Customer Question

I have Sibelius 8 and it is vey unstable in many ways. For instance when I choose a tab from the ribbon such as Text Play Layout etc. the choice doesn't stay chosen but has a tendency to jump back to an earlier choice. I may have to make the choice several times before it stays chosen.

Hello, my name is***** to Justanswer! Give me just a few minutes to look up some specifics, I'm working on this now.

Expert:  Rusty replied 9 months ago.

Sometimes RAM is the only issue with an Avid product. Give me the full details of your computer, and your interface that you are using.

Expert:  Rusty replied 9 months ago.

I see the problem. Sibelius 8 only works with 10.9 or 10.10. The rest of your computer is compatible. You're seeing bugs that weren't built for your OS version.

Customer: replied 9 months ago.
is Sibelius being upgraded for the later OS?
Expert:  Rusty replied 9 months ago.

Avid does not have qualification to write their programs for 10.12 yet. Your best bet is to revert back to the earlier versions in the meantime.

Do you know if a monthly subscription to Sibelius covers use on a Windows machine and if there are any compatibility issues with Windows 10?
Expert:  Rusty replied 9 months ago.

Yes, the 64 bit versions.

64-bit Windows 7 (SP1 or later), Windows 8.1 (not Windows RT) or Windows 10

Expert:  Rusty replied 9 months ago.

Click here for all of the compatible versions.

Please don't forget to rate 3-5 stars for my knowledge and service to you.

I took your answer at face value but, after checking again I find that, according to various sites (e.g.,, this answer is not correct. "Sibelius macOS 10.12 (Sierra) is supported with Sibelius 8.4.2". Thus, your answer is not acceptable and I either need a satisfactory answer or my money back.
Expert:  Rusty replied 9 months ago.

I sent you right to the Avid site.

You said you had Sibelius 8. You will need to downgrade your OS, or upgrade Sibelius to 8.4.2.

Customer: replied 9 months ago.
I have Sibelius 8.4.2. When I was asked what version of Sibelius I had, I answered Sibelius 8 just like I'd say I had Windows 10 in answer to a similar question about Windows.
Expert:  Rusty replied 9 months ago.

That's not Sibelius 8 when we're talking about software... I'll opt out, good luck.

Customer: replied 9 months ago.
What does that mean? Do I get my money back?
