Building a PyQt5/PySide2 macOS Application

Preface

As part of my professional duties, I have been tasked with developing a desktop application to analyze audio files. This desktop application would need to be work across platforms (Windows, macOS and Ubuntu), and I cannot rely on dependencies having already been installed (such as Python itself). Naturally I turned to Qt (and more specifically, Qt for Python) due to its capabilities for creating GUI applications that work across OSs. As I could not be dependent on the end user having Python installed (so no deploying a wheel and calling it good), I decided it may be worth trying to make native installers (deb packages for linux, .app bundles and .dmg files for macOS, and setup.exe files for Windows).

In short, here were the objectives I aimed to have

Cross-Platform compatible GUI application
Deployment to users via native installers (no assumption of python being on the target machine)

This may work with other Macbook Pro models that have an Intel GPU and a NVidia one, but I only have proof that this works on a MacBook Pro Mid 2014 (MacBookPro11,3) with Ubuntu 18.04. If you want to be sure about which model you have, run sudo dmidecode -t system in the Terminal and you will see the information about the system including the serial number and product name (MacBookPro11,3 in my case). I'm assuming you have installed the NVidia propietary drivers, which can be installed from the application "Software & Updates" in the tab "Additional Drivers".

Steps to use the Intel GPU:

Run lspci |grep VGA and check that only one line mentioning "NVIDIA" is printed. This is to be sure that you are required to do the following steps. If two lines appear, and one of those mentions "Intel", then you probably do not need to activate the GPU but only select it as the main GPU (jump to the step where you have to "Open nvidia-settings").

How to automate the build of bottles on your Homebrew tap

This tutorial is a follow-up to the discussion we had on davidchall/homebrew-hep#114. It relies on a fork of the test-bot provided by davidchall; you can get it with brew tap maelvalais/test-bot. First:

the Github project must be of the form https://github.com/<user>/homebrew-<tap> with the following tree (I give the example of one of my formulas, touist):

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Works for macOS Sierra and High Sierra

Taken from 2011 Macbook Pro Graphics Card FIX 100% WORKING!!!

EDIT This method works! But there is an improved version for better thermal management and brightness keys functionality. See improved version -> https://gist.github.com/cdleon/d1eff7246a25193304284ecec40445b0

Enter Recovery Mode (text mode)

if you are on high sierra 10.13.6+ you might need to use Command + r instead

Boot up holding down Command + r + s

	# Summary
	A few notes I took to see if I could use MacOS as Hypevirsor in a similar fashion to Linux
	I wanted to see how few addons were needed instead of using Parallels, Virtual Box, VM Fsion etc.
	The idea is to use QEMU, Hypervisor Framework (https://developer.apple.com/documentation/hypervisor) and some custom host networking.

	# Installations
	brew install qemu (For controlling Hypervisor Framework)
	brew install cdrtools (For making cloud init iso's)
	http://tuntaposx.sourceforge.net/download.xhtml (For customer tap based networking)
