Best OSX version

[zawij]

Hi,

I am running some automator scripts on Parallels desktop VM (Mavericks) - I can run two or three with my mac pro 3,1 and there is a slight drop in performance, autoamtor get lost, their workflow crashes a lot. I want to avoid that. I am getting new imac pro, and refurbishing my macpro3,1 with some ram and gpu.

After that I want to reinstall my VM osx's that I run automators in. Automator runs some actions that make safari do some work online (put a text in a box, click buttons, repeat, etc).

My question is:
what will be the best osx version to install on VM to run that kind of automators stable, without drops of performance and still run on XXI-century websites?

Do you know what OS will be on your new iMac Pro? I suspect it will be the latest version of High Sierra, OS 10.13.3.

I don't use Parallels desktop VM, nor anything similar. Both of my Macs have SSDs, running OS 10.13.3. I am not seeing any performance improvement with this APFS business with High Sierra, but my applications run fine. One thing you need to insure is that all your third party apps are compatible with High Sierra. This link can help you with that:

The latest version of Parallels is V13.3, released on February 20th. This link has some information about it:

Here are the results of a google search of "Reviews of Parallels":

Maybe some of the later ones might help.
