Jazzoo Posted July 27, 2021 Share Posted July 27, 2021 I just updated my 7490 to test the latest Big Sur 11.5.1. Everything seems to work properly except I have screen glitches after boot screen. It happens everytime and the only fix I found is to put the laptop to sleep, after wake up glitches are gone. It also happened on 11.5. Back to 11.4 everything was fine. Strange... any help is appreciated. Maybe some graphics issue underneath. I used @Hervé's files from his guide. Here's my ioreg + oc. Jazzoo’s MacBook Pro.zip EFI.zip Here's the video I recorded - https://drive.google.com/file/d/1tF4ZzK2j0bi6jDZK822odcQ_HTf7OYE9/view?usp=sharing Link to comment Share on other sites More sharing options...
Baio77 Posted July 27, 2021 Share Posted July 27, 2021 I analyzed Ioreg + EFI and I notice duplicate SSDT, things have changed over time, it needs to clean \ update the EFI, at least in my opinion Test This https://drive.google.com/file/d/10UhZHgUeyTpZ8s0u5KQuGuSioaY14IAK/view?usp=sharing ioreg Link to comment Share on other sites More sharing options...
Jazzoo Posted July 27, 2021 Share Posted July 27, 2021 Thanks for the tip Baio77! Can I delete one of the SSDT entries in order to clean EFI or it's not working that way ? PS - I found that changing the resolution to 1600x900 also fix the glitches immediately. Link to comment Share on other sites More sharing options...

Baio77 Posted July 27, 2021 Share Posted July 27, 2021 in USB test this https://drive.google.com/file/d/10UhZHgUeyTpZ8s0u5KQuGuSioaY14IAK/view I apologize for this I write, but the purpose is to give you a very good and functional EFI, in your config I see this All those rename are NOT needed, for sure rename _DSM to XDSM is to be avoided on PCs equipped with I2C such as rename ECDV to EC and other rename EDIT SSDT PMCR only use on mobo 300+ series, older HW has PPMC in ACPI which is the same, so another duplicate Link to comment Share on other sites More sharing options...
Jazzoo Posted July 27, 2021 Share Posted July 27, 2021 Thanks for your time Baio77! I just tested the EFI and the glitches still appear I am pretty new in troubleshooting so may be I am missing lot's of things there. Link to comment Share on other sites More sharing options...
Baio77 Posted July 27, 2021 Share Posted July 27, 2021 Ioreg my EFI I need to do tests, let's start to fine-tune the basic EFI, you'll see that every problem is solved I am a self-taught user, I need time and tests to be able to solve the various problems but everything works out, it takes patience and time 1 Link to comment Share on other sites More sharing options...
