I noticed that my M1 Macs use an Intel process for the screensaver

[johnalan]

Weird place for an intel process... Whenever I run a screensaver on my M1 Mac, I noticed that this spawns an Intel process called: legacyScreenSaver-x86_64.

Anyone else seeing this? I know the entire system (including all the BSD stuff) is universal binary, so it's a little weird this is still intel only.

Anyone else see this? Everything else is Apple Silicon/ARM64

I'm not seeing it. Choose a different screensaver?

Not everything is Universal yet. The CoreAudio driver service is still Intel only as well.(It works though).

thanks, By the way, I fixed that issue with KP on reboot, did you see my post on how?

what do you see when you start the system preferences screensaver pane? What process starts for you?

@Gnattu as systems don't ship with Rosetta installed, I wonder how this works with these legacy intel apps needing it!

When the user launches an app requiring Rosetta, they are prompted to download and install Rosetta. It takes just a few seconds.

Yeah I get ya, I don't know why my Mac is starting Intel screensaver!

I mean I use Rosetta (and have it installed), but it shouldn't launch the intel screensaver instance.

I had a custom old screensaver installed, but removed it. Still no joy.

Is your screensaver choice one that shipped with Big Sur, or is it one that you added? I agree that if it shipped with Bit Sur, it ought to be Universal. Even so, it's not really bad if it launches the Intel code.

Confirmed that an Intel and ARM version both run, it's normal.
