Rollback IOS GO App

Stay away from iTunes 12.7 - you won’t be able to upload IPA file from Mac/PC to iDevice. This option has been removed by Apple forcing you to redownload IPA directly from iDevice. Programs section is no longer available in iTunes and you can’t download IPA directly into your Mac. If you still want to download previous versions of any program stay with iTunes 12.6. If you are on an iPhone X, use iTunes 12.6.3 to install the app after you downloaded in iTunes 12.3.1. Its the only version which the iPhoneX can install apps.

Prevent App Store Updates

If you have auto-updates enabled on your phone, or you just dont like the red badge constantly nagging that you have an update to perform, follow these steps to eliminate that.

-Extract iTunesMetadata.plist from the IPA (it's a zip file, so Betterzip would be fine)

- Edit (with PlistEditor or XCode) and remove “softwareVersionExternalIdentifier” and “softwareVersionExternalIdentifiers” from it and save the file back to the IPA (Remote the <key> and <integer> values for each

- Sync new version with device from iTunes. If you are unable to sync, install Charles 12.6.3 using the link below

Breakpoint Problems

If Charles does not interrupt the download like in the video above, you probably will need to go into Charles and specifically set the break-point to occur. Watch the video on how to do this.

OSX iTunes Removal

OSX will complain that iTunes is a core part of OSX and prevent you from uninstalling it. Follow these steps to bypass the warnings.

  1. Navigate to the Applications folder and find the iTunes app file (/Applications/
  2. Right-click (or Control-click) on iTunes and select Get Info. Locate and click on the padlock icon on the bottom right side of the window and enter your admin password.
  3. Next, expand the Sharing & Permissions section of the window if it’s not already visible and change the privileges for “everyone” to Read & Write.

This will give us complete control of the iTunes application so that we can override the operating system’s warning and delete it.
