Whenever Apple comes out with a major new release of its OS, some Macintosh hardware gets left behind. While Leopard includes support for PowerPC Macs, itis worth looking at Appleis history to see if, according to Daniel Dilger at Roughly Drafted. 'Previous versions of Apple?s OS have drawn the line for officially supported Macs based on practical considerations, rather than just being arbitrary or artificial. Hereis what the past suggests for Mac OS X Leopard and the version that comes after it,' Mr.

Dilger wrote. It turns out that there are some fairly frequently used metrics for deciding whether a new OS version needs to leave a line of hardware behind. By looking at how Apple has done this going all the way back to System 7 in 1996, itis possible to make a good prediction about what Mac OS X 10.6 will support. While Apple has a tendency to make radical changes in hardware, such as the Motorola 680x0 transition to PowerPC, then PowerPC to Intel, the pace of change has still afforded a rather generous position by Apple in how far back they go.

For example, 'The release of Mac OS X Panther 10.3 in 2003 extended support back to Macs with G3 processors and built-in support for USB. This wasnit due to an actual requirement for USB, but rather a shorthand way to describe a cutoff for the support of the significantly different architecture of 'Old World' Macs designed prior to the iMac, as all New World Macs also provided support for USB. Panther retained a roughly five year support window for existing Mac models,' Mr.

Dilger noted. Another major factor to consider is the aggregate of how many Macs lie within, say, a five year window in the past. For example, the majority of the installed base of Macs today, about 22 million, is still PowerPC. These customers will be buying software well into 2010.

In addition, the architecture of recent Macs, even through the PPC to Intel transition, hasnit changed that much since 2003. There are additional technical considerations, thanks to the way Apple has set up its 32- and 64-bit architectures, something Microsoft has had trouble with.

The bottom line was easy to arrive at. 'Worrying about 10.6 or even 10.7 being Intel-only shouldnit be among anyoneis greatest concerns,' Mr. Dilger concluded.

This is NOT THE OFFICIAL SITE FOR Scisoft OSX. This is an mirror download site in case the official one goes offline. You probably want to check the first before using these links. I have not gotten permission to place this archive online but I am doing so because some people are having problems accessing the Scisoft OSX download pages.I’m providing some instructions here, but they are copied from the page. I strongly recommend you go there for any updated information.

It will only run on 64bit processors under Snow Leopard.:  This is a 615 Megabyte gzipped tarball file. It is smaller than the PPC version in part because of the lack of manpages for the various packages. The previous versions of SciSoft OSX I have left online include:.

You will be asked for your account password to allow ‘sudo’ to run the tar command as root. If Safari un-gzipped the file, you might to instead use the command: sudo tar -C / -xvf ScisoftOSXmacintel2009.10.1.tar. For versions previous to Scisoft OSX 2009.10.1 Intel.

Unzip the package file. Double click the package, this will launch Apple’s Installer application, just accept the defaults and install the software. All the software will end up in the /scisoft directory, so there is little chance of mucking up your computer using this installer. Once the installer has finished you must set up your command line environment. In order to be able to run ANY of the Scisoft software, a Setup file needs to be sourced. Depending on whether your are a Bash or Tcsh user you need to modify your shell startup file as follow:. If you are using tcsh (preferred shell for Scisoft and IRAF) edit /.tcshrcand add the line source /scisoft/bin/Setup.csh (on PPC Installations) source /Applications/scisoft/all/bin/Setup.csh (on Intel Installations) source /usr/local/scisoft/bin/Setup.csh (on 64-bit Intel beta Installations) near the end of that file ( WARNING: versions before 2008.8.1 are not in /Applications/scisoft but rather just /scisoft).

Do not forget to add an empty line following this if this is the last entry in your startup file or this command will not be executed when you log on. If you are using bash (in which case, good luck) edit /.bashrcand add the line. /scisoft/bin/Setup.bash (on PPC Installations). /Applications/scisoft/all/bin/Setup.bash (on Intel Installations). /usr/local/scisoft/bin/Setup.bash (on 64-bit Intel beta Installations) near the end of that file (note there is a space between the initial period and the rest of that line). Do not forget to add an empty line following this if this is the last entry in your startup file or this command will not be executed when you log on.
