General Maintenance Tips

• Perform Time Machine backups to prevent data loss
• Upgrade the operating system to the latest version
• Keep your software up-to-date in the App Store and elsewhere
• Reboot the machine regularly (once per week is good)
• Delete stale wireless preferred networks in Network Preferences. NOTE: If you use iCloud Keychain, any wireless networks you have connected to, on any Apple device also connected to iCloud Keychain, will appear in the list of preferred networks.
• Zap the PRAM (also called NVRAM)
  • Reboot, then hold command-option-P-R until you hear the chime twice
• Boot into Safe Mode by holding Shift during the startup chime
  • This will clear the Mac's cache files; just log in (twice if you have FileVault turned on), and then restart once more
• Install anti-virus software (we use Sophos at RCS)
• Review the Trash and empty it
• Review contents of Downloads folder and delete files that you don't need

Browser Fixes

• Chrome Task Manager - like the Activity Monitor, but for Chrome (if you use Chrome)
• Check browser extensions / add-ons - running a lot of them can slow down your browsing
• Clear your browser (especially Chrome) - history, cache, passwords - these things can dramatically speed up Chrome
• Restart your browser - especially after clearing things above
• Reset your browser - this is a last-case fix, so come discuss with the Tech Dept before doing this
