Pretty straight forward…
**On Windows folders are sorted together at the top of the file list before their sibling files in the same folder.
I have found the Finder setting to accomplish this, which works for Finder, but it has no effect on how Unity operates**: Sort Folders and Files on Mac Just Like Windows With a Single Setting Switch
I also found a forum post from 2013 with an extension that is designed to fix this. However despite fixing the missing “&” symbols in the script, it still does not seem to work: https://forum.unity.com/threads/project-window-extension-script-folders-sorting-double-click-expand-collapse.180186/
I ALSO found a Unity Answers question on this from 2015, to which the first response came from me, today, 4.5 years later: https://answers.unity.com/questions/991484/project-view-folder-grouping-in-osx.html
REALLY hoping someone can help me out here because it’s driving me insane.
i’m also looking for the same thing. this folder-file sorting is killing my production speed.
Sorry to raise this post, but had to tweak some of the code to get it to work, thought I would share.
thank you @WeslomPo for the original!

Hi @NMD83 ! How are you?
So, problem lay here
// not actually code
// foreach browser in UnityEditor.ProjectBrowser.s_ProjectBrowsers
// browser.m_AssetTree.data.foldersFirst = true
// browser.m_ListArea.foldersFirst = true

"The script above was breaking every time anything reloaded and you’d need to click something inside the project folder for it to sort.
UnityEditor → ProjectBrowser → GetShouldShowFoldersFirst() → right click → Edit IL instructions → replace instructions with “ldc.i4.1”, “ret” (meaning ‘return true;’).
