In many cases, startup issues after a significant system update can be resolved by simply booting in Safe Mode -- accomplished by holding down the Shift key while your Mac is starting up. A number of maintenance tasks are performed during the safe boot, and you might not need to perform any additional troubleshooting. Try a safe boot, then a normal restart first.

Failing the aforementioned, peruse our tutorial titled "Startup fails (particularly after a system or security update); solving." One of the solutions listed there -- including delete specific caches, rooting out problematic kernel extensions, repairing drive damage, and disconnecting external devices -- might prove successful.

Problems connecting Meanwhile, some users have lost wireless connectivity after the update.

"I've just updated and restarted to find airport useless! Now airport just attempts to connect and says that there was an error connecting. When I click 'ok' the signal level goes up to full and drops immediately."

If you're experiencing a similar issue, your first course of action should be to make sure that your cable/DSL modem or router is using the latest firmware. Go to your device manufacturer's site and seek out an update.

Note that you may need to login to your modem/router's configuration page and reset SSID and security settings in order to invoke the improvements. See this page for general instructions on doing so.

Bluetooth problems -- re-pair If you're experiencing Bluetooth device issues after the AirPort update, try shutting said devices off, then turning them back on and re-pairing.
