1 How to install Python 1.5.2b1 on your Macintosh
2 -----------------------------------------------
4 If this is your first encounter with Python: you definitely need the
5 common user documentation (common to all platforms). You can find this
6 (in various forms) on www.python.org and ftp.python.org. Through
7 there, or via http://www.cwi.nl/~jack/macpython.html you can also find
8 the most recent MacPython distribution.
10 Mac-specific documentation is included in this distribution in folder
11 Mac:Demo. The documentation is sparse, but it will have to serve for
12 now. The documentation is in HTML format, start with index.html.
16 There are still problems with cfm68k Python. 68K Mac users should
17 probably try to use the cfm68k distribution first, and revert to the
18 classic 68k distribution in case the bugs make their Python
19 unworkable. The main problem is that packages ("dotted import") and
20 NumPy printing don't work.
25 There are three flavors of Python: PowerPC, cfm68k and Classic 68k
26 (the FAT flavor is just a combination of the first two, which is handy
27 if you want to install Python on a fileserver or so). 68K-mac owners
28 should definitely use the cfm68k version if possible, since it enables
29 the use of applets and dynamically loaded modules and usually has a
30 smaller memory footprint. If you have an older system than MacOS 8 it
31 does however need the CFM68K Runtime Enabler which is available from
32 Apple (available for free from
33 <http://support.info.apple.com/ftp/swhome.html>, included since MacOS
34 7.6.1 and builtin to the system since MacOS 8). If your machine is
35 pre-68020 you cannot use cfm68k and you can install the classic 68k
38 After the installer finishes it automatically launches the
39 ConfigurePython applet, to finish configuration of your Python
40 installation (except for classic 68K installations, where no extra
41 configuration is needed).
43 If you have a pre-system 7 macintosh: sorry, this release will not work
44 on your system. Too many sys7 features are used to make a sys6 python
47 If you don't have enough memory: the sizes choosen are somewhat
48 arbitrary. Try lowering the application sizes in the finder "get info"
49 window, and seeing whether the resulting python is still usable. Some
50 modules (Tkinter comes to mind) need a lot of memory, so it may also be
51 necessary to increase the application size.
53 A final note to CFM68K (and possibly PPC) users: the Code Fragment
54 Manager can (incorrectly) produce "library not found" and other strange
55 error messages when it really means that there is not enough room in the
56 system heap. Decreasing (yes, *de*creasing) the size of the interpreter
57 and/or enabling virtual memory may solve these problems.
62 The first step thing you could try is to run "compileall.py" to create
63 all .pyc files, but this isn't very important, as pyc files are
64 created on-the-fly as well. You may also want to skip this step if you
67 Next, it is probably a good idea to run the automatic tests. Start
68 Python and "import test.autotest". This should not print any
69 errors. It will, however, print some messages about optional features
70 not supported. Also, if you didn't run compileall before autotesting
71 you may run out of memory the first time you run the
72 tests. test_socket may also fail if you have no internet
73 connection. Please also read the Relnotes file for other minor
74 problems with this distribution.
76 PPC and CFM68K users have a couple of applets in the main folder they
77 may want to try, (68K users can use the corresponding scripts from the
80 - EditPythonPrefs allows you to edit the preferences file, to change the
81 python home folder or modify the initial sys.path setting. The default
82 settings are somewhat arbitrary, you can remove tkinter if you don't use
83 it and possibly add Extensions:img:Lib. - mkapplet creates a python
84 applet, a tiny application written in python. Drop a python source on it
85 and out comes the application. More information can be found in the
88 If you have a slow machine you may want to disable automatic site.py import
89 since site.py does not do too much on the mac (unless you make it do
90 something), and it can take a few seconds.
92 PPC and CFM68K users will see one more file in the python folder:
93 PythonApplet. This is the template for building applets, leave it alone.
94 The applet is "fat", containing both PPC and CFM68K code. Hence, applets
95 built with it can be transported to machines with the other
101 Two items are installed in the system folder: the interpreter shared
102 library "PythonCore 1.5.2b1" lives in the Extensions folder and the
103 "Python 1.5.2b1 Preferences" file in the Preferences folder. All the rest
104 of Python lives in the folder you installed in.
109 There are some readme files in the "Read me files" folder that may
110 contain useful information. There is also a first stab at documentation
111 (plus examples) in the Mac:Demo folder. The toplevel Demo folder has
112 machine-independent demos. See the file Readme-mac for mac-specific
113 notes. The Mac:Lib:test folder also has some programs that show simple
114 capabilities of various modules.
116 The "scripts" folder has some sample scripts. Some are useful, some are
117 just interesting to look at to see how various things work. The MkDistr,
118 mkapplet and fullbuild scripts (plus the ones mentioned above) may help
119 you to understand how to use AppleEvents and various other toolboxes
122 The 'img' group of modules, which handles I/O of many different image
123 formats is included, but without documentation. You can find docs at
124 ftp://ftp.cwi.nl/pub/jack/python/img (or somewhere around there).
126 Finally there is a Mac:Contrib folder which contains some contributed
127 software, including a Real Programming Environment and some AppleScript
130 Upgrading from older Python releases
131 ------------------------------------
133 Since release 1.4 Python releases are independent of each other, with
134 separate Preferences files, shared library names, etc. The good news is
135 that this means you can keep your older version around if you are unsure
136 whether to upgrade. The bad news is that your old preference settings
137 are lost and you have to set them again.
139 After you are satisfied that 1.5.2b1 works as expected you can trash
140 anything in the system folder that has "python" in the name and not
