Not good for Yosemite, better for older OS
This would be (used to be) a really great utility to display info if it reported accurately, but it doesn’t, not in Yosemite (though before Yosemite, it reported reasonably accurately). The status bar display for things like network send/receive and disk read/write values are hard to quickly read (to glance at and get a feel for the current activity) because of a symbol that displays before each number and moves with it. Also now there is this X disaster that is easily clicked beside the quickly changing app names, if you touch it you don’t get a warning, it just end the process, and often crashes your computer or looses your data - there should never be any kind of kill process button in something like this!
Yosemite manages memory differently than previous OS, and I’ve found that Yosemite utilizes way more memory (which is good, better to make use of it as dynamic cache than just having it sit there unused) and does have to do cleanup at times, but it does it better than previous OS, and better than this app. Though this app does leave more memory ‘free’ after it’s cleanup, that is kind of counter productive in Yosemite. I’ve also found that using this apps auto clean actually overall makes things slower and causes more and longer ‘stalls’ (because it’s busy cleaning) in Yosemite. Not using this app to either auto or manually clean makes for an overall smoother and faster running system (in Yosemite - previous OS I found this app helped overall, though the ’stalls’ while cleaning were very annoying).
If you have Yosemite, the only info of some use is the overall CPU and memory use graphs, though the memory graph is going to be almost always at max (and the graph sections don’t come close to agreeing with Activity Monitor so they are inacurate).
This used to be one of my fav utilities years ago, but it’s become less and less accurate, useful and even dangerous and less necessary; maybe if it’s fixed to report accurate info, and some other major changes made (like value display improvement, removing process kill mess, removing music function, etc), it will be a good app again. Until then, I’d suggest other basic info display apps.
More Detail:
The utility totally misreports memory use (comparted to Apple’s Activity Monitor) and always completely misses apps in its ‘top processes’ (current highest useage) list displays (and I don’t mean system processes, but things like Dropbox, other user utilities, etc) that show accurately in Apple’s Activity Monitor. E.g. The memory list will often only show all highest use apps using well under 90 MB each, yet shows 4+ GB memory in use overall, leaving out the real high use apps (not system processes) that are actually using hundreds of MB. Same totally inaccurate info for the CPU usage list. Things like the network send/receive display should have units AFTER the value (123 MB/s ^), not split before and after (^123MB/s) to make values easy to quickly read. As for the process kill option mess, the process names jump around all the time, how in the world can you even intentionally click a moving ‘X’ to kill the one you want without accidentally killing something else important? This app is struggling to stay up-to-date with current OS, but it isn’t working out so well.
