System does not update...

[ilya56]

Thanks to all contributors, but the problem persists...
Is there any other suggestions? May be corrupted permissions?

Any answer to my previous question:
if I reinstall Yosemite from the bootable USB over the existing one, is it any difference when I simply run Yosemite (10.10.2) installer from inside the current OS X (also 10.10.2)? Cause the latter I've already tried (no success...)

If you have a bootable USB of Yosemite, boot from it, use Disk Utilities to completely erase the drive not run it over what you have, and reinstall.
You do have a backup right?

If you want, you can try repairing permissions but that is not the be all, end all of System repairs. Sometimes you just gotta start from scratch.

I'm not ready to loose all my apps and setup...
Is there an easier way other than erasing SSD?

Do you have a Time Machine backup? Then no problem, you wont lose anything.
If not, you need to make one.
Or, do what was suggested in post #10.

I have the old HDD and it is fully functional and bootable (I made a copy from it to SSD using CCC and did it before this problem occurred).

May be I could just copy some system files from there?
Can someone tell me which files to copy?

possible fix

I have run into this problem a few times already with my new Mac and Yosemite. I am currently having the same problem. It doesn't do the updates. Previously I have tried to install software and fail for no reason.

Use your disk utility and click on you main hard drive. Click the verify permissions button. And my guess is that you will find a lot of ACL found but not expected details. Let it run. After that click the repair permissions. See if that solves your problem.

I've done it already several times. Doesn't work for me.
I've even reinstalled 10.10.2 over 10.10.1...

App Store does work, but it doesn't install just system updates. I guess there are some corrupted files or settings which don't overwrite during system reinstallation...
