Here are some great tips I collected from all over the Internet to make more space on my Mac and free the computer from junk data. I went through all of them and my Mac appears to be faster and runs more stable. Learn here how to gain more space on your Mac.
Part I: Find the space eater and delete them
If your hard drive is rand full try to find the files you don’t need anymore.
1. Clean up your program folder
If you always use the same browser you don’t need another one – so go ahead and delete programs which have the same function. Also – if you have installed Thunderbird or Entourage you can delete them when you use Apple’s Mail program. If you are like me and you often try out new programs on your computer you might have programs in your application folder you don’t need anymore. Put them into your waist bin (if you use this as a checklist please read first until the end because I found some programs which clean all files which belong to a program)
2. Delete your ZIP- and RAR Archives
A zip file is like a container which stores folders and compress them to a smaller file. Once you have unpacked your zip-file you no longer need the zip file. If you don’t use Safari (which does it automatically) you keep the zip file and have a duplicate folder on your computer. To find all your zip files add .zip into Spotlight on top right and you can see all zip files on your computer. Throw those you don’t need anymore into the waist bin.
3. Delete old Driver
When you get a new printer the driver from your old printer most probably stays on your computer. You can delete your old printer software in your application folder but make sure that you also delete all the utilities coming with it.
4. Get rid of the DMG files
When you install software it often comes as a DMG file. After installing the software you do not need the DMG file anymore – just if you want to reinstall the software. A good idea is to burn all your DMG files on a DVD or put it on a USB stick so you can access it when you have to re-install your computer. Again, to find the DMG files click on the little magnifier on top right of your desktop and enter .dmg and all your programs will be listed and you can delete them if you have made a backup on your computer.
5. Clean up your Mail Program
If you use Apple’s Mail program emails with attachment for example are stored up to three times – in your mailbox, a copy in loaded mail-objects and if you save the file yourself most probably also in your download folder. To get rid of these double and triple savings go to Mail –> Preferences –> Accounts –> Mailbox Behavior.
6. Delete old Podcasts
ITunes is a playground where you can find tons of free audio- and video podcasts. If you have set the download of new podcasts to automatic then you might not be able to listen to the files as quick as they appear. When you want to unsubscribe from a subscription go to iTunes and click on the left side on “Podcasts”. On the bottom you see the button “unsubscribe”. You can also delete episodes there you don’t need anymore.
7. Delete Cache
Content which has already been loaded from the Internet are saved in Cache. If you need the content again, the Mac compares the cache content with the website. With time Safari stores a big amount of data. Therefore it is good to delete the cache from time to time. Go to Safari –> Empty Cache. It might take a while, depending on the amount of data stored there.
8. Delete foreign dictionaries
Because the Mac OS application is created for users all over the world lots of languages are included. Go to Library –> Dictionary and locate the three files called Shogakukan. If you don’t need japan dictionaries you can delete those files.
9. Delete old iOS Backups
If you use the iPhone, iPad or iPod touch your Mac regularly synchronizes with your iOS devices. Those backups are stored on your computer. You can delete the backups you don’t need anymore. Go to iTunes, Preferences and devices to delete old Backups.
10. Delete not-needed Screensaver
Screensavers with complex animations use lots of space on your hard drive. You can delete those when you go to Library –> Screensavers. Delete screensavers you don’t need with drag and drop into the waist bin.
Of course you can check more folders, e.g. your Movie Folder or delete unsharp or no longer needed photos and old music from your library.
