This project is dedicated to Lucy, my lovely little indoor tiger. IntelLucy is an open source driver for the Intel X500 family of 10 GBit Ethernet controllers. Key Features of the Driver Supports Intel X520, X540, X550 and 82598 Ethernet adapters. Support for multisegment packets relieving the network stack of unnecessary copy operations when assembling packets for transmission. No-copy receive and transmit. Only small packets are copied on reception because creating a copy is more efficient than allocating a new buffer. TCP segmentation offload with IPv4 and IPv6. Support for TCP/IPv4, UDP/IPv4, TCP/IPv6 and UDP/IPv6 checksum offload. Large Receive Offload: TCP/IPv4 packet streams are identified by the NIC and reassembled to large packets for handover to the network stack eliminating the overhead of packet header processing. Supports jumbo frames up to 9000 bytes (strongly recommended for 10 GBit/s operation). Designed to work with High Sierra and above. Supports Wake on LAN tagging. Supports hardware VLAN (untested). Support for Energy Efficient Ethernet (EEE) is planned for future releaes. No need for hardware modifications anymore (used to be required for SmalltreeIntel8259x.kext). Compatible with AppleVTD but also works fine with AppleVTD disabled. The driver is published under GPLv2. Current Status IntelLucy has been successfully tested with Catalina, Monterey, Ventura and Sonoma and is ready for use in production systems starting with version 1.0.0. Thanks to jumbo frame support, performance is much better than com.apple.DriverKit-AppleEthernetIXGBE. VLAN support has been fixed and tested in version 1.0.0 and is fully working now. I can't test Wake on LAN because I don't have an adapter with WoL support. Tested Configurations X520-DA1 with the following media: Passive DAC cable: working 10GBase-SR SFP+ modules: working 1000Base-T SFP modules: working X540-TA1: working (see note below). X540-TA2: both ports working (see note below). Known Issues Manual media selection doesn't work. The link is always established with the highest data rate both link partners support, i.e. 10 Gbit/s if both endpoints support it, 1 Gbit/s if the link partner is a Gigabit device, etc. As DAC cables and fibre optics usually are fixed-speed devices, only RJ-45 ports are affected by this limitation. Try to avoid media with flow control enabled as it might cause repeated connection drops due to transmitter hangs and serious performance issues. For WoL to work you need 4 things: An adapter which supports WoL (only a few X520 adapters support WoL). A mainboard which supports WoL from an add-in card. WoL must be enabled in the UEFI setup. Proper ACPI tables for MacOS to support wakeup. Installation Use OpenCore to inject the driver: Getting the driver A prebuilt binary is available in the download section: https://www.insanelymac.com/forum/files/file/1061-intellucy/ Source code can be found on GitHub: https://github.com/Mieze/IntelLucy Changelog Version 1.0.3 (2024-04-17): Disabled ASPM for the X520 adapters as it is broken and may case erratic behaviour. Enabled ASPM on X540 and X550 provided they report ASPM compliance. Fixed a link status reporting issue for RJ-45 ports (X540 and X550). Removed support for 10 Mbit/s data rate (unsupported on X520 and X540). Resolved a conflict between adaptive interrupt throttling and Receive See Coalescing. Version 1.0.0 (2024-04-07): Fixed relaxed ordering of PCIe transactions. Fixed and tested VLAN support. Version 1.0.0d9 (2024-03-27): Improved transmit performance. Version 1.0.0d6 (2024-03-20): Added support for Intel 82598. Version 1.0.0d5 (2024-03-19): First public release. IntelLucy configuration Parameters explained The Info.plist file contains a section with configuration parameters ("Driver Parameters") which will be explained in the following section: enableTSO4: Enables support for TCP segmentation Offload with IPv4. Using TSO4 the NIC receives large TCP/IPv4 packets from the network stack to be split up into smaller packets to be transmitted of the network. TSO4 is a major performance feature and required to achieve TCP transmission rates near wire speed. enableTSO6: Enables support for TCP segmentation Offload with IPv6. enableWakeOnAddr: Currently unused. enableASPM: Enables Active State Power Management (ASPM) on X540 and X550. rxBufferSize4k: Use 4KB receive data buffers instead of 2KB buffers. rxCoalescing: Enabled the use of Receive Side Coalescing which is the receive side counterpart of TSO4. The NIC identifies TCP/IPv4 packets belonging to a TCP stream, coalesces them into large packets (up to 64KB) and hands them over to the network stack reducing header processing overhead. Enabling rxCoalescing enforces the use of 4KB receive buffers. µsPollTime10G: Under heavy load receive and transmit interrupts are disabled and the NIC is polled periodically for packets waiting to be processed. This feature greatly reduces CPU load while operating at full speed. The polling period is given in µs and used when 10G Bit/s link speed is established. µsPollTime2G: Same as µsPollTime10G but for link speed 2.5 Bit/s (X550 only). µsPollTime5G: Same as µsPollTime10G but for link speed 5 Bit/s (X550 only) µsRxItrTime: Interrupt throttling is important to achieve high data rates while keeping CPU load low. This parameter determines the minimum timespan between two receiver interrupts in µs. Values below 10 enable adaptive throttling. µsTxItrTime: Same as µsRxItrTime but for the receiver interrupt.

No kext. Need to add another one

Hi Mates, I got gigabyte Z790 Elite X wifi7 but, wifi7 is mediaTek not Intel.... is there any kext for it or i have to replace it with intel BE200? Thank you

Built Citra, it is a better emulator.

