Delete all images from iPhone: there is no efficient method if you have iCloud Photos enabled.

There is a lot of incorrect web advice on iPhone image deletion. Some of it is dated, some of is recent regurgitation of old methods that no longer work. None of the articles I found differentiate between the behavior with iCloud Photos enabled or disabled.

If you have iCloud Photos enabled there is no efficient delete method from the iPhone. That’s because Apple doesn’t want us to think about photos being on a device. Devices are only temporary stores; the true home of a Photos is in iCloud. 

You can't use Aperture to delete after import. You also can’t use Image Capture (at least not from El Capitan). Aperture will offer the delete dialog but they will remain. In El Cap Image Capture does not show the delete option. I don’t believe Photos.app on Mac or iCloud will allow one to delete images that are ‘temporarily’ stored on a specific device — that really doesn’t fit Apple’s photo model. Again, the true home of a Photo is iCloud - device residence is a form of transient cache.

From the iPhone you can view the all photos album, scroll to bottom, select an image then slide up until all are selected, then delete. Apple doesn’t offer a delete all option because it knows iCloud Photos is confusing and, given half a chance, people will delete their entire photo library. Note this is only a first stage delete, you do this you have to go to recently deleted and empty that as well (“trash” equivalent).

With iCloud Photos disabled delete works from both Aperture and Image Capture.

I have experimented with using photo stream sharing from Aperture and iCloud Photos from Photos.app. It’s awkward and I periodically need to reenable photo streams in Aperture, but it has worked. I’ve decided it’s not worth the delete complexity though. For now I’ve turned off iCloud Photos and I’m back to old school wired transfer form phone to Aperture. I continue do iCloud photo stream sharing from Aperture and I subscribe to those on my iPhone and Aperture.

PS. With iOS 10.1.1 I saw some quite odd behavior after I disabled iCloud Photos on the iPhone. Even though Photos.app showed no images Image Capture showed many. I had to do a forced restart of the iPhone (deletes some caches) to clear out those ghost images.

iOS 10 bluetooth problems: repairing with Pioneer DEH-X6800BT

After the iOS 10 update I lost bluetooth connectivity to my Pioneer DEC-X6800BT car stereo. I tried the usual remedies.

I think the real fix was initiating connectivity from the iPhone side rather than the Pioneer side. The DEH-X6800BT was never able to find my i6, but the fine print in the manual said the phone might see if it if “Visible” was enabled. I confirmed “Visible” was “On” for the Pioneer, the iPhone saw it, the confirmation number appeared on the Pioneer, I accepted that … pairing resumed. Now I’ll see how well iOS 10 car park detection works (requires bluetooth connection between phone and stereo).

Other things I tried (maybe they helped?):

  • Usual wipe/delete connections on both sides.
  • Reset Pioneer back to factory mode (not in manual, had to Google, trick is to power off, then push the menu button and look for reset).
  • Reset network settings on iPhone
There are firmware updates for some Pioneer phones but not for the X6800BT. The stereo has an odd feature — if you cable connect an iPhone (any cable, don’t need their cable!) it will also Bluetooth pair transiently. Handy for phone of another family member.

Incidentally, I really dislike my DEH-X6800BT. Overloaded controls, too many poorly managed and weirdly distributed menus, processing pauses that make Siri unusable when car manages interaction, awful ideas like color shifting panel and “MixTrax” etc. The manual is seriously incomplete. Get something else.

Reset network on my iPhone also reset network on my El Capitan box

The joys of enabling keychain sync: “Reset network" on my iPhone also reset network on my El Capitan box.

Had to reenter the WiFi pw on my Macbook. Which reentered it on my iPhone.

It is possible to be too clever Apple.

Reusing old phones -- reset all before you put them in the storage.

We've accumulated several old iPhones - 4 and 4s. We find a use for them periodically -- as alarm clocks, media players and so on. 

Today I ran into a problem with this that I'd not considered. I went to reuse an old device with a restriction code -- and I couldn't because it was an old code we no longer use. It wasn't in my password store because it was obsolete.

Miraculously I remembered it. Two lessons learned:

  1. I can’t delete old passwords. I should know this. I ran into a similar problem years ago when Apple effectively made “mac.com” free again — and I no longer had the password I’d used when I stopped paying for it.
  2. You need to wipe phones before putting them in the bin. I was leaving them unwired as an extra backup during device transitions.

PS. Another reason to reset. If you restart an old phone it may register with iTunes and iCloud — and mess up iMessage addressing and iTunes device limits.
