Update install from source for macOS

[gernophil]

Hey,
I just tried your manual to install QC from source for macOS. Maybe this manual requires some updates? Happy to provide a PR, but I first wanted to ask some questions/comments.

• Do you really need the Xcode CLI tools, since you are linking python.org. IIRC, this should run without the Xcode CLI tools.
• Why do you need the get-pip.py? pip(and its aliases pip3 and python -m pip) is included in every python install from python.org.
• The path python3 /applications/QualCoder-master/qualcoder/__main__.py does not exist after the first install method (python3 -m pip install .). macOS can be case-sensitive so it should better be /Applications and the folder QualCoder-master/qualcoder does not exist even after running python3 -m pip install ., but I was able to run QualCoder-master/src/qualcoder after successful installation. Is that the correct way to run it?
• The second method (python3 setup.py py2app) fails with RecursionError: maximum recursion depth exceeded.

Hi @gernophil

Since we have compiled versions for macOS now, the instructions for the installation from source have been a bit neglected, yes. It would be great if you could suggest an update.
I cannot answer all your questions, but give some hints:

• "Do you really need the Xcode CLI tools..." => I'm not sure. It might be needed to compile C/C++ extensions during the installation of some python packages.
• "Why do you need the get-pip.py?..." => probably unnecessary
• "The path python3 /applications/QualCoder-master/qualcoder/main.py does not exist..." => yes, you are right. The code has recently been moved to the src subfolder. python3 /Applications/QualCoder-master/src/qualcoder/__main__.py should work, I guess.
• "The second method (python3 setup.py py2app) fails with RecursionError..." => I think you can remove that option. Compiling QualCoder needs extra options set in the spec file for pyinstaller. Py2app seems to be a simplified version of pyinstaller which does not support spec files. IMHO, we don't need instructions for compiling at all, since we now provide compiled versions ourselves.

Yes, I would be happy for you to go ahead and update the manual install instructions. Without a macOS up to now we have relied on the advice of others to present the install instructions.

Seems like installation from source works exactly like with the instructions given for windows. I'll try to make a PR later. I've seen you are using pyinstaller<=6.4.0. I am aware of the issues with higher version for windows, but that's not an issue for Mac or Linux. And higher PyInstaller version often simplify die bundling a lot, e.g. by using newer hooks. So, if this is not totally necessary, I would recommend using newer versions for macOS and Linux. Maybe I can also give this a shot later.
