Service Imac

Yes, as of June 2019. However, if there is a nearby Best Buy, then there probably is a local Apple Store, and I would trust the Apple Store with an iMac long before I would the Geek Squad. Make an appointment with the Apple Store and take the iMac in to them. Perform a Time Machine backup before you let anyone touch the iMac.

How did you customized the bestbuy link?

In a separate browser tab, get the full URL link to the content you want to link too. Copy to the clipboard. Back in this editor, select the text that you want to apply that URL link too, then click the link icon in the bottom toolbar. It will open a panel where you can then paste in the full URL, and then press return. That will apply the link to the selected text.
