One app that I would not recommend, based on the number of complaints that have been posted in this forum and elsewhere, is CleanMyMac. As an example: CleanMyMac cleaned too much.
I notice lately my iMac has been a little sluggish and was looking into some apps that can tidy things up to when I first bought it. What do you guys think about this app or ones like it, good or bad?
If you want to enhance the performance of your Mac, be sure to check these two articles, do not just use applications, that promise to do it for you.
I won't use any of the so called Mac Maintence apps.As I recalled, CleanMyMac is the biggest offender, a borderline virus for the Mac. I mistakenly tried it serval years back, it totally messed up my Mac. Don't do it!!!!

All so-called cleaning apps for OS X are lies.
OS X will handle junk by itself.
If you want to speed it up, consider freeing up space in the drive, or change the HDD to an SSD.
It's not a virus. It does what it says on the tin. Whether it's worth the money for you is another question.
OS X doesn't handle junk by itself, hence why I have to clean out gigabytes of useless Safari top site thumbnails with regularity.
Actually, it does. However, OS X is not going to arbitrarily or automatically empty your Safari cache, history, cookies or web site previews, as you may need them. Those things are up to the user to maintain, which is quite easy to do within the Safari app itself. There is no need for any third-party maintenance app or user interference to properly maintain OS X.OS X doesn't handle junk by itself, hence why I have to clean out gigabytes of useless Safari top site thumbnails with regularity.
^This.Onyx has the best reputation of them all.

That's not a myth. There is no noticeable improvement offered by any of those apps/scripts for the vast majority of Mac users.Two myths -
1) Apple OSX takes totally care of itself and doesn't gain any improvement in use by 3rd party apps/scripts.
This is ironic, coming from someone who says:The trouble with those that believe Apple OSX takes care of everything is a lack of understanding as to what really goes on under the hood
This truly displays "a lack of understanding as to what really goes on under the hood." Browser histories have zero impact on system performance. They are extremely small files that do not require any system resources. Also, unless there is a specific problem with a specific app that requires deleting a log/tmp/dmp file, it is wiser to leave those alone, as they can be useful in troubleshooting. They don't take up a significant amount of space, unless you have a specific problem. User's shouldn't have such little free space on drives that such files would be required.try to keep web browser histories limited as well as certain log/tmp/dmp files and so forth.
Actually, it doesn't do a good job in deleting app-related files. If you elect to use such apps, be aware that in most cases, app removal software doesn't do a thorough job of finding and removing files/folders related to deleted apps. For more information, read this and this. If you just want to delete the app, drag the .app file to the trash. No other software needed. If you want to completely remove all associated files/folders, no removal apps will do the job.I have been using CleanMyMac for many years now. It's updated frequently, and it works well for cleaning up apps after you delete them.

