App icon in .dmg at some sizes incorrect

[ivanmaeder]

• Version: 7.15.2

• Target: macOS

Really strange issue, I can't find any help anywhere or references to the same issue.

The build is fine, except in the generated .dmg, in the window that shows the app icon and the icon to the applications folder, the app icon is shown with the default Atom icon... but only at certain sizes!

When you open the .dmg the app icon is shown with the Atom icon, but using the slider to resize the icons, at the smallest size the correct icon is shown, and at larger sizes. Here are some screenshots:

The icons are generated by creating an .iconset dir and then using iconutil.

I've checked the original .png files again and again and these are the details:

Filename	Size	px/inch
icon_16x16.png	16x16	72
[email protected]	32x32	72
icon_32x32.png	32x32	72
[email protected]	64x64	72
icon_128x128.png	128x128	72
[email protected]	256x256	72
icon_256x256.png	256x256	72

icon_512x512.png	512x512	72
[email protected]	1024x1024	72

The actual .app that is generated in the dist/ folder has the correct icon. Changing the zoom in Finder to see different sizes of this icon is fine (the correct icon is shown in all sizes).

I tried the same with the .app extracted from the .dmg and the default Mac app icon is showing at larger sizes, with the Atom icon showing at smaller sizes:

Launchpad shows the default Atom icon.

I'm running El Capitan 10.11.6 (15G1004).

I'm running the build with npm run dist and this is the part from package.json where the build is configured:

{
  "scripts": {
    "dist": "rimraf ./dist && build"
  },
  "devDependencies": {
    "electron": "^1.4.3",
    "electron-builder": "^7.15.2",
    "rimraf": "^2.5.4"
  },
  "build": {
    "appId": "com.website.bolt",
    "extraFiles": "tools",
    "mac": {
    }
  }
}

Just to be sure the mac section is being used I added a background entry and it was used (I tried just as a test to set the iconSize field to 16 but no change was visible).

Any ideas of what I could try? Thanks!

Please see #840 (comment) Does it help?

[ivanmaeder]

Thanks @develar. Yes, that fixed part of the issue. The app icon inside the "installation" window (where the app icon is shown with the arrow pointing to the Applications/ folder) is now correct. Cool :)

But after dragging the app into the Applications/ folder, the icon shown there is the default macOS app icon.

Any other ideas?

Any other ideas?

It is macOS cache issues. Production is not affected.

OK good to know. I tried it on someone's computer that was new to the app and it all worked. Thanks!
