I'm on an iMac using 10.14.3 (will be upgrading soon) and using Python 3.7.3. I'm using Blender 2.91.2 and the installed Python with Blender is 3.7.7. I have concerns about Blender installed Python (that I've asked about here) and am wondering if I'd be better off just using my system version of Python. I understand all I need to do to make that work is to rename the Python directory in my Blender folder.
My concern is what that changes. Is there anything special about the version of Python that comes with Blender? I know it's a newer version than on my system, but I would think, since they're both 3.7.x, that shouldn't be a big issue.
What kind of consequences will I have to deal with if I use the system install vs. the Blender install? Are there disadvantages to using the system install? My main reason for doing this is because I am adding modules to use in Blender scripting and I know that when I install PIP and other modules in the Blender Python, I'll have to redo those every time I install a new version of Blender.
I'd rather just use the system Python, since that involves less work when I upgrade Blender (just changing the Python directory in the Blender folder), but I want to know what consequences to expect before making that change.
