Hello all, I will be ordering a new 13" base mbp this week after being in doubt to get the 15" for a long time. Figure I'd just get a iMac after that has been refreshed for the more serious stuff. Anyway, I have some questions: What would be the best way to transfer all my data (Currently have a regular macbook on 10.5.8)? The plan is to turn the MBP into my main machine and use the macbook i have now as a back-up or as a second machine when I am performing. I'd figure to 'copy' the hard-drive to the new MBP and then erase all the stuff on my regular macbook that I don't need anymore. I was thinking the advantage would be that this way it doesn't take so much time to transfer all my libraries, applications & plugins (itunes, iphoto, ableton, adobe CS etc.) But as my macbook is now 4 years old, will there be fragmentation on the new MBP disk if I just copy all the data over? If not, that would be great but then there is another thing. I am currently running 10.5.8. Would that pose any problems when copying the data from 10.5.8 to SL? Any advice on transferring my data would be greatly appreciated! Then another thing. I will get a 1TB external drive for storage and time machine. My current macbook has a 160gb HDD, the new MBP will have 250gb. Am I correct when saying that backing up both machines with time machine shouldn't take any more than around 400-450 gb max? And can I use the remaining space for other data or do I have to partition the disk for that to work? Thanks in advance!
