CleanMyMac 3 Review - Should You Buy?

There is no deny in the fact that Macs are one of the most stable, fastest and reliable computer available in the market and the main reason behind their success is the powerful combination of the hardware and Apple’s operating system, macOS. The most basic version of the MacBook Air or MacBook Pro comes with 128GB SSD, and if you are a heavy user, this storage space will be filled in few days. Similarly, if you are running more than three programs on your Mac, it may eat up all the RAM on your Mac making it slow and laggy. So, if you are facing such type of issues, you can resolve them using a cleaning program on your macOS.

There are plenty of programs available on the internet which will let you clean your Mac in a few seconds deleting the old files from computer or closing the program from the background. A unique Mac cleaning program should be able to intelligently remove the unnecessary files or closing the program that you don’t want to use.

One of the main reason behind full storage on your Mac is the old mail attachments. Moreover, unlike Windows computer, Mac users can directly put the applications in the trash folder. But the CleanMyMac provides the perfect way to delete such type of files from your computer.

One of our most favorite feature in the CleanMyMac 3 is the presence of monitoring feature which acts as a doctor for your Mac and will continue the health of the battery and the hard disc. If your Mac is heating way too much, you can use this feature to monitor the temperature of your Mac and can also check the battery life of your macOS.

My Review

I am using MacBook Pro 2013, Retina display with Core i7, 8GB RAM, and 256 GB SSD. Usually, most of the personal data on my computer is stored on the cloud storage, but I have tried CleanMyMac 3 to get space and speed up my Mac OS X, and the program proved to be very effective.

about my mac

First of all, I used the Smart Cleanup feature in CleanMyMac 3 which took less than one minute to complete the scan process. The great thing is that I was able to get 4.87 GB of storage within less than five minutes from my computer. You can minimize the program, and it will show a notification on the right-hand side of your computer.

After scanning, I was able to select the files which I want to remove from my Mac. So, if you feel like there is an important file saved for the particular application, you can uncheck the option in CleanMyMac. Moreover, the program has already got the privacy feature, so, one will need the administrator’s password to complete the clean-up process.

We also tried to use the deep scan process for individual application and the mail application had the most of the junk saved on Mac. So, this program will delete all the attachment from different Emails. In other words, all the emails are saved for offline on your computer, so, you can select the items that you want to keep or delete from your computer. Another useful thing present in the CleanMyMac 3 was the arrangement of different files for file types.

For example; it automatically separated all the documents under one tab, Pictures under one and archives under another tab. Similarly, under iTunes Tab, it had the downloaded software junk files, applications, and cache for other files.

Apart from the storage, I was able to free plenty of memory of the computer just by clicking the Tiny button present at the top bar of the computer. Moreover, I also used the "Maintenance" option in the CleanMyMac 3, and it was proved very useful. Lastly, the shredded feature worked perfectly to room the valuable data safely and securely from the Mac.

    I'm concerned because I cleaned ~15GB of space the other day by moving big files and deleting folders and clearing caches. I also used the cleanmymac advice so I thought I would try the free trial but now I see that all of the sudden I only have 7GB of space free again. How is this possible? Is it possible that cleanmymac is taking up more space so I purchase the license?

      Hi Cassandra, why do you have 7GB of space? CleanMyMac 3 will scan System Junk >> iPhoto Junk >> Mail Attachments >> iTunes Junk >> Trash Bins >> Large & Old Files

      This image will explain about System Junk,...(

      And I think you should purchase the license now because the free trial can't remove more than 500MB of unneeded items across all cleaning modules. Moreover, you only can get 50% Off On MacPaw’s CleanMyMac 3 in this week.
