Hide/Show folders on Mac OS Apple

After upgrading from lion to mountain lion WiFi has a problem, from the Mac automatically hibernate after the network, wake up automatically re-connect.

From the forum to see a lot of Mayyo also and I have encountered this problem. So Google took a turn and finally on the Apple forum

Turned to the answer and solved the problem.

The steps are simple:

1. Open Disk Utility, select the partition on the system, select "First Aid" tab on the right, then click

"Verify Disk Permissions". (depending on the partition size may take a few minutes or more, the SSD will be faster)

2. When the Verify is finished, select Repair Disk Permissions.

And then my Mac was cured.

Attach the thread address of the Apple discussion area with the answer on page 22:

Ps:

For automatic sleep disconnect, manual hibernation (click Sleep in the top left-hand corner of the apple icon drop-down menu) or it will break the net.
