iTunes download error -8288

At least two users are updating their apps using iTunes 12.6.5.3, unlike all other users who cannot, and there are many on both Mac and Pc .

I tried everything suggested in several thread with no success.

All we have in common is that iTunes stopped to be able to finish an update since Feb 8 and on my side I didn't change anything on my computer(and so didn't others) beside the Apple Security Update. I'm able to download new apps but cannot update. At this point something must be wrong on Apple side or the two users who can update have some extra developer stuff or certificates we don't?!

turingtest2: do you think is this possible?

I am using iTunes 12.6.5.3 on PC. It was ok until Feb 9. No changes were made to security software, so it is no to blame.

I went to Purchased Items and clicked Download all. 8 of 100+ my apps were downloaded successfully.

Gatekeeper date : look for

com.apple.pkg.GatekeeperConfigData.16U1672.plist and

com.apple.pkg.GatekeeperConfigData.16U1672.bom

Both found in System/Library? Receipts

There are security system updates done automatically by Apple :

Look in System prefs App Store and I have “Install system data files and security updates” box checked.

BTW on my iPad and iPhone there are several apps to update that do not show up in the Updates section . To see those I have to search for each one and go in the App store where then they show that they need to be updated.

Definitely something is broken on the Apple side. Sign out and sign back in doesn't fix it

Updated info from Apple iTunes Support:

They say this is now a priority issue, there is to be a fix made up and sent out from Engineering. So we will see what they do next.

Thanks everyone for posting here by the way, I sent the rep to this string so I did not have a lot to explain

.

So I found a solution that was used for a different error code but worked for the very issue that I was experiencing as well the steps are indicated below for MAC users.

Learn what to do if you see error -45054 in the iTunes Store. If you don't see error -45054, follow the steps for your computer.

On your Mac

By

default, the built-in application firewall for macOS automatically

allows applications signed by Apple to receive incoming connections. If

you've adjusted the settings for your application firewall, you might

need to allow incoming connections. If the issue persists, reset the cache of accepted certificates:

• Click your desktop to make sure that you're in Finder.
• From the menu at the top of your computer screen, choose Go > Go to Folder.
• In the box, enter /var/db/crls/.
• Click Go.
• Drag the files labeled crlcache.db and ocspcache.db to the Trash.
• If prompted, enter your administrator password.
• Restart your computer, then try to connect to the iTunes Store, App Store, or Book Store.

For PC Users Try:

On your PC

• Check to see if you've turned on third-party security software
• or Windows Firewall. If you have, your settings might not let you
• connect to the iTunes Store, and you might need to change them.
• Check your Windows proxy server settings.
• If you see only a blank white screen with the words iTunes Store on it, you might have a conflict between software that monitors Internet traffic and Apple software.

Good luck folks

Thanks for your reply. I can't agree more. Now Apple has fixed this bug, but they are still not intended to get Appstore back in iTunes. It seems I should be grateful for they released a version with appstore, instead of blocking all older versions.

mojavenin içine tek başına kuramazsın demek şu anlama mı geliyor;

1-) mojavenin içine itunes 12.6.5.3 dmg dosyası olarak açıp yükleyemezsin demek mi?

eğer öyle ise kurulu olan itunes 12.6.5.3.app dosyasını alıp kopyala yapıştır yap diyorsun sanırım. ** akşam ** işle uğraşacağım.

memleket neresi?

I have to concur with you. It does seem like apple is blocking iTunes 12.6.5 ( listed by Apple as the Enterprise version) https://support.apple.com/en-us/HT208079

artoftrail, This same issue started at the same time on Windows PCs as well. I don't think it's a Mac Security update causing this. For all the reports I read this started on the even of 2/7-2/9.
