch: Check Third-Party Add-Ons

A handful of users have reported that Safari 5.0.1 crashes upon launch.

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 com.apple.Safari 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

In addition, it appears that APE (Application Enhancer) add-ons may be to blame for at least a portion of the crashes. As such, you may need to temporarily uninstall the APE system completely. Here are the instructions for doing so, from the Unsanity website:

“Prior to version 2.0:

Click on APE Manager or Application Enhancer in System Preferences. Choose the Uninstall option under the Information tab.

Version 2.0 and newer:

Click on Application Enhancer in System Preferences. Click the “Troubleshooting…” button in the About tab. Click the “Uninstall Application Enhancer…” button and follow the instructions.

OR

Download the Application Enhancer installer from unsanity.com/haxies/ape run it and click uninstall.

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