Bluedepth<p>That was weird. Had <span class="h-card" translate="no"><a href="https://mastodon.social/@MonaApp" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>MonaApp</span></a></span> running, went to save a photo in my <a href="https://mastodon.social/tags/Apple" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Apple</span></a> Photos.app, and got an error, "PHPhotosErrorDomain -1" restarted both Mona and Photos, to no avail. Was about to send a ticket into the developer of <a href="https://mastodon.social/tags/MonaApp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MonaApp</span></a>, but then tried just a basic reboot of my new MBP. Poof, all fixed. What caused it? I suspect it's because I had a different Photos.app library running across a sleep/wake cycle perhaps. LOL. Illogical computers.</p>
