1. Tidy up your desktop
Last year I discovered Light Pillar’s wonderful app Desktop Tidy. This handy utility cleans up your Mac’s desktop, keeping it free of clutter. It stores all desktop files and folders in a hidden Shadow Desktop, which you can access from the menu bar or in the Finder. That way, every file I download, each screenshot I capture, and every image I drag and drop to my desktop is stored and filed in an easy-to-reach location. The utility quietly works its magic at scheduled intervals – as often as every minute or as infrequently as every seven days. It even organises desktop items by file type, which makes finding and renaming files easy. – Leah Yamshon
2. Delete unnecessary disk images
For most people, the Downloads folder is a dumping ground where files pile up in forgotten heaps. Go to the Downloads folder in the Finder and type
disk image into the search box. Select Disk Image under the Kinds header. Now, delete all of those downloaded DMG files that are just taking up space! – Jason Snell
3. Empty out space-hogging Mail Downloads
As part of my job, I get quite a few attachments via email – PDFs, ePub ebooks, Word documents, images, you name it. Most of the time I save those files to my desktop or my Downloads folder, but on occasion I make the mistake of double-clicking a file. When you do that, the document saves itself to your Mail Downloads folder, hidden away in your Library file. Double-click enough files, and that folder can balloon in size. That’s why I make sure to check it and empty it every year or so.
The easiest way I find to do this is to use Spotlight – press Command-Space to see a search field appear – and then type
Mail Downloads. Click the Top Hit, which should be the Mail Downloads Data folder. If this isn’t working for you, try getting to it the long way. In the Finder, select Go > Go to Folder. Type
~/Library/Containers/com.apple.mail/Data/Library/Mail Downloads in the text field.
Click Go, and a Finder window will open showing the Mail Downloads folder.
4. Keep a clean cache
We’ve all heard “Empty your cache” as a web browser troubleshooting tip. As it turns out, a Mac stores lots of information – not just browser-related details – in files called caches, allowing quick access to that data and reducing the need to fetch it from the original source again. Unfortunately, that information can sometimes become corrupted, or otherwise problematic – for example, you might end up looking at old data instead of the most current version of a website, or you may notice that a file’s icon doesn’t look quite right in the Finder.
~/Library/Cachesis a good place to start), plenty of tools will handle this job for you. Cocktail, from Maintain, is among the longest-running and best of these. Not only can it clear your caches, but it can also perform assorted other maintenance tasks, such as deleting your browser’s cookies, looking for corrupted preference files, rebuilding certain databases and way more. You can download it and use it for free for up to 10 launches, but at just under US$20, it’s a pretty good buy. – Dan Moren
