Junk files on Mac

Ditto to previous posters information.

To Add a bit of addition info below

Any Third Party Applications that will interfere with the normal operation of the OS,  is an invitation for disaster and comprise the Operating System

Certain Applications maybe available on the Apple Apps Store - this only means the Developer is prepared to pay Apple a portion on each sale.

What the Application may do to the computer is up to the User to check this out before purchase

Any of the below should be removed as per Developers Instructions 

1 - Disk Cleaner 

This will include CleanMyMac , 

MacKeeper,

Dr Cleaner Pro Plus

Open Cleaner one Pro

Macmechanic

Read some of the posting and arrive at your own conclusions.

Besides what to avoid here's what you should do:

It's good practice to reboot frequently, like every 2 days. This cleans out temporary system and application cache and swap files.

Also do an occasional (maybe once a month) boot into Safe Mode according to How to use safe mode on your Mac. Then reboot normally.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

You are welcome and thank you too

Spring Cleaning a bit early ?

Does the computer experience unusual behaviours like crashes for sudden crashes of applications ?

Does the computer present an alert of " Running Low on Space " ?

If none of the above, would suggest not looking for trouble as trouble will find you some enough.

Should the User ( you ) still want to do some cleaning perhaps we need to see the General Condition of the computer as it is now

Download the Application Etrecheck directly from the Developer.

This is a Diagnostic Tool that makes no changes to the computer.

It makes a coherent and readable inventory of both the Hardware and Software used on the computer 

The application is free or paid from added features. 

The Report will Not Reveal Any Personal Information. 

Post back the Full Report - copy and paste - >>>> using the Additional Text Icon ( 3rd Icon to last ) <<<<

We can have a look at the report for possible issues and may have possible suggestions to resolve the issues

Hi! So I need to clean junk files from my Mac. Caches, unused files from deleted programs(leftovers) and basically everything unused, temporary files so on... All unused files. Everything that is not needed. Should I use Mac cleaning third party software and which one? What is the best way to do this? Also I don't want to spend a lot of time on that so if it can be a faster way that would be appreciated.

Are you having an issue?

How would a third party app know what this files are(?)...

You are asking for trouble with third party apps along these lines— all known to cause issues on the macOS.

Welcome 😀

Should you decide to run the Etrecheck Application at a later time, do post the report and we ( collectively ) are more than willing to have a look 👀
