So you’ve had your Mac for a while, and things don’t feel as fresh and clean as they used to? Although Macs don’t require a lot of maintenance for cleaning, those temporary files, app leftovers, and system cache do accumulate. These files may slow down your machine and take up a lot of valuable space. In this article, we share quick and easy ways to clean up your MacBook. Let’s get started!
How to clean your Mac automatically
Here’s a simple diagram to explain the most common types of computer junk, sorted by size. Some of these, like Trash bin files, are easily reachable, while others are stored away in hidden system folders. Sadly, there’s no easy way to clear them up without special skills.
If you don’t feel like spending the next several hours cleaning your Mac manually, you can use a powerful cleaning tool CleanMyMac X to find and remove all the clutter your Mac contains. It knows which files are useless, how to find them and remove completely. CleanMyMac has everything to finish the 3-hour task of a Mac cleanup in under 5 minutes.

Done! Now your Mac looks much better!
How to Clean Mac Hard Drive Manually
If you never performed an automatic or manual system cleaning — it means that your Mac has been collecting unnecessary files and clutter for years. You can quickly clean up your Mac with these easy steps.
1. Clean up cache
You’ve probably heard “Remove your cache” as a web browser troubleshooting tip. In fact, your Mac stores a lot of information in files called caches, allowing fast access to that data and reducing the need to get it from the original source again. Unfortunately, those files take a lot of space on your Mac, and instead of speeding the things up, they slow your computer down. Therefore, if you want to give your system a boost, clean your Mac from the cache files.
There are two ways to do that: you can delete them manually or use a MacBook cleaner like CleanMyMac X to do the job for you. Of course, the second way is an easy and fast one. However, if you decide to clean up the cache manually, check out a comprehensive guide on “How to Clear Cache on a Mac.”
2. Uninstall apps you don’t use
The applications you’ve installed on your Mac take up space, of course. And over time when your Mac becomes full of different apps, it may start running slowly. How to clean MacBook? In the first place, you need to remove the apps you no longer use or need. To do this, right-click on the app you want to remove and choose Move to Bin.
You may be surprised to find out that sending an app to the Trash will not uninstall it completely because the app leftovers still remain on your Mac taking up a lot of storage. So, if you want to be a responsible Mac user, you need to uninstall applications the right way. Here’s a step-by-step guide on “How to Uninstall Apps on a Mac.”
Extra step: Trim down your login items
Login items are applications that run automatically upon startup. Nowadays, every second app tries to become as prominent as possible and get into your Login Items. First of all, you may not even know what they are (not all of them appear in the Dock). Secondly, such apps consume memory. That's enough reasons to get rid of extra login items you don't need.
- Open System Preferences.
- Go to Users & Groups.
- Choose your nickname on the right.
- Choose the Login Items tab.
- Check startup programs you want to remove.
- Press the “–” sign below.
You’re done.
3. Clean out useless duplicates
Identical photos, music tracks you’ve added one time too many, saved and re-saved PDF files… all of that sits on your Mac and gobbles up storage. The storage that could be used for better purposes.
So how do you quickly weed them out? The fastest way is to use Gemini 2: The Duplicate Cleaner.
- Download and launch the app
- Click “Scan for Duplicates”, and watch as it quickly fetches them from different corners of your Mac.
- Once the scan is done, hit Review Results and check which copies you want to remove.
- Click Smart Cleanup to delete everything you’ve selected.
That's it. Now your Mac should be completely duplicate-free.
4. Empty the trash
Even though you’ve deleted the files, they reside in your Trash bin taking up a lot of storage on your Mac. They are just waiting to be removed completely. If you want your precious hard drive space back, you need to empty the Trash.
Here’s how to clean your MacBook from the trash:
- Click and hold on the Trash can icon in the Dock.
- Click Empty and then Empty Bin.
The process is quite simple, right? There is even a more effortless way to clear Trash. CleanMyMac X scans your Mac for junk and lets you remove all trashed files. To do that, launch CleanMyMac X and press Scan. When the scan is completed, click Review Details to see what exactly CleanMyMac X has found.
I’ve already cleaned Bin a couple of weeks before, but over some time, almost a gigabyte of trashed files has accumulated. Now, I can simply click Back to Summary and then Run to clean Trash and system junk.
5. Reduce clutter
Apple has already thought about the clutter that can be generated on the Macs and provided a possible solution. Here’s how to reduce clutter on your Mac:
- Go to the Apple menu.
- Choose About This Mac and then Storage. Here you can see how much free space is left on your computer.
- Then click Manage.
Here’re some recommendations for saving space on your Mac. You can choose Review Files to examine apps, documents, and other files that are stored on your Mac.
