Issue with Claude Code using Claude Desktop on MacOS Monterey

[u/zuiquan6174]

Hello,

A few hours ago I was using Claude Code using the Claude Desktop interface.
And suddenly the window disappeared, but the app was still running.
I closed it, restarted it, and since then it complains that I need to upgrade my OS...

I do not want to upgrade. So, is it possible to get an older version of the app somewhere and to prevent the update ?

Here is the detailed error:

Claude Code process exited with code 134. stderr: dyld[96412]: Symbol not found: (_DNSServiceGetAddrInfoEx)
Referenced from: '<home>/Library/Application Support/Claude/claude-code/2.1.255/claude.app/Contents/MacOS/claude'

It seems the last update (Claude 1.40609.1 (69aac0) 2026-08-30T23:12:49.000Z) broke it.
How can I get the previous version ?
How to download that previous version ?
Alternatively, I have the months old install I used, but can I force update up to the previous version, but not the last ?
And then, how to prevent any update ?

Do not know if this website is reliable, but it lists the versions and we can download older versions:

https://claude.en.uptodown.com/mac/versions

So, I downloaded this one:

https://claude.en.uptodown.com/mac/download/1207405380

I renamed the recent Claude.app in Applications.
Then, I installed the downloaded version.
I had to freeze (right-click on the Claude.app, get info in the menu, and check the lock checkbox)
otherwise the latest version come back instantly.

Alternatively, this should do:
sudo chflags uchg /Applications/Claude.app

And now, it works again.

desktop pulled a binary that needs a newer dyld symbol. monterey's done for that build.

use the claude cli in terminal, or roll desktop back and block auto-update.

Which version were you able to roll back and can you please share the commands?
