Q. Connected to Internet But Can’t Browse?

Ans : Try a Safeboot,a Safeboot will clear out cache files, repair file permissions. It can resolve lots of strange issues and you can browse again 🙂

Can we use safe mode to isolate issues with our Mac ? Yes,You can use safe mode to help resolve issues that might keep your Mac from completely starting up, or to isolate other issues related to your startup disk.

What is safe mode?

Safe mode (sometimes called safe boot) is a way to start up your Mac so that it performs certain checks and prevents some software from automatically loading or opening. Starting your Mac in safe mode does the following:

Verifies your startup disk and attempts to repair directory issues, if needed

Loads only required kernel extensions

Prevents Startup Items and Login Items from opening automatically

Disables user-installed fonts

Deletes font caches, kernel cache, and other system cache files

If your Mac has an issue that goes away when you start up in safe mode, you can use this information to isolate the cause.

Start up in safe mode :

To start up in safe mode:

Start or restart your Mac, then immediately press and hold the Shift key after you hear the startup tone. Release the Shift key when the Apple logo appears. Safe Boot appears on the Mac OS X startup screen.The white Apple logo appears on your display. If you don’t see the Apple logo, learn what to do.

Release the shift key when you see the login window. If your startup disk is encrypted with FileVault, you might be asked to log in twice: once to unlock the startup disk, and again to log in to the Finder.To leave safe mode, restart your Mac without pressing any keys during startup.

If an issue doesn’t happen when your Mac is started in safe mode, try restarting without pressing any keys.If the issue comes back, you might have incompatible login items.

If the issue doesn’t come back, it was probably caused by a cache or directory issue with your startup disk, which safe mode fixed.
