I have not posted for some time, but now need some advice! My ancient iMac (c2005) is beyond updating & I am expecting to buy a MacBook (12" Air?) this year. In the meantime I should like to be able to back up all the material on the IMac G5 onto an external disc from where it will be available to the new MacBook when I get it, & also my current iPad Air, preferably via wireless. Is this possible? I fancy WD or Seagate, is there a 'best'? I have found trying to 'get into' WDs site to ask for info tortuous in the extreme. Thanks in advance. Dennis. PS I am in UK.
