"I’m a new user of this app. I just discovered they have a beta that works on 10.4. I alway figured that ObjectAlloc was good enough, but I was wrong. OmniObjectMeter makes it so simple. Finding leaks is still time consuming, but it’s the best tool for tracking down each alloc, release and autorelease. 4.0.2 will be released shortly with a few memory leaks plugged. Thank you Omni!"

ps: I am just a Path Finder user myself. Have nothing to do with that blog.

No bad, OmniObjectMeter should be the best tool for tracking down each alloc, release and autorelease. I use it with Cocoa and Unix, reaaly great.
