OnyX 3.8.1

I can't rate OnyX because the latest version is for Catalina and I'm still on Mojave.

This is the Golden Crown of the very best of the 10 best applications.

The very best out there!!! Donate, post praise, talk to others to use it!

Great app. Have been using it since Mountain Lion. Nicely updated with each new OS.

My go-to maintenance app, these days. Great work.

(0)

Great app. Have been using it since Mountain Lion days, at least. Keep up the good work. Have already donated twice.

(0)

Most useful app. I've been using it for quite some time, and always found it works faultlessly. One of the more useful, and free Mac apps out there.

(1)

Some kind of introduction would be apreciated.

(0)

I immediately uninstalled it. When I opened and began process to use, the MacKeepers ransomware icon came up. To get to the Onyx app, Mackeepers kept moving in front, trying to force me to use it. I needed Apple techs to get rid of Mackeepers before, so instead of risking damage, I deleted OnyX by using Clean my Mac X Uninstaller. I'd love to find alternative to Clean my Mac...but taking no chances that OnyX is somehow connected to MacKeepers ransomware, because it's not on App Store

Where are the Onyx logs stored on a Mac?

Simply magnificent! Maintain your system and drive with no destruction of anything. This app is very intelligent, quick and secure. Will work on any version of Catalina currently available...DO DONATE for this app. Onyx is one powerful alternative to CleanMyMac that is "free" and has no issues with Catalina.

(3)

I have been using OnyX for years and wouldn't use anything else.

(1)

I've used this very useful app for many years, and found it to work very effectively and with no issues at all. The fact that it is free is an enormous bonus to all users. I'd call it one of the more useful third party apple utility apps that always works.

(1)

NOTE that v. 3.7.2 is Catalina only. Onyx is a must-have app that is very useful to get at all the little System tweaks that otherwise need delving into Terminal. There's even an easy to use manual for Terminal as long as you know what it all means.

(0)

Works as advertised. Nice to see a version for Catalina

(0)

I'm not sure if I'm using it right, what I did was open the maintenance tab, hit restore defaults, and hit run task. everything else I don't touch. Is this the right way to use it?

(0)

Will it run on Mac's Catalina (10.15.2)?

(0)

Absolutely essential.

(1)

Indispensable. Period.

We are so lucky to have Joel, the inventor of all versions of Onyx . He gives us a free system utility that works better than any other out there, including a lot of the paid ones. He asks for donations — https://www.titanium-software.fr/en/donate.html — and I do believe it is time for many of us to see that he's paid for the work he's done, for us, for Apple, and for the OS we all love. Thank you again, Joel. I know you're not a millionaire yet, but bless you for sharing your gifts!

(3)

Just started using this yesterday and so far I'm blown away! It drastically reduced the amount of space my "other" component was taking up in Mac storage. Performance seems better too. Great cleaner!

It is amazing what a small developer can do and what huge multi-national companies cannot. This app is a remarkable tribute to Joel Berre the developer!

(1)

Using it for a long time now. Very satisfied, never had any problems.Used different cleaning programs, paid and free before starting using Onyx. Recommended! and...........worth any donation.

(4)

Essential. Practical, easy to access, space-saving. An application to always have on your hard drive.

(0)

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.

(2)

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.

(0)

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!

Version: 3.6.3

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.

(0)

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.

(0)

Love, love, love Onyx. This app keeps my Mac running smooth and efficient. 5 million + downloads means they are doing something right.

(0)

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.

The essential Onyx is at v.3.6.0 with v.3.6.1 almost out of beta..

(0)

With every OS update, I immediately apply Onyx. It maximizes the positives and reduces the negatives.

(2)

Onyx has been a consistent and reliable tool for many years. I can't recall a single instance of a buggy release in decades.

(0)

Maintenance 2.5.0, 20 Feb 19 and OnyX 3.5.8, 20 Feb 19, have been released. They are both made by Titanium Software. I opened both apps and looked at their startup screens. OnyX has 4 areas (multifunction utility) to choose from. Maintenance has 1. Both are the same. I can’t see having the Maintenance app as they are both FREE.

(1)

I love this app! just make sure you create a back up prior to using it. sometimes it can get a little wacky

Noticing the details, care is taken. Easy to use and free.

The new version for Mojave is spectacular! Joel as usual has produced a powerful, simple to use and very friendly app to maintain you Mac. How he does it for free I have no idea! CleanMyMac developers need to look at OnyX and learn how to produce an app that even at NO CHARGE is fully able to verify your SSD! If you do not own or use this wonderful app, you have made a mistake that you need to correct! As I have said before, if you own OnyX and you have not made a donation you are committing a cruel and unusual act. Step up and support this amazing app and its fine developer!

(0)

I'm certainly thankful for Joel for having provided such a valuable tool for many years. But, unfortunately, the latest version broke my Firefox bookmarks (and I had lots of them).

Most annoying, is that they are now non-deletable.

Use with caution.

I bought Onyx (Version 3.1.2 (23696)from the App Store to clean up my MacBook Pro (mid 2012 running MacOSMojave Vers 10.14) The programme did the clean up well enough but continually dropped out and I spent as much time restarting the cleaner as doing the cleanup! Any thoughts on why the unexplained closure of the app happens so often?

(0)

The tool of tools for Mac maintenance! It is free, but if you don’t donate you should feel like a thief! Joel updates this app constantly. It was one of the very 1st if not the 1st to be able to verify an SSD with APFS formatting when it first appeared. At the moment not even the vaunted CleanMyMac can do this! Excellent collection of tools built in.

(2)

Downloaded it and and used the "maintenance" feature yesterday, the 1st of October, and the system performance improved; great program!

