Given where you posted, I am going to assume that you have a USB with DosDude's MAGIC! ALCHEMY! Look under applications and folder within a folder... look for the post install utility. With a little bit of luck the utility will run, reboot, and all your troubles will go away. From my point of view, stoping the auto switch to low performance video card helped. Good Luck!

Hi!

I did a fresh Catalina install on a new SSD, with dude's patcher tool. All kext patches applied for iMac 8,1.

Hardware: iMac 2008 24", core2duo 8335, 4gb ddr2, 256gb sata ssd

Everything works fine, I just found some minor problems.

-If I let the Mac go to sleep, after wake the entire OS is laggy, I mean all the animations, videos, etc, but after a restart everything's perfect again.

-I can adjust the brightness settings manually, but its on 70% by default. If I set it to 100 with the slider, I can see the change, but the slider goes back to 70% (without taking down the actual brightness). I have to set the brightness to 100% after every restart/sleep/screen saver. Also tried reinstalling the brightness patch, but did not change anything.

-I can't get microphone signal. I did open up the mac's case, reseated the microphone, and the cable, tested the cables for continuity, and everything looks fine (also the iSight camera works fine). Tried also with my iPhone X, the Catalina downloaded the support files for the phone, I can see it, and I can enable it as a microphone when plugged in with usb, but no input signal. Tried enabling dictations, opened midi app, i did set up iPhone as primary input for mic, but no signal. I also tried in QuickTime voice recorder, but its totally deaf.

None of the problems above are serious problems, but maybe someone had these too, and has ideas how to solve them.

Thanks in advance!

Hi guys!
i'm triyng to install catalina on my 2007 macbook 4.1 with the RMC patcher (the one the support the macbook 4.1).
The RMC Site is in 404 now and i can't find a guide to install it.
Following what writed on GitHub page i selected the scrip and installed on a new partition
restarted the Mac and installed Catalina like a new os on a new partition.
But after that i can't startup the new partition (is disabled).

How che in correctly install Catalina?
thanks in advice

1. Because all is working perfectly without it—don't fix things that are not broken?
2. This is a remote-located Mac in a production environment not a CS plaything; IF the patch caused a problem it would have a massive effect on workflow and lost income.
3. When a few people here post that is has been problem-free on the same Mac model, it'll be installed when the Mac is not in the middle of work.
4. Yes, I should have remembered the Patch updater method, but sarcasm is deprecated when you don't know the full story.
5. See post 12514 above—there is some doubt that the patch works 100% at present (no disrespect intended Colin).
This is supposed to be a HELP board, not a place to throw shade with an eyes-turned-up comment. If that's what it's become, I'm out of here.

You are mixing things up. I asked questions regarding your intentions and offered a honest solution.
I was not the one with the eyes-turned-up, so I think it is a bit unfair to throw that comment to me.
But anyway, not taking it personally, just wanted to clarify that. My main reason in answering was to show a solution...

Hi Guys - sorry if this is a dumb question. I have 10.15 beta running on mac mini 5,1 - I believe Dosdude's latest patch tool will upgrade it to 10.15.7. If I go ahead with the usb installation, will it be a clean install or install over the top of my previous version? I definitely do not want a clean install as i want to keep my files, programs settings etc. Thanks for any guidance. I watch the TuT video and it looks like a upgrade from a previous version but wasn't sure.

Yes, Kosiko, my apologies, the eyes-turned-up remark was not intended for you.

Yes you can install over your exisiting macOS Catalina without doing a clean install but still need to do thepost install patches afterwards

Darn, it's so hard to test solutions for this issue, as it happens so sporadically. I'm only able to make it happen a single time after a clean install on any of my machines.

The crashing behaviour on my iMac 11,1 is after every reset SMC. The problem is not a show-stopper but is a significant nuisance – it affects key apps: MS Office, BBEdit, Banktivity. Ah well, maybe I should let the moths out of my pockets and get a newer iMac. I'm experimenting:

• Using an Admin account seems to make no difference but, an app which crashed once on one account works from another.
• BBEdit and Banktivity don't crash after a re-start.
• MS Word crashes after a re-start. Takes one or two crashes before it works.

