[QUOTE="PCRuns, post: 1882242, member: 407802"] Hi, I've been trying to use these suggestions here to upgrade this MacBook Pro to Catalina: [MEDIA=youtube]wxFzZWqoCng:514[/MEDIA] I have been successful on previous MacBook Pros. However, I am having major issue with the one I am working on. It was unable to install Catalina because it says that it requires APFS formatting? When going through setting up using macs Disk Management it kept saying that APSF was applied but it still never worked? It suggested that I install macOS High Sierra. This didn't work either. I then tried reinstalling the original macOS that was on it. However, I tried installing macOS 10.7.8 instead of macOS 10.7.5. This didn't work. I have been able to get back to macOS 10.7.5 through the "Option + Command + R" on startup. However, the blue time line finished immediately and says there is over 2 billion hours left for instillation? Then it says that "Can't download additional components needed to install Mac OS X".
