I kinda used this thread as the catalyst to go ahead and upgrade my base 27-inch 2019 (only bought last week to be fair).
I wasn't convinced that the i9-9900KF or other higher spec processor would work. Its a big lay out for a punt.
So I opted for the i9-9900K. £450 new.
I opted for this processor due to this being an option straight from Apple. Anything googled online only really suggests the board supports 4 options.
I also upgraded the RAM to 64gb but while is was in, installed a 1TB SSD and 128GB PCIe blade (that I had spare which came out of a 2015 MacBook Pro).
I have to say, not the easiest job.
Two key areas that are a headache:
1. refitting the tension spring to the back of the CPU.
2. Refitting the screen (mainly because it was my first attempt).
However, I have to say, the machine fired back up first time, absolutely no issues.
Key point - The fusion drive, for obvious reasons, splits. Again a noob to this, but actually wasn't so hard to fix. I'm an OCD kinda guy and hated having a separate SSD & PCIe drive. I want the OS to run from the blade and the crap loaded onto the SSD.
Easy process.
Boot from your previously cloned externally HDD. Note - the clone on this drive automatically splits into two volumes when it copied my original fusion drive.
Go into recovery mode at boot up. Takes a few minutes to boot.
Run terminal from the utilities menu and the "diskutil resetFusion".
Reboot the machine from your external drive and clone back onto your newly built fusion drive. You can rebuild a fusion drive with SSD & PCIe.
Job done.
I have to say, the machine is running well. Geekbench scores are pretty much inline with average scores for this new spec.
