I looked at etrecheck.com, and it directed me to the App Store.
The basic d/l is free; there's an in-app option to purchase advanced features for Ca $20+.
The basic d/l is the same functionality as you've got now (which I'm still using because I hate the new GUI).
If you use MacUpdate, d/l from
EtreCheck Pro 5.0.7. They offer a d/l option on their
search page, but I'd be wary of it.
