Basic Mac Troubleshooting Steps
A number of issues you may be experiencing with your Mac can be resolved by performing an SMC and PRAM reset. These two resets will not erase any of your data - they simply reset how the components in your computer talk to each other.
Performing an SMC or PRAM reset can resolve these issues:
- Computer won't charge
- Computer won't turn on
- Display not turning on
- Computer running slow
- Fan running abnormally
- Grey screen on startup
- Question mark on startup
- Wi-Fi/Bluetooth slow or not working
- Ports not working (e.g. USB)
- and many more things... It's always a good first troubleshooting step.
Another good troubleshooting step is to run the First Aid function in Disk Utility.
- Checks your hard drive's health
- Repairs any file system errors
- Can speed up your machine
If you think you may have Malware or a Virus, we recommend the free version of Malwarebytes for Mac.
- The free version detects and removes Malware for free, and does not expire. You have to manually start a scan.
- The difference between the Free and Premium version is that the Premium version automatically runs scans for you periodically and acts as a proactive Anti-Virus.
As a last resort effort before looking into hardware repair options, your best bet is to Backup your Mac (if possible) and Reinstall MacOS.
