You can get Finale 27 by buying the Crossgrade to Dorico Pro 5 for $149.  It's bundled with that crossgrade.

Thanks so much for replying to my post and for that great news, Nathaniel! I'm VERY relieved to hear this. And I'm grateful to Make Music for changing their policy instead of leaving those of us who had not yet installed v. 27 high and dry with no upgrade path to v. 27. YAY!

A 2012 MacBook Pro will run 27 but you have to upgrade the macOS to Mojave or Catalina. I have a pair of 2012 MBPs, each running one of those operating systems. I do a lot of testing for companies—guess it’s now ok to admit that both were used to beta test Finale 27,

Dorico 5 requires Catalina:

Compatibility. Dorico 5 is supported on PCs running Windows 10 or 11, and Macs running macOS 10.15 and higher. 12GB of disk space is required, and Steinberg list a minimum RAM requirement of 8GB, with 16GB recommended

A 2012 MBP can be upgraded to 16GB RAM and up to an 8TB SSD inexpensively.

Otherwise, what Nathaniel just told you. Is correct.

Is the 2012 Model the [last] one that allows you to upgrade the SSD and RAM?

I kinda wish I had gotten one of those instead of my iMac, back then.

I think the CPU in those is fine for Finale 27 if you use NotePerformer.

EDIT:  Dual Core CPUs...  My bad.

Is the 2012 Model the [last] one that allows you to upgrade the SSD and RAM?

It’s the last laptop that allows a RAM upgrade. 2013-on have soldered RAM. The SSDs can be upgraded, however, and should before the 2017 model (before 2015 for the MacBook Pro).

With all Intel iMacs, RAM and SSDs can be upgraded—even the iMac Pro. Ease and cost vary but SSD upgrades are definitely worth it for the pre-2017 models. Besides the increased storage, R/W speeds are increased 3–6x depending on the iMac. Except for the iMP, RAM upgrades are an easy DIY for the 27” iMacs.

What iMac do you have?

I think the CPU in those is fine for Finale 27 if you use NotePerformer.

27 requires Mojave; Dorico 5 requires Catalina. Either will run on a 2012 Mac anything (not true on a 2011 or earlier without a hack). If you need to dual-boot for 32 bit compatibility, this can be done easily.

If you have a mechanical hard drive in there (HDD), you absolutely want to replace it with an SSD. A 2TB SSD, adapter bracket and correct temp sensor/tape kit and tools runs under $150 from Amazon. It's an easy DIY and your Mac will run a lot cooler. You can stick a pair of 8TB SSDs in there if you have the need. The 2012 has a second SATA bus and adapter harnesses exist to take advantage of that.
