SavvyCAN “Save” crashes Mac OS 10.13.6

[TessieCatEC]

Hi Collin, I am trying to save a SavvyCAN data string (frame?) but each time I select “Save” (using any of the 3 Menu->File-> “Save” buttons) SavvyCan crashes the application back to the desktop. I then tested and found that ALL items in the “File” menu cause the Mac OSX system to crash. I have over 16GB available space and I am only trying to save a few minutes of data from a MrDIY device using his CAN shield with an ESP32 and is loaded with an open source project called ESP32RET.

SavvyCan is running on Mac OS 10.13.6 MacBook Air. I tried re-downloading the dmg but it made no difference.

Everything seems to work fine with Wi-Fi connection (GVRET). Data flows in… After just a few minutes I “Suspend Capturing” and then use Menu->File->(Any selection). Instantly, “poof”, app has crashed back to desktop. An Error window displays to send to Apple. I have attached the Apple Error document.

Am I doing something wrong? I am just trying to make a CAN data string file to send to someone who can debug a CAN bus problem I am having. Thanks so much for your help. [email protected]. 614-562-7979 txt/cell

It appears that the issue is that dylibs are being used that expect a MacOS version of 10.15 or higher. And, since you're using 10.13 this is not satisfied and it dies. Here is the actual crash reason:

Dyld Error Message:
Symbol not found: ____chkstk_darwin
Referenced from: /Users/USER/Desktop/SavvyCAN.app/Contents/MacOS/../Frameworks/
libpcre2-16.0.dylib (which was built for Mac OS X 10.15)

So, if you can upgrade to 10.15 then it might work. However, I am noticing that you're using an older MacBook Air and have only 4GB of RAM so maybe 10.15 won't work. I use OpenCore Legacy Patcher on my MacBook Pro 2013 to run MacOS 14.3 even though it is not supposed to run anything newer than MacOS 10.15. However, you might be able to use OpenCore to get up to at least 10.15 so that it works. Though, I suppose I can't promise that it'll work even then but I know it does work on MacOS 14.

Thanks for your help. I purchased a newer MacBook Air with OSX 12.6.1…. All the File -> Menu options now work as anticipated. Thanks again.
