CleanMyMac - I use CleanMyMac to clean my Mac. It works well and looks nice and I haven’t seen anything better so I use it. It scans your system for stuff it doesn’t need like extra language files or old caches or even big files that haven’t been used in a while and then lets you decide if you want to go ahead and delete them. It also monitors the trash and if you move an app you don’t need anymore to the trash CleanMyMac will ask if you want to delete any associated files also (Yes, yes you do.). It is free to try and $39.95 to purchase. They have a CleanMyPC for the same price.
Audio and Video
Lightroom - Lightroom is my photo editor of choice. It’s not cheap, especially when you have a free option like iPhoto or the upcoming Photos app from Apple, but it is made for professional photographers. Lightroom lets you do just about anything you can possibly do to photo files. Don’t buy it directly from Adobe, though. They’re going to try to rope you into a Creative Cloud subscription that will run you $10/month… forever. If you buy it from Amazon it will run you less than $150 and you’ll be able to download the standalone version right away.
Exposure - Exposure from Alien Skin runs either as a companion to Lightroom or as a standalone app. Basically it lets you emulate films and other photographic processes in your digital photographs. It’s not an essential app for most people but it does work really well and I love the results I get with it. It normally runs $149 but if you follow the more popular Lightroom and photography sites you can sometimes find really good deals on Exposure. I paid less than $100 for my copy.
Pixelmator - I would call Pixelmatr the poor man’s Photoshop but it’s way more capable than that implies. At only $30 it’s super convenient if you’re like me and only need a Photoshop-type app every once in a while for small jobs. For example, I made every one of our Podcast logos in Pixelmator.
Audio Hijack - Audio Hijack is one of those great utilities that does one thing so well that you end up finding a million ways to use it. Brandon and I use it to record ourselves for the podcast but you can also use it to record any audio that comes into your Mac. I’ve pulled songs off YouTube (shh, don’t tell anyone) and grabbed audio clips from movies to use in the podcast. I’ve even used it to set recording levels on the mixer I got for the podcast. If you do anything with audio you should probably have Audio Hijack on your Mac.
Logic Pro X - Ok, you almost definitely do not need Logic Pro X for making a podcast. You can do most of what you need to do in Garageband. But, having used Garageband, and now Logic, I can say that it is definitely worth the $199 to upgrade to Logic. It gives so much more control over every aspect of recording, editing, and encoding a podcast audio file. Sure, it’s expensive and there is a fairly steep learning curve but Logic is a great program and it makes my life easier.
Fission - Fission is by the same folks who make Audio Hijack and it is also a very useful app. I use it to trim and fade in/out audio clips I record in Audio Hijack. It also has a batch converter function that I use to convert audio files between formats.
Handbrake - Handbrake is billed as a converter for video but if we’re being completely honest most people only use it for one thing: ripping movies from DVD to a computer. It works great for that. There are a ton of different finicky settings and parameters in Handbrake but the built-in presets usually work well. And the best part of Handbrake is that it’s free.
MetaMovie - Once I have a movie ripped from a DVD and on my computer I use MetaMovie to add cover artwork and all of the metadata to the file. With MetaMovie you can search internet databases quickly for artwork, metadata, and chapter info then have all of that encoded in the file. After that you can import into iTunes and the data and artwork will show up anywhere you view the file: iOS devices, Apple TV, etc.
Skype - I’ll be honest, I don’t like Skype. But it’s free and it works. Brandon and I use it to talk to each other during our podcast recording sessions. I also sometimes use it to talk to family when we or they are away on vacation, especially when wifi is cheaper than roaming.
Twitterrific - Twitterrific on the Mac isn’t great. It’s in need of some serious updating but Twitterrific on iOS is my preferred client and Icon Factory are working on a new Mac version.
Reeder - My favorite RSS reader on the Mac (I use Unread on iOS). It works great.
Chrome - For those times when Safari isn’t supported. Or if you just need to open a page in a second browser.
Ulysses - Ulysses is my preferred writing environment on the Mac. I’m writing these very words in Ulysses. And it has iCloud integration and a great iPad app as well. It’s very customizable without being too technical (such as BBEdit).
Other Useful Apps
Droplr - Droplr is my url shortener of choice. If you follow me on twitter you have seen me share links and images and gifs with Droplr.
SystemPal - System pal monitors your Mac’s system. I use it for the CPU temp monitor that I keep in the menu bar.
Fantastical - I use Fantastical to manage events on all of my devices, Mac and iOS. My wife and I currently have eight different calendars in iCloud and Fantastical makes it super easy. It was one one of the first calendar apps to have natural language processing for inputing events and that really reduces friction in entry.
1Password - 1Password is the best way to organize any information you want safe and secure. I put passwords, credit cards, identification info, secure notes, etc., in there. You just remember the one master password and everything is accessible. 1P is available for Mac, iOS, Windows, and Android so you have no excuse not to secure your info. Seriously. Do it.
TextExpander - This is a very useful little app that lets you have custom text snippets triggered but custom text strings. For instance, when I type “addy” on my Mac it automagically expands to my email address. I also use it for html markup and fixing my common typos. They have an iOS version, too, but I usually just use the keyboard shortcuts in the settings menu for that.
Deliveries - Deliveries is my package tracker of choice on Mac and iOS. It works great and syncs between devices.
Wunderlist - My wife and I use Wanderlist to organize our projects and to-dos. It works great for us because it syncs and we can share lists (or choose not to share lists). And having Mac and iOS apps makes it easy to enter and keep track of tasks.
PDFpen - I use PDFpen for signing digital documents and for joining scanned bills into a single pdf for archiving each month. It works great for both although it does a lot more that I don’t really use it for.
Soulver - The best way I can describe Soulver is a cross between a spreadsheet and a scratchpad. It’s a great way to quick math and it’s another one of those programs that you find a million uses for after you start using it.
These are the Apple apps I use on a regular basis. They’re all free and likely already on your machine so I’m not going to link to them.
Mail - I know a lot of people hate Apple’s Mail app but it works fine for me. I don’t get all that much email, though, to be honest.
iPhoto - I use iPhoto purely because it lets me save all of my iPhone photos automagically through iCloud. I very rarely use it for any editing. It’s going to be replaced by the new Photos app this Spring which looks to be much more capable so I may use that more.
Safari - I use Safari as my primary browser. Firefox is kind of garbage now and as fast as Chrome is giving Google any information about my browsing gives me the creeps. Plus, if you use Safari on iOS it syncs bookmarks and tabs really easily.
Image Capture - Most people probably don’t know that Image Capture is even on their Mac. But it’s there, hiding in the Applications folder. If you need to import images or video from any device connected to your Mac but don’t necessarily want those files to go into iPhoto or iTunes use Image Capture to simply import the files and put them where you want them. Very handy when you’re on vacation and just need to batch import images to free up SD card space without having to edit in a full application.
Audio MIDI Setup - If you have any issues setting up audio input or output devices – very common if you’re doing a podcast – this is a great place to start fixing them. You can choose which devices are used for input and output as well as setting levels for those devices. It does what the System Preferences > Sound pane does but so much more.
There you have it. A ton of apps that I pretty much have to have installed on my Mac to make everything work the way I want.
