Open source software is also the foundation to many of today’s largest, most renowned software packages – without open source software we might not have the amazing, mind-blowing applications and software packages we use everyday. In light of this, I have compiled a list of 30 of the best open source applications for Mac.

1. Open Source Disk Cleaner

Cleaning up anything seems a very laborious task.

I remember how my mother used to bellow at me to clean my room.

But..

..I always had some lame excuse to keep this task at bay.

But unlike then, now it’s totally opposite with me.

Now that I use MacBook, I’m in constant scour for good cleaners for my device.

Keeping the computers and phones clean are not only important to free up space, but it also keeps them safe from Malware and viruses.

Being an Apple products aficionado, and to keep them in good condition, I’ve been using many cleaning apps for my iPhone and MacBook.

I’m listing some of the free Mac Cleaning Softwares and applications for you guys out there who have clogged up PCs and need some memory.

#1: AppCleaner

One of the easiest to use Cleaner of all is AppCleaner.

What you have to do in this application is to just to drag and drop the app that you want to uninstall.

AppCleaner waves its magic wand in two ways.

You can either drop the files manually into the app’s window

or..

..just use the smart delete feature of the app and it will automatically find the files or the data of the deleted files from the trash.

#2: Dr. Cleaner

If you want to speed up and optimize your Mac with just a click then this great app named Dr. Cleaner is just for you.

It cleans your Mac’s disk and frees up a lot of space thus enhancing its performance.

It not only deletes the unwanted files but also eradicates the cache files that are building over a period.

This app is a boon for the amateur Mac users and what else can one ask for but a free app and here you’re served with one.

#3: CCleaner

Want to give your Mac a new kick?

Then you should give a chance to CCleaner.

It’s an effective and simple to use app that makes the Macs fast without touching the privacy of your files.

In fact, it is designed to make the device more secure.

It has three elements - Cleaner, Tools and Options.

These elements remove the junk files, uninstall the programs and fixes or deletes the cookies respectively.

Its paid version has lots of other features

but..

if you just want the basics, then you should go for the free one.

Why do you let your pretty Mac get cluttered with junk?

MacClean 3 cleans and frees your Mac’s hard drive with zero effort.

It works on the rule of three - Select, Scan and Clean.

It deletes all types of junk, for instance, Internet Junk, System junk, Development Junk etc.

It provides 10 different tools to clean your Mac’s unwanted things totally.

#5: Magican

If you think that buying a Mac frees you from every responsibility of making efforts in maintaining it, then you’re wrong my friend.

Just because the device seems to be working fine doesn’t mean that it don’t need any repair or maintenance.

An optimizer tool, Magican cleans the hard drive of the device from every unnecessary caches and data.

It keeps a check on the status of the system by showing CPU usage and Disk info.

It goes deeply into the stats, which is according to me an efficient feature.

It has been a very successful app since much time and now can also be supported by OS X 10.10 Yosemite.
