Mac: Hazel has long been our favourite tool for automating file cleanup on your Mac, and today it's getting a little easier to use with live previews and support for syncing services. Hazel's main purpose is to make it easy to automatically organise your files. Think of it like IFTTT, but just for files on your computer. You can set up rules to automate sending files to specific folders, like sending all new MOV files from the Downloads folder to a Movies folder. This is great, but it can also get really complicated really fast. The new live preview system makes it so you can see how those rules work in real time. Click the Preview button, and you get a look at how your rule works. It's a small thing, but it makes Hazel a lot easier to wrap your mind around, especially if you're new to the software. You can also now click the eye icon to see what a rule has done in the past, which makes troubleshooting much easier as well. Also new is syncing, so you can run Hazel rules on multiple Macs, and the ability to watch Smart Folders, which is nice if you're already using Finder's built-in system for organising files.
Hazel 4 now requires Yosemite or later. Existing users can upgrade for $US10 ($13), but if you purchased Hazel after 6 September 2015, you'll get the upgrade for free. You can also check out a free trial if you're curious about it.
