Help with properly updating software on MacBook n iPhone 4
I'm finally updating to a new iphone 6 from an iphone 4 that has never had software upgrades due to fear of glitches I often hear about after software downloads. I do not want to lose my notes, pics, contacts, voice recordings, etc., from my iphone 4.
Also, need help for proper steps to update my 2010 MacBook which has not been updated for same reasons. My MacBook OSX version is 10.8.5, Safari is 6.0.5
iPhone 4 "version 6.1.3.
Also, i get this message when I sign in to my email account: "This version of Safari is no longer supported. Please upgrade to a supported browser"
My daughter updated her year old macbook and now is slow to turn on.
I also would like help in how to back up the information I do not want to lose stored on iphone 4. Do I need to upgrade software on MacBook first then back up phone then upgrade iphone 4? How do I transfer backed up info to new iphone 6 and not transfer glitches? Not sure I'm asking the right questions. Thank you for your assistance.
MacBook Pro (13-inch Mid 2010), Mac OS X (10.6.8), no software updates
