Apple Event: May 7th at 7 am PT
I am running Safari 6.2.8 under Mountain Lion on a MacBook Pro with the maximum amount of memory and RAM.
Safari has been moving very slow and crashing as well. I have cleared cache and cookies and restarted in safe mode, as well as shutting down and restarting. Things work well for an hour or a day and then it happens again. I have no extensions installed.
Does someone have some suggestions.
MacBook Pro, OS X Mountain Lion (10.8.5)
Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items. Quit/reopen Safari and test. You can also try try Safari/Reset Safari. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site. In Finder hold down the option/alt key while selecting the Go menu item. Select Library. Then Library./Caches/com.apple.Safari/Caches.db and move it to the trash.
Go to Safari Preferences/Extensions and turn all extensions off. Test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.
Safari Corruption See post by Linc Davis
I've tried all of these steps, singly and together, multiple times. I still am getting Safari slowdows and crashes.
Any other suggestions?
A clean reinstall is not possible. Although I have a recent backup and can make more, I have legacy applications which cannot be reinstalled from scratch.
Furthermore, the apple store installed my current mountain lion and I don't know if I can download it.
Might be a corrupt .plist.
Do a backup, preferably 2 backups on 2 separate drives.
Quit the application.
In Finder hold down the option/alt key while selecting the Go menu item. Select Library. Then go to Preferences/com.apple.Safari.plist. Move the .plist to your desktop.
Restart the computer, open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer ones.
If you want to make your user library permanently visible, run the below command in Applications/Utilities/Terminal.
chflags nohidden ~/Library/
I've tried the new solution, as well as the previous suggestions on multiple occasions, but Safari keeps crashing.
Try a restart.
Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.
