UnityStandaloneFileBrowser: DLL not found issue in Mac build

I solved this by building a universal bundle. To do this, I opened the StandaloneFileBrowser.xcodeproj/project.pbxproj and modified ARCHS = "$(ARCHS_STANDARD_32_64_BIT)"; to ARCHS = "$(ARCHS_STANDARD)"; and I removed VALID_ARCHS = x86_64; which when set made the .bundle created not include the arm64 slice. Finally I confirmed with lipo -info StandaloneFileBrowser output x86_64 arm64 and replaced it into the unity project.

@acgourley thank you so much!! Now work in mac m2 pro!! If anyone need it, these are the precise steps I followed:

1. In the UnityStandaloneFileBrowser folder, go to Plugin -> MacOS -> StandaloneFileBrowser
2. Show package contents of StandaloneFileBrowser.xcodeproj
3. Open the project.pbxproj file with Xcode
4. Change the line ARCHS = “$(ARCHS_STANDARD_32_64_BIT)”; to ARCHS = “$(ARCHS_STANDARD)”;
5. Remove the line VALID_ARCHS = x86_64;
6. Save the file and close Xcode
7. Go back to the Plugin -> MacOS -> StandaloneFileBrowser folder
8. Open StandaloneFileBrowser.xcodeproj with Xcode
9. Perform the build. A StandaloneFileBrowser.bundle file will be created
10. Go to the folder where the file was just created (you can find it in Xcode by going to Product -> show build folder in finder)
11. Copy the StandaloneFileBrowser.bundle file
12. Replace the existing file in the /StandaloneFileBrowser/Plugins/folder

If you had already uploaded the asset to unity, make sure you re-import it after replacing the bundle file, before continuing with the project

Would you be able to upload/send your latest bundle file for us to use? It would be super helpful. Thanks!

Sure! Here is the plugin with the added compatibility:

UnityStandaloneFileBrowser_arm64.zip

Unfortunately, some bugs still persist as mentioned by @hippogamesunity, but in any case, with this upgrade the system file browser is correctly loaded in macos. Therefore, in my opinion, this free plugin remains a valid alternative to other paid plugins.

We need a true mac dev as there is source code available) I’m not, unfortunately.

This project is abandoned. The asset has a few critical bugs on Mac, like app crashes when you press Cancel in File Picker. I’ve purchased another asset and it works fine https://assetstore.unity.com/packages/tools/utilities/file-browser-pro-98713

I’m not sure if we can include both original and fixed bundles.

Tested x64 architecture only + Core i5, it doesn’t work (missed DLL).

Ah typo in that filename, it’s this one: https://github.com/gkngkc/UnityStandaloneFileBrowser/blob/master/Plugins/MacOS/StandaloneFileBrowser/StandaloneFileBrowser.xcodeproj/project.pbxproj

In my case, Build Settings>PC, Mac & Linux Standalone > Architecture > “Intel 64-bit” works fine in my M1 mac and my old i-mac using Unity 2020.3.9f1.

Unfortunately I get same error messages setting “Apple silicon” or “Intel 64-bit + Apple silicon”. Even though I rebuilt StandaloneFileBrowser.bundle on Xcode of M1 mac, I cannot fix this issue now.
