'hpRaster.bundle Will Damage Your Computer' Error

Mac users with certain HP printer models might be surprised unpleasantly by a macOS warning prompt displaying the following message - 'hpRaster.bundle Will Damage Your Computer.' These alert prompts are part of the automated security measures that Apple introduced to stem the distribution of PUPs (Potentially Unwanted Programs) within their ecosystem. Their goal is to detect and bring to light various adware, browser hijackers, rogue applications, etc. that have managed to sneak onto the user's Mac system. However, the system also has begun to flag certain outdated printer drivers. 

The explanation given to users is that the credentials associated with several older versions of Mac drivers were revoked unintentionally. Users with the affected printer models will then be likely to encounter the macOS warning prompt. One of the HP models that have been observed to cause the 'hpRaster.bundle Will Damage Your Computer' error is the HP LaserJet P1102w. Keep in mind that the affected printers might not be able to operate normally until the problem is fixed.
