Installing Rosetta 2 on an M1 iMac

Hi,

I recently reinstalled macOS (Big Sur, latest version) on my iMac as a result of a few issues I was experiencing. After reinstalling my apps, I noticed Intel-based apps in particular were crashing upon open, and the pop-up as shown in this article https://support.apple.com/kb/HT211861 hasn’t appeared once since reinstalling macOS.

Theres also no sign of “Open using Rosetta” in Finder for any of the Intel-based apps I have installed. I can’t seem to find any way to install Rosetta or open Intel-based apps.

The error message that appears when the apps crash also seem to indicate Rosetta is the issue.

Any ideas for a solution, besides reinstalling macOS again?

iMac 24″, macOS 11.5

I was able to find a great article that allowed me to install Rosetta 2 and use these Intel-based apps as normal with a quick terminal command. https://derflounder.wordpress.com/2020/11/17/installing-rosetta-2-on-apple-silicon-macs/

I will hazard a guess here. We are told by Apple that we do not need to install Rosetta unless and until we get a message that it is needed. Apparently, it will then be installed automatically for us. I saw somewhere recently (Sorry, I don't remember where it was) how some apps are shown as Rosetta compliant or not. Those which were compliant would open in either computer, M1 or Intel. I am going to guess that your app's provider thinks they are Rosetta compliant, but they have somehow screwed up. I would check their web site and see what they say. You may want to download a more recent version if one is available. I hope that works for you.

Rosetta 2 installs automatically when it is needed. That you had to research and install it yourself indicates a system that is not stable at all. Be ready for more glitches and problems.

When you launch an Intel based app it should NOT crash. You should be be offered the option to install Rosetta 2.

The interesting thing is it’s happened for all Intel-based apps, not just some. And before I reinstalled macOS initially, all of these apps worked perfectly fine with Rosetta. It’s a strange issue..
