Hi everyone. I plan on replacing my hard drive on my MacBook Pro. I found a few good online tutorials that I think should allow me to do it okay. I have a question about how the computer will act and be like after the install. Is it just like having a new computer in that all programs have to be reinstalled? I ask this because of the RAM part of the installation where I saw a guy removing it before getting to the hard drive. Honestly, I want all the potential trojan horse stuff, viruses, stuff I didn't mean to download, off my computer once and for all. Some of this stuff is on there because of looking at porn sites. Will all that stuff be gone after a new hard drive? RAM doesn't hold anything, right? Thank you in advance for the help.
