So nobody else either uses Safari, or has memory leak problems with it ?
it happens here on a new MBP.
And on two iMacs.
Everything starts ok, but inevitably, each Safari process (that handles multiple tabs) grows and grows. Within 12 hours of actual non-sleeping time, they are starting to fight with each other for space:
* My Safari is updated, as is OSX.
* I don't have any plug-ins, they are all disabled.
* I've run etrecheck and everything is clean.
This problem has been around for a long time now but has got worse I think this year.
Basically if you let Safari sit on a page, it just eats memory. Slowly and surely, until your whole browser is impossible to use without thrashing. On a laptop it is harder to spot because they tend to get rebooted due to battery going flat or shut down often enough. But on a desktop that just sleeps and is never powered down, within 4 days, it is super obvious.
Everyone else doesn't see this? really? you look at a two week old Safari using Activity Monitor and sort by Memory and each process is a few hundred MBs at most ?
