Factory reset for iMac 2013

Hi

Can some-one advise please on the best way to do a factory reset on a 2013 21.5 inch iMac running very slowly on MacOS Catalina?

Thanks

Hi there!


Erasing your Mac may not fix the poor performance.


If you’d like, in order to start diagnosing your Mac to figure out why it is slow, we first need to know some information about it. 


Please upload a screenshot of your Mac’s storage information. In the Finder, choose Go > Utilities, then double-click the Disk Utility icon. (Disk Utility is located in the /Applications/Utilities folder.) Alternatively, click Launchpad in the Dock, type Disk Utility in the search field, then click the Disk Utility icon. Once Disk Utility is open, take a screenshot of the information it automatically opens to, which will be your startup disk. Next, select View Show All Devices in Disk Utility and select the top-level, non-indented, disk entry. In most cases, this name will be one of the following:


  • APPLE HDD…
  • APPLE SSD…
  • Fusion Drive


Then, take a screenshot of the newly selected entry. Upload all screenshots here. 


Next, it is recommended you Use Apple Diagnostics to test your Mac in order to identify any potential issues. Let us know the results of this test. 


Finally, list any anti-virus, anti-malware, cleaning, or VPN software you have installed.