You can choose any file in every category (Applications, Bin, Documents, etc.) and click Delete to remove it and optimize space. Look through other recommendations and make the necessary changes to use your Mac’s space more efficiently.
6. Delete large and old files
It has always been a rule of thumb among computer geeks, that you should keep a minimum of 15-20% of free space on your main hard drive. This is just a rough estimation, but the more free space you have, the faster your Mac works. A computer magazine once performed a test on this, which concluded that the difference in speed can reach as much as 35%. If you work with heavy graphics or video rendering, even more free space is recommended.
How to have more free space? Delete large and old files.
The first way is totally manual and requires you to find them one by one, while for the second way, you just need to make two clicks and CleanMyMac X will do the job for you.
How to clean up Mac with CleanMyMac X:
- Download CleanMyMac X (a link to a free edition of the app)
- Launch the program.
- Go to the Large and Old Files section on the menu.
- Click Scan.
- Review the details, select what to clean and then click Clean.
That’s it!
7. Remove old iOS backups
Having your files backed up is a wonderful thing. But over time your Mac becomes overloaded with old backups that take gigabytes of storage on your hard drive. That’s why you should consider removing the old iOS backups you no longer need.
Each backup remains stored on your computer and is accessible via iTunes. To delete the old backups, you need to do the following:
- Choose the Apple menu and then select About This Mac.
- Go to the Storage tab and click Manage.
- Here, choose iOS Files.
- Select the backup you want to remove and click Delete.
- Confirm and you’re done!
That’s it! The backup files are gone from your Mac forever.
8. Wipe out Language files
Unused language localizations take up about 1 GB of storage space. Mac applications come with language files for every language they support. It allows starting using the app in that language immediately. Cool, right? Not always. Just consider: when was the last time you used the app in Bengali or Korean? Since you don’t speak those languages, such files just waste space on your Mac. You need to remove the unnecessary language files and clean MacBook from that clutter.
How to delete the language files? Go to Finder > Applications, then right-click the app which language files you want to remove and choose Show Package Contents. Open the Resources folder and then find folders ending with “.lproj.” Every folder contains language files for one particular language. Note that for every app you should manually find and select the files to remove. But there is an automatic way to delete the language files that will save you tons of time — CleanMyMac X. Just download the application (for free) and it will do the job for you.
9. Delete old DMGs
Disk images (DMGs) often take up valuable space on your Mac. Here’s how to perform a Mac cleanup and get rid of those files:
- Open Finder and type “disk image” in the search bar.
- Then delete all files that have .dmg extensions. Don’t forget to remove them from Trash as well.
CleanMyMac X allows you to locate and delete DMGs quicker. With its System Junk module you can remove unused disk image in the single click of a button:
Just press Clean and it’s done!
10. Remove duplicates
Useless copies of your documents, files, and photos eat up your Mac’s precious space. Therefore, if you wonder how to clean up a Mac and boost its performance, try to delete the duplicates. Note that the process of finding and removing the duplicates requires either a lot of patience and time (if you decide to delete them manually) or a duplicate finder app. Whatever method you choose, make sure to check out this article on “How to Find Duplicates on Mac.”
11. Tidy up your desktop
Many people use Desktop as their primary destination for files. But this could be tricky because your OS treats every file on a desktop as an active window. When items on your desktop are too many, Finder gets substantially slower. This leads us to the most compelling advice in this article — cleaning up desktop does miracles!
Rather than just leaving every file on your desktop, organize them into folders. The latest macOS does that automatically thanks to the Stacks feature. You can also use Google Drive, Dropbox or any external storage device to save your files and keep your desktop tidy.
12. Clean your Mac’s keyboard
Our last but not least advice is to wipe your Mac’s keyboard. As you use your keyboard daily, it quickly gets dirty. Moreover, all those crumbs may live under the keys forever!
If you were wondering how to clean Mac’s keyboard, there are no special rules here. You can try blowing the dust and other particles out of your keyboard once in a while. Disinfecting wipes and alcohol-based sprays may also prove useful. Just choose the piece of fabric and wipe the keys gently to make them clean and shiny!
All in all, be careful with your system files. Don’t delete things you’re not sure about. If you are not completely confident that you can manage the task by yourself, better use a dedicated utility like CleanMyMac X to get a fresh and clean Mac in just two clicks. Here's the video describing quick tips to clean up your Mac:
Happy cleaning!