I'm not sensitive at all. Just debunking misinformation before it misleads those who may not know better than to believe some of the things posted here.My my someone is rather sensitive here.
LOL. I've been very familiar with how browser histories and cache works for many years. I don't need to look anything up. My statements stand. If you have what you believe is a valid argument otherwise, perhaps you should post specifics, rather than a general "look it up" recommendation.Why don't you look up the reasons to delete or trim browser histories and cache. You might learn a valuable lesson.
We're not talking about a drive which is almost full, which isn't going to happen because of logs, temp files, caches or browser histories. If a drive is full, unless there is a specific problem, it's full because of user files stored on it, which will take up far more space than all logs, tmp, dmp, histories, caches, etc.There are various files that grow in size and take up space, as well some get read and that too can slow a system down when drives are beyond a certain level of being "full."
This is exactly why routine deletion of the file types you describe is unnecessary and counterproductive. If someone has a performance issue, they may need log files to troubleshoot. If you delete them, you've lost that advantage. If you delete cache files, system performance is degraded while those are being rebuilt. Caches exist to improve performance. Deleting them without specific reason doesn't free up as much space as moving some user files to external storage, and it hurts performance. Also, if the performance issue is with a certain app, such as Safari, caches, cookies, etc. can easily be deleted from within the app; no 3rd party "maintenance" apps are needed.When people talk about slowness of a computer, it often relates to the applications they are using and all things associated.
That is your uninformed opinion. Nothing more.Now please don't take this to heart but you are really not offering any information of value here
Just to clarify, it is not a virus (infection and propagation without user interaction).
No after how you put it, it is a malware to say the least.
A nice short list of options to improve Mac performance -
Hardware
- SSD is faster than standard mechanical drives.
- RAM while many systems run fine on 4 gigs, consider if possible more.
- Keep the computer from over heating as this causes all sorts of issues.
House cleaning -
Outdated caches can slow down start ups.
Some apps may be 'bad actors' and slow down overall performance. If you suspect an app is behaving poorly, you can check the activity monitor and see if it is eating up processes and memory. If you are not using that app at the given time, consider killing the processes.
Widgets - simple, if you have widgets you don't use, remove them. (More true of older versions of OSX)
Login/start up - check to see which apps are engaged upon login/start up. If they are not required, remove them from the start up.
Software updates - hit and miss. It usually fairs well to keep software updated. However, sometimes it is worth waiting a few days before upgrading to see if the upgrade itself has issues.
Safari - lots have been written on how this is a memory hog application. If you like Safari, use it but consider keeping it as streamlined as conveniently possible. While cache is a good thing, it might serve well from time to time to delete it and start a-new. As well, over sized histories serve no real purpose. Consider clearing history or using Safari "reset" every few weeks.
Mac's own house keeping - Many of us simply keep our computers on all the time and possibly use sleep. This might appear convenient but from time to time it is valuable to shut down or restart the Mac as Mac's own house keeping is queued by a power up and/or a power down. Tools like Onyx provide an opportunity to run some of these Mac house keeping scripts and tools on the fly rather than depending on shut down or start up to queue them.
Drive overload -
Depending on the drive and your software install, Macs can start to get sluggish if the drive is "too full." There is no set rule or standard as to when a drive is too full. However, many consider it "safe" to keep at least 20-25 percent of the drive at all times free. Thus, if the drive is 75-80 percent full, you might take some considerations to free up more space.
As I mentioned before, there are various files that can be deleted and applications will start a new replacement file - various logs, temp files, and more. These types of files need not be removed with high frequency but from time to time if found beneficial. Caches reconstitute themselves rather quickly for most solid performing apps as well as logs and temp files.
Empty the trash out. Some people suggest that for SSD drives, to wait until it is somewhat full before emptying as to avoid unnecessary read/write of the drive. It is unclear if this is of real value.
Using third party tools for the drive - simple tools like Monolingual can free up considerable space. As always care should be taken. Monolingual simply removes installs of languages that you elect to remove. Some software provide choices of language but the language "packs" are all installed. If you use only English, you don't need German, Spanish, French, Mongolian or whatever. Stripping out these other language packs works quite well to free up drive space.
Defrag - Microsoft, IBM and Apple at one time or another insisted their systems don't require any defragging yet Microsoft years ago started implementing a defrag tool and IBM's OS/2 had enjoyed 3rd party defrag tools that showed marked improvements on disk handling and speed. Today, with SSD, defrag might not be a great option but for standard drives, that deal with messy large and small app generated files, it can be useful to consider. The idea is unfragment files and if possible locate in a contiguous fashion. Tools like iDefrag as example can do this and also more advanced improvements. The caveat of course is drives that are failing that are engaging a defrag tool can end up with damaged files or systems. If your computer is not with an issue of this sort, you might* consider it for a mechanical drive.
Alternative to defrag - The easiest alternative is to use a tool like Carbon Copy Cloner and back up the entire system. Reboot from the back up to see if it is working properly. If yes, then re-install your home drive from the back up. What this will do is lay down files in a non-fragmented form and with some instances, create contiguous files. This holds more value for those with SSD drives as a defrag tool does lots of file moves and this back up restore does limited read/writes/destroy.
Permissions - another possible tweak but has peoples on both sides of the argument of value. The pro group suggests that from time to time it is worth while to do a permissions repair on systems that have been up and running or rather, been used for months on end and loaded with software. For me, I have found no improvement that can be noticed in performance but it remains an option some advocate.
Killing processes - its not a bad idea to look at the activity monitor from time to time to see which apps over days are using the most memory and processes. You may find that your system is simply memory limited. If so, consider opening up less applications at a time. Of course, if your Mac allows for upgrades of RAM, that too can be considered.
Hope this helps anyone looking to do some tuning/tweaks to their system and as always, read up first on what you are trying to do to get a more in depth informed view of the task at hand.
Nice tips and I might add that a clean install every 2 months a good too keep things running good.
Your saying sooner?
Some good stuff in there, with only a few "adjustments":A nice short list of options to improve Mac performance
This isn't true. You can run Macs for months at a time without restarting or shutting down, with no adverse performance impact. OS X has maintenance scripts that run daily, weekly and monthly at prearranged times. They are not triggered by shutdowns or restarts or power up events. If the Mac is in sleep mode at the time of a scheduled maintenance event, that script will run when the Mac is awakened. If the Mac is shut down at the scheduled time, the script will not run on power up. You can use Maintidget to see the last time the scripts were run, or to manually run them.Mac's own house keeping - Many of us simply keep our computers on all the time and possibly use sleep. This might appear convenient but from time to time it is valuable to shut down or restart the Mac as Mac's own house keeping is queued by a power up and/or a power down.
10% is usually sufficient free space, but on newer Macs with much larger drives (0.5 TB and more), even a lower percentage will be fine.Depending on the drive and your software install, Macs can start to get sluggish if the drive is "too full."

Some people repair, or recommend repairing permissions for situations where it isn't appropriate. Repairing permissions only addresses very specific issues. It is not a "cure all" or a general performance enhancer, and doesn't need to be done on a regular basis. It also doesn't address permissions problems with your files or 3rd party apps.Permissions - another possible tweak but has peoples on both sides of the argument of value.

Disk Utility repairs the permissions for files installed by the Mac OS X Installer, Software Update, or an Apple software installer. It doesnt repair permissions for your documents, your home folder, and third-party applications. You can verify or repair permissions only on a disk with Mac OS X installed.
If repairing permissions results in error messages, some of these messages can be ignored and should be no cause for concern.Does Disk Utility check permissions on all files? Files that aren't installed as part of an Apple-originated installer package are not listed in a receipt and therefore are not checked. For example, if you install an application using a non-Apple installer application, or by copying it from a disk image, network volume, or other disk instead of installing it via Installer, a receipt file isn't created. This is expected. Some applications are designed to be installed in one of those ways. Also, certain files whose permissions can be changed during normal usage without affecting their function are intentionally not checked.
