Hi Adobe Support staff,
I keep getting update notices for Flash Player.
However, I have an old Mac Pro and cannot update yet
with my present operating system.
Could you please stop sending me these notices?
Uhh... that's terrible advice. I mean, it works, but if you're doing anything remotely sensitive, like banking, healthcare, checking your email that resets credentials for those kinds of accounts... you really want to be browsing the web on a current OS with a current browser and Flash Player installed.
If you're cost sensitive and/or cannot afford to upgrade to a modern operating system, modern Linux distributions like Mint Linux offer a free solution that includes modern operating system level security mitigations and cryptography support. If you prefer Windows or Macintosh, a decent entry-level Win10 laptop can be had in the $400 range, a decent entry-level Chromebook will run you about $250, and Walmart and Amazon both sell refurbished Apple products through their websites, if you'd prefer an inexpensive alternative to retail Apple prices.
Identity theft is expensive and painful to recover from. Please stay safe out there. 🙂
