Safari doesn't open some pages

From the Safari menu bar, select

Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data

and confirm. Test.

From the Safari menu bar, select

Safari ▹ Preferences... ▹ Extensions

Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.

If you wish, you may be able to salvage the errant extension by uninstalling and reinstalling it. Its settings will revert to their defaults. If the extension still causes a problem, remove it permanently or refer to its developer for support.

Please read this whole message before doing anything.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.

Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.

One more test, if you don't mind. Boot in Recovery mode. In the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. While in Recovery, you'll have no access to your saved bookmarks or passwords, so make a note of those before you begin, if they're needed for the test.

Test. After testing, reboot as usual and post the results.

The cause of the problem is external to your computer.

Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.

I suggest you connect to a different network, such as a public hotspot or the hotspot created by a phone, and test.

Lot of good decent T/S help, but I have found of late that Safari in Mavericks will act badly. Same computer, same programs, same internet pages, same internet connection, no extensions or add ons for Safari.

Add to that mix Flash v12 (and you cannot go back since v11.9.900.170 has been declared a serious vulnerability version) and you have a real mess.

As an example - Angry Birds Star Wars will not load past the opening screen.

YET, using Firefox or Chrome, all is well.

Other problems in Safari, do not have same issues in Firefox or Chrome.

-- Same computer, same OS, no changes, no safe boot, and so on.

Could it be BECAUSE they are not inexoribly linked into the OS as Safari is?

I went through all T/S steps over my problem, nothing fixed it. That is when I tried Chrome and when all worked I had to scratch my head and mutter.... so Microsoft-like it hurts.

Since OS 10.7 one cannot reinstall Safari as a separate program. And when it fails, you have to wipe and reinstall the OS. A royal pain. And it should NOT be this way.

As a sugestion, maybe a corrupted user. Create a new temporary user with admin priviledges. Then try to use Safari as you want. If it works, then there are other steps to take. If not, it is easy enough to delete the new test user.

I have the same problem as TS.

MBPr late 2013, Mavericks, Safari + Chrome + Firefox. All latest updates are installed.

This problem started about a week ago.

Safari just does not open pages which it could earlier. Firefox has similar behaviour.

Even Chrome at first try sometimes say "page is not accessable", but after refresh it loads!

If Safari could load page and after that you try to refresh the page, you would get broken CSS and scripts (does not matter how much you would refresh the page after that).

But if you put cursor to address line and press Enter, page would load successfully.

It could be as simple as re-enabling Javascript, you should try that
