Chapter in this post:
A few days ago I received the message that there is an offer of the system cleaning software CleanMyMac from MacPaw. Basically, I always cleaned up my Mac by hand and deleted old backups or the like when the hard disk space was a little tight again - and with an SSD drive it is somehow chronically too small. As a guideline, it is said that the system hard drive with an SSD should have at least 10-15% free spaceso that the system has enough space to "swap", that is, to swap large areas of memory onto the disk for a short time and use them again later. If you have less than 10% free memory, the Mac can always become sluggish because it has to work a lot more on the hard drive than necessary.
Recently the new version of CleanMyMac came out: "CleanMyMac X". I have you here is a small contribution written about the new functions, but if you want to strike quickly, you will find it here in the shop still offer prices. I have this SetApp subscription and that includes CleanMyMac X - so no reason for me to have to buy quickly. ;-)
Up until now, the software "DaisyDisk" had always helped me to empty storage space. It scans the system for large folders and files and then graphically shows them quickly for the eye. The CleanMyMac 3 software sounded like a "more comprehensive" tool, as it not only locates large files, but also collects caches, system residues from old programs, mail attachments that are no longer used, data junk from iTunes and much more and offers them for deletion.
Clearly, I wanted to test the program on myself, because who could be a better test subject than me - since I've been fighting against insufficient hard drive space on my MacBook Pro 15 "for years. The tool also cleans up the system, to make the Mac faster overall, but I don't really have a problem with that, which is why my test is aimed more at disk cleanup.
After a short e-mail with the software company MacPaw, I was sent a license code for the full version - free of charge against the promise that I would write a test report. And I am only too happy to do that - but I also "warned" the marketing department that I would honest report who will definitely take a critical look at the software.
After the installation, the program is very clear. A menu on the left-hand side keeps the areas ready that can be scanned:
Underneath there is an area "Utilities":
All points are explained again if you click on them once. You can find out, for example, that "system remnants" can remove temporary files or delete unused program code or unused languages from the system without affecting the system's function. All other points are explained as well, but I will go into more detail about them later.
What I have concealed so far: At the top of the menu there is a "Smart Scan" button. This enables a global scan to be triggered on the Mac, which includes all sub-items and "smart" only selects those files that are definitely no longer needed. Of course, I chose the button first. After a good 20 minutes, my entire MacBook with a 768 GB SSD hard drive was scanned and 44 GB (yes, actually!) Were found by Smart Scan and suggested for 1-click cleaning.
As you can see in the sidebar, even more files were found in the individual areas that could possibly be deleted, but these were not all selected because the user should keep an eye on this data if he does not want to keep it . The Smart Scan has already found a good chunk of potentially free hard disk space with 44 GB.
Of course, I didn't do that, because I wanted to test the other areas individually and not fix all the problems in one go. :)
At the top right of the CleanMyMac window there is a button called "Dashboard". This takes you to an overview that shows how much memory is occupied on the hard drive and what types of data (films, programs, music, etc.) it is occupied. The status of the battery in a MacBook and the utilization of RAM memory and processor are also displayed.
You can also get a mini view of this window by clicking the CleanMyMac icon in the menu bar. This gives you a quick overview of the utilization of the hard disk and the RAM.
The RAM can also be released directly via the menu bar with CMM3, if you want. In my test, about 16 GB of 150 GB of RAM (all but 7 MB was occupied) were released again with one click. Personally, I think this function is superfluous, because OS X itself also releases RAM, but only when it is needed. So it is normal for the memory to be full after a long period of use. However, this has no negative, but positive effects: programs that are already open start faster the second time they are started.
For laypersons in particular, it is important that programs are easy to use and that their functions are transparent. CleanMyMac is exemplary because every area in which you can search for deletable files is explained in detail. So you quickly know which data will be affected by the deletion and what effects this can have. If you want to know more, click on the small question mark symbol on the respective screen and you will then get to a (unfortunately English) description.
The division into different areas helps to deal with certain file types and types of media. In this way, you can be sure, for example, that you are throwing only photos into the bin in the "Photo data remnants" area and not e-mails. There are some other clean-up apps that proceed very "comprehensively" and search the entire hard drive for all possible - from their point of view useless - data and then delete all of them. I would not recommend this type of "cleanup apps", for example, because you can rarely decide in detail what is deleted and you also get little information about what the software actually classifies as "garbage" and what not.
With the Smart-Scan function of CleanMyMac 3 you have a comprehensive search and delete many file types at the push of a button, but here the app proceeds very "carefully" or "smart" and only deletes what really does not lead to any functional restrictions can. Private photos or mail attachments are not touched here.
