All app downloaded from Mac AppStore(MAS) contain a receipt inside their app bundle (example: appname.app/Contents/_MASReceipt/receipt). MAS will scan this file to check whether the new version is available.
You can use this application (Find Any File) to search any receipt on your drive: http://apps.tempel.org/FindAnyFile/
Launch ‘Find Any File’ and search for: _MASReceipt Go through each result that you think could be the culprit, copy the receipt to your desktop as a backup, and after that delete the receipt inside _MASReceipt folder. Open MAS and let it scan for software update. If it’s still showing the wrong ID, it means that you’ve deleted the wrong receipt. Restore the receipt backup from your desktop to it’s previous location. Repeat the process until you’ve found the problem receipt.

If you’re like most people, apps take up more space on your Mac than any other kind of file. And in many cases, the biggest apps are ones that you barely use.
Luckily, it’s easy to uninstall apps on a Mac. You can get rid of them like any other file: Just throw them in the trash.
Here’s how to uninstall apps from your Mac.
Important: Uninstalling an app will erase most of its data, but some larger apps might still leave data behind on your computer. To get rid of these files, check if the app has a dedicated installer, or use a third-party program like OmniDiskSweeper.

Using Finder
1. Find the app you want to uninstall, either on your Desktop or in a Finder window. If the app is on your Dock but you can’t find it anywhere else, right-click it in the Dock and then select Options and Show in Finder.
2. Once you find the app icon, you have two options. You can:
In either case, the app icon will disappear from your Finder or Desktop, along with all or most of its data. If the app icon is still in your Dock, just click it and it should give an error message and then disappear.
And to fully delete all the data, open Trash and click Empty in the top-right corner.
Using Launchpad
If you downloaded the app you’re uninstalling from the Mac App Store, you can also uninstall it through the Launchpad.
1. Open Launchpad and scroll to find the app you want to uninstall.
2. Click and hold your mouse on the app until all the apps start to shake.
3. If the app was downloaded from the App Store, it should have an X icon in the top-right corner. Click that X, and then click Delete.
The app icon — and its data — will disappear.
