[MlMt] MailMate on one machine not syncing

Post by Steven M. Bellovin
On my desktop (an iMac running Mojave and up-to-date MailMate 2.0), it
often doesn't seem to wake up and sync. The machine is not sleeping;
not only have I verified that in Settings, I've used another machine
to monitor packets coming out from it. (What I see, of course, are
primarily broadcasts.) This is quite annoying because it's also my
SpamSieve machine. It's not filtering my inbox, except for a few times
a day, nor is it looking at the remote good and bad mailboxes. It was
never great at sync, but it's gotten much worse. I don't know if it's
the Mojave update or the fact that my primary mail server was down for
a few weeks until I could bring up a Linux box to replace my
superannuated Mac Mini. But that happened more than a week ago and the
new mail server is working fine.
Any thoughts? (I have some of the mailboxes with the synchronization
schedule set to "connected"; it hasn't helped.)

I think it is likely to be related to the so-called app nap feature in
macOS. I'm not sure whether or not it got “worse” on Mojave, but
I've got some notes on what I need to change in MailMate to (possibly)
avoid this problem. I'll note your address for testing such changes.

Ah! I'd never even heard of that feature. Following the instructions in
https://www.lifewire.com/control-how-mac-applications-use-app-nap-2260788
I've tried turning it off system-wide; I'll see if it helps, though for
all I know I have
to restart MailMate after doing that.

I don't think Apple allows it to be disabled like that any longer, but I
believe I've solved the problem within MailMate now. Hold down ⌥ when
clicking “Check Now” in the Software Update preferences pane to get
a test release.

Installed 6130; I'll see what happens. (I was expecting to see the
setting in the
app options—is that only for releases prior to Mojave?)

Apple removed the App Nap setting in the “Get Info” menu if that's
what you mean. I'm not sure which macOS release, but I think it was
before Mojave.

Yeah, it's not there in High Sierra either.

As a followup: this did completely solve my problem.
