Mac OS X 10.7 Lion compatibility
Our testing of various Sibelius products on Apple's latest operating system, Mac OS X 10.7 Lion, has yielded the following results.
Sibelius 7
Sibelius 7 is fully supported on Mac OS X 10.7.
Sibelius 6
If you are running Sibelius 6, you should ensure you are running Sibelius 6.2 for the best experience: chose Help > Check For Updates to make sure you're up-to-date.
To register Sibelius 6 on Mac OS X 10.7, you must choose the Register using a web browser on this or another computer radio button on the first page of the Register Sibelius dialog. If you try to register online, i.e. using the radio button that is chosen by default when Register Sibelius opens, as soon as you click Next you will be told that there is a problem contacting Sibelius on the Internet. Don't panic: you can simply go ahead and register via your web browser instead.
Sibelius 5
If you are running Sibelius 5, you will need to update to Sibelius 5.4, otherwise you will experience a crash when showing the Mixer window.
If you encounter an error message that your serial number is corrupted, see here for the solution.
To register Sibelius 5 on Mac OS X 10.7, you must choose the Register by phone, fax or email radio button on the first page of the Register Sibelius dialog. If you try to register online, i.e. using the radio button that is chosen by default when Register Sibelius opens, as soon as you click Next you will be told that there is a problem contacting Sibelius on the Internet. Don't panic: you can simply go ahead and register via your web browser instead.
Sibelius 5 is not officially supported on Mac OS X 10.7 Lion, just as it is not officially supported on Mac OS X 10.6 Snow Leopard. However, aside from the above issues, you should find that it runs without significant problems.
Sibelius 4 and earlier
Because Lion no longer supports Rosetta, which allowed PowerPC applications to run on Macs with Intel processors, versions of Sibelius prior to Sibelius 5 can no longer run at all on Mac OS X 10.7. Sibelius 5 was the first Universal Binary version of Sibelius, i.e. the first designed to run on both PowerPC and Intel processors.
Sibelius First and Sibelius Student
Sibelius 5 Student or later and Sibelius First should all run on Lion without any particular problems, except for the issue concerning online registration (see information for Sibelius 5 and Sibelius 6 above).
Scorch
Scorch runs correctly in Firefox 5, provided you set it to run in 32-bit mode. Scorch does not run in Safari (version 5.1 or later), Google Chrome or Opera on Mac OS X 10.7 Lion.
PhotoScore and AudioScore
PhotoScore 6 and AudioScore 6 and earlier are not supported on Mac OS X 10.7 Lion, and will prompt the user for the Product ID every time they are launched.
This same problem happens in v7.0 of both PhotoScore and AudioScore but has since been fixed in PhotoScore (v7.0.2) and AudioScore (v7.0.1), which are both compatible with Lion.
Auralia and Musition
Auralia 4 and Musition 4 run on Mac OS X 10.7 with no known incompatibilities. Earlier versions of Auralia are PowerPC-only applications and cannot run on Mac OS X 10.7 Lion at all.
G7
G7 is a PowerPC-only application and cannot run on Mac OS X 10.7 Lion at all.
Groovy Music series
Groovy Music Shapes and Groovy Music Jungle are PowerPC-only applications and cannot run on Mac OS X 10.7 Lion at all.
Groovy Music City 1.4 is a Universal application and runs on Mac OS X 10.7 Lion, though it is not officially supported on Lion.
Sibelius Instruments, Sibelius Starclass, Sibelius Compass
These products are all PowerPC-only applications and cannot run on Mac OS X 10.7 Lion at all.
