Hi everyone, I hope this is the right section of the forum 
I installed HA firstly on MacBook Pro Retina early 2013 with macOS Catalina (10.15.6) and all worked properly, the I decided to try move it into a Mac mini 2008 with Mac OS X Lion (10.7.5) with a 1.83 GHz Intel Core 2 Duo and 2 GB 667 MHz DDR2 SDRAM (just to say hardware is ok to run HA).
The problem is, I had to install HA with Python 3.7.6 from the portable to the remote directory of the desktop, because on the Mac mini it did not work, via terminal with the known commands:
$ python3.7 -m venv /Volumes/Mac-mini_name/Applications/Home Assistant
$ cd /Volumes/Mac-mini_name/Applications/Home Assistant
$ source bin/activate
$ python3.7 -m pip install homeassistant
There were also some problems (like SQLAlchemy v1.3.18, HA wanted 1.3.17), but the I was able to start it and reconfigure all from zero (I was unable to import integrations, something did not work).
The main problem, now, is this:
The following integrations and platforms could not be set up:
Please check your config.
Then:
“default_config:” is set in configuration.yaml and it works (“frontend:” work, for example), but if I try to insert “mobile_app:” I obtain that:
Component error: mobile_app - dlopen(/Applications/Home Assistant/lib/python3.7/site-packages/nacl/_sodium.abi3.so, 2): Symbol not found: _memset_s
Referenced from: /Applications/Home Assistant/lib/python3.7/site-packages/nacl/_sodium.abi3.so
Expected in: /usr/lib/libSystem.B.dylib
in /Applications/Home Assistant/lib/python3.7/site-packages/nacl/_sodium.abi3.so
I tried to reinstall pynacl, but nothing changed. Obviously the problem should be LibSystem.B.dylib of my Mac mini.
I tryed also to reinstall the Lion 10.7.5 Security Update 2014-004 and Mac OS X 10.7.5 Lion Combo Update, but nothing changed.
Anyone have other ideas? 
Thank you all very much…
