Question: Booting into Mac OS stalls at about 75%
I own (among other models) a mid 2007 iMac. (Yes I know it is 11 years old. But it does what I want) 20 inch screen Core 2 Duo t7700, 4Gigs DDR2. Besides upgrading ram to 4 Gigs, I swapped out the standard platter HD with a 250 Gig SSD. It has worked flawlessly for years. For the last year it has been used to watch movies and TV shows off my Plex server.
2 days ago I uninstalled Teamviewer because it was acting up and kept crashing. After I uninstalled it I rebooted the Mac and when the progress bar got about 2/3 of the way during booting the screen went off and back on, the progress bar went from black to grey and what I would call a progress wheel started spinning under the progress bar, then the screen turns off and back on every 7-10 seconds and it keeps doing that.
I figured TeamViewer pooched something so I cleared the PRAM and SMC. That did nothing, I checked to make sure the memory was seated properly by ejecting and reinserting the ram. I reinstalled the OS with the recovery partition, I even took the system apart and made sure the HD was connected, I resat the Video card and the CPU as well as the wifi & Bluetooth adapter. But even with all of that it still gives me the same issue.
And idea what is happening and a way to resolve the issue.
iMac, OS X El Capitan (10.11.6)
