10 awesome most have freeware for your Mac
Vanilla
Vanilla hides certain status bar icons that you don’t wish to display all the time. It’s very useful for keeping your status area clean, as well as allows you to move around any of the status icons around the upper dock.
CleanMyMac
While I mainly use it to delete temporary files, CleanMyMac has a suite of tools that keeps your Mac running like it was brand new. It’s also got a brilliantly clean UI.
Magnet
Okay, kind of a joke tool, but definitely worth the value. Magnet is basically just a recreation of Window’s “snap” tool, which allows you to snap windows or apps to certain portions of the screen. Makes it a lot easier for organizing multiple windows on any single desktop screen.
Spectacle – window management tool.
Wine – to run .exe program.
Helium – a floating browser window
Franz – messaging app
f.lux – it makes the color of your computer’s display adapt to the time of day
Airtable – Calendar and table Ap at the same time
Bubble Browser – Organizing Notes from Evernote
