I’m thinking of upgrading to the latest Mac OS. Will Dorico 5 work without any issues? Please advise.
I’m running Sequoia 15.4.1. Works fine.
Sequoia has been out since September last year.
Dorico released version 5.1.60 on 9 October, to provide official support for Sequoia. There have been two updates for v5 since then; plus version 6.0. No doubt there will be more updates!
I’m not aware of any problems specific to Sequoia (e.g. that aren’t also on other OS versions), but you can be sure that the team will fix them, if there are.
Just realized 15.5 is out. Updated and Dorico seems fine in it too.

Thank you for the quick information. I am currently using Sonoma, and Dorico is running without any problems. I upgraded NotePerformer 4 to 5, and I don’t know if that’s the reason, but the system data on the storage has ballooned to 1.5TB, so I thought I should first update the OS to deal with it.

How big is your disk? 
How much free space do you have?
Apple’s information in System Settings > Storage is not always trustworthy, and no one really knows what falls in the “System Data” category.
See if a restart changes it. Some of that data is “purgeable”, and will be deleted if more space is needed.
Thank you for your advice. Of course I restarted and shut down the computer, but there was no change. The storage is 2TB. When I look at it from Finder, the system folder is 500MB, but the system data is only 1.5TB, which is a huge difference, and I think it’s strange, even though I’m an amateur. I deleted as much as I could, but the free space hasn’t increased at all, so I think this is abnormal.
I would recommend using a tool like OmniDiskSweeper, or DaisyDisk, which can sort your disk by file size, and show you what is using all the space.
I’m not too keen on so-called “Cleaner” or “Sweeper” apps, which can often do as much hard as good.

Thank you for your advice. A famous DTM site in Japan recommends cleanmymac in a comprehensive sense, so I’m going to try it out.
A lot of the time, they just delete temporary files, which the OS needs, and just replaces.
A few years back I was advised by a Mac assistant in a call to avoid using Clean My Mac for exactly the reasons Ben’s just given - it does more harm than good.

I wouldn’t recommend upgrading your OS to fix this.
I’m assuming from what you’re saying that you’ve been using the Mac storage management app to see what’s going on. If not, explore what’s going on with that.
Try removing NP5 first - there’s an uninstall app for it. Someone has posted the location of it in this forum, in one of the Noteperformer threads, you should be able to use search on the forum to find it. I think it’s unlikely to be that though.
Make sure you keep the installer if you want to go back to 5.0.0 at some point!
Then I’d try posting a question in a Mac tech support forum.
If things are really bad, I would use Time Machine and migration assistant to restore your Mac to a point in time where everything was OK.
Don’t upgrade when you have an unknown problem!
I was using the development seed of macOS 15.5 for many weeks now and had no issues with Dorico (FWIW, Dorico 6 doesn’t give me the occasional audio engine hiccup at startup, which is good). I am seeing occasional Dorico crashes when I quit Dorico (and it is not obvious Dorico crashed; I only know from the crash reporter dialogue appearing), but it has not been consistent. But Dorico performance under Sequoia has been fine.
Thank you for your advice. I asked a question on this forum before, and I heard that if I reinstalled noteperformer 4, 5 would be uninstalled, so I downgraded to noteperformer 4 and it’s working fine now. There’s nothing particularly strange about the OS’s behavior. The only thing is that the system data is abnormally large at 1.5TB.
Dorico 5 works fine for me (free version) on latest MacOs on a mac mini m1.
Doric 6 however keeps crashing when trying to select audio output and I get no sound when it doesn’t.
Running macOS 15.5 (24F74) the latest update, for the moment no issue with Dorico.
Please do Help > Create Diagnostic Report and attach the resulting zip file here so we can see why Dorico is crashing.
I’m pretty sure I did that. Will try again.
Kudos for installing 6 side by side with 5, not replacing it!
