If your Mac is under 5 years old, you’re golden. Keep the OS updated, run occasional disk cleanup, and consider a cloud backup. It will likely serve you well for another two to three years.
If your Mac is 5 to 8 years old, think about an SSD upgrade if it doesn’t have one. This single change makes an old Mac feel reborn. Also, check the battery health in System Settings. A worn battery is a sad battery.
