So, I just bought a used MacBook online, as I was looking for a cheap little laptop to dink around with. I do like everything about the computer, except that it is incredibility slow and sluggish. It takes almost a minute to open Safari and switching screens between iTunes and Safari can take almost a minute as well Details: Manufacturer Refurbished MacBook Mac OS X 10.4 Tiger 1.83 GHz Dual Core 512 MB Ram 56 GB Hard drive There is 32 GB free on the hard drive, so I know its not a memory issue. Would it help to put in more RAM? If I upgraded to 2 or 4GB for ram, would it speed up a bit, or is it a processor problem? Lastly, Im obviously not very tech savy would fixing the problem be something Id be able to do by myself or do I need to bring it in somewhere? Thanks for the help!
