My Problem

Downloaded a "free" VPN software package. The package took over control of my MAC-mini, could not even reload the OS from the install disk! Decided that more space on a new disk was the way to go.

My Fix

The replacement went smoothly. Just a little prying with a putty knife to get the case open and then eight screws to get the disk out. Excellent instructions ..

My Advice

Bluetooth and WiFi antenna wires tend to get disconnected. Make a note of which one is connected where -- the connections on my cpu did not match the on-line instructions.

Always work on a clean level surface with a hard floor (no carpets).
