Thanks, Marc. That sorts it....much more comforting. I can now go ahead and update the rest of my iMacs and my MacBookPro, which is identical to yours. Philip.

Thanks, Peter. I am using top spec'd iMacs from 2018 with 32GB of Ram, so it sounds like that should be fine.

Brilliant. Thank you.

Great. Many thanks for that. I had gathered that I needed to upgrade to the service pack. I have 3 Mac licences for VWX 2020 plus 2 for VWX 2019. Will they all work on Catalina with the latest service packs? As you can see...When I do the changeover...I need to do them all together!

Wonderful. Thank you. That's all I needed to know!

So my main question is, does anybody have VWX 2020 working properly, on Mac OS 10.15 (Catalina)? I have VWX 2020, already to go, but equally have Mac OS 10.15 Catalina, which I also have ready to go, but dare not load either, until I know that they work okay together. So currently, I am still with VWX 2019, and Mac OS 10.14 (Mojave)

I am in the same boat. I have 5 Macs running High Sierra and VWX 2019. And having purchased VWX 2020, it looks like I still cannot use it. Very frustrating not to have a definitive answer on compatibility with the latest Mac operating system with either VWX 2019 or 2020. So are VWX 2019 and VWX 2020 now compatible with Mac OS Catalina...or was VWX 2020 as wast of money? Good if we can receive an emailed update from suppliers on this.
