macOS no longer allows changing wifi mac address

If you do so don't get a T490 or if you do don't get an NVidia card. It'll destroy your battery life. The (Lenovo and others) forums have threads on these issue. For me idle time dropped from 11 to 3h.As someone else mentioned as well don't get the "best" WWAN Modem (850 something I believe ) as there are _no_ Linux drivers.

In other news: anyone wants to buy a lightly used lenovo T490?

It wont destroy your battery life. I have a t480s with the nvidia card. You need to turn the card off when booting linux and just use the cpu for display. Research a bit about bumblebee and bbswitch.

Wait, how is "it won't destroy your battery life" somehow supported by "you need to turn off the card when booting linux". It sounds like you're saying it will destroy the battery life if it's not turned off. Did I misread that?

Sorry, I should have been more clear. Do you have a reason to use the graphics card on battery in Linux? Most people don't, so turning it off makes sense. You didn't misread it.

The problem is that on the T490 you can't turn it off. It never enters power saving states on Linux and there's no UEFI option to disable it.

There's plenty of threads on the Lenovo forums about this.
