Apple's Photos for macOS taking forever to scan photos for People?

I recently migrated around ~50,000 photos and videos from Aperture to Photos (see my blog post on the process), and have also in a short amount of time upgraded my personal and work Mac laptops (both from older MacBook Airs to newer MacBook Pros).

On both of my new laptops—which were at least 3x faster than my older Airs—I noticed that Photos started completely fresh in its photo analysis for the 'People' album that shows everyone's faces. And after three weeks of seeing one of my CPUs stick around 100% all day every day (while plugged in), I started getting sick of this.

I would leave the Mac on all night, and check in the morning, and only 20-30 new faces would be recognized.

I made the switch from Aperture to Photos

Aperture to Photos macOS Sierra upgrade and migrate library using iCloud

tl;dr: ~600 GB photo library, took ~3 weeks to migrate, some things are awesome (access to all my photos everywhere, on any device), some things less so (faces don't get synced, no loupe, no five-star rating system, no pro-level editing/batch workflows). All-in-all, I wish Apple didn't ditch Aperture... but it's not the end of the world moving to Photos.

There are many, many photographers who were disappointed Apple decided to discontinue Aperture development. Aperture was by far my favorite tool for both organizing and manipulating RAW photos taken with my DSLRs. It was fast, it had tons of great organizational features, and was highly adaptable.

Fix macOS Screen Sharing frequent pauses or freezes

Ever since upgrading my Macs to macOS Sierra, there have been one or two times when using Screen Sharing (as part of Back to My Mac) when the session would freeze up, or intermittently pause. It seemed that every 5 or 10 seconds, there would be 10 seconds where the shared screen would stay frozen.

I could enter keystrokes, but things like pasting or clicking was hit-or-miss. This made it extremely annoying to work on one of my headless Macs (without a monitor plugged in), because I could only do work in brief spurts!

I opened up the Console app (in Applications > Utilities) to see what was happening, and quickly found that the following three errors were logged any time the screen would freeze:

Apple giveth, and Apple taketh away — the Escape key

In Apple's 10.12.1 macOS update, the file 'ApplePaySplashSA.tiff' seems to spilled the beans on Apple's new MacBook Pro's (and possibly other laptops') contextual function row key replacement. I'm guessing this change won't make it's way to Apple's Magic Keyboard for some time... but for users of Apple's laptops, having a 'software-defined' escape key might be a pill that's hard to swallow.

Remapping the Caps Lock key to Escape in macOS Sierra

Update: As of macOS Sierra 10.12.1, the Caps Lock -> Escape remapping can be done natively in the Keyboard System Preferences pane! To remap without any 3rd party software, do the following:

  1. Open System Preferences and click on 'Keyboard'
  2. Click on 'Modifier Keys...'
  3. For 'Caps Lock (⇪) Key', choose '⎋ Escape'
  4. Click 'OK'

(See screenshot for reference).

For the past three years, I've used the Mac Development Ansible Playbook to automatically configure all my Macs, so they have the same applications, utilities, and preferences at all times. One of the most important tweaks I use is the combination of Karabiner and Seil to remap a few keys and to increase the key repeat rate.
