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:

RetroPie / EmulationStation – Rotating output to the Raspberry Pi 7″ LCD 90 degrees for portrait orientation

If you are running RetroPie on a Raspberry Pi 7″ LCD, running some games e.g. arcade games using MAME, in the usual landscape orientation means the output of the game is only displayed in the center of the screen.

There are a number of options for rotating output to the screen, depending on what you need to do and/or your preferences:

Rotate the video output

You can do this by editing /boot/config.txt and adding a line like:

display_rotate=1

or

lcd_rotate=1

(depending on whether you are rotating HDMI output or output to the 7″ LCD). 1=90 degrees rotation, 2=180, 3=270

Rotate all Retroarch output

Edit /opt/retropie/configs/arcade/retroarch.cfg and add:

video_allow_rotate = "true"
video_rotation = "3"

Use a rotation value of 1, 2, or 3 etc same as rotating the video output. From here.

Rotate individual MAME rom output

In your ROMs folder, create a rom-name.zip.cfg file and add the same 2 lines as above. Same approach as the overlay configs created here, which also has config for adding a rotated background graphics overlay too.

Rotate EmulationStation display

To rotate the EmulationStation gui you can pass the –screenrotate option in the autostart config for EmulationStation, which you can either set in the cfg file directly or via the RetroPie-Setup.sh – described here.

For the 7″ LCD these options worked for me:

--screenrotate 3 --screenszie 480 800 #auto
