MacOS settings for security and productivity (updated 2020)

MacOS settings for security and productivity

I was pretty impressed that my previous OSX install had served me for 4 years of heavy software development and daily personal use.

But a time has come for a fresh system reinstall. During the setup, I had some troubles remembering all useful system settings and tweaks I’ve made, so here’s the list for my future reference, and possible use for other power users.

Apps

Utility Apps

  • Karabinier - a tool for remapping keys
    • Replace CapsLock with ESC
    • Switch right command with right alt (for easier access to polish diacritic chars)
  • Alfred (free or $25) - application launcher and a swiss army knife
    • Bind CMD + F1, CMD + F2, etc. to app activate, my most used apps are Chrome, MacVim, and iTerm
    • Add a task to task manager’s inbox, e.g. inbox Buy milk
    • Some custom scripts, e.g. j GR-123"command to open Jira ticket
  • Spectacle - simple window manager, organize windows using keyboard
  • KeepingYouAwake - puts a coffee cup icon on the menu bar, clicking it prevents your Mac from going to sleep for an hour (modern version of Caffeine app)
  • Flux - prevents your eyes from being burned in late hours
  • MenuMeters
    • displays system metrics (CPU, memory, network, disk usage) on menu bar
    • quickly identify anomalies like zombie apps taking 100% of CPU power
  • MonitorControl - software controls for monitor brightness
  • BetterTouchtool - customize TouchBar icons
  • UnnaturalScrollWheels - automatically enable “Natural” mouse scrolling on Apple Mouse and disable it for other mouses

Security Apps

  • 1Password ($65 or $3/month) - fully featured and good looking password manager
  • ClamXav ($30) - open-source antivirus, useful for scanning apps from not trusted sources
  • LittleSnitch ($30) - firewall, it requires you to set rules for any new Internet connections
    • Detect suspicious connections
    • Block unnecessary analytics/tracking connections
  • GPG Suite - GUI tools making using GPG email and files encryption easy, integrates with Mail.app
  • Chrome with my favorite plugins:
    • Disconnect - disables tracking/analytics/ad-network scripts
    • uBlock Origin - best ad-blocking tool
    • Bookolio - displays a nice list of bookmarks in empty tabs, I like it better than having the bookmarks bar always visible
