I just ran it on High Sierra and everything looks good and works well. In all these years using Onyx, Joel has never asked for a penny, but he does have a donation page at his web site, https://www.titanium-software.fr/en/donate.html and after so many years of keeping my Mac Pro running smoothly, this altruistic Frenchman has earned my trust many times over.

Great app, helps when Mac's acting a little strangely. Non-destructive, safe routines. Easy to use. I recommend it to all whom I help with Mac problems. One thing, though: Titanium's website lists a newer version for Mojave, 3.6.7; it works fine. To all: donate! It's worth it, and they need it.

Problem with the new app. After going to the "Full Disk Access..." and following the instructions I clicked OK. The "Full Disk..." window closed. Onyx quit. I reopened Onyx again and got the "Full Disk..." window. Clicked ok. For some reason, Onyx never opens like it used to. Also, no mention, if you need to reopen the System Preferences Security & Privacy to close the lock. I am using macOS Mojave 10.4.6 supplemental update.

This is unfortunately a problem with the current version of macOS, it's not Onyx's fault. I've had the same issue with other apps. Restart your computer and it will work as it should. Also consider adding more stars to your review so as not to penalize Onyx for a macOS problem.

Continue to recommend this without any qualifications - it is simply the best app out there to do all the housekeeping etc Loads of options, you can configure what you want in terms of occasional use or set it up to do so so much for you. I just don't see how the adverse experiences claimed below could have occurred. Highly recommended - try it and I am sure you will continue to use the app for many years like so many others have!

The one thing I wish Onyx did, as an option, would be to make the Users > LIBRARY folder > visible at all times. Drives me nuts have to go up to GO, or keyboard combination to make it visible, or worse, to try and find something within Time Machine back-up, without launching Migration Assistant.

so go to your home folder and hit cmd-j, at the bottom there is the option to show your user library, select and set, and your library will show in your home directory thereafter. You can drag it to the sidebar if that helps too.

For the benefit of others, the option to Show Library Folder under 'View Options' will ONLY appear if you have the Home folder highlighted IN THE SIDEBAR. If you just have Home highlighted within a file list window, the 'Show Library Folder' option will not appear when you press Ctrl J (View Options). Once enabled, it sticks, and you will see the Library folder in Finder. This option first appeared in High Sierra.

This terminal command also works in any macOS from Lion 10.7 and up.
chflags nohidden ${HOME}/Library
depending on your permissions, you may have to preface the command with 'sudo'

There is no need for Onyx to add this, because it's already available as an option in the Finder, as others have pointed out.

I logged in specifically just to say the new option in version 3.6.3 to turn off warning about running 32-bit apps is fantastic. That warning just confuses and intimidates casual and non-geeky users, and gets them all worked up that something is 'wrong'; resulting in phone calls and texts to yours truly.

Can you provide some guidance? I can no longer open various files in Finder, and get error message that indicates "cannot be opened because you don't have permission to view it".
Trying to google this problem, it appears it is recommended to open Disk Utility and do a review and repair of permissions.
BUT: I have OSX El Capitan (10.11.6), and apparently the permission repair has been removed. SO: then some are recommending to download OnyX and repair permissions with Onyx.
AND: when I right-click on a file that I cannot open and select Get Info, at the bottom it appears to indicate that I should already have Read & Write permission.
Can you help resolve my confusion and my current inability to open various files?

@robertanema - this isn't the forum to do technical support, but here's some pointers to maybe get you in the right direction.
1) Repair permissions is still there in El Cap, it runs in the background, just not visible thru Disk Utility. That repair permissions function mainly repairs SYSTEM permissions, operating system files, who can execute, etc. The repair permissions step in Onyx invokes the same macOS repair permissions, it is identical, Onyx makes it easier to execute explicitly. From your description I think you are trying access files in Finder, I have to guess these are not system files, but just user type data files.
2) it sounds like you have an issue with USER permissions, i.e. files that aren't currently owned by the user account that you are logged in as. Are the files you want to open from another Mac that are from a different user log in, or the same Mac, but under a different account? If so, then you either you have to log in as the original user who created/owns the files, or change permissions to allow you, a different user, to access them, so go to #3
3) Are you logged in as a user with Administrator rights? You need to have Administrator rights to give yourself permissions to user files that aren't created by your account originally. See System Prefs/Users and Groups, see if your account is Administrator or Standard. If you are an Admin go to next step.
4) Do a Get Info on the files/file/folders you want access to. scroll to the bottom, Click the padlock at the bottom to unlock. You will be asked to enter an Administrator login and password. If you aren't, or don't know an Administrator login or password on this machine, stop, you can't go further. Once unlocked, select the user/group and change the privilege to whatever you want.
5) if it says you already have Read/Write, try creating a new user on that Mac with Admin rights, log in as current user that's giving you problems, give that new user read/write access to the file, then log in as the new user and see if you can access. If so, the solution may be to just transfer all your data to a new account and give that new user access.
Last resort, take it to the Apple Store or Geek Squad or Mac expert in your local area. Good luck

Before using this, I would honestly at least try Clean My Mac X. (Create a Time Machine backup or CCC backup first.) Onyx has ruined many Mac's of mine.

I am surprised to have heard this. Onyx is BY FAR the best utility app out there. If one starts messing with things they do not know how to fix or what it really does then I can see it perhaps throwing your system off into a tangent. I have tried all the mentioned above time and time again and all have failed in one department or another. Time Machine should be used regardless, but is a hassle a find if I want a quick clean the flushes unwanted data off my sysem. Clean My Mac is a scam and never does what it says it is doing, unless one runs the program several times repeating the same task to make sure it does it. Onyx is A MUST GET

IMW, I doubt that's true.
You seem to be the only one who's reported problems other than OS version incompatibility.

I'm very surprised you would also recommend CMM. I tried it and it wanted to delete a whole lot of essential files. I'd suspect that of causing your troubles, not Onyx.

Onyx is a saviour. Onyx saves your computer from all troubles you might encounter. Onyx is A Must Have.
What ruined your computer is "clean my Mac" and/or some other unreliable applications you used. Trust nobody BUT Onyx and other Titanium Software tools.
