@JML you can also delete the folder ~/Library/Containers/Safari/Webkit/WebsiteData/Default if you're not worried about the databases. that will also get Cookie running.
v6.8.2 is available on my servers now, and will be in the App Store after review by Apple. It fixes the hanging issue without the need to close Safari on first run.
@SweetP Version 6.8.3, released today, just hangs. The progress circle (?) keeps spinning and spinning... It uses 86% of CPU. I had to revert to 6.8.2.
@SweetP Safari and Chrome. When I did the update the progress circle kept going for about 5 minutes until I shut it down. I have the Advanced window option when I "show Cookie."
@JML Maybe it's 6.8.x that has the problem. The progress runs for a LONG time in 6.8.2, also, going from 44% CPU down to 32 when I took the screen shot!
Maybe it was a transitory problem. I just tried 6.8.3 again, but shut down Cookie before updating it. The progress ran for under a minute, and Activity Monitor showed it was using 62.3% of CPU, then dropped to 40.6%, and then .4%, then Zero.
@SweetP Is it normal for the heavy demand when Showing Cookie, or shutting down the browser? It went to 96.1% before slowly going down to zero CPU. Is this from the app checking all the cookies and deleting non-Favorites and non-Bookmarks?
