As you might know, there's finally a beta version available for Mac users. I though this thread would be good, so that Mac user like me can give feedback and report bug found in the beta, since there's no specific Mac forum/section.
To start the topic, I've found one problem.
Desciption of the problem: uTorrent will use 100% of the CPU, so the fan will turn on at full speed, even if there's no active torrents.
Operating System: Mac OS X 10.5.5
Platform: Mactel (Intel based Macintosh)
Let me know if you need further informations.

Moved to the Mac forum. To prevent this thread from becoming a conglomerate bug reporting thread (that's never a good thing), I've split the posts up.

I have the same issue. I just downloaded µTorrent from the beta page. When I started it up, it was using 100% CPU. I waited to see if it was some temporary thing, but CPU usage never went down.
As I'm on a laptop, I can't use uTorrent with all the fans running, so I hope this gets fixed soon.
Mac OS X 10.5.5 / 32-bit Intel (Core Duo).

Have you ever run the leaked builds? Does it still happen if you clear the preferences (delete /Users/username/Library/Preferences/com.bittorrent.µTorrent.plist and /Users/username/Library/Application Support/uTorrent)? Can you take a sample and post it? (Open Activity Monitor, select uTorrent and hit 'Sample')

Here is the sample from the activity monitor

Sample analysis of process 13637 written to file /dev/stdout

Something like that happened to me when I added my first torrent (about 1 gig). Now it's working fine. But was kinda scary (almost give up it)
Offline
@temporary: Does it still happen if you trash the preferences?
Offline
Removing the preference file and the directory in Application Support does not make this issue go away for me.
Notably, I have my Mac firewall configured so that I have to allow µTorrent to accept incoming connections. I got that dialog twice when I first started the program after downloading it. Could this have any effect on µTorrent's operation?
I also have PeerGuardian OS X installed and active.
Offline
I am having the same issue, and also have peerguardian active. I think it may have something to do with that.
Offline
The Mac firewall won't affect uTorrent. I've got the same setting for it.
But it's quite possible that Peerguardian can be doing something. I would recommend removing it and trying again.
Offline
Hi,
After removing PeerGuardian everything works fine.
But don't we need PeerGuardian?
Best Regards
Offline
You don't need PeerGuardian. The blocklists are maintained by someone who adds IP's based on personal grudges and refuses to remove them. utorrent.com has been blocked from the lists, as have major trackers.
Offline
Actually I do need PeerGuardian. I create custom block lists for intrusion attempts... it's quite easy and I don't want to sacrifice that. I'd rather stick with Transmission as my BT client if µTorrent won't work with PG.
Also, the block lists are fully configurable. You don't have to use whatever lists you are referring to (the bluetack lists?).

PeerGuardian is blocking access to BitTorrentInc which µTorrent constantly tries to access even with "Check for updates automatically" turned off. The connection error causes µTorrent's network thread to gobble 100% CPU apparently trying to constantly access the blocked address.
1) this is a bug in µTorrent - it should not go into a CPU loop on a network error
2) why is this access to BitTorrent Inc constantly occurring even with auto-update checking turned off?
Offline
2) What about when you disable DHT? µTorrent always uses router.utorrent.com and router.bittorrent.com as DHT bootstrap nodes.
Offline
OK, that explains 2 then, but 1 is still a bug.
Thanks.
Offline
I am also having the same problem. uTorrent is using 98-100% of CPU while PG2 is active. Turning off automatically check for updates does not fix the problem. Only disabling PG2 returns uTorrent to normal CPU usage.
Offline
I think you get around the issue if you disable DHT as well.
Also PG2 is crap, it has utorrent.com in it's filters, that's why it happens.
Now, of course µTorrent shouldn't go in a loop like that, but until then, just get rid of PG2.
Offline
µUtorrent is in the Bluetack lists (the default PG lists) because it is owned by BitTorrent Inc which has made arrangements of some kind with the MPAA. Saying PG is crap because of that is like saying µUtorrent is crap because it's owned by BitTorrent Inc.
The right solution is this case is to allow the the addresses that µTorrent wants to use or disable DHT. Of course µUtorrent should fix the CPU bug.
edit: I'm on Intel (32bit), 10.5.5.

There's no legit reason to ban utorrent.com in PG. The only reason it's on the blacklist is because the person that maintains it adds and keeps IP's based on personal whims. In this case, he was upset that uTorrent wasn't made open source. There is no deal with the MPAA/RIAA/any sort of organization that has BitTorrent spying on users and reporting downloads. So no need to ban utorrent.com at all.
Offline
PG is crap because it won't protect you from anything.
The same reason torrent sites can't be shut down, is the same reason anti-p2p organizations can't be blocked. They just have to move.
Also, the only reason to use PG is if you download illegally. The only way to be safe from getting caught is to stop, I would do that if it worried you so much.

1) The default PG blocklists are maintained by Bluetack, the PG devs have no control over their content. The Bluetacks lists are used, because the PG devs don't have the resources to maintain their own lists.
2) "only reason to use PG is if you download illegally" - the same is said of all BitTorrent clients, so I guess we should all stop using them as well. For your edification, PG makes a great ad-block tool (especially for those that use multiple browsers or for browsers that don't have built-in Ad blocking) and is useful against local Apps that want to phone home.
3) The politics behind µTorrent being listed in the Bluetack lists has nothing to do with the µTorrent bug - it should be fixed.
Offline
Yes, this seems to be a bug in µTorrent/mac and we'll try to fix it.
Offline
Just an FYI, µTorrent eats CPU with any network error/block, not just the DHT seeds.
