but the brightness is always full after booting. Do you know how I could retain the brightness value between restarts or set a preset value?

maybe an NVRAM problem?

You can download SSDT-PNLF update from Hackintool - when you download WhateverGreen.kext

Is there a better way to do it?

Thanks again
Yeah - to take the DVD drive out of the laptop ... in my case, that's the only way to make sleep/wake work properly.
Because optical drive leading to panic reboot:
"IOSCSIPeripheralDeviceType05::setPowerState(0xffffff8091f2a420 : 0xffffff7f8679918a, 1 -> 4) timed out after 100829.

look

Hi, hoping someone can steer me to the guide for upgrading my Lenovo Z50-70 to Catalina from Mojave. I have not been able to locate the guide either by using the search item or my browsing all the postings. Thanks for you help.

Done. Keep calm and wait, wait, wait
Any guide or special steps for update to BigSur?
Can we do with fresh install or should we update from Catalina to BigSur?

I can try that
but didn't get OC meaning. (Silly me).
I'm running on 10.15.3 (not able to update to 10.15.7, that's why I want to directly Big Sur)
