Hey forum, I am currently running an almost Snow Leopard (10.6.8) on a 5 year old MacBook (mid 2007) and it's not nearly the machine it used to be . I am planning on buying a new MBP/MBA based on what is or isn't released at WWDC. I hope to be running Mountain Lion on this machine. Could someone explain any possible cons of using Setup/Migration Assistant to transfer data to the new machine? I went through a customization phase on my current MB, so I have a lot of junk on it and I wouldn't be surprised if I have some sort of malware, since the performance is flat out terrible at times. Is there any chance that any of this may carry over to the new machine? If specific problems maybe troublesome, let me know and I will list a few problems I am having. Do licenses for software such as MS Office get transferred with Migration Assistant? I also have a time machine backup of my current MB. Also, would you recommend waiting for ML, or buying just before ML since Apple offered Lion to users who had bought a Mac just before Lion came out? Thanks and hopefully none of those questions are too noobish!
