Moving to Catalina: Keep Your 32-Bit Mac Apps Running with Parallels

Thanks so much for this good advice, Mark. It’s too bad to have to be the bearer of bad news. I guess I’m just going to have to crank up the ancient MBP whenever I have to use something in the suite, and keep my fingers crossed that it stays alive.

After updating to Catalina, I installed Parallels 15.1 and El Capitan in order to run several older apps. I especially needed to run Abyss web server, Dreamweaver CS6 and Panorama Enterprise 6 for development work for clients - even as most are transitioning to Panorama X.

The VM is working great. Once I’m settled in I’m likely to upgrade the OS to Sierra and stop there.

Does it let you work full screen? Or at least in a decent sized window?

I’ve done VMBox with SL and I think I was limited by the resolution of the OS


On my MacBook Pro, it is running full screen. I’m not sure if that’s due to something I did or if the software did it. Others on the Parallels forum are asking how to get it full screen.

That’s not a very complete answer, but for sure, it does run full screen.

FWIW, demoing Fusion I was not able to get it to full screen. I suspect it’s doable though.

Thanks! I really think my issue was the screen resolution of the OS but I never really researched it. It runs in a really small screen on a 21” iMac! I ended up putting the 2 pieces of software back on my 2008 MacBook.


Thanks for this article, Glenn. Dealing with how to keep using Quicken 2007 has been on my “to do” list before allowing the update to Catalina on my MBP. However, I’ve hit a snag. I have Mojave running in a VM, got the Parallels toolbox installed and was able to copy the Quicken app over. But, I could not find the preferences file, and the VM Quicken won’t open my Quicken data file: either in the shared folder or when copied into the Documents folder in the VM. Suggestions? I’m searching the Parallels forum for ideas, but haven’t found one yet.

I have macOS Mojave 10.14.6 installed on my host iMac running Adobe Photoshop, Illustrator & InDesign CS6. They work perfectly on my host machine. I want to update to Catelina, but want to be sure that my productivity will the the same if I try to run these off of Parallels. I installed the same version of Mojave and the same Adobe CS6 applications, exactly the same versions with all their updates.

Adobe Photoshop CS 6 worked perfectly and was snappy with no lag at all, I was really excited. I tried Illustrator - it crashes the moment to loader starts. InDesign loads much further, but crashes as soon as the desktop app loads with the open file modal.

I contact Parallels a few times, and the did a remote test to see if they can get it to work - no luck yet. We did a safe mode reboot of my boot machine, and Illustrator and InDesign worked just fine. The Parallels support member wanted to be sure it wasn’t something to do with graphic 3d rendering or something.

We tried to do a safe mode reboot of Parallels MacOS Mojave, with no luck. I tried to Enabling Safe Boot from Terminal of Mac OS X with no luck - I kept getting an error in terminal. SO no luck there.

Has anyone been able to get this working? Any suggestions? The Parallels support team have escalated my ticket, so hopefully they can solve it - but hoping someone on here has been able to solve this issue.

Thanks again for your help!

Is CS6 safe? Or are they planning to kill it off the same way?
