Timemachine is easy to use, (much much nicer than anything we’ve got). DO a timemachine backup before *anything*. WD make a USB (and USB powered) 1T ‘Passport’ $89 JB HiFi I’ve not measured but my opinion is that you need 25% free. If you told me 50% i’d not argue. If (click n watch fails) Install Yosemite -> use timemachine Will install yosemite and restore your machine (almost) exactly as it was. Mail, passwords, you *may* need to enter the license key for some stuff eg MS Word Once you have a TM backup you can slash-n-burn to get 50% free, upgrade, restore. You can easily install to an external drive eg my mac mini runs on a 2G WD Passport and has another as timemachine (oh the 500G internal disk? sorta ignored). I cannot notice any degradation (but unix does do that LRU cache) James -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
