 # Introduction
 MQTTk is a very lightweight MQTT GUI client that looks retarded, but it does the job fast in a native
 fashion, without bloated and sluggish browser, java and javascript based rubbish that may look good, but

 ### macOS Dependencies
 You must have Python 3.7+ and pip installed. On some versions of macOS or the python package, Tk/ttk is not included, 
 in which case the python-tk package is also needed.

 ## macOS universal2 appimage
 My time and knowledge is limited to figure how to properly build a universal2 app image (intel + ARM). I managed to

+build an M1 only version, with which I'm not entirely happy, it takes a long time to start up for some reason. Furthermore,
 I had issues with the app when not running on the system interpreter on my M1 mac, causing regular crashes and
 kernel panics when switching to and from MQTTk. I would appreciate help with building the app and testing the 
 resulting image out on other machines.
