    Apple Previews macOS 11.0 Big Sur - Available Fall 2020

    Apple Silicon I am not happy about Apple moving to their own silicon - but it only makes sense. Intel's year-to-year improvements have been terrible since Skylake - where they moved to a tick-tock-tock-tock-tock cycle and we are now on 14nm+++++ architecture. AMD is eating them alive and Macs...

    Kernel Panic on Catalina fresh install

    @Sasha44 The kernel panic did suggest something to do with a hard drive / ssd. I don't know what patches SSDT-EC.aml applies for you - have you tried to remove it? As I said in the beginning - I am by no means an expert, but for me it just has to be either the physical device itself, or...

    Surface pro 6 Catalina

    You have a weird thing in "KextsToPatch" - where you are patching AppleIntel KabyLake graphics buffer - and you should not need to, as it is natively supported and OK. Also, MacBookPro15,2 is a better fit for the CPU, I believe. Try the attached config.plist and see if it works?

    Surface pro 6 Catalina

    I'm by no means an expert, however, I notice you are declaring your UHD 620 incorrectly. You are using both -disableigfxfirmware and are declaring a PciRoot device. I'm not on a mac at the moment so can't check if it matches mine (I've a same CPU and GPU config) - but one would not play well...

    Kernel Panic on Catalina fresh install

    @Sasha44 I cannot say I know the actual reason, but I would go out to speculate this has something to do with APFS evolving. El Capitan and Sierra were based on a HFS+ file system and High Sierra had an option to cancel the conversion to apfs - not sure about Mojave. I don't think memory...

    Kernel Panic on Catalina fresh install

    @Sasha44 Online research shows that your SSD lacks a DRAM chip, which may very well be the case for your kernel panics. AFAIK, macOS does not support such drives when they are either Journaled or APFS. You will need to replace your SSD. I have found Samsung's SSDs to be the most reliable in...

    Screen refresh rate issue

    Fun fact: When no secondary monitor is connected my internal display runs in a 24bit colour mode, as opposed to the 30bit when the external screen is connected.... do I need to declare different colour space in Clover to set that straight?

    I would imagine that was obtained in safe mode.

    Screen refresh rate issue

    TL;DR Internal screen drops down to 25 or 30Hz when laptop is connected to an external monitor - "Extend Displays" mode. Hi, I don't know if this is a standard issue or not. Admittedly, I rarely attach a third screen to my laptop. I usually reside on Sidecar for a secondary screen. I had...

    Kernel Panic on Catalina fresh install

    @Sasha44 This is a very very peculiar issue, indeed. Can you please confirm the model of your SSD? It could turn out to be an incompatible controller, or one of those SSDs without a DRAM buffer which macOS doesn't like to play with. Also - when you install onto the SSD - I presume you...

    Kernel Panic on Catalina fresh install

    @Sasha44 Sorry for the late response - I was away on a trip for a few days. Just out of curiosity - have you updated your BIOS recently? I am just wandering if your SATA is in AHCI mode, VT-D is disabled and your XHCI handoff is enabled? Those are pretty basic points, and I myself forget...

    Kernel Panic on Catalina fresh install

    @Sasha44 I have a few more suggestions, here goes: * Are you using the latest version of Clover? Update the bootloader just in case. * Change your SMBIOS to iMac17,1 - it is much better suited for your configuration - and in my experience it makes a hell of a difference! Have you done...

    Wifi/BT funky after update

    It has been 20 days and so here is the progress so far: 1. Got a new SSD and did a fresh install of the OS. 2. Chose a different SMBIOS - MacBook Pro 15,2 3. Logged out every device I own and reset it's network settings. 4. Log back in with all devices. The result is the following: I...

    Kernel Panic on Catalina fresh install

    Hi there! I had a quick look through your files. I am by no means an expert, but I noticed a couple of things out of the ordinary: * com.apple.iokit.IOReportFamily - this points to an issue with your hard drive or SSD. I noticed you have a "SATA-Unsupported" kext in your E/C/K/O folder. Did...
