Issue: Cursor (agent mode) is eating up all my memory Mac pro M3 Max 128 GB RAM. Looks like a memory leak somewhere in cursor’s own code.
Way to repro: Use cursor in agent mode with the latest (0.49.x and the version previous to that as well)
Impact: Cursor freezes and so does my mac becomes slow and unresponsive
OS: Sequoia 15.3.2 (24D81)

Cursor team, are you taking notice of this actual major bug ?

I experienced something similar on Windows v48, but when system started to slow down it crashed and after new start it didn’t do it again so i didn’t look into it more.

Actually, restarts didn’t do it for me. But disabling extensions did
