Hello, all, this is my first real foray into mac computers, needing some assistance with a used macbook I bought (A1342, 2.4ghz)
Was bought used, would not start up initially. After a few attempts, it booted once (High sierra installed) but was incredibly slow (30-40 minutes boot time, ~60 seconds just to switch between windows). tried to restart, and couldn't get it to boot again, was stuck on loading screen with progress bar full. I also had an SSD I had planned to upgrade to, so I just ignored it, made a bootable USB drive, and installed the blank SSD.
After this upgrade, I can't use any alternative boot method, startup utility will not appear when trying to boot from USB drive (option+power), just loads a blank white screen with the cursor, which I can move with the trackpad. Any other boot method results in the flashing question mark folder displayed on screen (single user mode, recovery mode, etc.)
I have reset NVRAM, which appears to work, but does not change results. Any ideas? I could clone the original boot drive, but didn't want to keep whatever may be slowing down the system, so I preferred the thought of a clean install.
