A 2019 Retina iMac was primarily used by two employees, who had their own password-protected user accounts. The computer was connected to a cheap wireless router that was estimated to be 10 to 13 years old, which compromised its security level. The adjacent computer, a Windows PC that belonged to the owner, malfunctioned and prompted the user to call for support, a decision made without thorough knowledge of the potential risks involved. One of the employees reported the situation, indicating that their coworker was using the iMac at the time the problems arose. Due to the age and model of the two computers, the risk of an infection spreading from the Windows PC to the iMac was a pressing concern, especially given the lack of experience from the PC user. No backup or recovery disks were available, and the employee expressed uncertainty regarding the Mac's security status after the incident. Furthermore, it was noted that the Mac was not connected to the owner’s Apple ID, as they planned to avoid linking it moving forward. Concerns lingered about whether the malware could have affected the iMac, considering the insecure network conditions that were present. Without recovery disks, the user wondered if they could still perform an OS reinstall by connecting the iMac to their home network. They had heard that the device might support Internet Recovery, which could allow for a smooth reinstallation of macOS. To facilitate this, a key combination would be necessary to ensure they could initiate this recovery process from the Internet, provided the conditions were suitable at that time.
