How to fix slow performance on a Mac

1. Restart Your Mac

  • Restarting can clear temporary files and refresh system resources.
  • Click on the Apple menu () > “Restart…” > Confirm by clicking “Restart”.

2. Check Activity Monitor

  • Activity Monitor can help you identify resource-hogging processes.
  • Go to Applications > Utilities > Activity Monitor.
  • Check the CPU and Memory tabs for any processes consuming a high percentage of resources.
  • Select these processes and click the “X” button to quit them if they are not critical.

3. Free Up Disk Space

  • Low disk space can significantly slow down your Mac.
  • Click on the Apple menu () > “About This Mac” > “Storage”.
  • Identify large files and applications you no longer need and delete them.
  • Empty the Trash to free up space.

4. Manage Startup Items

  • Too many startup items can slow down your Mac’s boot time.
  • Go to the Apple menu () > “System Settings” > “Users & Groups”.
  • Select your user account and click “Login Items”.
  • Select any unnecessary items and click the “-” (minus) button to remove them.

5. Update macOS and Applications

  • Updates can include performance improvements and bug fixes.
  • Go to the Apple menu () > “System Settings” > “Software Update”.
  • If an update is available, click “Update Now”.
  • Also, update your applications via the App Store or the applications’ own update mechanisms.

6. Clear Cache Files

  • Accumulated cache files can slow down your system.
  • Go to Finder > “Go” menu > “Go to Folder…” and type ~/Library/Caches.
  • Delete cache files from within this folder (note: do not delete the entire folder, just its contents).
  • Repeat the process for /Library/Caches (you might need administrator access).

7. Check for Malware and Adware

  • Malware and adware can affect performance.
  • Consider using reputable antivirus or anti-malware software to scan and remove any threats.
  • Malwarebytes is a popular option for Mac.

8. Reset SMC and NVRAM

  • Reset SMC:
    • Shut down your Mac.
    • For laptops with non-removable batteries: Press and hold Shift + Control + Option on the left side of the keyboard, then press and hold the power button for 10 seconds. Release all keys, then press the power button to turn on your Mac.
    • For desktop Macs: Unplug the power cord, wait 15 seconds, plug it back in, wait 5 seconds, then turn on your Mac.
  • Reset NVRAM:
    • Shut down your Mac.
    • Turn it on and immediately press and hold Option + Command + P + R.
    • Release the keys after about 20 seconds, or when you hear the startup sound for the second time.

Several tools for observing screen pixels’ transition times

One of the main parameters in choosing a monitor is the transition times of the pixels from one color to another. The subject was and is intensively addressed, but now we have the opportunity to easily refer to a measuring tool, or more precisely to a common scenario: the tests offered by blurbusters.

Blurbusters are distinguished by the popularization of important terminologies for measuring the “clarity of the moving image”, which of course depends on the technology of the screen used. At the moment these are not of interest but only the knowledge of the tools made available by them.

An example would be the famous “testufo” test: https://www.testufo.com.
