I have a 2008 MBP ( I know it is a relic) running Lion 10.7.5. I am out of memory and I am in the process of trying to clean it out. It is not letting me do a back up as it will not recognize the drive I am using (G Drive purchased from Apple store) which I have already used once before to back it up. Ultimately I want my G drive to be on my router to serve as a network drive so I hooked it into that. So- 1. How do I find a drive on my wireless router? Or- 2. What do I have to do to get my MBP to recognize the drive so I can at least back it up before I start clearing things out? Thanks.
