Hello all, Ever since updating to macOS Sierra, I've been having an issue with my 2TB Seagate desktop hard drive and my late 2013, 13" Retina MacBook Pro. In short, if the computer goes to sleep with the hard drive connected, upon waking the computer, I cannot eject the drive or use it without Finder crashing, forcing me to hard boot the computer. A few things I've tried (unsuccessfully) to remedy the issue: Reinstalled macOS Sierra Booted up using Command + R and ran first aid on everything (which found problems on the drive and fixed them, but the problem remained) Transferred my data to another drive, reformatted the drive in question. Tried to replicate the symptoms on an identical Seagate external HD I have - Same exact issues. Took MBP to Genius Bar, Genius ran full diagnostics - no issues found. Does anyone have any ideas on what could be going wrong here? It's driving me insane and I do not like having to turn my MacBook pro off by holding the power button a few times a week. If it's of any importance, the hard drive is a 2TB that's formatted to use 500GB as my Time Machine, and another 1.5 TB of regular storage. Thanks for reading!
