[Solved] E6220: Unable to continue Catalina 3rd stage install

[Growtopia Jaw]

I followed Hervé’s guide on installing macOS 10.15.4 Catalina. The installation boots fine during the 1st stage (startosinstall) and 2nd stage install (reboot and continue). I got an error during the 2nd stage install but I think that shouldn’t be a problem.

 

 

I rebooted the laptop and continued with the 3rd stage (setting up user account etc.) but was unable to do so.

 

 

I can move my cursor but I am unable to boot into the desktop. This is really weird since I am stuck in console but the cursor works. If I click on anything, the cursor disappears.

 

 

I created the ssdt.aml for my i7-2620M using ssdtPRGen. DSDT.aml is taken from Hervé’s E6220 macOS High Sierra bootpack and SSDT-EC.aml is taken from Hervé’s E6220 macOS Catalina guide. I removed those extra SSDT-*.aml from the macOS Mojave bootpack as those caused kernel panics. My Clover files are attached.

 

Edit: This time, there is a voice asking me to “use voiceover to setup the mac”. I have no idea how to continue when I’m just stuck in the console.

Sorry but you claim to have followed my guide when you clearly did not.

 

Apart from the required change of CPU PM generated SSDT, why don't you just use the packs I posted?

• given that the E6220 can run macOS without a patched DSDT, the config of my packs does not load any and uses patched SSDTs instead, it's far more efficient; your DSDT is therefore totally ignored.
• if you manually call for your patched DSDT, it'll clash with my config and some of the SSDTs of the Mojave/Catalina packs I posted; granted you opted not to use those tables unfortunately.
• you appear to have opted for a bastardised setup derived from my packs; you should refrain from doing that kind of stuff.
• you took the Clover config I posted but not the SSDT tables nor the posted kexts set. As such, you're ruining and invalidating the ACPI settings of the config (renamings, patches, SSDTs injections) and missing essential kexts such as Lilu, WEG or AppleALC.
• you've ended up with a messed-up and unsuitable Clover arrangement that just won't work, forget it. 

 

If you want to use my guides, please follow them to the full and do not butcher things. This being said, if you were following my guide and installing Catalina from an existing Mojave installation, why install 10.15.4 and not the 10.15.7 version currently offered by Apple for download? Unless you're fully experienced at it, you'd find it awkward to update from Dosdude1's patched 10.15.4 to vanilla 10.15.7 that'd need re-patcinhg thereafter. But it's up to you, have fun!

NB: the bless-related error message at the end of the Catalina installation can be ignored. It's something that many people get with Catalina from 10.15.4 and I get that too. Catalina still boots afterwards and runs perfectly (with a correct setup of course).

Unfortunately, it still doesn’t boot to the desktop. The voiceover audio is still there but after I wiped clean my Clover directory and replaced all those tables and kexts as you've suggested, the mouse cursor doesn’t show up anymore.

 

 

I've attached my Clover folder just in case.

'beats me. No issues with Catalina 10.15.7 (build 19H2) downloaded from AppStore and patched with Dosdude1's patcher for 10.15.7.

[Growtopia Jaw]

Alright then. I'll try with Catalina 10.15.7 and report back here if there's any issue.

 

Edit: It seems that the latest downloadable Catalina is build 19H15. I hope it wouldn't cause anything unexpected.

[Hervé]

It sure was 19H2 last week after I installed it but whatever you say and it doesn't matter anyway.

You don't seem to run High Sierra with graphics acceleration so I'm tempted to say that you don't even have a sound base for anything else. I would suggest you start by installing Mojave as per my Mojave guide by following to the letter, then upgrade from Mojave to Catalina as per my Catalina guide. Good luck.

I’m not sure if this is a miracle or what. First, I’ve managed to boot the Catalina installer off USB and got it installed. I’ve successfully completed all 3 stages of the setup with only DSDT, ssdt and SSDT-EC. I’ve modified the default config.plist that came with Clover. Kexts are exactly the same as the ones found in the E6220 Mojave bootpack.

 

SMBIOS is MacBookPro9,1

 

Not really sure if this is reproduce-able but I will attach my Clover folder once I get everything set up.

 

 

 

 

Against all odds, everything works fine.

 

Edit: I've tried this exact method with macOS 10.15.4 Catalina but it won't work except for stage 1 and stage 2 install while the stage 3 install stucks at console with cursor movement and voiceover audio. I'm currently running macOS 10.15.7 Catalina build 19H15.

[Hervé]

You sure run Catalina but without graphics acceleration, presumably because this is a plain vanilla install, so it's kind of useless. So, no, you will quickly find that everything does not work fine...
