Re: Uninstall Octave 4.4 & Run Octave 5.2

[John Williams]

Andrew,

Thank you for clarifying that for me.  

Since my email, my file menu bar has unfrozen (v.4.4), and I have since learned 
to type “octave” in the terminal window to run the new version (v.5.2) without 
a GUI.  I will be interested when the GUI version of v.5.2 is available for 
Mac.  

Quick follow up question: If I move the Octave 4.4 app to trash, will that 
leave the bulk of the v.4.4 support files taking up space on my hard drive?  Do 
I need to find the Octave v.4.4 folder(s) and delete those too? 

Thanks again!
John
