• Mac Os Versions

Is your Mac up to date with the latest version of the Mac operating system? Is it using the version required by a product you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.

If your macOS isn't up to date, you may be able to update to a later version.

Downloaded the iso image and proceeded to make a Mac OS X bootable USB on windows. To create a bootable media to install Mac OS X leopard on my old macbook A1181. I used imageusb and installed. I was very happy to find this 10.5.4 version which worked perfectly. Many thanks to all.

Which macOS version is installed?

• The first release of the new OS — Mac OS X Server 1.0 — used a modified version of the Mac OS GUI, but all client versions starting with Mac OS X Developer Preview 3 used a new theme known as Aqua. Aqua was a substantial departure from the Mac OS 9 interface, which had evolved with little change from that of the original Macintosh operating.
• The above applies to the official Python distribution, which is 32-bit only for 2.6 while 32/64-bit bundles are available for 2.7 and 3.x.For alternative 64-bit Pythons (either from Apple or home-built) on Snow Leopard, you may need to extend your build flags to specify the architecture by setting LDFLAGS and FFLAGS.

From the Apple menu  in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Big Sur, followed by its version number. If you need to know the build number as well, click the version number to see it.

What is the latest macOS version?

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Big Sur. As updates that change the macOS version number become available, this article will be updated to show the latest version of that macOS.

If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar and Photos.

These instructions describe how to build NumPy and SciPy libraries fromsource.

If you just want to use NumPy or SciPy, install pre-built binaries as describedin /install.

Python¶

Apple ships its own version of Python with OS X. However, westrongly recommend installing the official Python distribution.

Alternatively, use Python from one of the OS X package managers(Homebrew, MacPorts, Fink).

Compilers (C/C++/FORTRAN/Cython)¶

Though virtually any commercial C/C++ compiler may be used with SciPy, OS Xcomes with GNU C compilers pre-installed. The only thing missing is the GNUFORTRAN compiler.

We recommend gfortran; this is a free, open source, F95 compiler. We suggest youuse the following binaries:

• gfortran installed via Homebrew, or,
• http://r.research.att.com/tools/gcc-42-5666.3-darwin11.pkg (for Xcode4.2 or higher)

See this site for the most recent links.

Unless you are building from released source packages, the Cython compiler is also needed.

BLAS/LAPACK Installation¶

You will also need to install a library providing the BLAS and LAPACKinterfaces. ATLAS, OpenBLAS, and MKL all work. OpenBLAS can be installedvia Homebrew.

As of Scipy version 1.2.0, we do not support compiling against the systemAccelerate library for BLAS and LAPACK. It does not support a sufficientlyrecent LAPACK interface.

Version-specific notes¶

This section notes only things specific to one version of OS X or Python.The build instructions in Obtaining and Building NumPy and SciPy apply to all versions.

Obtaining and Building NumPy and SciPy¶

You may install NumPy and SciPy either by checking out the sourcefiles from the Git repositories, or unpacking them from a sourcearchive file from /scipylib/download. If you choose the latter,simply expand the archive (generally a gzipped tar file), otherwisecheck out the following branches from the repository:

Both NumPy and SciPy are built as follows:

The above applies to the official Python distribution, which is 32-bitonly for 2.6 while 32/64-bit bundles are available for 2.7 and3.x. For alternative 64-bit Pythons (either from Apple or home-built)on Snow Leopard, you may need to extend your build flags to specifythe architecture by setting LDFLAGS and FFLAGS.

Note that with distutils (setup.py) given build flags like LDFLAGSdo not extend but override the defaults, so you have to specifyall necessary flags. Only try this if you know what you’re doing!

Building Relationships Mac Os 11

After a successful build, you may try running the built-in unit testsfor SciPy:

Be sure not to import numpy or scipy while you’re in the numpy/scipysource tree. Change directory first.

Mac Os Versions

If you have any problems installing SciPy on your Macbased on these instructions, please check the scipy-users andscipy-dev mailing list archives for possible solutions. If youare still stuck, feel free to join scipy-users for furtherassistance. Please have the following information ready:

• Your OS version
• The versions of gcc and gfortran and where you obtained gfortran
  • $gcc--version
  • $gfortran--version
• The versions of numpy and scipy that you are trying to install
• The full output of $pythonsetup.pybuild
