Over the years I learned to share things. Switching my OS to the fruity company, back in 2015 (so by now running macos 4 years, daily), I was looking at what tools and utilities could make myself productive (read: to stay in focus and not get annoyed by stuff caused by the operating system)
Probably this is a habit I got from the previous 6 years of running Ubuntu on a daily basis, where OSS taught me to look to fix things, or search for solutions (or utilities).
Below, you have my list of apps (free or not !) that I find useful to my daily activities (beside other regular business related ones, that's another story). I'm also adding some comments and I won't link sites, you'll have to search for their names on Google v2.0 in order to check them out.
If you don't know what the comment is saying ... not my problem :) Some of these are payable, but not excessive (I'm cheap), so in an alphabetical order, here they are:
1password - you do use a password manager, right ? I also had LastPass, but for the moment I think this is the best. As alternative (free), you might look at Bitwarden.
Alfred - better spotlight.
AppCleaner - for app remainings after uninstalls.
Apple Music - something has to sing when focusing on stuff.
BetterSnapTool - window resizing on macos made easier.
Boom2 (or Boom 3D) - sound enhancer, nice to boost an already good sound on mac.
CudaText - nice editor.
DaisyDisk - cruncher for what takes that space.
draw.io - diagrams, sharable with teams via SCM (read git, these days).
Eclipse - coding, but for me it's mostly looking, these days...
Github Desktop - go figure ..., terminal just as good, but hey ...
iTerm - life in terminal is fun, sometimes.
LightShot Screenshot - consider Retina oversized screenshots, and default Cmd-Shift-Ctrl-4 not enough when you want to send it to other humans using PCs.
MacPorts - alternative to Brew ... :)
RDM - nifty utility to change resolution on my screen, depends if I have my glasses on ... or not :)
Quiver - note taker. And SimpleNote, and Google Keep.
SimpleMind - mind mapper.
TinkerTool - tweaking more macos settings.
VSCode - another coding IDE.
If this list will change, I will update this post, but the reason I publish it is my feeling that now I have a system on which I no longer have annoyances (well, after 5 years of mocking apps and crunching the net).
