MacOS Sequoia local network access and the new ‘Allow [app name] to find devices on local network’ prompt

After upgrading to Sequoia a number of my installed apps sometime after the first boot popped up a prompt to ‘Allow [app name] to find devices on local network?’. Thinking this was odd I answered no for each of these and didn’t think any more of it. A couple of days later I realized I couldn’t access any websites running locally on my network, for example services running in containers on my Proxmox server. I could still ping their ips and get a response, but Chrome was saying ‘No route to host’.

After some Googling I found some posts with the same issue and it’s related to this prompt for accessing local devices. To enable the access after you’ve already answered no to the popup, go to System Settings, Privacy and Security, Local Network and enable access for any apps that need it:

Which my.cnf is mysql using?

mysql searches for your local my.cnf in a number of default places, so finding which is actually in use can be an issue.

To find which search paths are currently being used by your current mysql install (from here), use:

mysql --help | grep my.cnf

And it will show a list of paths like this:

> mysql --help | grep my.cnf
                      order of preference, my.cnf, $MYSQL_TCP_PORT,
/etc/my.cnf /etc/mysql/my.cnf /opt/homebrew/etc/my.cnf ~/.my.cnf

Note that if you installed mysql via homebrew (on MacOS), this will also show the homebrew path where my.cnf is located.

Changing MacOS keybindings for Home/End keys to behave the same as Windows

Sometimes muscle memory is hard to unlearn. I can’t get used to the Home and End keys on a Mac jumping to the top and end of a file instead of start and end of a line. Yes, I know Cmd-left and Cmd-right do the same thing on a Mac, but pressing Home and having it jump to the top of a file is too much for me to handle when in the middle of editing something in an IDE like Eclipse.

To remap the Home and End keys to behave the same as on Windows, make a dir here:

mkdir ~/Library/KeyBindings

and create a file called DefaultKeyBinding.dict (NOTE: this file must be named exactly as shown to work) containing this content:

{
    "\UF729"  = "moveToBeginningOfLine:";
    "\UF72B"  = "moveToEndOfLine:";
    "$\UF729" = "moveToBeginningOfLineAndModifySelection:";
    "$\UF72B" = "moveToEndOfLineAndModifySelection:";
}

Logoff and log back on again, and the Home and End keys should now work the same as on Windows. (source here)

If this still doesn’t work in Eclipse, it maybe because Line Start and Line End and explicitly mapped to Cmd-left and Cmd-right – these can be changed in Preferences under Keys:

Delete the existing mappings for Home and End and change to the Home and End keys:
