Mojave on Biostar TH55HD Socket 1156

Removing _PRW methods from EHCx does prevent instant wake, but it also prevents any wake. Still looking for a way to wake from sleep without having to cold-boot with power button.

Installed a Xeon X3480 CPU. No system changes required and SpeedStep/CPU Power Mgmt still works perfectly. New CPU multipliers range from 9x to 28x (up from 9x to 24x with the Xeon X3450). Geekbench scores with Xeon X3480 (without TH55HD overclock enabled) are attached.

I enabled the TH55HD motherboard's automated overclocking (no-brainer, doesn't require any config changes). This old system is definitely worthy of a graphics solution for Mojave.

During software builds, it's not unusual to see this system clocking each core at 28x multiplier / 4.06 GHz.

Tried enabling "USB Wake from S3/S4" in BIOS and "zeroing" the return values of _PRW in EHCx and UHCx in DSDT. System still wakes immediately if a USB device is plugged in to one of the ports. With no devices in any USB ports, the system sleeps, but I can't wake it.

log show --style syslog --start "2019-02-08" | fgrep "Wake reason" shows no wake reasons.

Thanks for your post. Your experience may help me too.

Since 2 days I try to get my MSI H55m-E33 Board with an i3-530 and Intel Graphics to either boot

• the Mojave installer what got stuck with "This version if Mac OSX is not supported on this platform! Reason: Mac-F2238AC8"
• or to boot High Sierra Installer what got stuck with "Please switch to XPC..."

Can you do me a favor and upload your EFI folder as zip with everything included? This may help me for a new boot test.

Now that my config is stable and working well (except I can't wake from sleep), I feel comfortable posting my EFI. My full debug reporting files are attached.

Just upgraded my memory from 8GB to 16GB DDR3 1600 8-8-8-24 after observing (in Activity Monitor) that my software builds used 100% of available 8GB memory. Software build times have improved (reduced) dramatically! This old clunker is FAST. Total upgrade cost of this system was $138 (starting with old motherboard that I purchased from NewEgg as openbox for $50 in 2010, old Power Supply, Old Case, old GeForce 9800GT 1GB Video Card and old 8GB (2x4GB) Crucial Balistix Tactical DDR3 1600 8-8-8-24 LP RAM): 256GB SSD for $50, XEON X3480 for $63 and 8GB (2x4GB) DDR3 1600 8-8-8-24 Crucial Balistix Tactical LP RAM upgrade for $25).

The cost of the RADEON RX card to upgrade to Mojave will be well worth it.
