Tails should work on any reasonably recent computer, say manufactured after 2005. Here is a detailed list of requirements:

  • Either an internal or external DVD reader or the possibility to boot from a USB stick or SD card.
  • Tails requires an x86 compatible processor: IBM PC compatible and others but not PowerPC nor ARM. Mac computers are IBM PC compatible since 2006.
  • 2 GB of RAM to work smoothly. Tails is known to work with less memory but you might experience strange behaviours or crashes.
