I just bought a new MBP retina because my current MBP (2011/2012 or so) is locking up on me and I need a spare machine to use. Since my old one seems full of unknown glitches and software I don't use any more I think it's best to manually set up the new machine and reinstall everything. I'm willing to do this patiently but curious if there's a more selective way to transfer stuff- especially things like my email settings and folders. 2nd question- I have never wiped and started over on a MBP, but I would like to do this on my older one. It's still in great shape but locking up and super slow. I admit I haven't had the time to figure out why. Any suggestions about whether to tinker with it or just start over ? The problem is that it's functioning like an old windows PC- taking forever to do EVERYTHING and not responding in almost all apps except finder/moving and copying files. BTW. I suspect an encryption program I tried to use with dropbox called Sookasa has caused this. Does anyone have experience with this app ? I have uninstalled it for now but my system seems forever f-ed up ! Thanks for any/all help !
