I've been googling and googling, but everything I have tried so far has not worked. I'm hoping someone here might know what's going on and/or have better suggestions for me. System Specs: MacBook Pro (Retina, 15-inch, Late 2013) 2.3 GHz Intel Core i7 16 GB 1600 MHz DDR3 Intel Iris Pro 1536 MB 500 GB SSD My biggest issue is that I don't know how to replicate my problem. It is so hit or miss that I don't know what I'm doing (or not doing) to cause the "freeze". The problem is, after working on my computer for a while, I'll close the lid or activate the screensaver and go do something else. I'll come back later, open the Mac, and the login screen pops up. I am able to use my mouse to click on the password box, I am able to use my keyboard to type in the password, but the process won't let me go further than that. I click "enter" to try and log in, or I click the arrow next to the password box, but the computer acts as if I haven't done anything. The only way I'm able to get past this is doing a hard reset. This is extremely frustrating, especially if I had something from work up, or if I had some documents open, etc. I feel like it has gotten worse over the last few weeks, but there has always been a delay at the login screen. I can handle a few seconds delay, but I can't handle having to turn off and on my computer every time I activate the screen saver or put the computer asleep. I do have a password required for login and screen saver access, but that's because I often leave my computer on at my desk at work while I go get a drink, take a break, etc. Any ideas, links, insight?
