crashes on startup on macOS

[redmoonrose]

Anytime I open NPS Browser on macOS Mojave 10.14.4 a prompt comes up "NPS Browser quit unexpectedly".

hmm it looks like Realm is attempting to use an old schema version

[JK3Y]

@redmoonrose i'm sorry, i thought i replied with a solution to your problem! until i have the time to get to this and fix it, follow the removal directions in the readme to reset the database

[WBSpitfire]

Unfortunately this issue prevents the app from being used at all. So right now, NPS Browser for macOS is unusable and only crashes on startup.

Resetting database does nothing to alleviate the issue.

[JK3Y]

@WBSpitfire have you tried redownloading the app after running the removal commands? I still haven't encountered this issue and unfortunately I'm still busy working on NPS v3 so I don't have the time to fix this at the moment.

[WBSpitfire]

I'm sorry if I came across as hostile in my last post - I was frustrated after getting everything else set up but hitting a roadblock with this. I apologize and understand you're busy with other projects, and that this is a free software that you've made in your available time.

I redownloaded the .dmg but the same issue came up. However, I did then decide to download the dmg from a separate computer and then transfer it (after again doing another wipe from the readme instructions), and then that worked.... so I dunno. But that seemed to have done the trick.

[JK3Y]

No worries, that's strange that that solved your issue instead of deleting the database and refreshing. :thinking:

If it happens again and you get frustrated, I would recommend you just use the NPS site to download the PKG and then run it through pkg2zip from the command line. The new v3 beta site is practically NPS Browser but without automatic decryption after download.

Cheers
