Intermittent crashes on Mac

[johnnypoll]

macOS HighSierra, MacBook Pro 15" 2017 with ribbon bar

Storage as Plain Text Files Shared via SimpleNote

This has been happening for at least a year I would say, though nvAlt is so good I still use it even with regular crashes. It seems very random as to when it crashes; I might be typing something, or it may just be hanging around in the background when it bombs. My edits have been saved fortunately, but it has forgotten which file I was editing when it opens again.

I have identical symptoms and the same NValt settings. Had it on High Sierra and now on Mojave also.

As per https://github.com/ttscoff/nv/issues/278 it's probably related to simplenote sync, but that's an important feature for me to sync with my phone. Are there any other workarounds other than just turning off simplenote syncing?

[johnnypoll]

My solution was to move to The Archive, which isn't free but is very similar to (and inspired by) nvAlt and is being actively developed: https://zettelkasten.de/ It is also a breeze to switch to from nvAlt; just point it to the folder of notes.

[johnnypoll]

I also used simplenote but gave that up in order to switch to The Archive. I instead now use DropBox for sync to iA Writer on Android, which works very well.

For what it's worth, I see the same behavior when trying to run nValt on two MacBooks:

• nValt 2.2.8 (128)
• two Macs (both on High Sierra, although different minor versions)
• Sync via DropBox
• Plain text notes.

Symptoms:

1. I'll be working, and leave nValt & Dropbox running on 1st computer.
2. Switch to second computer (at home, on a different network.)
3. On second mac, I'll see a "quit unexpectedly" similar to this issue and #554
4. Re-open nValt on second mac and it will lose the latest info from the open note(s) on the first computer. Similar to #547, and maybe #321. Dropbox will often not record the lost info as a deleted note or part of the file version history.

Unfortunately, this has led to lost work. (Saving files saves to DropBox... so when second computer crashes and trashes file on DropBox.... no recourse unfortunately.)

NValt is crashing frequently on me as well

@sh00tthec0re @johnnypoll @wkrantz How frequently does it crash?

One thing to try is disabling the autoupdater from terminal: defaults write net.elasticthreads.nv SULastCheckTime -date "2100-01-01 00:00:00 +0000" Restart nvALT after this.

This setting will be reset if you check for updates manually through menu. Can be checked with defaults read net.elasticthreads.nv

Let me know if it helps, if not we can debug further.

I tried this solution but it did not work and crashed again.

Edit: I am using Catalina (10.15.3)
