Guest Posted March 15, 2018 Share Posted March 15, 2018 Sure, my Dell has i7-4790, 3.6GHz, 16GB ram, integrated graphics. BT through a USB adapter. No wifi. Apple services all working except iMessage. 2 Dell monitors (P2314H 23-inch) managing 1920x1080. Hardly a gaming machine. and running latest version of HS (10.13.3) with no issues. First I upgraded the BIOS to v21 (now to v22 released in Feb). There are more sleep/wake options than in v03, which is where I started. This is probably worth the upgrade. Copy 09020A22.exe to a DOS-formatted USB drive and do a flash BIOS update http://www.dell.com/support/home/ca/en/cabsdt1/drivers/driversdetails?driverId=9GC60 In the bios - in addition to everything else:Performance - C-States control onPower - Deep sleep - Enabled in S4 and S5 (probably the default)USB wake support - enabledWake on LAN - LAN onlyBlock sleep (S3 state) - not checked Clover config: can't recall if any of these were selected by default or unnecessarily by me.Acpi: checked FixLAN, FixRegions, FixHeadersboot: -v -xcpm dart=0 kext-dev-mode=1, EthernetBuiltIn=YesKernal and kext patches: Apple RTC, KernalPm, DellSMBIOSPatch Couldn't tell you which is the secret ingredient, but I hope this helps. Any idea what DellSMBIOSPatch does? *** EDIT: Ha, scratch that. Just had a crash after sleep. Ignore my clover config advice because I suck. The bios update still probably a good idea. Maybe we need a new thread for Optiplex 9020 discussion. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted March 15, 2018 Administrators Share Posted March 15, 2018 DellSMbiosPatch is a fix for some dell models that truncate the smbios instead of showing the whole identifier like Imac11,1 would show up as maybe imac11 in about this mac Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 15, 2018 Moderators Share Posted March 15, 2018 Actually more for laptops SMBios like MacBookPro12,1 or something similar will get truncated to MacBookPro12 as Bronxteck said. Desktops' SMBios are much shorter and won't be affected. Thanks for the info, will give them a try. Link to comment Share on other sites More sharing options...
brousseau6933 Posted March 15, 2018 Share Posted March 15, 2018 Ok, you had a crash but is it always the case? In my case (and I would guess Jake too), kp is instantaneous when trying to wake the computer. And it's always the same kp with something related to acpi, in my case at least. The only thing that we don't share in common with you is the CPU: yours is an Haswell-refresh (4790) and ours are Haswell first iteration (4770). I also had BIOS 0A20 and now, 0A22 and the bug remains... Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 15, 2018 Moderators Share Posted March 15, 2018 No need of bootable USB to flash BIOS or Windows You could either place the exe in the /EFI directory or on any USB drive Select F12 at boot, Select BIOS Flash Update At the Dialogue box, browse to the location of the .exe Begin Flash Update. Done Anyway, updated BIOS and set BIOS settings as you mentioned didn't make a difference. Link to comment Share on other sites More sharing options...
