app store error "this item is being modified"

Next question: if you look at some of the posts on this thread, they are a week old! So why does Apple continue to sell OS 10.7 if it can't redeem the purchases from April 20? I bought mine on April 27.

Why not 1) halt sales or 2) adopt a different method?

Makes no sense. Borders on the unethical.

Great news guys, just tried again and it worked! Downloading 10.8 now! Good Luck!

Wow, well, I was honestly losing hope, but it's downloading on my computer now too. Hope it's resolved for everyone else here, as well.

Still really unimpressed with how Apple handled this. A little more transparency would have gone a long way.

As soon as I saw this I tried to redeem again, but no luck; same old message. I decided to restart my system and try again (something the Apple tech asked me to try) I felt like a crazy person thinking it would work but success! It redeemed! Now to head over to 'Purchases' to downlo..... wait, where's my OS X Mountain Lion?!

I tried searching the store, didn't see it. Restarted the App Store, nada. I finally managed to wander into my Account settings and there was this option to 'View Hidden Purchases'; yes please. Which takes me to page where I could 'unhide' OS X Mountain Lion (I don't remember hiding that).

Ta-da! it's in my 'Purchases' and currently downloading! Best of luck to the rest of you.

Lion is downloading for me too! Hurray, finally...now will they credit the people who have been impacted? I must have spent 2-3 hours on the phone over this issue and tried to download it at least a dozen times, pretty sure my time is worth at least the cost of the software!

Yup, same here! Managed to redeem the code, now Lion is downloading and showing in the list of bought items in Mac App Store.

Thank you for the feedback, guys

Success here, as well.

Considering how much trouble it was to get your new OS upgrade, you might want to back it up.

I'm told the installer removes itself after the installation is complete, so if you need to reinstall the OS in the future (like after a hard drive failure) you may need to download it again from the App Store. I'm a bit uneasy about that, right now.

So, if you want to make a physical install disc - USB or DVD, it's best to do that *BEFORE* you actually install the OS update.

I forgot to mention that my version of the OS 10.8.5 Mountain Lion DMG was a bit too big to fit on a single layer DVD, but it worked for me on a dual layer DVD (get a good one, like Verbatim). Flash drive is probably the better way to go.

Mine is downloading also. Thanks for the info about saving the download.

Mine also finally downloaded after a few more false starts.

Thanks Apple for sorting it - a bit more communication on threads like this would be helpful in future.

I'd love to know the answer to this as I'm in the same boat. They haven't even responded to my email yet, so I'm very happy to see all the comments. Will let you when

I would like to follow up with ...success!!

My code for Mountain Lion has been redeemed.

It is now downloading.

-Thanks Apple

Followup...although my code has been redeemed, and Mountain Lion available in my download list..

the first attempt to download failed.

Download success.

IInstallation success. Thank you Apple for sorting it out. Thank you even more for all the posts. A problem shared is a problem halved 🙂

Thanks Apple for:

Reversing my scroll wheel? ***?

Completely erasing ALL my mail rules in MAC MAIL - great thanks!

Making half my programs on the dock un-usable (grey cross through them cant open now)

Enlarging my font and icon size

This is just what I've found in the first 5 minutes. YAY APPLE
