Mac Disk Cleanup: The Best Way to Make Your Computer Perform Better

You might think that you treat your Mac better than anyone else. However, when it comes to the serious drawbacks in the work of its system, many users panic being helpless like little babies. They almost forget that it is possible to find the solution to any problem in the world of IT thanks to the impressive opportunities the Internet provides.

Better Clean than Slow

One of the most common complaints sounds like, “Argh! My Mac has turned so slow! I can’t stand dealing with this ‘turtle’ any longer! How can I solve this problem?!” Most probably, some users don’t even understand the source of the problem. They start blaming Apple developers and their own children who used to play several innocent games on the parent's device.

In reality, the most common cause is the overloaded hard drive. How can a user overload it? Well, each time you download large files like videos or games and forget to get rid of them once you’re done, your disk storage gets slowly filled. Once it’s fed up, the user starts experiencing a certain level of discomfort associated with the sluggish performance.

Luckily for you, there are a number of ways you can speed up your Mac again.

 

It may be dangerous to engage in any maintenance for the first time. If you are not an IT guru, any expert will urge you to take caution and back up your data. If you don’t want to mess up with another device (e.g., external drive) detect and delete useless items like duplicate files. Believe it or not, but your iTunes, Library, and some other locations/apps are full of that junk.

C’mon, it is rather simple: just grab an external drive and launch one of the native Mac utilities known as Time Machine. Then, you may proceed.

One thing to understand before moving to the list of the acceptable cleaning methods: there is no such thing as the best way to clean Mac. The users choose the cleaning method based on their own preferences.

What the 'Optimize Storage' Feature Is All About

People who have switched to macOS Sierra or High Sierra are pretty lucky: they only need to take advantage of the new function called Optimize Storage. This feature alone can:

Activate the Store in iCloud option

Delete iTunes videos the user has already enjoyed

Make the Trash empty automatically

Decrease clutter, which is the result of huge files/downloads

In case you are the owner of a Mac laptop with flash storage, this option is really precious. Why? The thing is, because of the design peculiarities, laptop users have less disk space at their disposal than desktop users. Anyway, cleaning your Mac’s hard drive is far more popular than replacing the existing hard drive with an SSD. The second option is just too costly for some people.

It is recommended to start with tossing away the junk from your hard drive. A data cleanup procedure can add an amazing share of space. Fortunately, there are many ways how a user can free up the disk storage even without some special expertise.

3 Methods to Erase the External Hard Drive on Mac

External hard drive is a perfect solution once you wish to clean up the native hard drive by moving some files to the external one. However, one day you may face the situation when the external hard drive gets messy, too. Basically, the steps recommended to clean up hard drive works for the external disk as well. Have a look at the top preferred methods.

Disk Utility

Onboard Mac utilities can do a lot, and they are free of charge. Connect the target drive to the Apple computer. Check whether the device detects the drive.

Move this direction: Applications à Utilities à Disk Utility

Select the Erase tab

Choose the disk/volume in the list on the left panel

Pick a file system to which you would like to format the external drive. For instance, those who wish to format a flash drive tend to choose FAT32

Click on the Security Options (unavailable for SSD)

Then, mention how safely you would like to clean the external drive (Most Secure is the top solution for those who fear any errors)

Press Erase to go on

Terminal

Let’s imagine the situation in which Disk Utility fails to complete the mission. Command Line is an alternate option. More experienced Mac owners may try taking these steps:

Find Terminal via Spotlight

Launch Terminal and type: diskutil list

Discover a list of disks to detect the target one via the disk identifier. Jot down the data

Enter diskutil eraseDisk JHFS+ (diskname diskidentifier)

Push Enter and to free up the external drive

Done!

Third-party Applications

To minimize your efforts, get a third-party software. Such applications can work with any types of drives including hard drives and flash drives. It offers the following features necessary to refresh your disk:

Cleaning drives from garbage automatically

Ejecting all external drives in a single click

Fast monitoring of free space on the drives

Outro

As you can see, wiping the hard drive, as well as the external storage or flash card, can be simple on a Mac. Each of the three techniques mentioned above has its benefits. The main thing you should always remember is to back up your data no matter what level of technical background you have. Then, let your Terminal, Disk Utility or the third-party app do the rest of the job for you!
