I’m new to Chimera X, so I am probably doing something wrong. Hope you can help please.

I have ‘installed' either v1.3 and, more recently, 1.4 on my Macbook Air (under OSX 10.15.5; 1.1GHz processor, Intel Iris Plus Graphics 1536 MB).

Whilst I can run Chimera X fine (the first time after ‘installing'), it doesn’t appear to be installed locally on my laptop (that I can find).
If I close the App and try and reopen in, it’s not local, and I have to run the Install .dmg every time I want to ‘run’ it, which takes an age.
