How do I properly dispose of an old CPU? It has no useful info on it. I just don’t want to throw it in the trash.
You can get rid of that machine a number of ways, including:
- Best Buy will take recyclable technology, requiring neither a fee nor an appointment.
- You can give stuff away at craigslist or Freecycle.
- You can take any non-trashable material or items — from batteries to paint to televisions — to the hazardous materials disposal depot over at Culebra and 410 (dial 311 in San Antonio for details).

Goodwill takes computers working or not and they have lots of donation locations around the city.
Too right — Thanks!
I think removing the hard drive before giving away the computer would be important.
On a tower computer, definitely, but on most Macs that’s a difficult if not impossible task. (We won’t do it.) But you make a salient point: A proper “secure erase” in Disk Utility is crucial.
