Chosen Solution

My laptop is working properly, but slow. Is it worth upgrading the SSD or should I get a new laptop?

Check to see the capacity of the drive. Next, do a “Force Quit”, and see how many programs are running in the background. Command, option, escape. These extras can be removed in your System Preference > Users > log in items

Here are some advices:

  1. Disable unnecessary service and heavy performance programs.
  2. Make sure there is enough free disk space, especially C drive.
  3. Defrag hard disk.
  4. Upgrade OS.
  5. Check and remove viruses and malware. If you’ve used the computer for years, you can replace an SSD, or even buy a new one. Hope for a best result.
