µTorrent Mac 0.9.2 alpha


Recommended Posts

New alpha for µTorrent Mac! We've added support for UDP trackers in this release.

Note on platform support: With this release we are excited to finally support machines with PPC architectures. At the same time we have made the decision not to invest in making µTorrent compatible with 10.4 (Tiger). We know that this will be disappointing to some users, but we feel this is the best balance to strike between legacy platform support and accelerating the development of a Mac client as advanced as our Windows version.

I was downloading a torrent on uT for mac I stopped the torrent, installed the 0.9.2 alpha and started uTorrent. The torrent that was half-done was giving me a HTTP Error 404 in the tracker status, but another torrent from the same tracker that was completely done was scraping/seeding fine.

Also, I tried refetching that torrent and re-checking, but still the HTTP Error 404 showed up.

I am on a Macbook with Mac OS X 10.6 and 4GB RAM.

Why would it get released before its ready? This build is marked "alpha" for a reason. And that reason isn't to piss you off.

Why would it get released before it's ready? Because that's what most app's dev departments do. Despite being in beta uTorrent is already superior than many other clients for the mac, some not even in beta. It still has some bugs, but it is fully usable.

Only added bug I have noticed so far in this alpha is that now it's harder to get uTorrent to stick to the speed limit. Seems to actually be about 5k above what I set.
