The following is taken from a brilliant answer on unix.se. Posting it here for personal reference. The question was:

What kind of patterns can I use in zsh parameter expansion?

${var//pattern/replacement} is using zsh wildcard patterns for pattern, the same ones as used for filename generation aka globbing which are a superset of the sh wildcard patterns. The syntax is also affected by the kshglob and extendedglob options. The ${var//pattern/replacement} comes from the Korn shell initially.

I'd recommend enabling extendedglob (set -o extendedglob in your ~/.zshrc) which gives you the most features (more so than standard EREs) at the expense of some backward incompatibility in some corner cases.

You'll find it documented at info zsh 'filename generation'.

Force brew to install pre-compiled binary bottles on older versions of macOS (Mojave).

This patch makes a small modification to Homebrew allowing you to "spoof" or override its perceived macOS version. Often compiled bottles will work fine on older unsupported macOS verisons and using a bottle means you don't have to compile a formula from scratch or download and compile its build-only dependencies.

Of course you shouldn't do this unless you're very familiar Homebrew internals and understand the limitations. Things make break in a very confusing way. Most users should just keep macOS up to date, but for those that can't this patch may be helpful.

To use, first download and install the patch:

$ cd "$(brew --repo)"
$ wget "https://gist.githubusercontent.com/varenc/47c4b22e2b8c5afabce556645a90801d/raw/homebrew_override_version.patch" --output-document=/tmp/homebrew_override_version.patch

MediaPlayer logging:

defaults: {
    "com.apple.homesharing" =     {
        HSConsoleLoggingLevel = 7;
        HSLogFileLoggingLevel = 7;
        HSLogging = 1;
    };
    "com.apple.medialibrary" =     {

tl;dr; Run sudo launchctl stop com.apple.cmio.VDCAssistant to unfreeze your apps while using a Studio Display on macOS Catalina.

If you try to use Apple's new Studio Display on macOS Catalina 10.15.7 you end up with horrible app freezing problems. Apps like Chrome, Discord, WhatsApp, Zoom, Messenger, etc, are all freezing once a Studio Display is plugged in.

As someone pointed out on this thread, the "VDCAssistant" process seems to the source of the problems. This process is just related to managing video cameras for Apple services. And apparently disabling it fixes the app freezing issue!

So to fix the issue, just temporarily disable VDCAssistant by running this command in a Terminal:

	### This is a fixed version of the macOS zsh completion script for the `open` command.
	### See my response here for a description of the bug:
	### https://stackoverflow.com/questions/59865427/zsh-hangs-on-open-application-tab-autocompletion#63097652
	###
	### tl;dr; The original completion script is provided by Apple and not-editable by the user without disabling SIP.
	### It has a bug in it and doesn't use the Spotlight index to list applications. This makes auto-completion
	### for the command "open -a ..." very slow/impossible.
