I have a MacBook Pro 6,2, purchased in mid 2010, Processor 2.55, Memory 4 GB. Available: 420.12 GB; Capacity: 498.88 GB
Did not do a Time Machine backup. Have never done that. I am close to computer illiterate - sorry.
Don't know how to define slow other than it is much, much slower than before updating to 10.10.2. Takes forever to load an internet page.
When it freezes, I have to shut down by holding the power button down. That is the only thing I can do. Thanks for help. Please don't speak computer-eeze.
