Dorico 5 doesn't run on Mac OS 10.14.6?

I don’t really have in mind to update the operating system “only” to run Dorico 5. The collateral damage is too great, as I would have to buy certain programmes again whose (expensive) 64-bit version offers me no advantages.

I’m afraid that Qt - the UI toolkit that Dorico uses - no longer supports macOS 10.14.

Thanks for the quick answer. Can you tell me what Qt - UI Toolkit means, whether this is decisive for the “normal” use of the programme?

Dorico is completely reliant on Qt. It’s used for its entire user interface. You can’t use Dorico without Qt. Dorico 5 will not run on macOS 10.14, I’m afraid, and there’s no way to coax it to do so.


As a macOS app developer, we want to persuade app users to upgrade to as latest OS versions as possible. Developer toolchains provided by Apple are extremely hostile towards earlier versions of macOS. Sometimes, even if things look right in Xcode when you compile for older macOS, it actually malfunctions in certain rare cases when running on the target macOS. Both interface builder and SwiftUI are typical examples of such. Also, Swift async is only available since macOS 10.15 Catalina since it is implemented in kernel level inside the macOS. So does Swift concurrency since macOS 12 Monterey (except that concurrency support is providable as an additional library for macOS 10.15 and 11).

I really suggest an update towards at least macOS 12, considering the massive innovative changes among the system APIs inside macOS. These changes are benefitial for developers, helping them make their work easier to develop better softwares for their users / customers. However, they only make pains since Apple seldom downport their new APIs backwards to older releases.

Now I can fully imagine how a big shitload it will be to backport the latest Qt towards earlier macOS releases. It worths nothing.

(This reply is a sequel towards my first reply in this thread.)

Thanks Richard, Daniel and Shiki for trying to get me to upgrade the operating system. It would cost me about €1,500 to follow Apple’s dictates. So I will stay away from the Steinberg customer list for the time being. Too bad.

You don’t really have to buy the latest model of the year.
What’s your current model? Do you have minimum personal requirements of the hard disk size and the running memory size? Do you prefer mac mini or a laptop or an iMac?

Maybe you can cost much cheaper.


I think Stentor was talking about software that he would need to reinvest to.
I myself am in a similar situation.
My expensive document scanner (which works wonderfully) will have to be replaced, a unique scan tool will be obsolete, so will be another software I use on a daily base. These are the only reasons I am still on macOS 10.14…
Luckily Dorico 5 has not changed anything dramatically in the engraving area compared to version 4, so I will get some extra time to wait… and decide…

Have you tried VueScan?


Thanks Ben, I just checked and, yes this seems to work: Fujitsu ScanSnap S1500M Scanner Driver & Software | VueScan Scanner Software
I knew VueScan from decades ago and had even used it then. I’ll give it a go :slight_smile:

My current model is iMac 2017/16 GB/500 GB/27-inch. The problem is a Software (RagTime DTP) a 32-Bit Version. The Update to 64 Bit-Version 7 costs € 1’228.-! I have a huge amount of documents in this format since I’m using this software for decade(s). The costs of a new computer are still not included.

Even if no dramatic changes were made in the engraving area, I would have been very interested in the scrub option of Dorico 5.
