I have a mid-2012 Macbook Pro. Though I know that it can run Catalina, I'm leary of trying it, due to the number of 32-bit programs that I still use. Is it possible to purchase an external SSD and attach it to my USB port, install Catalina on it, and boot from that external disk?
The reason I want an SSD is that I'm hoping that it will at least run faster than a regular drive. I've tried making a virtual (using Parallels) Mojove disk on a regular drive and it runs extremely slow. So can an SSD External drive be a solution?
If so, any recommendations as to which drive to purchase?
I have a Parallels VM on an external SSD (Samsung T5) with Mojave installed so that I can run some old accounting software on my late 2012 MBPr. It does the job quite nicely via USB 3 connection.
i have also run several different MBPs from Mojave & Catalina directly installed on a T5 and they’ve been just as responsive as the internal SSD.
