I can't even remember the last time I had a kernel panic. I'm typing this on Snow Leopard right now. On the subject of OSs and stability, Snow Leopard is still my favorite. Catalina seems like the minimum that might have a chance at 4K video. So I don't think High Sierra is a good option for 4K video. But despite the 17 inch screen size, it's just barely has enough resolution to watch 1080p videos, and playback on any video over 1440p looks like crap. HD videos on YouTube look fantastic on it. My MBP is running High Sierra which is great. From everything I have read, only the most recent Mac OS versions will support 4K playback in a browser. Unfortunately, I don't think I have a lot of choice but to upgrade if I want to watch YouTube videos in 4K. That's too bad about Catalina and Big Sur. But when I have some more time I'll try again, and double check the instructions. Yeah, I think I followed the instructions right. Even on my supported MBP, it had kernel panics related to screensaver/sleeping. I will say that Catalina was somewhat buggy. Looks like your computer saw it, it just had issues mounting the image? I take it the format/initialization of the disk were all done following the patch instructions? But I agree that it shouldn't matter as long as the computer can see it (And I believe I actually used a microSD card). That makes sense as you may only have the one computer you're trying to upgrade.Īnd yes - I've always just used a USB. Although, I don't know what difference that would make. So it seems to be a pretty universal installer.ĭid you use a USB drive for your bootable disk? I used an SSD drive, because I didn't think the old Mac Pro could boot up from USB, but maybe I should be using a USB drive for the installer instead. Then he uses that to install Catalina on the same machine. Because in his tutorial video DosDude uses a 2009 MBP running 10.11 El Capitan to make a USB drive installer. But I'm just using it as a Time Machine server so. Not to mention not everything still works. I don't remember it being flawless when I did it. Of course, you're doing something unsupported.so some tweaking is going to be expected. He seems to have some good documentation if you want to give his patch a try. I believe I used my MBP that was running Catalina at the time to create the install disk. I have a Mac Pro 4,1 (2009) that is running Catalina. It's driving me nuts.ĭon't you need the host (the one making the bootable disk) to be on the same version as the one you're trying to install? Has anybody here tried this before? I would appreciate any sugestions. Then I will upgrade it to 10.11 El Capitan, and see if the Catalina Patcher will work that way. But unless somebody can give me an idea on how to solve the above error, I think my next step will be to install 10.6 Snow Leopard on the Mac Pro. My plan was to put the installer on an SSD and then install it into the Mac Pro for the final install. I have tried to create the bootable installer on a MacBook running 10.6 Snow Leopard and on a MacBook Pro running 10.13 High Sierra. I have been getting endless errors while trying to create the bootable installer, and I can't find a lot of documentation to fix the problem. I'm trying to upgrade my 2008 Mac Pro with MacOS 10.15 Catalina, so I can install a new video card, which will hopefully let me watch 4K video. Does anybody have any experience using macOS Catalina Patcher to install MacOS 10.15 on an unsupported Mac?
