Oh I’m on a MacBook Pro 7,1 and the WiFi completely went out. It works on Mojave so what’s the issue I’m on 10.15.7 I have tried the dosdude patcher as well again.

If anyone know to get WiFi back let me know on this form. It was working fine until this morning except a few issues. Mojave works well so I know its just Catalina.
 
Thank you everyone like really

Well, I use 2018 because its the one I have and (I may be wrong here) I bellive more recent software will need more graphical power (and the infamous metal requirement) and I just have the Intel hd 3000. For my needs 2018 is ok.

As far as I can tell my mac temperature is ok, as I said only safari makes the fans turn on (and when this happens it gets hot), I just use Firefox now and I’m quite happy with it.

I had some problems with hight temperatures in the past, had some usb problems with Parallels but since upgraded to 10.15.7 those problems were gone.

In my previous post I forgot to say, I’ve two hp w2007 monitors connected (one via mini display port and one via usb adaptor), and even so my sistem is going very well.

I had a very good experience with @dosdude1 Mojave patcher, when moving to Catalina had some problems, but now I’m really happy with the machine (I think I will not upgrade anymore)

Regrading your monitors. Do you have black bars when you use external monitors?

When I connect to an external monitor any app will get its tool bar or certain areas to be blacked out. I have to use Color LCD profile to solve this. I don't like colors on this profile. So I was wandering if you have same problem and how to solve it?

If anyone knows how to solve this. please help me.

No I haven't had issues with external monitors. I did have issues with wifi but that got fixed after following this recommendation. I still have photoshop 2020 which works perfect for me. Its the cloud one which I hate, I just disabled updates. Firefox or Firefox esr is the way to go. Google chrome I can't just stand anymore even on my modern pc.

I had the same issue after upgrading to 10.15.7. I found that I could manually attach to the wifi network using sudo networksetup -setairportnetwork en1 SSID PASSWORD. This article helped reset the Wifi settings so it would join my home network automatically again.

Apparently I heard something about data mining on Google chrome as well which explains, my high cpu and memory usage. Even my 4 core i5 pc suffers with Chrome. Memory isn't an issue either. It just uses high cpu usage even without extensions. I even tried to force hardware acceleration in chrome://flags.
 
Other than that Catalina works perfect on my mid 2010 MacBook. I found the assentbot is working on Big Sur. Acceleration has been achieved on the Nvidia 320m. He has finals to do so it might be a while before it gets released.
 
Which means skylight patches will be needed
So that means I can hold onto this computer as long as I can.
 
Most likely until the intel machines get dropped. But acceleration patch for Big Sur on Nvidia Tesla is coming out soon :). Not sure about intel hd 3000 computers. You might have to wait a bit longer.

No, i don’t have any black bars. My profile displays are automatically selected and no strange behaviours are present at all. Does your display profile appear? Maybe you need to install some driver for your display?

Can someone help me understand the difference and then the pros and cons of Open Core vs. the Catalina Patcher from DOSDude1?

I've got a late 2009 iMac 27" with the i7 and I upgraded the HDD to a Samsung 860 EVO 1TB SSD.

For the past few months, I've been using the Catalina Patcher and have become curious of Open Core.

Last night, I used the Dortania online guide for Legacy Macs to get Open Core up and running in about 3 hours. Given that the guide is written for Open Core for Big Sur on legacy Macs, I omitted a couple of things that read as if they were Big Sur specific since I've got a non-Metal GPU and everything I've read says stay with Catalina or lower.

Anyway, I've got Catalina 10.15.7 running under Open Core on my iMac and I still have some fine tuning to do to get the onboard Ethernet NIC and Wi-Fi working. I couldn't help but notice that graphics-wise, the UI appears to be a little laggy (i.e. moving windows around is slow) compared to how things looked and felt with the Catalina Patcher.

Questions:

1. Now that I have Open Core installed, should I apply the patches from the Catalina Patcher to fix Dark Mode, etc.?
2. If I can't use the Catalina Patcher patches to fix, how to I go about fixing these things with Open Core?

Thanks!

Yes I see my display profiles being added and selected, and that's what cause the black sections.
Drivers? Can you explain more? sorry I don't have a lot of knowledge.

I don't know exactly what more I can say, does you external monitor came with some kind of cd with software? If it did maybe it has some additional drivers to install

This is my configuration

1. You definitely should because. I'm not sure what guide you followed, but OpenCore doesn't do anything on it's own and it probably wasn't intended for you to use it on your Mac, which needs that a lot of patches. Some of which I don't think are even possible on OpenCore only.
2. As I said above, there are some things that I don't think you can actually fix with OpenCore due to the way it's designed and the patches it's intended for.

Unless you have a good reason not to, or a newer Mac that doesn't need as many patches, I wouldn't recommend you use OpenCore. Just stick with one of the many patcher tools that have been made by me, dosdude1, and others. I hope could help with your question.
