    BleachBit is open source and does a thorough job of deleting various files that could reveal what you've been up to, from cookies to temporary files and other junk. It can't replace CCleaner on Mac, but on Windows and Linux it is arguably better and more trustworthy.

    It doesn't have an automated option as far as I can tell, it seems to only work manually.

    It's FOSS, no bloat, and does a perfect job.

    It's not just a good alternative to CCleaner, it's even better than this. I can not confirm the Bundleware, at least not since a long time ago, even File Puma, Glary's own page is a highly recommended site to find and download software of all kinds.

    Glary Utilities, to my knowledge, has not been hacked and packed with malware.

    Powerful, but slow, and complicated. It's very aggressive, and difficult to configure.

    I'm really surprised how something this good can be free and most importantly ad-free. Definitely going to donate to keep up the good work! Thumbs up

    Onyx is basically a GUI tool for all the housekeeping tools that macOS has on the command line. It will allow you to reset/clean up and clear most of the caches and tools that are in macOS, but have no dedicated GUI. In so far it is a "safe" choice, because it doesn't do anything that isn't provided for by the OS itself, it just offers a GUI and all the tools in one place. And for free. What's not to love?

    To compare Onyx with CCleaner is like comparing an apple to a CPU. They are incomparable.

    Microsoft PC Manager is a useful addition to your toolbox. I'm sure it can get down in to nooks and crannies that even CrapCleaner was scared to dig in to. I don't see a registry cleaner, but it does have a handful of other tools. On the other hand you need to pay attention, and disable it's default "revert system settings, browsers and etc. when you first use it. I disabled all options that sounded like they might be used for telemetry, also. Anyway, pending Malware being discovered in it, I'm going to give it a thumbs up and keep using it for now. :)