Cheers.

For the iMac 11,1 (Late 2009, 27" i7-860) - is an updated Bluetooth/Wi-Fi module absolutely needed for a patched Mojave install? Or just if I want/need features like Handoff, etc.?

I have a K2100M en route so I can have Metal compatibility.

No, you can use it without the BT/WIFI upgrade, but I would strongly recommend it as it makes the iMac nearly 100% compatible.

It is done quickly, well documented, not that expensive when getting the parts online, and the iMac will be open anyway when changing the GPU.

Office 11 not supported in Catalina. Not a patcher issue.

Not sure if anyone else is running into this. I have a MBP5,4 that had been working with no issues with Mojave, then upgraded recently to Catalina 10.15.6. No issues whatsoever with wifi.

When 10.15.7 came out, I did an inplace upgrade using @dosdude 's (thanks!) tool. Upon restarting, it seems that wifi is not not able to find my SSID and will just fail after a while.

However wifi still works if I do the following. I need to start the Wifi diagnostic tool and scan for networks. I'm then able to join my regular SSID. Strange bug

I've been trying to get my 3,1 to Catalina using the dosdude patcher. According to his website, I should be able to do it and yet I can't seem to get a stable install. I've only gotten one install through 100% (through setup all the way to a desktop screen) but it crashes extremely frequently. I have one ssd mounted on a PCIe and another installed in a regular HD slot. For the other 49 failed installs of catalina, they fail either during the install process or install almost completely ("about a minute left") and then crash. However, the volumes are recognized as startup disks with 10.15. If I choose it as a startup disk or run the post-installs and do the same, I'll see the APFS fix and then the computer crashes and turns off. Any idea what could be the reason why? Or did you do anything differently to get yours to work? Really appreciate any help you can give.

Same experience here and at point of selling MP3,1 as a result.
Are you installing Cat to SSD in regular HDD slot or to PCIe card?
Have you tried flashing 3,1 bootrom to support both native APFS annd NVMe (assuming SSD on PCIe is NVMe)?
Also, what RAM configuration gives 18 GB?

Two ideas here, both covering the non-bootable APFS that Catalina seems to install:
- you could try to use the dosdude1 patcher to _only_ patch the APFS issue (de-select all other patches)
- use the APFS ROM patch to deal with it permanently (the tool itself has to modded slightly to accept the 4,1 as
a valid patchable machine - have done it successfully and it´s somewhere in the posts here)

good luck

The topic of enabling Safari extensions has been mentioned multiple times in this thread so I believe it is relevant to mention that I believe I have found a way to enable extensions by editing a .plist file.

I started a new thread about it here: Manually enable Safari 14 extensions

Gave my 3,1 with a HighPoint 7100 PCIe card with NVMe Samsung SSD a last chance and it did install OK.
Did NOT use APFS booter patch because this 3,1 has APFS and NVMe bootrom modifications and also set Autopatching to off when creating the USB installer with the 1.4.4 Patcher.
After the install and reboot, used the Option key to get to the patch options and manually patched with the video legacy patch and AMD SSL patches off. Also set the WiFi Broadcom patches to both off because have Wifi/BT 4.0 LE card installed. Rebooted with cache rebuild option checked.
So it is possible.

Hello,
My iMac late 2009 (GPU : Nvidia GTX780M (@Nick22 flashed) METAL Support) works well under Mojave.
I want to switch to Catalina, and i do not find how to do not install "Legacy video card patch" dosdude1's patcher Catalina.
I tried several things:
1 - Uncheck "Legacy video card patch" in the post install tool at the end of Catalina installation (by holding down the option key ).
2 - I used @Ausdauersportler 's method modifying the "macmodels.plist" file of the Patcher Catalina.
With these 2 methods "Legacy video card patch" is always installed.
What i'm doing wrong?
