Hello,

I've been following along the SBSendEmail example from Apple.

https://developer.apple.com/library/content/samplecode/SBSendEmail/Introduction/Intro.html

The same should be able to be done via pyobjc as well. The alloc init cycle
of the outgoing message object yields me a Python future object. Example
code below:

from ScriptingBridge import SBApplication


apple_mail = SBApplication.applicationWithBundleIdentifier_(
    'com.apple.mail')

apple_mail_message_class = apple_mail.classForScriptingClass_(
    'outgoing message')

apple_mail_message = apple_mail_message_class.alloc().initWithProperties_({
    'subject': 'foo',
    'content': 'bar',
    })

Only alloc()ing the object yields an ephemeral pseudo-SB object as improper
SB use does.

>>> apple_mail_message = apple_mail_message_class.alloc()

>>> apple_mail_message
<MailOutgoingMessage objective-c instance 0x7fc0586d24c0>

>>> apple_mail_message.subject()

>>> apple_mail_message.subject()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: cannot access attribute 'subject' of NIL
'MailOutgoingMessage' object

>>> apple_mail_message
<MailOutgoingMessage objective-c instance 0x0>

My understanding of what is going here is that interacting with it once
makes it go away as its retain count is 0 in the Obj-C VM.

The future object contains its properties in its repr().

>>> apple_mail_message
<future MailOutgoingMessage with properties {
    content = bar;
    subject = foo;
}>

>>> type(apple_mail_message)
<objective-c class SBProxyByClass at 0x7fffa69f9fe0>

So, how to work with these future objects? Or am I doing something
fundamentally wrong in how I'm trying to chase the obj-c example?

To answer myself, one just has to find the correct kind of an NSArray-ish
with an .addObject_(foo) which will eat the proxied class instance in
question. Just as the docs say.

I?m new to Python. I seem to have three partially installed Pythons on my Mac Sierra.

One from Apple
One from Homebrew
And one from the Python Mac installer

In particular, for example, I have a python executable in /usr/bin:

$ which python
/usr/bin/python

This is an actual executable not a symkink. There are a whole bunch of python related files in that directory:

python           python-config    python2.6        python2.6-config python2.7        python2.7-config pythonw          pythonw2.6       pythonw2.7


I think they all came from the python.org python installer.

I would like to fully uninstall the Python (and related files) that I got from the Mac Python Installer from the python web site. I can?t find up to date instructions. 

Does anyone know how to do this? Thanks!

Pito Salas

I think the /usr/bin/python executable you?re seeing is the Apple-supplied one.

Here?s what I have in /usr/bin, which is all from Apple:

$ ls -l /usr/bin/pyth*
-rwxr-xr-x  1 root  wheel  66576 Apr 29 02:29 /usr/bin/python
-rwxr-xr-x  5 root  wheel    925 Jul 31  2016 /usr/bin/python-config
lrwxr-xr-x  1 root  wheel     75 Jun 22 13:26 /usr/bin/python2.6 -> ../../System/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6
lrwxr-xr-x  1 root  wheel     82 Jun 22 13:26 /usr/bin/python2.6-config -> ../../System/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6-config
lrwxr-xr-x  1 root  wheel     75 Jun 22 13:26 /usr/bin/python2.7 -> ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
lrwxr-xr-x  1 root  wheel     82 Jun 22 13:26 /usr/bin/python2.7-config -> ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-config
-rwxr-xr-x  1 root  wheel  66576 Apr 29 02:30 /usr/bin/pythonw
lrwxr-xr-x  1 root  wheel     76 Jun 22 13:26 /usr/bin/pythonw2.6 -> ../../System/Library/Frameworks/Python.framework/Versions/2.6/bin/pythonw2.6
lrwxr-xr-x  1 root  wheel     76 Jun 22 13:26 /usr/bin/pythonw2.7 -> ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/pythonw2.7
$

Homebrew puts everything in /usr/local/bin, and I think so does the official Python Mac installer (it did when I was still responsible for it:-).

Normally you should never touch anything in /usr/bin or /usr/lib. That is Apple territory.

If it is in /usr/bin, it shouldn't.

Delete /Library/Frameworks/Python.framework/ and all links in /usr/local/bin and /usr/local/lib that point towards something inside that directory.

On the other hand, I find it very useful to have a Python from python.org installed as they are usually more up to date than the Apple supplied one. If you tell the installer to install the links in /usr/local, and put /usr/local/bin in your PATH before /usr/bin, you will use these, and Apple will still use their own version.

You can't any more.

$ touch /usr/bin/just-testing
touch: /usr/bin/just-testing: Operation not permitted
$ sudo touch /usr/bin/just-testing
Password:
touch: /usr/bin/just-testing: Operation not permitted

Since System Integrity Protection came out with El Capitan, unless you reboot into recovery mode and type some "void your warranty" commands into the terminal app on the recovery partition, it's simply no longer possible for 3rd-party applications and installers to write files into /usr/bin.  Attempting to install over /usr/bin/python on any macOS released in the last 2 years will just fail.
