New iMac? Migrate Your Data EASILY.

Technology is designed to make our lives simpler. That's what it is for.

However, we've come to expect that certain tasks get MORE complicated as technology advances. Especially when it comes to computing, we have come to expect that more tech = more complications. 

I'm happy to report that migrating data from one Mac to another is not one of those complicated tasks.
First, some background. 

We recently upgraded from our 2009 21" iMac, to a brand-new 27" 5K iMac. 

But before we can take the old iMac out of service, we need to ensure that we migrate every piece of critical data. 

In the past, that was an arduous process.

I would usually remove the hard drive from the old PC, attach it to the new PC via USB or in an empty drive bay, and move files and folders one by one. 

In a typical Mac setup, that means moving your Photos Library, iTunes Librar(ies), and any loose documents and data. 

However... if you use iCloud like we do, your entire "migration" process may largely be complete!

IF you have backed up our iTunes and Photos libraries to iCloud, you'll be able to access your music and Photos from the moment you set up your new Mac. 

This was a pleasant surprise. 

However... we also want local storage of those libraries. (Photos has to be stored locally on the iMac - no matter how much we'd prefer it to be on the NAS. iTunes, it appears, can be run off a NAS with no issues.) 

SO - we need to do the following:

  • Ensure that every photo in our possession has made it into the iCloud Photo Library. 
  • Store a local copy of the Photos Library to our iMac.  
  • Verify that NEW imports of photos also get backed up to iCloud

  • Verify that all media is present in iTunes in the Cloud
  • Download a local copy of the iTunes library to the NAS
  • Verify that NEW imports of music to go the NAS iTunes Library 

  • Identify all remaining files with user-created data on our iMac
  • Assess all documents to determine whether migration is needed
  • Move all selected files and folders to the new iMac (or another suitable location)

Goodbye, Old Friend

BUT - before we move on - a brief reflection on our 2009 iMac. 
It was, without question, the greatest computer i have ever owned.  

For starters - longevity. 

From 1994 until 2009, I traded in my desktop PC every 3-4 years, minimum. And I usually spent the last year with a laggy PC that I couldn't stand. 

This iMac has been running for almost a decade, and is still going strong. 

It ran SEVEN versions of macOS -- Snow Leopard, Lion, Mountain Lion, Mavericks, Yosemite, El Capitan and Sierra -- with no issues. 

(It will get  upgraded to High Sierra as soon as this migration is complete.)

It even LOOKS new. From the front, the 2009 iMac has the same form-factor as the current gen. 

Unibody aluminum, with a mirror-black screen. This was the first iMac to have the "straight-edge" bottom border on the monitor. Magic Keyboard, Magic Mouse. 

So - thanks for your service, 2009 iMac. 

Enjoy your retirement years as an email-and-browser-only Mac at my dad's office. 

Our New Mac Setup

We were able to expand the RAM in our old iMac, but we had no easy way to get a larger internal hard drive. 

The old iMac had a 500 TB drive, and almost all of that was taken up by our Photos, iMovie and iTunes libraries. (Mostly iMovie.)

The new iMac has a 1 TB SSD, but we've learned our lesson. iTunes and iMovies libraries will NOT be stored on the iMac itself - that's what our QNAP NAS is for!

Photos is a different case. Apple does NOT recommend using a NAS to store your Photos library - and doesn't allow iCloud backup from that library. 

Migrating Photos and iTunes - Easy!

Assuming you've backed up your Photos library to iCloud, it's extremely easy to "migrate" to a new iMac... just log into iCloud, open Photos, and you'll see every photo in the library.

Problem solved.

For iTunes, we created a folder on the NAS called "iTunes", and then copied the entire iTunes Media folder to that location.

Then, we mounted the NAS iTunes folder on the new iMac, and pointed iTunes at the new library.

It worked!

Migrating iMovie Videos - and Loose Files - More Difficult!

Loose files weren't really "difficult".... unless you're like us, and kept files all over the place, and didn't use iCloud drive at all.

Use Finder--All My Files, and then Finder--Home to poke around your old computer, and identify where you might have stored data. And then, the easiest way to migrate it.... get a 2 TB iCloud account and start uploading.

If you're logged into iCloud on both iMacs, the files will be visible and downloadable from either.

As for video files.... this ultimately required some decision-making.

Eight years ago, I used this iMac to create a 30-minute home movie "show" for my parents' 60th birthday. I think I can do better today.

Ultimately, I decided that a clean break with iMovie was our best bet.

I kept a .MOV export of each of my finished iMovie projects, and copies of the underlying videos, which will be transferred to the NAS.

I didn't bother exporting and recreating the iMovie Projects themselves.... we'll be starting clean.

VHS and Super 8 transfers

A WHOLE lot of our old home movies are digital transfers from VHS.

Some of those are transfers from Super 8 to VHS, which 1) used to be a thing, and 2) reduced the picture resolution from "infinite" to "480i".

I have the original Super 8 film reels, which represent all of my family's home movies from 1976-ish until 1987 or so.

I've also got a box of old VHS tapes, which are our camcorder output from 1987 through the late 90s.

I'll get the Super 8 stuff re-digitized, at HD or Blu-Ray resolution.

The VHS stuff is what it is, but I recently picked up a JVC 9800-U SVHS player, so I can be assured of getting the absolute best possible output from those tapes.

From about 2002 onward, I was working with a Sony Digital Handycam, and then with a Flip camera 1080p, and finally, with iPhones.

Much of that recent video is stored in the Photos library. The older stuff goes to the NAS - and will be replaced with the new, better resolution captures.

As for the old iMac - that's going to be reformatted this afternoon - and then it's off to my dad's office, where it will probably put in another 10-year run.

Not All AirPort Extremes are Created Equal (UPDATED)

I'm looking for a used AirPort Extreme. In all the usual places - eBay, Craigslist.  I'll probably get one this week. Why? It's a long story.  A while back, I picked up an AirPort Express A1084 router on Craigslist, and found that it was incompatible with my AirPort Utility and wireless-n network, even though it looked *identical* to the current model of AirPort Express.  So, I wrote a post on this blog about the different types of AirPort Express routers, noting that if you're looking for used Airport Express routers to extend your AirPlay network, you'd better seek out model A1264. In the months that followed, Apple updated the AirPort Express again, changing the form factor (it looks like a little white AppleTV now), adding simultaneous dual-band support, and giving it model number A1392.  ASIDE: I'm not totally convinced that the form-factor change was an improvement. The A1264 plugged directly into the wall, which was incr

Review - WOW Ultra TV vs. DirecTV HR34 Genie

Here in the Chicago suburbs, we had two options for whole-home DVR services. We initially went with WOW Ultra TV, and after about 4 months, we switched to DirecTV's HR34 Genie system. (Neither Verizon FIOS nor AT&T UVerse were available in our area, so we can't review those. I haven't used Dish's Hopper, either. This is a straight compare/contrast review of WOW vs. DirecTV.) Both Ultra TV and Genie have their plusses and minuses. Both offer 1080p output, but that's primarily for the menus, as most TV content is provided at lower resolutions.  Both systems have a similar design architecture - a central hub, with multiple tuners and a large hard drive, recording and storing all TV shows, and distributing them to televisions around the house upon request.  Both systems also bring a number of "add-on" apps and have ways of accessing "on demand" content.  We've had each system for enough time to really put them through
