Sorry for not being more thorough about the report.

<div class="">I have been using both the LuaLaTex and the lualatexmk engines. I’m not absolutely sure that crashes have occurred with both but my impression is that they have. (I’d originally suspected that a new version LuaLatTeX or SyncTeX was the problem
because the crashes began with TeXLive 2017 but I began to wonder if it was instead somehow connected with iCloud.) </div>
<div class=""><br class="">
</div>
<div class="">I’ll also note, in case it is relevant, that, very rarely, I’ve had minor file corruption: spurious characters--odd enough to produce an error in the LuaLaTeX run--appearing near but after a point I’d been editing This has happened so rarely,
only 2 or 3 times since TeXLive 2017 was available, that I’m not sure it occurred in connection with crashes. It, too, was a minor annoyance, but it was one reason I began to think that something related to saving the file may have been the issue.</div>
