Informação importante sobre as novidades da linha Macintosh da Apple: novo macOS 11 Big Sur e o novo chip Apple M1

Como os equipamentos informáticos do CESEM (e dos seus investigadores) são na sua grande maioria da marca Apple, é importante os nossos investigadores terem consciência das mudanças que recentemente aconteceram na linha Macintosh da Apple. Na semana passada foi lançado um novo sistema operativo (macOS 11 – Big Sur) e, mais relevante ainda, a Apple vai abandonar gradualmente (mas rapidamente) os chips com a estrutura Intel, para os seus próprios processadores com a arquitectura ARM, que é a mesma que usam nas suas linhas de iPhone e iPad. De momento as linhas MacBook Air, MacBook Pro e Mac mini já utilizam estes novos chips. Isto tem consequências para as aplicações de edição digital de partituras (Finale – o CESEM tem a v25, Sibelius – temos a versão 2020.3 e Musescore – open source com a versão 3.5.2) e coloco aqui um resumo das compatibilidades com o novo macOS e com o novo chip Apple M1:

Sibelius

Official Big Sur status: Supported
Official M1 status: Not supported

According to Avid’s Big Sur compatibility chart, as of November 13, 2020, Sibelius 2020.6 and later is supported on Big Sur on Intel.

Senior product manager Sam Butler told Scoring Notes on November 11, 2020:

As it stands, we’re hopeful that Sibelius will run very well on Big Sur on Intel Macs. We’ve been testing it since the first beta builds of macOS 10.11, and will likely support Sibelius 2020.6 (June’s release) and later, although I don’t see any reason why builds from 2019 won’t run on it. Sibelius 2018.7 and earlier, including Sibelius 7.5, 7 and 6 etc. will not run on Big Sur.

We’ve also been testing Sibelius on the new Macs with Apple Silicon chips, and it’s going fairly well. For now, it uses Rosetta 2 (Apple’s translation layer to allow Intel apps to run on the Apple Silicon chips) and all core functions appear to work. There are a few remaining bugs that remain that’s preventing us from announcing full support, such as the web enabled pages to sharing music online, but we’re hopeful Chromium or Qt or even Apple will provide a solution soon.

Finale

Official Big Sur status: Not supported
Official M1 status: Not supported

In a Knowledge Base article updated on November 11, 2020, MakeMusic said:

We’ve been testing Finale 26.3.1 with macOS Big Sur on both Intel Macs and Apple’s Silicon development kits for several months. Throughout this time, we worked closely with Apple to address any issues running Finale. At this point in time, we’re aware of one cosmetic issue isolated to the new macOS. To our knowledge, everything else after a full Finale install looks good at this point using Big Sur on both Intel Macs and Apple Silicon Macs running Finale with Rosetta 2.

In recent years, the version of macOS that reaches the public has been known to change compared to the final beta versions provided to developers, so we’ll start our final testing this Thursday (Nov. 12th) with the official public release when it becomes available. We will continue to test as needed and make a final determination on compatibility as soon as possible.

Although our testing has not revealed any major problems, we are remaining vigilant about any potential workflow and productivity disruptions. For this reason, we do not recommend updating to Big Sur if you rely on Finale until all testing is complete. 

All previous versions of Finale (v25 and earlier) are not compatible with operating systems beyond macOS 10.14 Mojave. No updates will be issued and these releases will continue to remain in their current state.

Musescore

Official Big Sur status: Not supported
Official M1 status: Not supported

As of November 17, 2020, Musescore’s head of design Martin Keary has provided the following statement to Scoring Notes:

We have tested MuseScore on regular (Intel) devices running a beta of Big Sur and have seen no issues. However, we need to investigate the release version to see if this is still the case. For the moment, it looks like things will run fine but we need more time to confirm 100%.

Regarding the M1 chip (under Rosetta), we have made a change that will allow this to work with MuseScore 3.6, which will be released in December. However, users should be aware that they will not be able to upload scores to MuseScore.com or access the ‘Start Centre’ (due to an issue with Chromium). We will provide more updates about this issue soon.

For anyone using a device that has an M1 chip, we would advise you to upload your scores directly on musescore.com/upload for the time being.

No que diz respeito a outras aplicações, como o Office 365, Adobe Creative Cloud, browsers (Chrome, Firefox, Opera, etc.) e outras recomendamos aos nossos investigadores que façam uma pesquisa antes de actualizarem o SO para o novo macOS ou antes de adquirirem um Mac com os novos chips, tendo em conta que aplicações são essenciais para o seu trabalho. No entanto podemos dizer que a Microsoft já tem uma versão nativa (que não precisa do emulador Rosetta 2) do Office para o novo chip e a Adobe está a preparar uma versão nativa das suas aplicações disponíveis na suite Adobe Creative Cloud para o chip M1 mas que de momento não garante um funcionamento sem problemas para quem adquire um Mac com o novo chip.
