When I activate the types.2.2.16. plugin on localhost, I get a 500 error.

Okay there's nothing inherently problematic about using MAMP so it's most likely a configuration issue. Can you try the following troubleshooting steps?
- Check to see if your localhost installation meets the requirements for Toolset: https://toolset.com/toolset-requirements/
- Enable server logging to see what the error is. Copy + paste anything from the relevant time period in the Apache logs. Go in your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

define('WP_DEBUG', true);

Then add these lines, just before it says 'stop editing here':

ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');

Refresh the page where you get a 500 error. This will create an error_log.txt file in your site's root directory. Please send me its contents. Once that is done, you can revert the updates you made to wp-config.php.

- Next, rename the folder at wp-content/plugins/types to temporarily disable the plugin and regain access to wp-admin. Temporarily disable all plugins and activate a default theme like Twenty Seventeen. Reactivate Types. If the 500 error returns, you've got a configuration issue. If the 500 error does not return, you probably have a theme or plugin conflict. Reactivate your theme and plugins one by one until the conflict is revealed. Let me know the results.

Here's what appears on the browser:
Fatal error: Uncaught Error: Call to a member function get() on boolean in /Applications/MAMP/htdocs/Metaglyphics/website/wp-content/plugins/types/application/controllers/interop/mediator.php:139 Stack trace: #0 /Applications/MAMP/htdocs/Metaglyphics/website/wp-content/plugins/types/application/controllers/interop/mediator.php(121): Types_Interop_Mediator->get_theme_slug() #1 /Applications/MAMP/htdocs/Metaglyphics/website/wp-content/plugins/types/application/controllers/interop/mediator.php(80): Types_Interop_Mediator->is_the7_active() #2 /Applications/MAMP/htdocs/Metaglyphics/website/wp-content/plugins/types/application/controllers/interop/mediator.php(32): Types_Interop_Mediator->initialize_interop_handlers() #3 /Applications/MAMP/htdocs/Metaglyphics/website/wp-content/plugins/types/application/controllers/interop/mediator.php(22): Types_Interop_Mediator->__construct() #4 /Applications/MAMP/htdocs/Metaglyphics/website/wp-content/plugins/types/application/controllers/main.php(137): Types_Interop_Mediator::initialize() #5 in /Applications/MAMP/htdocs/Metaglyphics/website/wp-content/plugins/types/application/controllers/interop/mediator.php on line 139

And here's the ERROR LOG

Okay this line of code is related to retrieving information about the parent and child themes, so I suspect something is going on there. Please try these troubleshooting steps:
- Rename the Types plugin folder to temporarily disable it and regain access to wp-admin. The folder is at /wp-content/plugins/types. Deactivate all other plugins.
- Activate the default Twenty Seventeen theme, then reactivate Types.
- If the error does not reappear, then reactivate and test your parent theme, child theme, and plugins one by one until the conflict is revealed. Let me know the results.
- I have a copy of the7 version 5.4.1 that I'm testing with right now and it seems fine on a clean installation with Types 2.2.16, so if the error reappears, I'll need to investigate further by making a clone of your site.
