The more important question is: Does it work well yet?
no, definitely not
Don't overlook it just because of your backwards bias against the vendor. It wasn't originally developed by MS anyway -- Sysinternals were consultants that got acquired by MS.
Something you should aspire to.
It initially listed a lot of processes, but failed to display anything in the three main columns (CPU, footprint, memory), and nothing at all in the details at the bottom.
Then, when the privileged helper was installed and approved through Login Items, nothing came up ever again. All panels of the window are now blank, even after a full restart of the app.
Edit: I did not build from source, I used the downloabable DMG from the release assets.
