Mac OS Mojave bridge not uninstalled successfully

[vladimirvolek]

After I uninstall the bridge I still can see bridge installed in https://wallet.trezor.io/#/bridge.
PC restart will fix this.

@vladimirvolek can you please confirm that this bug is still present ? :)

@bosomt Still present on Catalina. Had to kill tzd manually after uninstall (hmm, it sounds like uninstall doesn't clean up everything properly?) before it started to show as not installed (or restart macOS probably).

Today I uninstalled v2.0.27 using the pkg. Uninstallation failed as reported in issue #186.

And becasue I was developing something else and was looking at tail -f /var/log/system.log I also noticed a spam of

To me it looks like unistallation broke com.bitcointrezor.trezorBridge.trezord launchd service.
I think it removed the files but didn't stop/unload/unregister the service first. And because the service had KeepAlive flag set, the system was continuously trying to relaunch it.

btw. I'm unable to reproduce it again with clean install and (broken) uninstall.

I looked at the uninstaller script and it does unload:
https://github.com/trezor/trezord-go/blob/master/release/macos/flat-uninstall/uninstall.pkg/scripts/postinstall#L14

Maybe unload is not enough in some cases:

Maybe use launchctl remove instead?
