gemino Posted May 9, 2022 Share Posted May 9, 2022 Hi, I am getting a bit desperate trying to resolve sleep issues in 7490 in Monterey/Big Sur. I would be grateful for help or pointing in the right direction. Thanks! MY GOAL: * either fix sleep issues * or mitigate these issues by disabling sleep completely * understand why WIFI is so slow? Currently only getting 250Mb on DW1560 with all kexts and patches. PROBLEMS: Due to COVID, I worked for 2+ years from home. I built myself a desktop Hackintosh workstation as that was really the only viable option long-term, without shelling $3000+ Now I am expected to work from the office twice a week. I need a Hackintosh laptop to maintain my workflow. I bought this 7490 two weeks ago with the sole purpose of converting it to a budget MacBookPro. Everything that is important works pretty much out-of-the-box. The only missing piece is: * WIFI - got it working with DW1560 but slow. Can't make Intel 8265NGW working again at all. And I had much better speed (650Mb) when I tired initially in Monterey. * SLEEP - this is in fact critical to me in a laptop, as I can't imagine sitting in the 3h meeting and when it goes to sleep - I need to hard-reset it to work again. Absolute showstopper. Even after installing CAFFEINE laptop still switches off the screen when closing the LID and the sleep problem occurs. * Laptop also does not SWITCH-OFF, but that's like the least of my current problems. I however think it is linked to the sleep issue. MacOS installed fine and booted OK. Pretty much all was working until I started testing sleep. I tested by inducing the sleep mode using: * the LID * Fn+INS * Sleep option in MacOS * MacOS timeout when running on battery. The behaviour was pretty much the same each time: * The laptop's keyboard lights up * CPU goes into overdrive * The screen remains dark and I can only switch it off by holding the power button. * It also does not switch off - when I shut down the OS, it looks like it's shutting down but the power light stays on - until, again, I hold the power button. When the laptop is plugged in to the mains and the screen times out (goes dark) - it wakes up fine. I guess in never actually goes to sleep - it just blanks the screen. Any other option: LID, Fn+INS, Sleep in the menu - same results as listed above, even when plugged in. TROUBLESHOOTING SO FAR: * I tried both BIG SUR 11.2.3 (to build my own USBPorts.kext) and MONTEREY 12.3.1. Same behaviour. * I tested both BIOS versions: 1.24.1 and 1.16.0. Same results, although on 1.16.0 I can't make WIFI work after downgrade. (downgraded from 1.24.1 - some modules like Intel ME did not downgrade!). I reverted back to 1.24.1 * I disabled the hibernation as per @Jake Lo guide and followed @Hervé BIOS settings recommendations. * I've seen a similar problem on the forum but the solution provided did not help (https://osxlatitude.com/forums/topic/17079-latitude-5490-no-sleepshutdown-under-monterey/) * I tried in OC 8.0 (after updating all KEXTs). I then dialled it down and tried in OC 7.5 and OC 6.8 - updating KEXTs along the way as Airportitlwm refused to work without updating it (and LILO as well). I always cleaned NVRAM between reboots. * I tried with both USBInjectAll.kext in Big Sur and with my own USBPorts.kext in Monterey - no difference. * I have no devices plugged into the laptop except Logitech trackball (to navigate on the screen as sometimes touchpad was not responsive) * I used various SMBIOS: from MacBookPro 14,2 to MacBookPro 15,2 - no difference. * I tried several different EFIs and started to build my own - but that's way to many variables to consider. Would take me 6 months. * Tried both Kabby Lake-R and Coffee Lake CPU IDs (recommended settings in Dortania guide) - same results. Currently running on EFI with OC 0.8.0 from @Jake Lo, posted here: My current EFIs: https://jarocki.cloud/index.php/s/HBLKnmRYCLMmsnC Also tried the following EFIs: * https://osxlatitude.com/forums/topic/16892-latitude-7490-unable-to-update-to-monterey/page/2/ * https://github.com/lohseng97/Dell-Latitude-7490-EFI-macOS-BigSur * https://github.com/Swung0x48/Dell-Latitude-7390-7490-Hackintosh-EFI * https://osxlatitude.com/forums/topic/17159-solved-latitude-7280-stuck-trying-to-install-monterey/page/2/ * https://osxlatitude.com/forums/topic/17142-latitude-7390-external-hdd-shown-as-internal/ * https://osxlatitude.com/forums/topic/17003-latitude-7280-sleepwake-issue/ * https://osxlatitude.com/forums/topic/16247-dell-latitude-7490-building-opencore-efi-for-big-sur/page/9/ Got pretty much same results on each. Sometimes had to change configuration to make the iGPU work or to make the WIFI work. LAPTOP: Latitude 7490 BIOS: 1.24.1 i5-8350U 32GB RAM (2400MHz) - perhaps too much RAM? Audio: Realtek ALC3246 SSD: Samsung 970 EVO Plus 1TB NVMe - perhaps incompatible NVMe? WIFI: DW1560 M.2 WiFi 802.11AC. Working but quite slow. I also have Intel 8265NGW but can't make it to work anymore with Airportitlwm. My IOReg file attached. MBP.ioreg Quote Link to comment Share on other sites More sharing options...
