<p>I ran the Mavericks update today, putting me at 10.9.2 and now my Bitcoin-Qt stops responding after it notifies me that it is "verifying blocks". I am using it for ongoing research and am in a bad spot now. I realize I should have thought about the possible ramifications of running the update.</p>

<p>At any rate, is anyone able to get it to run? I've tried running it from the .dmg via the gui and via command line. I get the same results in both cases. As soon as it goes to verify blocks, it stops responding.</p>

Yes, it's running on my system, which is a 5 year old Macbook Pro running 10.9.2. I have 4gb ram and a 2.4ghz Core 2 Duo.

I did have problems however trying to sync the blockchain initially. I had a partial blockchain that I had on another computer, which I copied over. Normally in this case the computer reindexes the block files on disk, figures out where it is, and then picks up downloading from the last point.

However, I got behaviour very similar to what you're describing. It would go to "verifying blocks" and stay that way for a very long time.

In the end I fixed it by deleting all of my previous blockchain (I deleted everything but wallet.dat), and then let the app download the blockchain from the beginning. It took about 4 days, but in the end it works as expected.

Didn't really test it out much, but I don't think I saw the same thing on my 20gb Mac Pro, so I think the MacBook was just too resource constrained.

Also, the [new Bitcoin coming out](https://bitcointalk.org/index.php?topic=495683.0), Bitcoin 0.90, is available as a 64 bit app for Mac OSX, so this will likely help. I'm running 0.90 on my Windows machine and it's fine. Haven't put it on the Mac yet.