Doesn't Work, Reboots Edit: Wonder What Has Changed in 14.4? Thanks

I am gradually approching my goal of creating a functional AMD Kernel for High Sierra (K8/K10/K15). Here is a picture from the last boot with my new amd kernel. In a previous attemt, the system stopped at kernel Extensions in backtrace with various USB Kext drivers being implicated. I am currently working on resolving these driver issues, and in the next step, I will try to generate the prelinkedkernel, hoping to successfully boot into the desktop thereafter.

I was using it, and it's awesome. 😁 There's no problem with dual-boot, it's just OC even better with this feature (not inject OC properties in another system). About upgrade, I always do the test with a USB stick, if it boots then I put the newest files at my EFI. If not, I can do some researches and see what's happening, and doing this way I can keep my current OC as it was. 😉

👉 Rules Our goal is ensure that the forum remains a helpful & friendly place to learn about how to run Mac OS X on non-Apple hardware, and of course other general banter. We want you to be able to discuss anything and everything here, and to do so we ask that you check out these guidelines for forum use. Do not upload anywhere else files when developers specifically ask not to. We take this matter very seriously, as developers are the very heart of our community. No Flaming. This includes racism, threatening, personal attacks, victimization or hateful content. Retaliation will not be tolerated either; if a member has broken a rule, please use the report feature on the forum and the staff will deal with the situation appropriately. No posting of direct or indirect links to warez or pirated pieces of software, this includes cracks, serials and torrents. Do not publicly argue the decision of a moderator. If you disagree with a moderator take it up with them in private via PM. Only one (1) login is allowed per member. Duplicate accounts will be banned or deleted. Bumping of posts is not permitted. Other than being less annoying it also keeps the posts more informative. Meaningless and useless posts may be removed at Moderator's discretion. Only post your post once (1). This keeps the forum cleaner and makes it easier to find what you are looking for. No advertising or business offers of any kind. No posting of copyrighted material. This includes copying and pasting news articles from news websites. Attached materials must come with clear descriptions of what they are and what they do, linking to this information elsewhere is not sufficient. Materials derived from Open Source must include source code, as well as an explanation of what has been done to it. Discussion of P2P, torrent sites, or similar download sites of any kind will not be tolerated. We do not want to know your illegal downloading habits. Do not post spyware or any other malware. This includes linking to other sites which may contain it. Posting just to promote another site, product, or service (spamming) is not allowed. This site is not here for you to promote your own or anyone else's material. Discussion of commercial spin-offs of the OSx86 scene is allowed if it’s to understand their existence, but no discussion of how to use them, nor any support for these commercial spin-offs are allowed as they are not in the spirit of the OSx86 scene. Example of commercial spin-off: tonymacx86. Why InsanelyMac does not support tonymacx86 VERY IMPORTANT: PLEASE READ! (ABOUT TONYMACX86 AND iATKOS M / Y / EC / SR) 👉 Posting Guidelines If you have a question please do your best to use the search feature and search the forum before creating a new topic. Post in the correct forum and read the forum description. This will make sure that your post will not be removed. Pick an appropriate title and tags (if any) for your post. A good title makes it easier to find what you are looking for. Using informative tags allows for improved searching of related topics. All posts must be clearly written and easy to read. For example, if you have long blocks of text, use the Code option, etc. Limit "empty lines" as much as possible, use punctuation where you can and be concise. Posts may be edited for this reasons by InsanelyMac staff at their discretion. Please remember that you are in a public forum, a bit of courtesy is always welcome. It's always nice to start by saying "Hi" or "Hello" before asking a question or seeking help. Also a "thank you" would be appreciated, especially if the help you get is effective. Your topic does not deserve any more attention than others seeking help hence topic titles must reflect their content, and topic titles containing things like: 'please help' 'look here' 'cash reward' 'urgent' or other inaccurate descriptions will be removed. This includes all-caps titles. Give your hardware specs when necessary (asking for support) and any other time where it may be beneficial to have them listed. Watch this video to guide you how to do that: [Video] How to add a signature. 👉 Signatures, Avatars and Nicks Keep your signature/avatar clean and tidy - should you receive a PM from the staff regarding your signature/avatar, please make the requested alterations or it may be removed/shortened appropriately. To keep pages loading fast for everyone, we request that your signatures and avatars contain no animations or high-definition graphics of any kind. Signatures should be no more than 6 lines of text using a regular font. If you can't fit all of your system specs in that you'd like, why not create a small graphic to contain the information? They should also contain no referral or affiliate program graphics. Avatars should be in "good taste," a qualification that is broad enough to let us determine what is and isn't. Goth-devil-child-wild-eyed-in-the-violent-blackness probably qualifies as being in bad taste. Nothing offensive, pornographic, or vulgar. Nicknames must be readable by the system (without question marks). This will ensure that your nickname can be searched, and that other users can contact you. They should also not contain staff member groups (administrator, moderator, developer, etc.) to prevent confusion. Nicknames should also show respect to the community, thus nothing containing offensive language. Email addresses must be real. Accounts not in line with the last two rules will be edited or deleted without warning. 👉 Policing Do not publicly discuss the decision of a moderator. If there is any issue with a decision of a staff member PM them or contact an admin. Moderators have the ability to suspend or impose posting restrictions upon accounts based on the user's history. Records are kept to keep track of user's behavior and point out repeat offenders. Attempts to circumvent posting restrictions will lead to your account being banned, and any other accounts affiliated with your account being banned also. These rules cover a broad spectrum and are set up to preserve a free and open (and fun) place for discussion. They, in conjunction with common sense and good judgment, should steer you in the right direction. We're all human and we know that people make mistakes... but that's also not an excuse. More rules are subject to appear on this board as we see fit, so please check back from time to time for your own benefit. Thanks for joining our community and helping make it the best it can be. In case the rules localizations should differ, the English rules are the standard.
