@Hanly-Wijaya are you using the Xcode 13.0 beta? You'll need it.

(I would post a pre-patched Maps.app, but don't want to get into trouble with copyright)

Here's a precompiled dylib if you can't get Xcode working: https://drive.google.com/file/d/1M2pRFCwHrzlqvfLSCaSH6sVlF6aXw6SQ/view?usp=sharing

These instructions create a new Maps.app on the Desktop which is patched. The author of the gist mentioned that it was possible to instead patch the stock Maps.app in /Applications, instead of making a second one on the Desktop. Given that I have SIP disabled, how would I go about patching the stock Maps.app instead?

Also, the patched Maps.app on the Desktop, which this process creates, quits on open when double clicked to open. To launch it, I must re-run the final Terminal command. Is there a way to have the final Maps.app launch without crashing with just a double-click, without using Terminal to launch each time?

2 Options: You can patch the System Maps app in /Applications or you can automate the final command with an Automator Application, a Shortcut or any number of other automation tools for Mac. This automation option is preferable for anyone who doesn't want to turn off SIP.

Patch the System Map App:

System Integrity Protection (SIP) must be turned off.

Assuming you've done steps 1 & 2 from the previous instructions to compile, run the following commands:
4. cd /
5. cd Applications
6. codesign --remove Maps.app/Contents/MacOS/Maps
7. DYLD_INSERT_LIBRARIES=../Users/YOUR_USER/Desktop/libmaps_inject.dylib Maps.app/Contents/MacOS/Maps where YOUR_USER is replaced by your user name, such as ../Users/Jake/Desktop

I have not tried this as I don't have SIP turned off, but it should work

when you turn SIP on it restores the default version? Thx!

Yup, I used Xcode 13 beta. I'll try the file you linked! Hope it goes well!

It worked! Thank you!!

any idea how to get SharePlay for FaceTime for intel-macs

Thank you for the solution.

On Ventura: 3D globe view is still fully functional, but 3D city maps seem to crash every time you zoom in to a city with that feature, i.e. San Francisco, Paris, London etc. Hopefully there is still a fix for this.
