I then re-created the Mojave USB using the patcher, booted up the MBP8,1, added a new APFS volume using Disk Utility on the SSD and ran the installer for what seemed like the 50th time. To check the box for "Yes, I have a working High Sierra system on this SSD" before trying Mojave again, I successfully installed 10.13.6 on the SSDġ5. Fortunately I had another (non-working) MBP8,1 (Late 2011) on hand, so I pulled the SATA connector (with IR sensor and status indicator light) and installed it into the working MBP8,1.ġ5. After further research I found many answers to bizarre SSD behaviour in the MBP8,1 (and others) pointing to a suspect SATA connector.ġ4. I then tried installing Mojave (Unsupported) onto the MBP8,1 using the original 320GB HDD and it actually worked - all signs started to point to an incompatibility between this specific SSD and the MBP8,1ġ3.
The SSD ran El Cap perfectly in the MB5,1, so I was back at square one.ġ2. I assumed the SSD was faulty, but to test this theory, I installed it into a MacBook5,1 and installed El Capitan (Supported) onto it.ġ1. Thinking it must be an APFS issue with this Mac, I reformatted the SSD as HFS+ and witnessed the same issue - I tried several times, but there was no way the High Sierra installer would work with this SSD.ġ0.
#MAC OS 10.14 NVIDIA WEB DRIVER INSTALL#
High Sierra (Supported) installer began OK, it copied the install system onto the SSD, but failed to startup on the first mid-install reboot ( circle with line through it) - enabling verbose showed missing boot.efi related errors.ĩ. I decided to give up on Mojave and tried installing High Sierra onto the SSD as a supported installation - I had not yet witnessed this SSD running ANY OS.Ĩ.
I tried many, many things to resolve this and couldn't get anywhere. Enabled verbose boot mode and witnessed boot.efi related errors - it seems the Mac couldn't find the APFS Preboot volume.ħ. Upon reboot, I was getting a circle with a line through it - no boot.Ħ. Reinstalled SSD, formatted as APFS and attempted reinstall of Mojave with the patcher.ĥ.
#MAC OS 10.14 NVIDIA WEB DRIVER UPDATE#
Reinstalled original HDD (HFS+) and installed High Sierra 10.13.6 with all the latest security updates to get the latest Firmware update for this model.Ĥ. Installed Mojave (Unsupported) 10.14.1 onto a new SSD, formatted as APFS using the Mojave Patcher 1.2.3 with all the relevant MacBookPro8,1 patches applied.ģ. Many thanks and for persevering with me to get this installed.ġ. Well after a few weeks of trial and error, I finally have Mojave installed on this Early 2011 MacBookPro8,1.
