iTunes not acknowledging iMac's authorization

When I connected the iPhone to my iMac and launch iTunes for a backup and sync a window comes up stating "Some of the purchased items on the iPhone "###", including "###", could not be transferred..." insisting that this computer isn't authorized. It instructs me to get my butt over to iTunes store and authorize it. Well, of course, it most certainly IS authorized. But I went through the paces anyway and verified that it is indeed authorized. It goes on to list over a dozen apps that are thusly affected.

So...what? What gives do you suppose?

iMac, OS X Yosemite (10.10.3)

Judging by all the other recent posts about the Port 443 error and authorization troubles, I'd say there's something bigger going on. Apple status says all is well, so it must just be a bug with the latest update.

With Apple new Apps thinning, apps on your iPhone has only the resources for your iPhone and it will not sync to your Mac iTunes because those apps on your iPhone cannot be the master copies for other Apple devices (iPad, iPad mini, iPod touches, etc).

You have to use Mac iTunes to download the apps for safe keeping.

Um...wow...I'll get to that in a sec, ckuan, but just a quick word to Don Ayer above, I am not experiencing that Port 443 error business and I am able to log into and buy fro the Apple Store.

But..."Apps thinning"?...what on earth is that? And I'm not following what you're saying anyway, Are you saying I can't backup my iPhone apps in iTunes? As far as sharing across devices, I just purchased an app with my iPad and it just noticed it is also on my iPhone so I'm not getting my head around you statement.

I maintain that this is due to an authorization issue, which is being troublesome for a lot of people today. I don't see how this error could be attributed to app thinning.

Yours is totally different thing, don't throw everything in one pot.

FWIW, I do not have this authorisation issue with iOS 9.2 and OS X 10.11.2 El Capitan with iTunes 12.3.1.

Just updated my iPhone 6 and iPhone 6s Plus as well as my iPad 3rd generation.

That's some "deep in the weeds" stuff. I had never heard of this. Don't know if it applies to me necessarily since, as I said, the iTunes line scale showing what is taking how much space shows a sizable chunk being apps, again, as expected, but the list itself shows but two. That's a far cry from only keeping on board that which is used most often and moving the little used up to Apple's servers.

Note, it is always a better option to download/updates your apps using the Macs iTunes (safe keeping).

It is because the developers of those apps can pull it out of the App Store at anytime, so if you do not have it locally it's gone.

As for purchase using iPad, only the resources for that particular iPad were downloaded and if your iPhone have in automatic download configured, it will automatically download the resources for that particular iPhone.

Mac's iTunes can download/updates all the apps' resources for all Apple devices as master copies locally.

When you connect your iPads, iPhones, etc. and sync locally then only the resources for that device will be synced.

That is the reason, you cannot sync your iPhone apps back to Mac iTunes since the resources for iPads are missing.

Well, time was that such was not the case with this thinning nonsense. Ergo most of my apps--I not being an app-hog of any sort--were acquired some time back and last I looked I could do my manual backup to iTunes and that was that. What I mean by this is that it sounds to me that you're saying--correct me if I'm wrong--the "Backup" section of the iPhone "Summary" pane is useless. I can click on "Backup to this Computer" but it's a meaningless gesture?

When you do a device backup using Mac iTunes, the apps data will be backed up but not your apps.

Apps can be updated/downloaded from the iTunes App Store directly for local safe keeping see the previous post.

"Well, time was that such was not the case with this thinning nonsense"

It's not, for example, I have many Apple devices and since the storage on devices is limited, I'm glad the apps resources do not take up space that was meant only for the iPad and not also on my iPhone. BTW, I do not have to do anything on my part to get that functionality.

iTunes backups

From your Mac or PC, you can make a backup of your device in iTunes. Syncing your device with your computer isn't the same as making a backup.

An iTunes backup includes nearly all of your device's data and settings. An iTunes backup doesn't include:

Content from the iTunes and App Stores, or PDFs downloaded directly to iBooks (You can back up this content using Transfer Purchases in iTunes.)
Content synced from iTunes, like imported MP3s or CDs, videos, books, and photos
Photos already stored in the cloud, like My Photo Stream, and iCloud Photo Library
Touch ID settings
Apple Pay information and settings
Activity, Health, and Keychain data (To back up this content, you'll need to use Encrypted Backup in iTunes.)

Learn how to make backups in iTunes, how to find them on your Mac or PC, and how to delete backups you no longer need.
