fix: touch app bundles after icon changes

[ZuBB]

for some cases/apps folder/bundle need to be touched so system is able to notice a new icon

ps: issue itself was debugged and coded with help of ai-based coding tools

Thanks, @ZuBB: Can you detail the cases in which touching is necessary?
Which macOS version(s) is/are affected?

Thanks, @ZuBB: Can you detail the cases in which touching is necessary? Which macOS version(s) is/are affected?

I will provide as much info as I can, but I need to be honest and admit that I do not fully understand the issue

some details:

• os version: mac os sequoia 15.7.7;
• its a corporate laptop with MDM and all that stuff. Whole MS apps suite is brought by provisioning profile (I am not sure if this is related);
• app that I am used to have trouble with it: MS Edge;
• app that I do not have issues with MS Outlook.

very short steps to repro:

• set custom icon with help of fileicon;
• wait till Edge get notification about update;
• at this moment app losts custom icons and uses 'default folder' icon;
• restart it
• (re)set custom icon
• nothing change, app still uses 'default folder' icon;

I have running modified version of the app (fileicon) for smth like 3 week (ms edge got a 3 updates) and setting custom icon each time after update works smoothly.

I hope this helps

Thanks.

I just tested with an .app bundle, and it seems that a target folder (irrespective of whether it is an .app bundle or a regular folder) is implicitly touched with the current fileicion version (v0.3.5.), so I wouldn't expect an explicit touch call to make any difference.

In other words: It's unclear to me why your PR would result in different behavior.

[ZuBB]

I understand your point

If you want I can revert my changes, wait for the next update cycle, and do some tests/checks. Or not.

In cany case I hope this PR can stay open so it may be useful for other ppl

[mklement0]

If you don't mind further tests to get to the bottom of this, please go ahead.

Either way, I'm happy to keep your PR open.

I was able to recover/reexport my thread on this issue. maybe you will be able to get an idea what was the real issue. cause I still have only guess(es)

Thanks; I've read through that chat.

Given that you're running an old version of macOS (Sequoia, v15) and I don't see the problem on Tahoe (v26), I'm hesitant to make changes.

Note that on Tahoe I also get kMDItemFSHasCustomIcon = (null), even though everything works as expected (Dock, Spotlight, App Switcher, Finder all show the same, fileicon-assigned icon for my test .app bundle).

I don't have access to MDM, so I don't know how that fits into the picture.

As for your fix: given that the touch is implicitly performed by fileicon, perhaps mdimport -i is what makes the difference.
As the chat suggests, consider writing a wrapper Bash script for fileicon that performs your fix after calling fileicon.
