Checklist (place an x between the brackets to mark as completed):

• I have made sure I am on the latest version of blobsaver
• I have checked other open issues to see if my problem has already been reported
• I have tried common troubleshooting tactics such as restarting my computer and reinstalling blobsaver

Try v3.2.1 and let me know if it fixes your issue.

Tried on v3.2.1 on Mac 10.14.6 (Intel), did not fix error. Let me know if you want the log.

I used another computer on 10.15 and got what I needed, you can close this but the problem still isn’t fixed on my personal computer.

Same here with iPhone 13 Mini iOS 15.1.1 and Mac 10.13.6 (High Sierra)
Here is the log:

Confirmed not working on my 10.14 mac, iPhone 11

It seems that when I compiled libimobiledevice in universal binaries, it lost support for macOS < 10.15. I'll have to figure out how to compile targeting a lower version.

Currently the only fix for this is to update to macOS 10.15 (Catalina) or a newer version.

[jawsoftware]

Please try this build. Let me know if it fixes it, I'll release the the fix if it works.

Sorry, it still doesn't work. When I click on "Read ECID from device" it gives the same error.

[airsquared]

OK, so this confirms that read from device works fine on 10.15 (Catalina) but not on 10.14 (Mojave).

Since Mojave is an unsupported OS and every computer that can run Mojave can also run Catalina, I don't have any plans to add support for these older versions. However, if someone would like to help add support I'd welcome a PR.

If you cannot upgrade to at least Catalina for some reason you can try one of the following:

• Use another computer to obtain device information and copy it over with File > Export Saved Devices...
• Try replacing the blobsaver.app/Contents/Frameworks directory with an older version of the same directory from v3.0.4 (untested and likely to easily break)
• If you're using Mojave for 32-bit support, you can reenable 32-bit support in Catalina
• Install Catalina or a newer version in a separate APFS volume or drive to keep your existing Mojave installation
• Try Linux in a virtual machine with USB passthrough; or install Linux on a separate partition

I know this issue is closed but I can at least say that this issue has spontaneously cleared itself up for me. I'm still running Mojave and was surprised to find my folder for my Apple TV and iPhone 7's blobs filled and up-to-date. Can't say what changed! I'm still running version 3.1.0, and I guess I'll stick with it for the time being.

edit: I can say that, in the interim, I've updated Java and many libraries. One I recall in particular is Apple's iTMSTransporter library. Maybe updating that will clear up the issue? @jawsoftware Want to give that a try? I got the installer for version 3.0.0.26 from this Apple web page.
