Download Binaries for Apple Mac OSX

These binaries are for OS X. They are only for OS X 10.4 - 10.10. Usually the binary for a version or two before yours should work, e.g. 10.7 should work on 10.8. For more information read the installation instructions.
Currently, SageMath does not work on the new OS X 10.11!
For more information: Ticket #19370.
To get the binary running, you can (temporarily) disable SIP:
  1. Restart your Mac.
  2. Before OS X starts up, hold down Command-R and keep it held down until you see an Apple icon and a progress bar. Release. This boots you into Recovery.
  3. From the Utilities menu, select Terminal.
  4. At the prompt type exactly the following and then press Return: csrutil disable
  5. Terminal should display a message that SIP was disabled.
  6. From the menu, select Restart.
You can re-enable SIP by following the above steps, but using csrutil enable instead.

Consider downloading via BitTorrent web-seed files! Then your download is balanced across all servers, resumeable, and the checksum of the data is automatically verified. This gives you optimal speed and protection against corrupt/malicious data. Either install a libitorrent based client like Deluge or Aria2 for the command-line (e.g. sudo apt-get install aria2 and then $ aria2c http://...*.torrent). Download here.
