I took a chance that I am not certain whether I will regret it or not.
I bought Bartender 5 for $20, which includes an update to version 6 being released over the next month or two.
Now that I am on Tahoe DB 7 (I believe that is the version), I have been testing out the Alpha releases of Bartender 6.
They are a complete mess. Once installed, they bring the computer to a crawl. It's hard to see if it's a CPU issue, as I can't access anything on my MacBook Pro until I force quit the app. I have read similar complaints from others using the Alpha software.
Mind you, I realize Alpha isn't beta, so these kinds of issues are normal. What worries me is that I have contacted the developers with each Alpha release, letting them know of the issues. They keep announcing the issues have been fixed with each subsequent release, and yet the Alphas seem to get worse with each update.
