Anyone get sidecar working smoothly? I can connect, but its pixelated. Not very good for retouching
thanks

SideCar works very nicely with my 11-inch iPad Pro. No pixelation and quite snappy performance. I have the Fenvi FV-T919 for WiFi/BT.

First of all, it's great that you have a full bootable backup!

Upgrading Clover on the main disk should be straightforward, but we should upgrade to the latest version, which is 5100. If you decide to try this again (I'm not saying you should do it now), here are some guidelines:

• Ensure that your backup disk is updated and ready for disaster recovery.
• Download the Clover package file (.pkg) from here.
• Run the installer file and select these buttons and options:

  View attachment 441187
• The installer will mount the EFI partition and it will leave that partition mounted when it finishes.
• Using Finder, examine the files in the updated CLOVER folder.
  • You will see a new CLOVER/drivers/UEFIfolder
    • Delete all files inside this folder, but not the folder itself.
  • You will see the old CLOVER/drivers64UEFI folder as well
    • Delete this folder and its contents.
• Download Catalina Fresh Install.zip from the Catalina Mini-Guide.
  • Inside the ZIP you'll find a folder called Copy-to-drivers-UEFI.
  • Copy all of these files to CLOVER/drivers/UEFI.
• Now add the Boot Argument agdpmod=pikera to your config.plist. This can be done using Clover Configurator:
  View attachment 441190
• Save the file and quit Clover Configurator.
• Reboot and check that Mojave still boots up.
• Use the system for a few hours or a day to ensure that it's stable and will boot up repeatedly.
• Then attempt the Catalina in-place upgrade once again.

@CaseySJ you are a life saver - this is exactly the guide I was looking for. I will apply it (and the Kext upgrades) as soon as I feel ready to try again. And thanks also for all your helpful backup advice, this is the first time I used it in a real-life situation.

Thanks,
I've got the Fenvi 1200, maybe I should change it.

@totototo see attached zip (serial, MLB and UUID redacted)
@trouble74 sleep works great other improvements include:

• faster booting
• native nvram working on Z390 (if you use DSDT)
• Netflix (but this is because OC forced me to disable iGPU and I switched to SMBIOS iMacPro1,1 with AMD GPU, see here)
• future proof, as AFAIK everyone believes OC will supersede Clover as the go-to Hackintosh boot loader (this was my most important drive)
• more native feel (ie if you hold OPT during boot you can choose a different booting partition, just like a real Mac would)

I haven't received my Z390 Designare board yet, but I was wondering if you were able to get your Vega 64 into slot 1.

There are 2 more steps we need to do! I've added them to the previous post.

It may not be necessary to change the card. Instead, it might be worth purchasing an outboard antenna and locating it closer to the desktop. Here's one such product:

• native nvram working on Z390 (if you use DSDT)

I am no expert in ACPI, but with lots of help from rehabman in the past, I am able to do some rudimentary DSDT cleanup and patching.
however, that is an intimidating list of patches you posted earlier, and some of the items on the list are cryptic. hopefully over time, someone will figure out the minimal patching needed for nvram to work with OC, and then convert that to a/some hot patch(es).

Re: Fenvi 1200 issue:

Could you use an SMA male to SMA female RF extender cable and keep the antenna that comes with the Designare?

I might want to park the new machine in the basement and run all the cables through the floor of the studio like I did with the G4 and the G5.

Thanks, I was literally right next to the computer antenna, funny even with the iPad Pro connected via usb it was pixelated and choppy.
