Aug 28, 2017 Hello, I use CXFreeze in windows and now in Mac OS. I'm in environment python3 and i have an issues without any solution. When i build.exe in my mac it. Jan 09, 2012 If you've developed a USB device-access application to run in a PowerPC-based Macintosh, you probably perform some byte swapping on data you read from the USB bus because the PowerPC processor uses the big-endian format. For example, the USB configuration descriptor structure contains a two-byte field that holds the descriptor length.Latest version

About original libusb:
Borrowed from the original website:
libusb - A cross-platform user library to access USB devices
libusb is a C library that provides generic access to USB devices.It is intended to be used by developers to facilitate the production ofapplications that communicate with USB hardware.
It is portable: Using a single cross-platform API, it provides accessto USB devices on Linux, OS X, Windows, Android, OpenBSD, etc.
It is user-mode: No special privilege or elevation is required for theapplication to communicate with a device.
It is version-agnostic: All versions of the USB protocol, from 1.0 to 3.1(latest), are supported.
What platforms are supported?
Linux, OS X, Windows, Windows CE, Android, OpenBSD/NetBSD, Haiku.
For additional information, please consult theFAQor theWiki.

Python on a Macintosh running Mac OS X is in principle very similar to Python onany other Unix platform, but there are a number of additional features such asthe IDE and the Package Manager that are worth pointing out.
4.1. Getting and Installing MacPython¶
Mac OS X 10.8 comes with Python 2.7 pre-installed by Apple. If you wish, youare invited to install the most recent version of Python 3 from the Pythonwebsite (https://www.python.org). A current “universal binary” build of Python,which runs natively on the Mac’s new Intel and legacy PPC CPU’s, is availablethere.
What you get after installing is a number of things:
Python3.8folder in your
Applicationsfolder. In hereyou find IDLE, the development environment that is a standard part of officialPython distributions; PythonLauncher, which handles double-clicking Pythonscripts from the Finder; and the “Build Applet” tool, which allows you topackage Python scripts as standalone applications on your system.
/Library/Frameworks/Python.framework, which includes thePython executable and libraries. The installer adds this location to your shellpath. To uninstall MacPython, you can simply remove these three things. Asymlink to the Python executable is placed in /usr/local/bin/.
The Apple-provided build of Python is installed in
/usr/bin/python,respectively. You should never modify or delete these, as they areApple-controlled and are used by Apple- or third-party software. Remember thatif you choose to install a newer Python version from python.org, you will havetwo different but functional Python installations on your computer, so it willbe important that your paths and usages are consistent with what you want to do.
IDLE includes a help menu that allows you to access Python documentation. If youare completely new to Python you should start reading the tutorial introductionin that document.
If you are familiar with Python on other Unix platforms you should read thesection on running Python scripts from the Unix shell.
4.1.1. How to run a Python script¶
Your best way to get started with Python on Mac OS X is through the IDLEintegrated development environment, see section The IDE and use the Help menuwhen the IDE is running.
If you want to run Python scripts from the Terminal window command line or fromthe Finder you first need an editor to create your script. Mac OS X comes with anumber of standard Unix command line editors, vim andemacs among them. If you want a more Mac-like editor,BBEdit or TextWrangler from Bare Bones Software (seehttp://www.barebones.com/products/bbedit/index.html) are good choices, as isTextMate (see https://macromates.com/). Other editors includeGvim (http://macvim-dev.github.io/macvim/) and Aquamacs(http://aquamacs.org/).
To run your script from the Terminal window you must make sure that
/usr/local/bin is in your shell search path.
To run your script from the Finder you have two options:
Drag it to PythonLauncher
Select PythonLauncher as the default application to open yourscript (or any .py script) through the finder Info window and double-click it.PythonLauncher has various preferences to control how your script islaunched. Option-dragging allows you to change these for one invocation, or useits Preferences menu to change things globally.
4.1.2. Running scripts with a GUI¶
With older versions of Python, there is one Mac OS X quirk that you need to beaware of: programs that talk to the Aqua window manager (in other words,anything that has a GUI) need to be run in a special way. Use pythonwinstead of python to start such scripts.
Python Usb Library Mac Os
With Python 3.8, you can use either python or pythonw.
Python on OS X honors all standard Unix environment variables such as
PYTHONPATH, but setting these variables for programs started from theFinder is non-standard as the Finder does not read your
.cshrc at startup. You need to create a file
~/.MacOSX/environment.plist. See Apple’s Technical Document QA1067 fordetails.
For more information on installation Python packages in MacPython, see sectionInstalling Additional Python Packages.
4.2. The IDE¶
MacPython ships with the standard IDLE development environment. A goodintroduction to using IDLE can be found athttp://www.hashcollision.org/hkn/python/idle_intro/index.html.
4.3. Installing Additional Python Packages¶
There are several methods to install additional Python packages:
Packages can be installed via the standard Python distutils mode (
Mac sierra won't open picture library from file transfer. Jul 12, 2017 Maybe it’s become corrupted and Photos won’t open, or maybe you just want to start fresh and archive your old one. Regardless, to create a new System Photo Library, first open the location where your current system library is and drag it to a backup spot if you want to keep it (recommended). Mar 18, 2020 If your Photos library won't open, or if Photos behaves unexpectedly, the Photos library repair tool might resolve the issues. Follow these steps to use the Photos library repair tool: Hold down the Option and Command keys while you open Photos on your Mac. In the dialog that appears, click Repair to start the repair process. Jan 08, 2018 Should not be an issue because the format of the drive does not effect the type of file (in this case probably JPEGs), so if El Capitan was able to read the drive and copy the photos to the Mac's internal drive, that should not effect Sierra's ability to see and read them. Mar 18, 2020 When the process is complete, Photos opens your library. Follow these steps to use the Photos repair tool: Make sure that you backed up your main Photos library. Quit Photos if it's open. Press and hold the Option and Command keys as you open Photos again. The Repair Library dialog appears.
Many packages can also be installed via the setuptools extensionor pip wrapper, see https://pip.pypa.io/.
4.4. GUI Programming on the Mac¶
There are several options for building GUI applications on the Mac with Python.
PyObjC is a Python binding to Apple’s Objective-C/Cocoa framework, which isthe foundation of most modern Mac development. Information on PyObjC isavailable from https://pypi.org/project/pyobjc/.
The standard Python GUI toolkit is
tkinter, based on the cross-platformTk toolkit (https://www.tcl.tk). An Aqua-native version of Tk is bundled with OSX by Apple, and the latest version can be downloaded and installed fromhttps://www.activestate.com; it can also be built from source.
wxPython is another popular cross-platform GUI toolkit that runs natively onMac OS X. Packages and documentation are available from https://www.wxpython.org.
PyQt is another popular cross-platform GUI toolkit that runs natively on MacOS X. More information can be found athttps://riverbankcomputing.com/software/pyqt/intro.
4.5. Distributing Python Applications on the Mac¶
The “Build Applet” tool that is placed in the MacPython 3.6 folder is fine forpackaging small Python scripts on your own machine to run as a standard Macapplication. This tool, however, is not robust enough to distribute Pythonapplications to other users.
The standard tool for deploying standalone Python applications on the Mac ispy2app. More information on installing and using py2app can be foundat http://undefined.org/python/#py2app.
4.6. Other Resources¶
The MacPython mailing list is an excellent support resource for Python users anddevelopers on the Mac:
