The other half of what TinkerTool and Onyx do is provide some advanced/hidden OS settings which can be useful. But with those too, the 'cleaner' functions are best used during an attempt to fix a serious problem, not as regularly scheduled maintenance. These are both free, from very respected Mac developers, and do most of what Disk Clean Pro plus a lot more.

Two very reputable Mac utilities are TinkerTool and Onyx. And as I said, most do not need doing or will not result is much benefit. The specific tasks that Disk Clean Pro performs are unremarkable because there are numerous Mac utilities that do them. The most notorious is MacKeeper.stay well away from that one. I put it that way because there are some alleged Mac 'cleaner' utilities that don't have much benefit but install questionable software. Sure, cleaning caches frees up disk space, but the nature of a cache is that it is going to fill up again soon, so cleaning caches is not a permanent cure for low disk space.ĭisk Clean Pro appears to be harmless. That should be a very occasional diagnostic task, not a regular maintenance task. The only reason to delete cache files is that they have become corrupted for some reason, or out of sync with the data they are supposed to be caching. But today, some extra log files aren't going to slow anything down.Ĭache files are there to make things faster, that is the main purpose of a cache.

On old Macs (15-20 years ago) it might have made more difference because disks were much smaller and much slower. On a modern Mac there should not be much performance benefit from log and cache cleanups. It also has a 'memory optimizer' feature for RAM which is only marginally useful, since RAM gets completely reset on a Mac reboot, so a reboot would have accomplished the same result anyway. I checked out its web site and that is mostly what it does. I think it deletes mostly old cache and log files.
