TUTTO bene👍

Hello, during copying data to a new system I noticed some issues. I'm using on all drives a similar partitioning system so it is possible to clone partitions using Disk Utility instead of copying the data filewise. I own three Seagate Barracuda ST5000LM. These are 15 mm high 2,5" drives with 5 TB capacity. So the data desity is very high. Still all three are in last place, even when connected to SATA 3. Even a thirteen year old WD Blue WD10JPVX - also 2,5" - had better scores. Unexpectedly for me was the winner of my tests, a Samsung 2 TB mSATA drive. These are to find in the Samsung T3 or T5 external SSD's. From the looks it seems to be a Samsung 850. I have not expected that a 9 year old mSATA drive ripped out of an USB-C device is better than my other SSD's. The weirdness increases because this drive has some faulty blocks which are not shown in the SMART information. I had to leave some areas unpartitioned to avoid these problematic blocks. Had somebody else noticed slow hard drive speeds on the Z77 chipset? Greets, naquaada.

OK

Salve a tutti come da titolo cerco una scheda video amd x fare hack ad un amico, non cerco niente di speciale ma solo qualcosa che funzioni.

avevo dimenticato di postare lo screen 🙂

welcome here No it is not possible by now (also in my new Hero x870e motherboard it is only possible to charge a phone/ipad)

I have read at various online sites, that the iGPU is not supported for macOS. Was hoping if it was possible to use the USB4 for DP-AltMode connections. This is the unsupported Asmedia port?

Phew. Finally finished the new version of the Q77M-DS2H. It now has a dellidded i7 3770S with fresh Arctic MX-6. I use a Scythe Ninja Mini with two 92mm CPU fans and two 120 mm case fans. In normal use and with closed case the cpu is about 40°C, but the cooler fans are actually limited to 5V to be quieter. A stresstest was creating a disk image using bzip2 compression. Disk Utility uses 780% CPU time, the rest ist used by the system, so this is a really good method to max out the CPU. 55°C was the highest temperature. I'm using a Sharkoon Quickport Internal removeable drive bay for a 5 1/4" slot. It has one 2,5" drive and one 3,5" drive, as well as two USB 3.0 ports. I also added a DVD drive, but I know I have somewhere a BluRay drive. The 4 TB HD I prepared didn't fit in the case, so it got a Seagate 5 TB 2,5" HD. It is 15 mm high and rather fast for its size. I still have one PCI port and one PCI-E x 16 port (4x speed) free. That's how I like it. Everything squeezed into a compact, silent case and still expandable.

in Download you will find many useful things, also take a look at useful links, you will find guides and much more, in short this forum is very well made and by people crazier than insanelymac 🤣

if you go up to download here you will also find very useful things, for example this https://macos86.it/files/file/91-powertool/ 😜

macOS Sonoma 14.7.6 (23H616 ) 👍 ci ha messo un po ma alla fine è riuscito ad installarsi- alla prossima

Wow, you are replying quickly 👍 After I used the EFI partition, it was a bit annyoing to mount it every time. So I wrote three AppleScript files which can mount the EFI partition on drive 0, 1 or 2. I just need to add them in the startup objects. I also wrote a tool to kill the disk cache. This can get very large, I had values over 10 GB. Using the terminal command 'sudo purge' this cache can be cleared and frees lots of memory. I wrote an AppleScript file for this. Can you use these tools?

I use this OCAT, very accurate, you can mount EFI, and update Kext and Driver and you can update the OC bootloader to the latest version, follow the guide (in IT) easy to use. Or there is OpeCore Configurator not always stable but does its job https://mackie100projects.altervista.org/download-opencore-configurator/

This really sounds good. But I'm still not finished with the hard disk. There is an unexpected problem. I'm using a 7200 rpm WD Black, and it gets very hot in my Sharkoon Quickport, I had more than 53°C. So after every cloned partition I have to shut down the computer, take the HD out and let it cool down for a long time. This makes the cloning process even longer. Can you give me links to an actual OpenCore installer and Configurator? As I tinkered last year with the Asus Prime, and there were two incompatible configuration files for OpenCore, is this problem solved? I can't check the contents of this installation, because I used the old Apple NVME SSD for experimenting. It is in an adapter which is 110 mm long, so I can't use it in my external case. But maybe there are some files on the SATA M.2 SSD.

I forced the loading of the 4000controller.kext only on monterey with a max and min kernel and put in devices proprerties the framebuffer suitable for OlandXT you could also try on other systems, it will not force the patch to load, or you can use Clover and Opencore so you can boot the systems you want separately

yes this is your modified config, I repeat your video card is based on another framebuffer and the r7.250 does not have the same as the r9 what you are now trying to make believe

Sounds good. Is this plist based on my EFI folder's configuration? But this won't fix hardware acceleration in Mavericks and Mojave I guess. My 7000/X4000 kexts are somewhat modified, but I don't know anymore what I changed. I'm also having AMDVerde.kext and ATY_init.kext in System/Library/Extensions. My HD 7870 has device ID 6818 and uses Pitcairn XT. It is using Chutoro as Framebuffer. On the GPRO 4200 and 6200 Dashimaki and Futomaki are working.

Ahh there! Yes, it all makes sense then: seeing "Pitcairn" as the framebuffer is a sure sign that macOS is not using AMDRadeonX4000.kext, but something else — probably a broken fallback or a bad match from AMDRadeonX5000Controller. Monterey sees your device-id 0x682B, but it doesn't load the right kext (X4000) because of the policy. Instead it tries to handle it with a wrong framebuffer, like Pitcairn, which is not compatible. Result: no acceleration, black screens, or only VESA mode. config.plist2 we force the kext 7000 and 4000controller and patch them try config 2.plist.zip

@naquaada macOS Monterey disables GCN 1.0 support via policy, even if the ID is present. Some IDs (like 0x682B) remain in the plist for historical reasons or internal backwards compatibility, but: AMDRadeonX4000.kext drivers are not loaded. Even if the kext is present, matching fails at runtime. This also applies to 7000Controller.kext, which does not contain Oland-compatible framebuffers, so even if it "sees" the ID, it is of no use. Great point! Yes, it's true: the ID 0x682B (i.e. your RX 250) is present in both: AMDRadeonX4000.kext ➜ legacy GCN 1.0 drivers (Oland, Cape Verde) AMDRadeonX5000.kext / X7000Controller.kext - used for newer models, but sometimes with leftover support - But be careful: being listed in kexts does not mean they are actually loaded! Check with gpuid if your card has Uefi support or if it needs to be flashed, try my config.plist, I put a more compatible framebuffer in the devices proprierties "Futomaki", but you can also try Hamachi, remove the no_comact_check from the boot arg and still keep your config working configOlandXT.plist.zip

I've changed it. Manually, because OpenCore configuratiorator doesn't work on Mavericks. But why is a new OpenCore configuration neccessary? The one on my Monterey USB drive is working, even with MacModel 13,2 like an Ivy Bridge system should have. I only have no graphics output. What is neccessary to get the graphics card working? The GPRO 4200/6200 are based on the Radeon R7 250X. I often read that it requires radpg=15. I guess this is a WhateverGreen option. On Monterey the AMD7000Controller.kext and AMDRadeonX4000.kext both are containing the device ID of my graphics card. In the attachment is the EFI folder of the Monterey USB drive. EFI_naquaada.zip

Open config.plist with OpenCore Configurator or ProperTree and set: Misc -> Security -> Vault = Optional
