Yes, I need to same answer please!

I don't think so. I just bought a new computer, with Mojave, and used the backup from Time Machine to load the new one. It only brought over F25, and a couple of older versions of NP, SW, and PM. And most of them don't work, either. But it didn't ever try to install the 2012-2014 programs.

MakeMusic tells you this won't work and, if you try it, you're on your own. Finale will not install over High Sierra or Mojave before v. 25.4.1!

That said, I am running Finale 2014.5 & 25.5 over Mojave on an unsupported Mac (more on that below). I put it on my test SSD and used Migration Assistant to bring my system settings and Applications over (instead of installing which won't work). Finale 2014.5 will open for me and appears to work the same as in Sierra and High Sierra: with limitations. Some of my VIs will not load — the same ones that will not load in 25.5, Digital Performer and DSP-Q so that's not a Finale issue. 25.5 runs like a top.

I installed it on my 2010 27" iMac i7 using the instructions below.

When this guy writes  

Currently, it is not possible to get full graphics acceleration when running Mojave on a system with a Radeon HD 5xxx or 6xxx series GPU. Mojave will be almost UNUSABLE without graphics acceleration. This includes the 15" and 17" MacBook Pro systems (MacBookPro8,2 and 8,3). If you want to enable GPU acceleration on these machines, you'll need to disable the AMD GPU (This will work on MacBook Pro 8,2 and 8,3 systems ONLY. You CANNOT disable the AMD GPU in an iMac.)... 

believe it. Although it is too slow and the screen is glitchy to be practical, it does work well enough for testing.

If you upgrade to Mojave, I cannot recommend too strongly upgrading from High Sierra on a boot drive formatted APFS (not a partition!). This is so that, if you don't like it, you can revert back to High Sierra via Snapshots in a few minutes instead of many hours through an erase and complete Time Machine Restore.

I did the above Proof of Concept test to see if it was worth spending the $$$$ to upgrade to a system capable of running Mojave. I've determined it is and will be doing so soon. I last made a major purchase over eight years ago. It's time.

Thanks for this info Mike, wish I saw it earlier. I am having real problems running finale on my MacBook os 10.14 since upgrading to Mojave last Friday. I upgraded to v25. And I still have problems opening a new project from the wizard.

What sort of problems?

Finale 2014.5 is considered compatible with macOS 10.8 to 10.12. So we do not expect that you will get favorable results when using this version of Finale with 10.14 Mojave and this is not supported. 

Brenton, if you are having issues with using the Setup Wizard with v25 on Mojave, please use the Submit a Request button above and get in touch with us. We are not aware of any issues concerning this so we will definitely want to take a closer look at this with you. 

What David says. Thanks for weighing in!

Ok so I downloaded the Finale 25.5.0.259 and reinstalled it on my machine and authorized it and followed the information on the readme file and it worked. The version 25 is only launching from the Finder/ application location. Finale 2014.5 is the only icon appearing in Launchpad, not v25. 

So do I now remove 2014.5 from my machine? And if I remove it how do I get v25 to appear in Launchpad?

Having said that the worst is over, I can now start a new document using setup wizard.

Really?

Having upgraded to MacOSMojave Version 10.14 and my Finale to 2014.5.7098, I'm also having problems with Setup Wizard crashing. 

It won’t work. You can run 25.5, or 26, but nothing earlier in Mojave.

Having said that, if you read Mike Halloran’s post a steps up, you will see that it may be possible, but it’s not supported, and you’re on your own.

I'm finding it difficult to follow this thread. At the risk of asking a redundant question:

My Finale 25.5 is excruciatingly slow since my recent Mojave 10.14.1 upgrade. Will reinstalling Finale 25.5 fix this? 

- Shawn

Plain and simple: Probably not. If it doesn’t run now, reinstalling will, most likely, not help. On the other hand, you lose nothing by trying.

Download the demo version of 26, and see if it’s better. You could also open a help ticket with Finale. Use the Submit a Request tab at the top of the page.

Thank you Mike Rosen. 

Since upgrading my Mac to Mojave, my Finale has developed a lot of 'quirks' . . . I have to restart after the program has been open a while, and sometimes shut down completely.  I have never been complete happy with Finale and Mac - but have managed .  But lately this has been quite annoying!  I am wondering if Sibelius has these problems with Mac  ???

Thank you, Nancy

I was having issues too. I contacted Finale and the instructions below made everything work better, except for the resolution, and you might just try the resolution "solution" first, so I'm highlighting that instruction at the top:

• Launch Finale in low resolution mode by following the steps in this article: Slow performance on Mac Retina displays and see if the issue has been resolved.

• Close any open applications
• Open a new Finder Window
• Choose Go > Applications from the Finder Toolbar at the top of the computer screen
• In the Applications folder, find your "Finale" icon and drag it to the Trash
• Locate any "Finale" icons on your Dock and move them to the Trash as well
• In the Finder program toolbar, choose Go > Go to Folder
• Type or copy & paste the following location:
  • ~/Library/Preferences
• Click Go
• In this Preferences folder, find a file named "com.makemusic.finale.fprf". Drag it into the Trash
• In the Finder program toolbar, choose Go > Go to Folder
• Type or copy & paste the following location:
  • ~/Library/Application Support/MakeMusic
• Click Go
• Verify that you have no personal files in the "Finale" folder (or its sub-folders)
• Drag the "Finale" folder to the Trash
• In the Finder program toolbar, choose Go > Go to Folder
• Type or copy & paste the following location:
  • /Library/Application Support/MakeMusic
• Drag the "Finale" folder to the Trash
• Empty your Trash
• Restart your computer
• Re-install Finale by downloading it from your MakeMusic account
• Launch Finale in low resolution mode by following the steps in this article: Slow performance on Mac Retina displays and see if the issue has been resolved.

GOOD LUCK.
