I currently have a 2008 2.66 intel core duo IMac, that has 640gb of hard drive....of which only 15gb is remaining!!!. ( which may account for poor performance) I have a 2 a 2TB time capsule ( which in time machine reads as 657 gb of 2 TB available....so am assuming I have used up 1.4g?) Whilst I have been waiting for a new Mac mini to be launched ( for home theatre use as a media server), and then seeing if the Mac mini gets thunderbolt 2... And if so, would iMac follow suit...I would finally update IMac as we'll. My big challenge now is how do I free up enough space on my 2008 Imac so that it can at least function normally as a family computer, and ensure I have all the movies, pictures, files etc saved in a safe place so that I can then transfer to new machine when it arrives...and ideally also keep as an offsite backup drive. I am not sure if I delete files from hard drive...whether these will eventually disappear from my time capsule.....and / or if I can save separately on time capsule ( tho clearly don't have too much space their either) Is there a better option of buying a future proof external hard drive ( any tips welcome), and then copying all content over.....and can I then reset my 2008 iMac for family use and transfer files to new iMac when I get it..( or would you recommend to keep as little on iMac as possible and use external drives / NAS as a better strategy for new iMac as well? I'm sure I am not the first to come across this conundrum, and would very much appreciate all advice. Thanks.
