These requirements are the same for Sierra and High Sierra IMO.Īssuming it is indeed a MacBookPro5,x model, the process is as follows:ġ) Download dosdude1's High Sierra patcher.Ģ) Follow the instructions to create a USB drive with the patched macOS installer on it.Ĥ) Plug in the USB drive and turn on the computer to do a cold boot of the Mac, while holding down the OPTION key.ĥ) If the USB drive can cold boot, you should see an orange external drive listed. Overall, I think 10.13 High Sierra is the superior upgrade on these old Macs, as long as they have SSD and sufficient RAM, which is bare minimum 4 GB, but preferably 6 or 8 GB. Plus that bug is present in a couple of fully supported Macs too, so it's not the fault of the unsupported install. That bug is completely absent in 10.12 Sierra, but I've only seen that bug in the wild in real world usage twice in 9 months using High Sierra on two such old machines, and in both instances it wasn't a big deal. Most people will never or only very rarely see that video bug. 10.13 High Sierra also has a h.264 video bug that only occurs under very specific circumstances.
It depends on what software you are running. High Sierra has more up to date features and software than Sierra, but is also less compatible with old legacy software.
It will show you the specific model number, something like "MacBookPro5,5". And then click on the button that says "More Info" or "System Report". Click on the Apple in the top left corner and go to "About This Mac". Click to expand.Since you’re new at this, you would best tell us the exact model.
