It seems that the problem with 2 apps not accepted is fixed for me, but I'm not sure which of my actions helped. Brief explanation of what I had before and what was done follows.
So, first thing to mention is that I replaced (upgraded) SSD in my MBP 13 Retina late-2013 with eBay purchased Apple SSD just in a few days before Yosemite came out. The SSD purchased had some Mavericks on it which I used to download Yosemite, then did an upgrade install (for the sake of upgrade of recovery partition), and than reparationed SSD and did a fresh install of Yosemite, where I ended up with the "Accept" issue we are discussing here...
Tried reinstalls from network several times, was swithing apple IDs, etc. - no luck.
Then what I did that was helpful:
1. created SD card with Yosemite install (was tired to wait for download) following the instructions on the internet meant for USB thumb - it worked for SD as well
2. Tried to perform SATA security erase of whole SSD without luck, then used Parted Magic to erase whole disk system structures (like GPT, EFI partition, etc.). Apple's disk utility is NOT doing that! The idea behind SSD erase was that maybe some IDs of another Mac was stored somewhere on my newly purchased SSD, which could lead to our issue
3. installed Yosemite from SD card, eliminating the need to provide Apple ID to download OS. Then does NOT provide my Apple ID during the whole installation.
4. After that I installed the only update available without signing in to App Store (its iTunes 12.0.1 as of now). And I was ignoring offer to turn on Auto Updates - was not pressing neither "Not Now" nor "Turn On"
5. rebooted
6. opened AppStore again, go to Purchases and signed in on this page (at last) to see the list of the purchases. One difference from previous attempts was that I put Apple ID in a case-sensitive manner. For instance, my Apple ID was registered long time ago as "John.Doe@somemail.com" and I used to put it as "john.doe@somemail.com", but on the last attempt I put it as originally created ("John.Doe@somemail.com")
Voila - it does not have that "Accept" anymore. Installing back my iMovie and iPhoto from AppStore now...
As the conclusion, most probable actions that solved the issue for me was either
- total cleanup of whole SSD, the thing cannot be done with Apple utility
- installation from local media (instead of internet install) withOUT providing my apple ID during the installation
- uppercase in my Apple ID that I used to ignore on all previous attempts
... or maybe Apple just fixed the issue while I was reinstalling that 🙂
please try this ideas one-by-one to find out which one did the trick. easiest to check is case sensitivity of Apple ID (if its applicable to you). then goes reinstall from local media w/o Apple ID. and the last one to try is clearing up your disk with external non-apple tools
