You may or may not have heard of OpenCore Legacy patcher. Well its another way of extending the use of old macs all be it a bit more modern than what runs system 7. I have a MacBook Pro (late 2008) with 8GB of ram and now I am running Monterey on it and it runs buttery smooth, I have not come across any problems at the moment, The only thing I have a problem with is trying to clone the disk as I have a 250GB SSD and was going to upgrade to 500GB SSD. The disk clones okay with Carbon Copy but but it won't boot correctly from the cloned disk. I need to figure it out but I could just start from scratch with a fresh install on the 500GB SSD. Has anybody else used this patcher if so what are your experiences with it. Christopher. link to OpenCore https://dortania.github.io/OpenCore-Legacy-Patcher/SONOMA-DROP.html |

I have been using the OpenCore Legacy Patcher on a 2010 17" MacBook Pro. It is currently running Ventura. The clone is probably not booting because the files installed in the UEFI partition were not cloned. To rectify that boot from the installer (USB I am assuming), and use the Legacy Patcher option to reinstall the needed files to the partition. The Legacy patcher installs a more or less universal set of files to the UEFI, so it for the installing the files it does not matter whether your boot/install device actually matches the OS version you are installing the patcher to. And with the Legacy Patcher, you can update the installed OS the same way you would update a supported Mac. Overall it is just crazy how Mac-like the hacked patcher is. The patcher drops support for some things that Apple considers essential. I can not use side car for instance, and it will not run applications that require "metal" graphics. But all the basic day to day functionality for general purpose computing are there and do very well. I am very impressed with what the developers have been able to accomplish with this.

I should do more thinking before I post. If you still have the USB installer, you can boot from that and once it starts, you will have the option to boot into the Mac OS installed on the internal hard drive. Once you have used that to boot the OS on the internal hard drive, you can run the Legacy Patcher application from the internal hard drive. From the application you will be able to install the needed files to the UEFI as well as do any updates that might be needed to the OS on the internal hard drive.

Got it all working now with the new 500GB SSD. I just reinstalled it from the USB installer and it kept everything fine but now it boots okay. Christopher.

I use OpenCore on a 2011 iMac - runs Ventura very nicely. I don't ask much of this iMac just email, Firefox, podcasts, Apple Music. Oh, and Minecraft too. It all runs sweetly with only a few insignificant graphical issues that sometimes appear, e.g., some flickering in menus. The install was fairly easy, and updates are relatively simple to do on an ongoing basis as well. Love OCLP!
