The MacTeX Working Group (MWG) proposes dropping support for macOS 10.5 (Leopard) and macOS 10.6 (Snow Leopard) in 2017. Thus that release would require a 64 bit Intel computer running macOS 10.7 (Lion) or higher. Note that with the upcoming Sierra release, we will still be supporting the last six versions of macOS.

We need to know how this change would effect the community at large. Therefore we ask for input from members of this list. If you object, it would be best to reply sooner rather than later.

If we take this step, a final version of MacTeX-2016 will be released in May, 2017, containing all updates before the server is shut down. All versions of MacTeX from past years are archived at the site below. Access this site as "Guest."


It is becoming more and more difficult to support Leopard and Snow Leopard as time goes on. The systems used to compile the PPC and 32bit binaries are getting rather old and can fail at any time. The new policy would only require one set of binaries, reducing Dick Koch's work load considerably. In addition there would no longer be the necessity of creating the PPC & 32bit versions of Ghostscript (that's four versions since each has a X11 and a no-X11 version).

As far as the MacTeX installer is concerned, besides the smaller set of binaries, it would no longer need to carry some old versions of GUI software specifically for 10.5 and 10.6 (e.g., TeXShop 2.47).

MacTeXtras now carries quite a few multiple versions of software which could also be paired down considerably (e.g., TeXmaker, BibDesk, Skim, Aquamacs).
Please reply to the list, or directly to me.

Good Luck,

Herb Schulz (for the MWG)
