How to find crash logs for iPhone applications on Mac, Vista and XP

iTunesConnect service — a web site that iPhone developers use to manage their published applications — has a separate area that will list all the synced crash reports from the application users.

However, not all of the crashes appear there, or are slow to appear. Thus, if you have a desperate problem with someone’s application, it’s a good idea to pick these up and send them to a developer.

Here’s how, in three major operations systems: Mac OS X, Windows Vista / Windows 7 and for Windows XP.

Please note: this is a personal website, NOT a support resource for various large games and app companies that send their customers here. Use this page to find the crash logs but then contact them, not me. Please!

iTunes sync

Application crash logs are transfered to your computer each time you do a sync with the device, in the iTunes. Thus, first step is to sync with iTunes:

Sync the iPhone or iPod Touch through iTunes

Sync the iPhone or iPod Touch through iTunes

Mac OS X

On the Mac, crash logs are kept at:

~/Library/Logs/CrashReporter/MobileDevice/<DEVICE_NAME>

where ~ is your Home folder. Here’s an example:

Crash logs on the Mac OS X. Device name is "iPhone AV" here

Crash logs on the Mac OS X. Device name is “iPhone AV” here

There’s the .crash file and .plist file – archive them both and send to a developer. Actually, pick all the files you find there that have the name of the problematic application.

Windows Vista / Windows 7

Files are located here:

C:\Users\<USERNAME>\AppData\Roaming\Apple computer\Logs\CrashReporter/MobileDevice/<DEVICE_NAME>

AppData folder is hidden by default, so here’s how to access it. Get into your personal folder:

User folder, with Vista folder path

User folder, with Vista folder path

Now click on the folder (address) bar which will change the display into Windows folder path and add \AppData to it, then click Enter.

When clicked, the address bar changes into regular Windows folder path

When clicked, the address bar changes into regular Windows folder path

This will then show the folder contents. From here, you can follow the path above until you get to the crash logs.

For Windows 7, follow the same procedure.

Windows XP

Location is here:

C:\Documents and Settings\<USERNAME>\Application Data\Apple computer\Logs\CrashReporter/<DEVICE_NAME>

<USERNAME> is your login username. Application Data folder is usually hidden by default, so you need to reveal it in the same way as in Vista — by typing in and pressing Enter.

And that’s it. Easy :) – rest is for developer to sweat it.

    Thank you so so much for explaining how to fix this problem with Vista! :) it was taking my computer a very long time to transfer a purchase from my iPod to my iTunes, and so I finally found this article and it finished within seconds. Thanks!!

    Thanks for helping out a dev figure out what is buggy about their latest update.
    I love the product ( Password Maker ), but it seems to be buggy on just my model of iTouch after their latest update. Worked great before.

    I wouldn’t have been able to give the dev enough details without knowing how to get a crash report!
    Thanks!

    I have windows 7 and I have an app that keeps on crashing I have followed your steps. Computer/Os(C:)/Users/UserName/there is no app Data. Can you help me find out what to do?

  6. Aleksandar says: (Author)

    Carol, as I wrote above, “App Data” is hidden folder, so you have to click on the folder bar, and manually type in the App Data there then press Enter to open it.

    Hi,

    I am using mac. But I can’t see any folder with device name i connected in path:
    ~/Library/Logs/CrashReporter/MobileDevice/
    then how can I get crash reports?

  8. Sahana says:

    Thank you so much for this fantastic step-by-step explanation. Hats off to people like you. I will save this link.

    My brother and I have both been having crashes, but neither of us have anything in our CrashReporter folder even after following this tute. After asking my friends, they have exactly the same problem.

    Baffling.

    NOTE: FOR WINDOWS 7 USERS. This guide does not work. Go to the start menu —>Computer–>C: (also know as the C drive)—> There is an area to search this drive in the top right corner of the window. You must find out what the app is listed as in your ipod/iphone/ipad. When you have done this type in the app’s name in the search bar followed by .crash. For example if the app I wanted to get crash logs for was called Slinky I would typed Slinky.crash in the search bar.

  11. nowell says:

    For windows 7:

    c:\users\\AppData\ works

    simply goto search box — but then set to make sure it searches your C: drive. when you get the search results screen you’ll see additional search options at the bottom. One of these is “custom” — hit that then select c: as the search area.

    I typed in *.crash as the search variable.

    easy right?

    it’s better than sudo foobar –p –l –r

  12. @ Carole : the D&S folder is hidden, you have to change browser setting before !

    We made a free tool called “Crittercism” that lets you automatically see all these crash reports without having to dig around for them, and from every user that uses your app! We also do some sweet diagnostics on it so you can tell which errors are affecting more of your users.

    OK so maybe its me being a bit thick, but yes I’ve found the folder with the crash logs. Now what do I do with them?

    RESPONSE (AV): Archive and send them to the developer of the app. Not me. :)

  15. jsherk says:

    Ok, I synced with itunes (step 1 and 2) but I do not see anything about finding the crash logs!

  16. jsherk says:

    Ok, to answer my last comment and question… after you sync with iTunes then Step 3 is the section that says Mac OS X … I did not realize they were connected steps!

  17. Nate says:

    I’ve found the appdata\apple computer\ folder, but there’s no “logs” in there. The phone syncs just fine, though. Is it not collecting logs for some reason?
