Should You Install CleanMyMac 3?

CleanMyMac 3 is advertised as a useful application for Mac maintenance and optimization. It offers users a plethora of impressive features like one-click cleaning, applications uninstallation, junk removal, etc. Since most of these features do not ship with macOS Sierra / High Sierra by default, many Mac owners choose third-party apps as a universal remedy. CleanMyMac 3 has received positive user reviews, so it can be assumed the application doesn’t bear any potential dangers. Still, many experienced users doubt the necessity of using third-party utilities for Mac optimization. Instead, they offer alternative ways of keeping your Mac maintained.

How to Maintain a Mac in Good Shape?

Before installing any third-party software, try following these simple rules:

1. Create extra system backups

You can’t have many macOS backups! Back up your Mac as often as possible using the Time Machine utility. Make sure to back up from the original data directly, and not make the ‘copy of a copy.’ Use alternative backup methods. Keep backup files in different places and make them easy to access on an external drive or a cloud storage.

2. Make regular system and app updates

Configure automatic update notifications in the App Store or Software Update (depending on the Mac OS version) preference pane to receive timely updates. Keeping your Mac updated will ensure its stable performance and prevent any malicious activities. Making regular software updates is especially important to guarantee the stable performance of the device drivers. Timely updates will also prevent possible compatibility issues in case of installing any third-party apps.

3. Refrain from installing crapware

The Apple support community members warn Mac beginners about installing any toolbars, add-ons, cleaners, boosters, etc. And, in most cases, they are right. In general apps like this are useless or even dangerous, except for a few useful ones. Despite CleanMyMac 3 is not a dangerous app, users are advised to resolve their issues in the manual mode before resorting to any third-party applications. Unlike the above example, the MacKeeper app is a scam application capable of causing serious damage to your Mac.

4. Differentiate web browser extensions

Very often, users ask if they should install web browsing extensions. Most of the browsing add-ons are safe and easy to remove. However, some of them can lead to browser crashes and malfunctions. For this reason, users should be cautious and install only trusted browser add-ons from credible sources like Safari Extensions Gallery.

5. Steer clear of malware

Being a UNIX-based operating system doesn’t make Mac OS X resistant to malware or viruses. Malicious applications can hide underneath the mask of legit software. Some malware can be resistant to the built-in Mac OS X protection. Third-party antiviruses aren’t an option here since they can nest malicious agents and system vulnerabilities. Randomly, you can come across a web page telling that your Mac is infected with a ‘virus,’ or that something is wrong with it. Never trust these kinds of web pages – they are a scam!

6. Keep your startup disk clean and healthy

Macs equipped with SSDs are prone to fill up with system junk quite fast. Users of macOS Sierra / High Sierra can use the Optimized Storage toolkit to transfer sensitive or important data to the iCloud storage. Alternatively, you can store your data on the external drive to unclutter your startup disk. Keeping at least 15% of your startup disk free can ensure steady performance.

7. Use “heavy-duty” maintenance only when necessary

Have you ever performed any of the following?

  • PRAM zapping;
  • SMC reset;
  • Rebuilding the disk directory;
  • Checking the HDD for bad blocks;
  • Repairing disk permissions;
  • Virus scanning, etc.

All of the above methods are mostly serious troubleshooting methods, not preventative! They shouldn’t be taken lightly – only when a serious issue needs solving.
