Delete the Duplicates

Having your Mac for a while and using it for the longest time, it is likely that you’ve placed a lot of files in it. With all the available options made to us, duplicate files have a high chance of occupying some much-needed disk space.

Maybe the duplicate is a movie, a song, a photo, or something else, but one way or another you don’t need them and you should hunt them down, then delete them permanently. For example, you can delete duplicates in iTunes to save some space.

Clear Out the Trash Bin

Much like when you have to take the trash, you have to make sure that you clear out your trash bin every so often.

Otherwise, even though the files are not in their original locations, they are still taking up some very important disk space. Only when you clear out the trash bin, that’s the only time when they are officially removed from your Mac.

Uninstall Unused Applications and Programs

Uninstall useless apps is an efficient way on how to clear disk space on Mac. Much like clearing out the trash bin, if apps and programs are just sitting around and taking up some disk space, you might as well uninstall them.

That way you can not only get back the disk space you need, you could also be saving on processing power as a number of programs and apps update in the background, which could also be one of the main reasons why your Mac is slowing down.

As mentioned earlier, however, if your primary method of uninstalling is dragging the program into the trash bin and deleting it, this option leaves a lot to be desired for, so you may want to explore other ways of uninstalling if you really want to maximize getting back your disk space.

iTunes is a handy little program that comes with most Macs. Most users tend to use it and store videos, music, and other items, while that’s great and all, iTunes tends to back up automatically from time-to-time.

Remove Old iOS Backups

Considering the age of your Mac, it is more than likely that you’ve updated your iOS a few times over. It is also possible that a backup of the older iOS systems might still be sitting around on your Mac.

Scan through your Mac, assuming you are sure that you will never ever need them and delete them as soon as you are sure of your decision. Getting rid of those files will once again free some more disk space and if you updated your iOS a few times over, it could be rather large files.

Clear Out Temporary Files

You are welcome to find all of them one by one, but to be honest, a lot of cleaners can really make your life a lot easier with a few clicks here and there.

Clean Out the Download Folder

One of the folders that can really snowball into a space-consuming monster is the download folder. Some people tend to download a lot of files and just leave it in the folder, sometimes they only use the file once or twice and leave it in the download folder for a long time, forgetting it’s even there.

The suggestion is to maintain your download folder daily, delete what you don’t need and move files you need to other files, it takes a little bit of time, but in the long run, at least you won’t have to spend a day or two sifting through your download folder.