I will be purchasing a MAC Pro as soon as the release of Leopard comes out, so I am currently focusing on all the software and hardware that I want to get for my new MAC. I am currently a PC user and I have seen the light. I have been converted.
I have been looking at a Belkin UPS to use with the MAC Pro but from the tech specs I noticed that the MAC Pro has a max rating of 6A on 240V (what we have here in the Aus & in the UK). That's 1440watts. I can't seem to find a UPS that is that big, besides massive cabinets used in the corp. world.

For the numbers you provide the MacPro uses a max of 1440VA, to get watts you have to multiply the VA by the power factor of the MacPro (what ever it is).
The APC RS 1500VA ups is big enough.

I'd go for something like I used to use for my server: two 12v deep- cycle gel batterries of the maritime / emergency-services vehicle persuasion (car/truck batteries, but with substantially deeper Amperes and without the hazards of liquids) sealed in a small steel cabinet about two by one by one (h x w x d) feet, which also contained the rectifier and surge protection, and analog dials for current voltage and amperage readouts. Any recreational vehicle shop or battery- rebuilder can run one of these up from available stock; mine cost about one hundred and fifty dollars (US), and provided about 7 hours reserve power to my Proliant 3000, which only drew 700W max, about 1/2 the max wattage of your Mac Pro. This cost the same as the then (6 years ago) cheapest APC capable of supporting the Proliant's load, but provided several times that APC's power reserve and had a longer life- cycle, to boot. Mind, it wasn't light, at about 70 pounds! Don't forget to have the shop include ventilation louvers, as while the system does not generate much heat normally, the batteries will last longer if they are close to room temperature, and the heat generated when the system is active (power main down) is considerable. Mine supported that server through many winter ice-storms without flaw.

The 6 A rating is a maximum startup surge rating. There should be a maximum power supply wattage rating, this is more like what you need. But even this is going to be overkill as you are unlikely to ever pull that much power continuously.
A 500 VA UPS will probably work just fine for you. What is just as important is how long the UPS will power your system but that can be hard to get info on.

In my experience most blackouts are just brownouts and anything keeping the system up for 15 secs is perfect. If it's more than that then it could easily be much-much longer anyway and then nothing helps. All my computers are on UPSs and the system works, almost perfectly.
BTW, the batteries cost a fortune and they last only about 4 years [APC].

But when you do have a black out you need a UPS that will hold it up long enough for you to get to the computer (after finding a flashlight and tending to whatever else needs doing then) and close out whatever needs doing then shutdown.

I have found one by Eaton 'Powerware' here is OZ.
I think I will be going for the 9120 at 3000VA. Should give 30% spare for future.

The ideal solution is to have a UPS that is smart enough to tell the computer to shut itself down cleanly. This is one of the other major feature points in choosing a UPS.
For example, for my headless boxes at home I need a UPS that has a serial port, and speaks a protocol I can hack in order to hook a black out into a shutdown.

APC, Belkin and some other manufacturers have a USB port on their latest versions. They include Mac software (or you can download it) but you don't need it, OS X has support built in for it.
For a users workstation I'd prefer to do the shutdown myself if possible. Hence the desire for a longer hold up time. For a server automatic shutdown is fine.
