FAQ

What does OC Snapshot do?

The OC Snapshot function will prompt you to select an OC folder, then walk the contents of the ACPI, Kexts, Tools, and Drivers directories within that folder - comparing all entries to the current document's ACPI -> Add, Kernel -> Add, Misc -> Tools, and UEFI -> Drivers respectively. It will add or remove entries as needed, and also ensures kext load order by comparing each kext's CFBundleIdentifier to all other kexts' OSBundleLibraries within their Info.plist - making sure that any kext that is relied on by others is loaded before them. It will also warn if it detects duplicate CFBundleIdentifiers (with support for MinKernel, MaxKernel, and MatchKernel overlap checks), and offer to disable all after the first found. It checks for disabled parent kexts with enabled child kexts as well. The schema used is (by default) determined by comparing the MD5 hash of the OpenCore.efi file to a known list of Acidanthera debug/release versions. If the MD5 hash does not match any known version, it will fall back to the newest schema in the script's snapshot.plist. This behavior can be customized in the Settings per the OC Snapshot Target Version menu.
What is the difference between OC Snapshot and OC Clean Snapshot?

Both snapshot variants accomplish the same tasks - they just leverage different starting points. An OC Clean Snapshot will first clear out ACPI -> Add, Kernel -> Add, Misc -> Tools, and UEFI -> Drivers, then add everything from within the respective ACPI, Kexts, Tools, and Drivers directory anew. A regular OC Snapshot starts with the information within the current document for those four locations, and only pulls changes - adding and removing entries as needed.
When should I use an OC Clean Snapshot vs an OC Snapshot?

Typically, an OC Clean Snapshot should only be used the first time you snapshot to ensure any sample entries in the config.plist are removed and added anew. Every subsequent snapshot should be a regular OC Snapshot to ensure any customizations you've made are preserved.
Can't click anything on Sonoma (14.x) and Newer

This appears to manifest when using python 3.11.x and older due to some isssue with tk and macOS. Updating to at least python 3.12.0 (found here) appears to fix it. If you are unable to update your python version, you can also move the window around before trying to click the elements in the treeview.
ProperTree opens a black window on macOS Monterey (12.x) and Newer

It appears the default tk implementation that ships with macOS Monterey (and the version installed with the Command Line Tools) doesn't display correctly. A workaround is to download and install the latest build of python from python.org (found here) which has a compatible tk bundled, then use the buildapp-select.command located in ProperTree's Scripts directory to build an application bundle targeting the installed python's path. You can then leverage the ProperTree.app bundle it creates.
ProperTree cannot open or save plist files on macOS Monterey (12.x)

This appears to be an issue with the built-in tk, and the earlier "universal" installers from python.org. With at least python 3.10.2, this issue has been resolved in the universal builds. You can get the latest python 3 installer here. After installing, use the buildapp-select.command located in ProperTree's Scripts directory to build an application bundle targeting the installed python's path. You can then leverage the ProperTree.app bundle it creates.
How can I have ProperTree open when I double-click a .plist file?

On macOS you can run buildapp-select.command located in ProperTree's Scripts directory to build an application bundle which can be associated with .plist files.

On Windows, you can run AssociatePlistFiles.bat located in ProperTree's Scripts directory to associate .plist files with ProperTree.bat, and also to add an Open with ProperTree option to the contextual menu when right-clicking .plist files. This approach is location-dependent, and moving your copy of ProperTree will require you re-run AssociatePlistFiles.bat.
When I try to run ProperTree, I get [ModuleNotFoundError: No module name 'tkinter']

That is because the graphical interface library that ProperTree depends on isn't present or cannot be detected, you need to install tkinter from your package manager.

To install it on Ubuntu (and Ubuntu-based distros), you can run sudo apt-get install python3-tk -y
ProperTree doesn't run because it doesn't have permissions, what gives?

This shouldn't happen and it is recommended that you download only from the official ProperTree repository, but if you are confident about your source, then running chmod +x ProperTree.command should sort it out
I use an international keyboard layout on macOS and some keys crash ProperTree with NSRangeException', reason: '-[__NSCFConstantString characterAtIndex:]: Range or index out of bounds

This is a bug in the Cocoa implementation of Tcl/Tk on macOS (discussed here). The latest python 2 installer from python.org ships with, and uses Tcl/Tk 8.6.8 which has this issue fixed. Given that the shebang in ProperTree.command leverages #!/usr/bin/env python - the first python 2 binary found should be used. buildapp-select.command from ProperTree's Scripts directory can be used to hardcode a specific python install's path into the .app bundle's executable shebang.
ProperTree crashes on Big Sur (macOS 11)

As of macOS 11.2 (20D5029f), the system's tk installation appears to be fixed, and works correctly. As such, it should not require an external python version to function.

This is due to the default python installs on macOS leveraging an older tk version - which lacks support for macOS 11. To solve this, you can download and install the latest python 3 version from https://www.python.org/downloads/mac-osx/ (note: Currently the "universal" 3.9.1 installer causes theme issues and should not be used) then leverage the buildapp-select.command from ProperTree's Scripts directory to build a .app bundle that will leverage that python version.

If you already have python 3 installed via brew or another package manager - it is likely still linking to the system tk version, which will still have issues unless linked against a newer version.
buildapp-select.command Usage

An example of the output of buildapp-select.command is shown below. It will walk the output of which python and which python3, then attempt to load the tk interface while keeping track of which work and which fail. The example below is from macOS 11.2 (20D4029f) with the system versions of python 2 and 3, as well as python 3.9.1 installed from python.org. If there's an existing ProperTree.app in the directory above the Scripts folder, the shebang of that app will be located and served up as the C. Current option. At the following menu, I would select option 3 or C to use the non-system python install.