9/29/18 I had assumed that Apple Support Communities would be against Onyx, because they are against everything that doesn't come from Apple, and they like to argue too much for my taste. Anyway, I used Onyx WITHOUT THEIR PERMISSION, and it worked. It worked sensationally. I had had a couple of problems that they couldn't help me with, so I called Apple Care. They couldn't help me, either so, having nowhere else to go, I tried Onyx, and not only did those two problems disappear, but also another one that I had resigned myself to. Wonderful. Even better, Onyx fixed the problems even though I had no idea of how to use it. I just saw a command that said something like "Restore all defaults," so I chose it thinking that it could do no harm. THAT DID IT. I'll never know which settings had been causing the problems, but using the DEFAULT command brought my iMac back to its brand new condition. Thank you Onyx. I understand you need contributions. Well, you're getting mine within seconds. Thanks again.

(3)

Powerful app! It is able to verify an APFS formatted SSD when Drive Genius 5, TechTool, the new CleanMYMac and others cannot, and it is free! Other high priced developers complain that the APFS formatting is too complicated and they are having a hard time figuring it out...what gives? How is it that one small developer in France can do it and they cannot! This app and developer is fantastic! Support him! Donate for this app. Mojave version will be out soon.

Useful tool for every macOS user. Free it is .. dev should ask a small fee imo.

(2)

Works great! Doesn't mess things up while doing the standard maintenance function.

(1)

STILL a great app. Been using it for many years. I would love it if the developer could add a new feature to the Parameters section. I have a 2015 15” MacBook Pro with a 2.8 GHz Core i7 processor (model #MacBookPro11,5) running macOS 10.13.6. Quite frequently when I'm using the trackpad, when I’m trying to click-and-hold or double-click and hold to highlight some text or a file name, instead the Dictionary is activated. This is very annoying. I have not been able to find a preference to turn it off, so it would be great if OnyX offered such a feature. Thanks, and kudos to Titanium Software for all they do for us.

Is OnyX the best app to use or is there a better one in its field for the price and functionality?

(0)

Highly recommended for general system/machine maintenance and troubleshooting. Long-time user, I install on every mac of mine (and of friends and colleagues). Set up for clearing caches, purging un-needed sys files etc etc. System-specific versions means no confusion as to what version to use on your machine.

last two times I used Onyx (High Sierra) it got stuck on verifying disk. I had to force shutdown system, re-run Onyx and then everything went ok. I'm using it for 15 years and this is the first time I experienced any issues with it.

(1)

Very handy free app to handle/customize a lot of low-level macOS options. It does a good job also cleaning-up temporary system files. It does most of the things a lot of other highly priced apps do, you just need to know what you are doing.

(2)

Perfect all in one Mac utility for my must-have collection.

All in one tool I added to my must have collection. No drawbacks so far.

A classical must have.. Free!! Use and appreciate it from the very first version. Why doesn't Apple buy and integrate it in his OS ?

(1)

I've used Onyx for years on my Macs and it works great to clean the system. My only complaint is when you open the app it always asks to check the hard drive, etc.

I recently upgraded my Mac OS to High Sierra and it won't install the new version. I can't open the dmg file.
So is Apple trying to block this app!?

Not entirely sure tools like these markedly improve performance, but it makes me feel better to run Onyx every once in a while. Gives me the same feeling of satisfaction as tidying up the lounge and clearing old receipts out of my wallet.

Excellent maintenance tool. I recently installed MacOs 10.13.1 on an unsupported Mac Pro 3,1 and Safari, Mail and Updates would not connect to the Internet. After running OnyX in "Automation" it fixed everything.

Version: 3.3.7

OnyX app 3.3.7: 11 Oct 17 Maintenance: When I open the app, the icon in the dock bounces several times. Does it need to do that? Maintenance: After executing it gives you a choice to shut down or restart. Is there a way after it restarts that the OnyxX app could open automatically? Does it have to go thru the hard drive verifying again? Cleaning: Recommend that tasks concerning SSD or Fusion drives be written in red, so they stand out better. Also, is there any way the app would stop further actions when an SSD or Fusion drive is detected? Cleaning: Is there any way that after a task is done, that you can shut down or restart only once, and not after each option?

The best, free + good working! Keeps my Mac running smooth!

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.

for 3.1.9 Until this year I would have raved about Onyx but Onyx has been failing me big time lately / causing problems that didn't exist / not fixing those that did like simple permissions.. I am using El Capitan 10.11.6 but Cocktail for ElCap seems to have fixed the problems, along with completely deleting the Onyx corrupted spotlight files. Et tu Onyx? :-\

Onyx is a critical piece of my troubleshooting arsenal. Between TechTool Pro, DiskWarrior and Onyx, I have yet to fail to recover a drive or laptop/desktop - and I seem to be helping a number of other, less-experienced users. Remarkable array of options in Onyx that allows excellent maintenance of your mac. Highly recommended for all users.

I have been using this product for five years on an ancient MBP 4,1 17", from Lion to Sierra. I find myself coming back to it time and time again, and using it over other products (that are not quite good actually - MacPilot is one). Onyx is simply excellent and has helped me out of a few bad decisions.

be aware, as of April 2017 the 'Related Links' on this page to previous versions of Onyx for older versions of macOS are out of date. Onyx 3.1.9 is the latest for 10.11, El Capitan Onyx 3.0.2 is the latest for 10.10, Yosemite Onyx 2.8.9 is the latest for 10.9, Mavericks It may be that just the descriptions are incorrect on this page, and the actual downloaded file is the latest, but just to be safe, go direct to the developer site to download if you have an older version of macOS.
