How Much Free Space?

I sync my iPhone with iTunes. I like to have a local backup. Occasionally I get a message like this:

iTunes. Updating phone OS 01

Yay! An update. Let’s click Download and Update.

iTunes. Updating phone OS 02

Oh. Let me have a closer look…

iTunes. Updating phone OS 03

I’ve 1.36 GB of free space. That’s greater than the 770 MB that’s required. Let me sync the phone and see how much free space there is afterwards.

iTunes. Updating phone OS 04

Wow. 3.30 GB. That should be enough for the sync.

iTunes. Updating phone OS 02

Hmm. Let’s check the iPhone itself.

Well, I guess this figure of 411 MB is the number that the update process is seeing, and no wonder it’s complaining. But, why is iTunes giving me such a large figure for free space? Shouldn’t it be querying the iPhone itself and getting the phone’s free space number?

It may be that my iPhone needs to be restored. But even so, iTunes calculation of free space is not the same as how the iPhone itself calculates it. Which one is right?

iTunes; iOS 9.3.5 (13G36); OS X El Capitan 10.11.6.



Why don’t GIFs play in Photos (iOS or OSX)? They can be saved into Photos from other apps, and played by opening the GIF in Safari or by sending it to yourself in Messages. Even Quick Look in the Finder can play GIFs.

And why on Earth is Preview the default app for opening GIFs on OSX? Why does Preview separate the GIF into multiple pages, each with a single frame from the GIF? Trying to manipulate those pages (even quickly run down each image) will cause Preview to choke and stutter. It can even save an edit to a GIFs, but not play a GIF. It also can’t load a set of images and create a GIF from those. Does not compute.

This is how Preview displays GIFs. Very useful.

Photos for iOS 9.3.3 (13G34); Photos (Mac OS X) 1.5 (370.42.0); Preview 8.1 (877.7).
