This is a click-bait title, but I know that this is something that I have looked at when I first started using the Mac platform daily for work over a year ago. I love finding the best applications out there for the job at hand. Many of these titles are my daily-drivers, and some I only use when needed. This is mostly suited to the Lamp Stack but many of these tools will help many people.
IDE
PHPSTORM – I love the IntelliJ platform, but I try to not drink the kool aid. Don’t be dogmatic, be pragmatic with the tools you use. This tool replaces multiples such as FileZilla and code merging tools.
MySQL
Sequel Pro – This is an amazingly simple tool that lets you jump into a DB way faster than Workbench. Let crashing too IMO.
Browser
Chrome – You can’t really bead Chrome’s Debugger, although I have a buddy at work that swears by Safari.
Other Tools
Flux – Be easier on your eyes.
XCode – This has an excellent file merge tool and helps with other development.
Unclutter – Amazing for Notes and Copying and Pasting
LastPass – It might get hacked someday, but for now, I trust my random passwords to be accessible across multiple platforms.
You can get a lot of these tools (and many more) installed easily with macapps.link.
