I removed all of these and changed it with iMac14,2 Board-ID but still shown NVIDIA Chip Model 7 MB.Change to iMac14,2
Just 3 Step and No needs Change to any Mac type..iMac,etcHi there all;
This is my 1st post so hopefully its in the right thread - apologies if not. I need some help and it seems that this is a good place to ask!
I am trying to setup an egpu (purchased from Bizon) on my imac. I contacted Bizon and am awaiting their reply. But any help would be appreciated.
I have an nvidia 980ti in the egpu. The Bizon prefpane 'install wizard' came up with an error when it looked for a 'web driver'. So being impatient, rather than wait for Bizon to get back to me I looked for the correct nvidia web driver for my version of OSX
(yosemite 10.10.5.) I went ahead and installed the driver after checking
that it was OK to install a driver for a non-existent card... as the egpu unit was not yet hooked up.
However on restart after install the imac hangs about a quarter of the
way into the startup progress bar. I assume this is because of driver
incompatibility? I tried resetting pram (cmd-opt-p-r) but it still
hangs. The only thing I can launch is OSX recovery which has only system
restore options. And single-user command line. And of course I can see the drive in target disk mode from another mac. Safe mode won't boot.
Please advise what I should do - I need my computer back! Basically I'm guessing I need to uninstall the nvidia driver - either via command line in single user mode - if any tips on that please provide a step by step as I'm not confident in messing with command line) OR by hunting down the files in target disk mode and deleting them.
imac 27" late 2013 / 3.2 ghz / native card is NVIDIA GeForce GT 755M
Many thanks in advance for any tips,
