I should start by saying hello and admitting that I am about as un-techincal as it's possible to get so you'll need to use very short words with me! I've been running an iMac with Lion for years and tried to migrate over to my new iMac with Mavericks. I wasn't able to do a Mac to Mac migration as my firewire cable won't fit into the new iMac, so I plugged in my Time Machine. I assumed this had been working just fine (had no problems with it over the years), but it seems that the last back up on it is dated July 2011, so now my new iMac looks like my old one did 2.5 yrs ago. I guess I can copy over the missing documents/photos etc from my second back up EHD, but the desktop doesn't "work" the way Mavericks is supposed to (scrolling etc). So I need your advice.....should I just copy over my missing files? And if so, will I need to re-install my (now very out of date) software on my new Mac? Or is it possible to un-install/delete the Time Machine migration I've just done and take the new Mac back to brand new/clean slate status? If so, please could some kind soul tell me how? Also, once I've sorted out the migration/clean slate business above, I'm planning to upgrade my 3 principal software packages (MS Office, Lightroom & Photoshop Elements) on home user licences - should I install my old versions first? I'm sorry if I'm using the wrong terminology but I would be very grateful for any assistance and hand holding you guys can offer. Thank you.
