There was a very recent bug report about high CPU usage in 0.6.1 on OSX. If you're hit by the same problem, it's not coin generation that causes it, but a thread synchronisation bug.

Interesting; I will look into that when I get home.

# turn OFF coin generation

(Asked by: username_0 on 2012-05-08)

I just recently upgraded from Bitcoin client 0.3.? to 0.6.1-beta for Mac.

In the old version I had the option of generating coins; I don't see that option here. Activity Monitor shows Bitcoin-Qt consistently using >95% CPU. As I understand it, CPU mining is essentially useless, so I'd like to turn it off, but still have the option to receive coins if I'm paid by someone.

Is this possible?

As far as I know the option is off by default in the new versions. To make sure you can add a line

```
gen=0

```

to your [bitcoin.conf](https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File) file.

The SourceForge link currently on bitcoin.org points to the 0.6.2 version. Surgically insert ".2" to get a link to the fixed version:

<http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.6.2.2/>

Do not use this link if a newer release is available!
