Cleaning Intel translations
On my M1 MacBook Air, Rosetta 2 keeps a lot of translated Intel apps even when their originals have been removed. How can I clean those up and recover the space?
To start off, when you install an app that isn’t universal but only contains Intel code, your M1 Mac detects that and passes it to be translated into ARM code so Rosetta 2 can then run that app. This is actually performed by a background service named oahd, which also stores the translated code in an .aot file inside a folder with a long and incomprehensible name in the hidden folder /var/db/oah.
Rosetta’s aim is to perform this ahead of time, which gives rise to the abbreviation AOT and the extension. This aims to have the code ready to run before you use that app, and so you then don’t have to wait when you want to use that app.
oahd then manages those translated files, depending on their use and pressure on free space on that volume. As there’s no command you can use to remove a set of .aot files, and that folder is locked down and protected by System Integrity Protection, there’s no easy way to thin the files in there, so you have to leave it to oahd to handle them. The only easy way to empty that folder would be to wipe your Data volume using Monterey’s new Erase All Contents and Settings command, and set it up afresh, which is a great deal of effort to save what is likely only a small amount of storage space.
Create a new list
Before you can assign tasks, you need to create a shared list from which to assign them. In Reminders, tap Add List. Choose iCloud. Give the list a name, and, if you like, choose a color for it and icon to represent it.
Share the list
Tap the list in the main Reminders screen. Tap the “…” at the top right. Choose Share List. Select a method by which to share the list. Add the people you want to share with as recipients, and a message. Tap Send.
