You type it as a boot argument/option when you go to Clover Options menu at Clover boot screen ! Above picture is not a problem at all, it's the normal early info displayed in verbose mode since 10.15.4.

It's been said to cause issues for some time but that's clearly totally unrelated and irrelevant to your Clover Boot Manager matter. No link whatsoever.

Patched DSDT is in ACPI/patched folder of the packs I had posted (now moved away to avoid issues). If you've not done so, remove it as it would cause your computer to KP. Again, forget about BIOS version, it's irrelevant.

Erm... just for the sake of clarity, you didn't just copy the zipped Clover pack to your EFI/Clover folder did you? Instead, you unzipped it and copied/pasted the unzipped contents then removed the patched DSDT, right? If you're installing latest version of Catalina, i.e. 10.15.5, you may want to boot with -disablegfxfirmware boot arg. I had found it to be required when updating to 10.15.4 as stated here. Don't use any Clover version older than r5117. As suggested by Jake Lo, there was no need to downgrade BIOS to v1.13.1 at all, the 7490 runs macOS just fine with v1.14.0.

4) isn't it fully described in my guide?

All is fine then. Your update went to full completion and removed all temp data/folders.

'means exactly what I said: /System/Volumes/Data directory had be manually deleted.

Wasn't HFSPlus.efi module removed from Slice's recent versions? You'd get it from older versions like r5103 off Did's Github repo.

What do you mean "tried them right now and nothing [...]"? If all you did was copy your dumped tables in the ACPI/patched folder, that's totally useless. In case you ignored this, all bootloaders do load tables from BIOS as they are... ACPI/patched folder is used for patched tables as its name implies...

Of course he did. No Atheros card is natively supported since Mojave, let alone AR9565 models.

Plenty of tools do dump your ACPI tables from Windows. For instance, Aida64. You can Google for that.

As per our posted rules, please refrain from double/triple/multiple posting on our forum for the exact same matter. For the rest, have a look at the (old) threads related to supporting Atheros-based Bluetooth modules under OS X/macOS by EmlyDinesh & BlackDragon. However, note that both have left the scene for a while now and don't expect much of an answer if you have questions.

Not much really. OC is not mature enough to my liking and definitely not for newbies. As for the faster boot time, I'm not sure that really is true and/or noticeable.

Why don't you stick to Clover then? Any particular reason or need to switch to OC?

Moved to its own thread to avoid the complete off-topic in an M4800 thread...

No, what you saw is perfectly normal. You've just got some significant catch-up to do re: macOS Catalina.

Guys, please refrain from using quotes to post replies. Forum provides a Reply box at bottom of pages.

-> moved from Feedback section (where it had nothing to do) to appropriate Dell Latitude E7xxx support section. Please make every effort to post in the right place.

As long as the actual data occupied less than the target disk size, you should be Ok with any cloning or backup utility/program. The simplest manner of all is to make a dmg image of your HDD partition through Disk Utility (from, say, your booted USB installer), then restore that image onto the target SSD.

The same way you initially did.

What's the reference/part number of the card? Kepler-based GT710 are supported OOB up to current Catalina. Same applies to other GK208-based GT720/GT730. If it's a Fermi model, it's of no use. Kepler cards Kepler 2.0 cards Kepler 700 Series (desktop) Kepler 2.0 700 Series (desktop)

Intel i5-3570 is indeed fitted with HD2500 iGPU. That's unsupported as posted in our unsupported GPUs thread. There is no patch or workaround whatsoever. You'd have to replace your current CPU by a model with HD4000 iGPU or install a supported PCIe graphics card.

In the absence of any information such as laptop specs, stuff you used to build your installer (bootloader, bootpack, etc.), it's going to be impossible to assist you. All I can suggest is that you consult the existing threads related to Precision 3510 posted in this very section.

According to your IOReg, SD card reader is Realtek RTS525a. Please refer to our recent News article on our Home page and/or our dedicated recent thread in the SD card reader forum section. No guarantee that the recently developed kext will kick your card reader to life but it should. With regards to USB, there are a number of mistakes with your setup: your Skylake laptop has no USB2.0 hub (only USB3), i.e. no EHCx controllers. As such: delete those EHCx to EH0x renaming you've configured in your Clover config file delete those SSDT-EH0x tables you're injecting through ACPI/patched you're not using USBInjectAll kext + SSDT-UIAC table or USBPorts kext download Hackintool app and generate your USBPorts kext + SSDT-UIAC.aml table use either USBInjectall + SSDT-UIAC.aml together or USBPorts kext on its own Once you've done that, your USB ports should work properly. With regards to LCD screen brightness, please post an IOReg before and after sleep/wake so that we compare iGPU data.
