I installed the latest Catalina 10.15.5 on my m93p Tiny (same configuration as OP).
I used the EFI from the guide. Thank you for the guide and for the configuration files.

Everything works ok, even the sound, except:
1) The wifi because I don't have the supported cards (just purchased the BCM4352 from ebay), so that is not really a problem.
2) Real issue is the system is rebooting after wake.
I already replaced AppleALC, Lilu and WhateverGreen with the latest versions and did not solve the issue.
About 15 seconds after awake it just reboots.
Did anyone have this issue?
I browsed through the postings in this thread but I could not see anything about that.
Sorry if it has been reported and I missed.
Check your bios settings for CStates enable them.

Run Hackintool and rebuild caches, it’s in the utilities section at the bottom, the last one on the right.

Thank you Gigamaxx, for the reply and the guide.

I managed to find the problem. It turned out not to be a configuration or installation issue at all.
I am using an adaptor DP to DVI because I am using an older monitor for this build.
I remembered that someone in this thread had an issue with an adaptor for his monitor, so I
decided to test with a newer monitor using the DP connection.
Sleep and wake worked fine. The issue was because of the adaptor. Maybe because it is a passive adaptor. I don't know.
Otherwise, the older monitor works fine and the image is great.

So, if anyone experiences this issue of reboots after sleep the problem could be your monitor.

I had the same issue, its an issue with AppleAlc.kext and using a DP to DVI adaptor. You can actually fix the issue in clover configurator, snippet of the fix is below, credit to dognmonkey.

The Haswell HD4400 and HD4600 have kernel panic reboot after sleep/wake when using AppleAlc.kext (1.4.8) to patch IDT 92HD91Bxx sounds with Lilu.kext 1.4.3. The only way to work around this is to add No-hda-gfx=AAAAAAAAAA= in the device property.

Huge thanks to Gigamaxx - Got this working perfectly on a m93p with the 4590t quad core. Will attempt on a 4785t in a few days.

Thank you for pointing that out. The patch worked great.
I changed the layout id from the original patch in the Catalina post to 3 so the internal speaker would work.
Here is what I used:

<key>Properties</key>
<dict>
<key>PciRoot(0x0)/Pci(0x1b,0x0)</key>
<dict>
<key>No-hda-gfx</key>
<data>AAAAAAAAAAA=</data>
<key>alc-layout-id</key>
<integer>3</integer>
</dict>
</dict>

Now my M93P Tiny is perfect. Everything works great.
Thank you again to Gigamaxx, Xinliz and all others who contributed with information for this build.

Good Morning All,

Hope you are all safe & well.

I just did the 10.15.6 update and while the update went without issues it now takes forever to shut down or restart.

Has anyone else seen this and figure out what the issue is?

Hi Gigamaxx, can you help and explain me again how can I downgrade the Bios on this tiny Lenovo?
Since I've tried many times I can't get the bios to read the usb properly. I mean the Pc when booting see the usb but than no way to downgrade. In the bios I checked the downgrade option....

Try different USB ports first. Bios enable XHCI, don’t enable the USB power saving mode.

Post number 2 or 3 has a link to a github version. Install to a USB.

Droping a word to this thread, from google search.
I'm using m93p tiny since may '18, but i change to i7-4785t, the problem I face was proc temp, as we ( m93p tiny user) know, this little thing have a limited heat sink + blower fan. I used this machine as daily driver as a light developer. sometime cpu temp rech 74 - 75 degre ( Celcius ).

After read about what @Gigamaxx already done, I miss ssdt for specific processor, and thanks to him, now my tiny machine only reach max 70 degree Celcius. ( I'm using ssdtprgen to create .aml for specific processor)

Once again, many thanks to @Gigamaxx
