Hi everyone I have problem with catalina installation on my dell precision 3510. Some people told me I need ssdt?? Is anyone who can help me with this?

I have succesfully install MacOS Catalina in Dell M4800.But when I shutdown or restart the laptop the bios resets the "SWITCHABLE GRAPHICS" option I want to turn this option on because this options disable the Nvidia M1100 and uses Intel HD4600.Nvidia M1100 is not supported in Catalian.PLEASE HELP.

Hello People, Recently I bought a Dell e6430 (i5 3rd Gen) and I am not kinda expert in any other OS except windows. I just want to ask that If i install any version of other OS so which BIOS would be good? I have A17 right now and the latest is A22. I just want to ask that if anybody have tried that BIOS, is it stable so that I can install?

Will updating my E7440's BIOS to the latest version (A20) cause any issues when updating to macOS Sierra?

Can someone explain why we cannot upgrade the Dell E6430 to the latest A18 BIOS? What is preventing us? I have DSDT and SSDT edits in place and have able to get my E4630 to essentially 95% of a real mac, I still cannot restart without Optimus being disabled. Now at A18, from A12, I get horrible screen corruption. It is similar to when the system is booting up, but this is all the time. It seems to affect windows with inactive content - for instance this text box i'm writing this post in is clear, but everything around it is corrupted. Please see attached photo for example:

I have just purchased a Dell latitude D830 for $125 with extras and now need to make a start at trying to get snow leopard working on it. The present bios are A11 is that good for snow leopard?

I though I'd list out the steps that on how I would plan to go about installing Mavericks on this beast. Please and pretty please correct me If I missed out on anything and what I should be aware off. 1. Download Mavericks 10.9 off of mac store. 2. Download and install MyHack 3. Open Disk Utility and create a single partition usb drive .{Mac Os Journaled} Do I select the GUID or the MBR option ?? 4. Open MyHack and follow the EDP documentation. Include Nvidia D830 Bootpack 5. Replace Wifi card of the D830 with DW 1390{Broadcom 4311} 6. Do I go to the BIOS of the computer and enable AHCI ?? 7. Plug in the Myhack flashdrive with usb mouse and keyboard at the ready just in case. 8. Enter -v {verbose mode} and let it run it's course ===================================================================== If Language Selection appears ===================================================================== 9. Fill in the blanks. 10. Install E.D.P 11. Select Config and build from d830 database. Is that how I should go about doing it ?
