Hi, I hope someone here can help me. I have a mid-2010 iMac. My hard drive failed and a tech person removed it for me. I bought a 32GB Cruzer Blade 323GB and installed a boot version of OSX High Sierra. I tested it on my MacBook Pro and it works. However, when I insert into my iMac I can't get it to work. The machine starts up and then I press the option key, but nothing. Just a black screen. After a short time I hear a fan noise. Inevitably I then have too manually shut down the iMac. Any ideas? Thanks in advance.

Hello and welcome.

High Sierra is the maximum version of OS X/macOS your iMac can run. Sounds like there may be more hardware issues than the HD.

Are you holding the Option key immediately after powering on, or after you hear the chime?

No worries.

Which model is the MacBook Pro that it works on?

-Is it an Apple keyboard?
-USB or Bluetooth?
