I've just installed Evernote on a new MacBook Pro and was pretty disappointed to learn that it still needed to use Rosetta. Then I discovered the move to Electron, which also explains why my Applescripts stopped working. I'm behind the times, it seems.
I haven't experienced any particular problems with speed with Evernote 10; maybe I'm just lucky.
That said, the performance difference between Evernote 10 and Apple's own Notes is vast. I'm sure that's partly because I have 10k+ notes in Evernote and only a few hundred in Notes, but the difference is so stark that even when Evernote is 'fast' it feels extremely slow by comparison to Notes. Interestingly, I see similar differences on an iPad Pro.
Doubtless the decision to move to Electron was taken long before Apple announced their silicon transition. I'm sure it looked like a logical choice - develop once, deploy everywhere. Great for developers, lousy for users.
Maybe things will improve when Evernote migrates to Electron 11 with support for Apple M1. Do we know if that's happening?
In the meantime, I have two workarounds for my AppleScript-related issues:
Like everyone else has pointed out, Evernote Legacy still works. I've installed this specifically to run AppleScript, which I only use once or twice a week to create a few dozen templated notes. Then I switch back to Evernote 10, and
Notes. I re-wrote my scripts to target Notes instead of Evernote. This might not work for everyone, and honestly I don't like having notes in two apps, but the speed of Notes has to be seen to be believed.
My wishlist is short; I want AppleScript support restored to Evernote, and I want an M1-native app that prioritises user performance. Big asks, I know, and maybe the Mac user base is never going to be big enough to justify the effort, but I'll be keeping my eyes open for an Evernote replacement until this gets fixed.
