Like some people here I have been bedeviled with issues when using RM7 for Mac:
freezing when windows go out of focus
freezing when using Family Search functionality
sometimes exiting without closing the underlying wine processes
crashes due to the old issue with Apple's new filesystem and Crossover/wine
poor font visibility/clarity
Yesterday I finally bit the bullet and installed Virtual Box, created a Windows 10 VM and installed RM7 on it.
The difference is amazing - no freezing or crashing, fonts look like perfect crisp cleartype fonts that
I would see on a Windows box.
I work in technology and I have used Virtual Box in the past. It took me about 50 minutes start to finish
which involved looking for Microsoft's virtual images that can be downloaded and used for free. There
is contradictory information online regarding how long the VMs will work for and whether they can be
"renewed" Some say that the Windows 7 VM can be renewed every 90 days for up to 540 days. I'm using
a Windows 10 VM because it downloaded before the Windows 7 VM. These ova files are distributed by
Microsoft for free so that developers can test their websites on various combinations of browser and OS.
Virtual Box is quite similar to Parallels, available for free on the Oracle website. Virtual Box is probably a
little more developer focused and tad finickier to install than Parallels.
So far I am delighted by how well this is working.
