2.5 crashes on Mac OS 10.11.6

[Andrew Sellergren]

I tried both replacing the application in the Applications folder as well as deleting it entirely and re-installing. I blew away the ~/Library/Mnemosyne directory too (or at least backed it up elsewhere). The application shows an icon in the dock and then quickly disappears.

I forward this to our Mac developer, but I'm afraid he's on holiday for two weeks now...

No problem, it's not urgent. I may try out the Windows client while I'm at it.

Hey Andrew, thanks for reporting!

I've just cleaned my machine and redownloaded the Mnemosyne app and it works for my setup. I'll need to get more details on what's different about your setup that's causing this issue for you.

To start, could you post what version of macOS you're running?

Second, could you open a Terminal and run Mnemosyne via the command line and then copy-paste the log output into a terminal? That would help a lot too.

    cd /Applications/Mnemosyne.app/Contents/MacOS
    ./Mnemosyne

Finally, if there's an error message window that pops up when it crashes, you could include the text from that too, although I generally don't get much from that.

Send that along and I'll try my best to figure out what's going on.

Hey Devin,

Sure thing, no problem!

I'm running 10.11.6. The command line error message I get is pasted below.
Let me know if there's anything else you need!

OK, taking a look at this, it looks like this issue is happening because I run macOS Sierra (10.12) and Xcode 8 (I think) and apps built with pyinstaller aren't compatible with older versions of macOS than what they were built on.

https://github.com/pyinstaller/pyinstaller/issues/1191

This also seems to happen with other software.

I think trying to resolve this issue is out of my pay grade. I think the only solution available is "upgrade to Sierra". Sorry that I'm not more help, but I really am out of my depth with this sort of error. It's enough of a challenge to get the software to build!

If you'd like to try building the software manually on 10.11, it'll probably work. If it does, we could even post your .app bundle on source forge for others using 10.11.

When 10.13 is released I definitely will avoid upgrading to ensure better compatibility. I used to stay one version behind but I got a new computer recently :\

I'll also email Peter to get the website updated to say it's built on Sierra, not Mavericks!

[Andrew Sellergren (asellerg)]

Thanks for digging into it, Devin. I probably won't build it myself since I
switched to the Windows app anyway. I appreciate your effort though!