The CMM3's "Recycle Bins" function is worth an extra paragraph, because it not only empties the Finder Recycle Bin, but also that of the Photos and Mail apps. But what is a really good feature: With this function you can also get files from the recycle bin that would otherwise always throw a Finder error message. I had serious problems with them a few months ago resistant files in the recycle bin and had to use an extra app for it before they were really gone. From now on, CleanMyMac will do it for me - and for you, if you want.
You may be wondering, but there is an enormous amount of hard drive space on every Mac that can be "freed up" by deleting files that are no longer needed. With my MacBook alone, it was over 768 GB on a 100 GB SSD hard drivethat I have with CleanMyMac could shovel free - and that although I have already thrown out larger files and folders with DaisyDisk here and there and have not let my recycle bin grow over 1 GB. Now you are probably wondering what can be saved there?
Without going into depth, I can give you a few points that CleanMyMac records and that will surely provide you with more free hard disk space:
You don't have to be a great math genius to see that we're already at over 100 GB of free hard drive space. This means that the load on my SSD is well below the limit of 90% full capacity and I don't need to worry about the space of my hard drive for a few weeks or months. :)
As mentioned above, in addition to the various scan options, there is also a "Utilities" section. At first I didn't take a closer look at them, but the MacPaw team did a good job here too and set up a few practical tools, which I would like to present to you in detail here.
You might think that to uninstall, you simply drag most Mac apps from the "Applications" folder to the trash, and that's all there is to it, but in practice there are always leftovers: files with settings, cache folders, and similar data gradually litter your Mac towards. The "Uninstall" tool in CMM3 gives you a list of all programs that are installed on the Mac. If you select a program here and delete it, you can immediately see in a list the linked files and folders that you might want to delete with or should delete.
Program reset: Another great function in this tool called "Program Reset" is very practical and almost invisible. This function only deletes the settings data, but not the program itself. This often helps if programs crash with the message "Program XYZ terminated unexpectedly". It is not uncommon for it to depend on files that the program creates again after the reset if you delete them beforehand with "Program reset".
Under the item "Maintenance" you can repair access rights, delete the DNS cache, rebuild the mail database, run OS X maintenance scripts or even recreate the Spotlight index. All things that can be solved differently, but here they are nicely collected in a list. Not absolutely necessary, but nice to have!
Here you can delete chat data from Skype and the Messages app, delete cookies, empty the browser history and delete other personal data that was created in browsers. This not only for Safari but also for all other browsers that are installed.
The "Extensions" area is very exciting, because here you will not only find extensions that are installed in the browsers, but also login objects that are started when the user logs in, finder plugins, start agents, system settings, programs and services Finder plugins. Often such scripts run unnoticed in the background and it is usually not easy to remove or uninstall them, as they are distributed in many different folders in the hidden library system folder. With this tool from CMM3 it is done with just a few mouse clicks.
While going through the list, I found a number of scripts that were running in the background and that I definitely no longer needed because I no longer use the programs. Even if it doesn't accelerate the system noticeably, it is certainly better for the stability of OS X if you only have the most essential things running here.
The "Destroyer" tool is relatively unspectacular - even if it has a martial name: it safely deletes files. This means that the file is overwritten several times with zeros so that it can no longer be restored - even with special data recovery tools.
The tool can also be used to delete files that would otherwise give rise to error messages in the Finder. For example, you can delete data that the system is somehow still using.
As you might have seen from the previous article, I am very enthusiastic about the Mac app. I think it is especially recommended for people who often struggle with a full hard drive or who can install and uninstall many programs and keep the system clean with CleanMyMac.
If you have an iMac with a 2 TB hard drive and just surf and email a little or create a few documents with Numbers and Pages, you probably don't need CleanMyMac, because your Mac will hardly reach the limits of your Mac - neither in terms of processor performance nor hard disk space. But if you - like me - use a lot of different programs with high requirements (Adobe Photoshop, 3D rendering, video editing and the like) on your Mac and perhaps also work on a MacBook that is always marginally full in terms of hard drive anyway, CleanMyMac should be a reliable and have found a very good all-round clean-up program.
Some file types, such as aborted iPhone backups, browser caches, old mail attachments and the like, can also be found by hand if necessary and can be deleted - but I don't have a Mac to spend hours in some folder structure. With CleanMyMac it is so much more elegant: One click on the "iTunes garbage" area, one click on "Scan" and after a minute I get a list in which even the backups that are old or canceled are preselected. The last backups of the respective iOS devices are not automatically selected by CleanMyMac 3 - this shows that the Mac app is actually "smart"!
I can only recommend the Mac app, and I'm sure I use it a lot to clean up my MacBook Pro.
