Speaking of apps we cannot do without, I’ve been using Eagle for the past few months (don’t get it confused with EagleFiler). I discovered this app purely by accident.
Although it’s being touted as an image organizer, it also works beautifully to store and organize all your documents. It’s a perfect place to keep your bills, receipts, notes, etc. About the only drawback is it does not have an iOS version. But they’re supposedly working on it.
While currently working on a fairly big project I’ve re-discovered Things. It’s expensive - and you have to pay 3 times for Mac, iPad and iPhone - but there’s a simple elegance about it that just works. I’ve tried using Apple’s Reminders but we just don’t get along.
I wouldn’t say Things would be the first app I’d install on a new Mac, but for the way I’m using it, it’s been extremely helpful.
There are a couple of apps that I typically install on new personal machines. I’ll mention Snagit in particular. It’s marketed as a screen capture/recording app, but I mostly use it to annotate screenshots and other PNG/JPG files. I find that it is a super convenient and fast way to mark up images with arrows, borders, text, and so on. I use it several times a week without fail.
